Dear Reader,<br />

We often see parallels drawn between construction<br />

and the automotive industry, especially when it<br />

comes to mimicking the car-makers’ levels of<br />

efficiency and low waste through the adoption of<br />

“Modern Methods” -but a very uncomfortable<br />

analogy has emerged since our last edition.<br />

VW has been heavily criticized after US authorities<br />

exposed its use of ‘Defeat Software” to conceal the<br />

true levels of pollution emitted by millions of the<br />

company’s diesel vehicles, landing the company<br />

with massive compensation claims from<br />

purchasers who rightly feel duped, and slashing its<br />

stock market value.<br />

I often buy shares when a blue chip company takes<br />

such a hit, but this time I fear there is worse news<br />

to come, while it also makes me ponder the<br />

increasing amount of reports I am seeing about<br />

new properties drastically underperforming in<br />

terms of their energy usage. It seems in such areas<br />

as cold-bridging and preventing air leakage, our<br />

housebuilders are struggling to get things right in<br />

practice.<br />

We are a long way at present from seeing<br />

disgruntled home-buyers starting class actions in<br />

the courts, but some kind of fiscal punishment<br />

from Government is much easier to imagine.<br />

Almost certainly, increased use of offsite<br />

technologies will help close the performance gap<br />

between design and o<strong>cc</strong>upant consumption.<br />

Meanwhile, with 38 of Britain’s 43 air quality zones<br />

exceeding EU safety limits for nitrogen dioxide, and<br />

air pollution estimated to be responsible for<br />

28,000 deaths a year, perhaps we should be<br />

making more use of products such as the coating<br />

to roof tiles which digests NOx, and also try to<br />

develop new homes in localities that will minimize<br />

vehicle usage.<br />

Yours sincerely<br />

Smart Cities, Big Data &<br />

the Built Environment<br />

The School of the Built Environment (in<br />

partnership with School of Real Estate<br />

and Planning) has recently won a<br />

prestigious grant from the RICS Research<br />

Trust in its special 'big data' call. The<br />

research (which is led by Professor Tim Dixon<br />

with Professor Martin Sexton and Dr Jorn<br />

Van de Wetering) will examine the drivers and<br />

barriers for big data platforms at city level in<br />

the UK.<br />

The smart city model provides huge<br />

opportunities to create added business and<br />

economic value from the integration of big<br />

data, covering many areas of the built<br />

environment. These include data relating to<br />

buildings, land use, planning, environmental<br />

data, health, economy, and energy.<br />

“More offsite” says<br />

build systems<br />

manufacturer<br />

The UK construction industry will benefit<br />

from increased opportunities for<br />

professionals to develop their<br />

knowledge of offsite construction, a<strong>cc</strong>ording to<br />

John Smith of Stewart Milne Timber Systems.<br />

Head of Technical, John Smith, believes that as<br />

more professionals are given the opportunity<br />

to understand offsite construction’s<br />

advantages and the latest developments which<br />

might assist them, the industry as a whole will<br />

benefit.<br />

To contribute to this, Stewart Milne Timber<br />

Systems offered a CPD session at its Witney<br />

facility in September, which was hosted in<br />

partnership with the Structural Timber<br />

Association (STA) and was free of charge to<br />

housebuilders, quantity surveyors,<br />

construction managers, directors, and<br />

affordable housing providers. It carries official<br />

CPD-a<strong>cc</strong>reditation for Royal Institute of British<br />

Architects (RIBA) members and included UK<br />

building industry “needs more offsite<br />

construction CPD” says the leading build<br />

systems manufacturer.<br />

John Smith said: “We believe that offsite<br />

construction has an important part to play in<br />

shaping the UK’s construction industry in<br />

coming years, and will continue offering CPD<br />

opportunities such as this in future. We expect<br />

to see similar offers from the rest of the<br />

industry as more professionals begin to<br />

employ offsite construction methods.”<br />

Researcher looking for ways to build a million new<br />

homes<br />

ALoughborough University researcher, engineer Ron Lang, hopes his study into house<br />

construction could revolutionize the way homes are built in the UK. His research is in the<br />

final stages of a four-year project looking at alternative methods of constructing<br />

housing.<br />

Whilst many researchers continue to look for ways to move the production of houses away from<br />

site and into factories, Ron believes there is a solid case for developing traditional methods.<br />

To identify alternative construction methods, six full-scale test walls with varying specifications<br />

have been constructed at Loughborough University’s School of Civil and Building Engineering.<br />

The walls were constructed under site conditions to allow Ron and his team to assess the build<br />

process for each alternative solution.<br />

He said: “If we can simplify on-site construction, we can improve the quality of our homes, speed<br />

up the home-building process and help the government to achieve its target of one million new<br />

homes in England by 2020.”<br />

The project is jointly funded by the Engineering and Physical Sciences Research Council (EPSRC)<br />

and Leicestershire-based company, Aggregate Industries (part of the LafargeHolcim group).<br />

Industry support has also been received from Gusto Construction, Tarmac Building Products,<br />

Forterra (formerly Hanson Building Products) and Low Therm Solutions.<br />

Builders bin the pub<br />

Forget the pub, white van men are more likely to be found in the gym working out than drinking<br />

pints, a<strong>cc</strong>ording to a new survey.<br />

A study of 1,000 tradespeople* by IronmongeryDirect, online and mail order supplier of ironmongery<br />

products to the trade, found that a substantial 69% of tradesmen don’t go to the pub that often, and 10%<br />

never go. 17% go once or twice a week but only 2% go most days and the same percentage every day.<br />

However, 32% claimed that they regularly go to the gym and exercise, and 50% said they are watching<br />

their weight. 13% are currently on the Atkins diet, 13% are using Slimming World, 11% use Herbalife, 8%<br />

are on the 5:2 diet and 5% are with Weight Watchers.<br />

The survey was conducted as part of IronmongeryDirect’s ‘The real white van man revealed’ campaign,<br />

which aims to shed the stereotypes often associated with tradespeople.<br />

Work starts on new a<strong>cc</strong>ommodation for Army<br />

medics<br />

The Defence Infrastructure Organization (DIO) has started work on new en-suite single<br />

living a<strong>cc</strong>ommodation for Army medics at Keogh Barracks in Ash Vale, Surrey.<br />

The £3.9 million project is being carried out in partnership with modular construction<br />

specialists, Rollalong, and is planned to complete in summer next year.<br />

Once finished, the 70-bed facility will conclude the modernization of junior ranks<br />

a<strong>cc</strong>ommodation at the barracks. It follows recent works to convert existing a<strong>cc</strong>ommodation<br />

from multi-o<strong>cc</strong>upancy rooms to single rooms.<br />

It’s part of a wider £50 million redevelopment project to enhance the barracks over four years<br />

for its new o<strong>cc</strong>upants.<br />

4 Armoured Medical Regiment (4AMR) relocated to the site earlier this year from nearby<br />

Normandy Barracks in Aldershot, while22 Field Hospital and Ministry of Defence Hospital Unit<br />

(Frimley Park) are scheduled to move to Keogh Barracks starting next year, following further<br />

refurbishment and new buildings.<br />

Over £30 million of remaining major works will follow with procurement starting shortly to<br />

provide a new Sergeants’ Mess, stores, vehicle workshops and an armoury.<br />

The redevelopment of Keogh Barracks is part of the Army Basing Programme (ABP), which is<br />

providing the facilities the Army needs to live, work and train in the UK as it returns from<br />

Germany, relocates bases across the UK and restructures under Army 2020. This year more<br />

than 5,000 Service personnel have returned to the UK from Germany and 1,800 have relocated<br />

within the UK as part of the programme.<br />

Addressing poor air<br />

quality<br />

Research shows that modern airtight<br />

homes are more likely to<br />

suffer from poor indoor air quality<br />

and leads to change in Scottish building<br />

regulations.<br />

After years of research into poor indoor air<br />

quality in modern homes, a team of British<br />

architects have been recognized by the<br />

Chartered Institute of Building Services<br />

Engineers. Dr Stirling Howieson, University<br />

of Strathclyde, Dr Tim Sharpe, Mackintosh<br />

Environmental Architecture Research Unit<br />

and Paul Farren, ASSIST Design Ltd. were<br />

presented with the Napier Shaw Bronze<br />

Medal award on 9th October 2015 at the<br />

annual CIBSE President’s Award Dinner for<br />

their 2014 research paper, “Build Tight,<br />

Ventilating Right?” which demonstrated<br />

that standard air tightness levels within<br />

houses constructed to current regulations<br />

are likely to result in poor indoor air<br />

quality.<br />

Further research by the team, undertaken<br />

on behalf of the Scottish government, has<br />

led to a change in the Building Standards.<br />

From October 2015 all new homes in<br />

Scotland are to be fitted with bedroom<br />

CO2 monitors.<br />

Finalists announced<br />

for 2015 Offsite<br />

Construction Awards<br />

The inaugural Offsite Awards has seen<br />

fierce competition with a flood of<br />

high-calibre entries competing to be<br />

crowned as industry leaders of the offsite<br />

construction market.<br />

With nearly 150 entries across 12<br />

categories, the awards have been packed<br />

full of outstanding, ground breaking<br />

projects, products and people. The winners<br />

will be announced at a relaxed drinks and<br />

nibbles reception, to be staged at the<br />

Inmarsat Conference Centre in London on<br />

December first.<br />

The awards ceremony will attract over 300<br />

national business leaders and high profile<br />

decision makers from the offsite<br />

construction industry, plus architects,<br />

engineers, contractors and clients,<br />

providing a significant platform for<br />

targeting the offsite industry. The event will<br />

also present the ideal opportunity for<br />

professionals to maximize industry<br />

exposure and penetrate this innovative<br />

market.<br />

Each of the judges has assessed four of the<br />

12 categories on a strict and confidential<br />

marking system to establish the award<br />

category winners, highly commended and<br />

shortlisted entries.<br />

Offsite construction sector raising the bar on<br />

skills<br />

Employers in the offsite construction sector have signaled the importance of<br />

working together to recognize and address skills gaps if they are to capitalize on<br />

the growth opportunities available to the sector.<br />

The employers, including Skanska and Laing O’Rourke, have led five skills projects cofunded<br />

by the UK Commission for Employment and Skills’ (UKCES) Futures Programme.<br />

The projects piloted different approaches to improve sector collaboration and provide<br />

better training opportunities for both new and existing workers.<br />

In October, UKCES published findings based on the delivery of these projects which<br />

demonstrate:<br />

• The clear need for industry leadership to capitalize on the opportunities afforded by the<br />

industrialization of the sector.<br />

• Employers can raise the bar on skills in sectors, regions and supply chains, by working<br />

with each other, their employees, universities and professional associations.<br />

• Collaboration has been shown to be vital to building the skills needed for growth and the<br />

topic of skills has brought competing businesses together to address their common<br />

need.<br />

• Competitors can become collaborators where there is a commonly experienced<br />

challenge which can be better tackled together, and where there is a foundation of<br />

strong individual or group relationships which can be built upon.<br />

• The breadth and depth of skill gaps were sometimes greater than project teams first<br />

realized, but in recognizing the gaps, corrective action could be taken. The report shows<br />

that it is crucial for employers in the sector to take responsibility and recognize these<br />

gaps otherwise they risk being left behind.<br />

• Educators and businesses must work more closely together to ensure educational<br />

institutions and professionals keep up with technological advancements and ensure<br />

innovation can be capitalized upon.<br />

Revolutionizing green building technology<br />

Smartphones, thermal imaging technology anad cloud computing could boost Europe’s<br />

ability to meet energy efficiency goals<br />

A €6.4 million project to revolutionize the way our industry delivers green buildings was<br />

launched in London on the 17th November. 20 UK and European partners will create new<br />

smart tools and cloud computing platforms to transform the energy efficiency and<br />

construction industries. Funded by our contributions to the Horizon 2020 programme – an<br />

€80 billion research and innovation fund – the ‘Built to Specifications’ (Built2Spec) project will<br />

use new technology to radically improve the design, installation and testing of building<br />

standards and retrofit. Together, the measures will help the built environment hit 2050<br />

carbon targets and reduce fuel poverty.<br />

CPA’s Skills Report ways to formalize<br />

construction training<br />

Manufacturers and distributors of construction products run thousands of training<br />

programmes for the builders and tradespeople who install their products. An<br />

opportunity exists to put that training on a formal footing with nationally recognized<br />

qualifications, a<strong>cc</strong>ording to a report from the Construction Products Association.<br />

‘Skills Report 2015’ – produced with support from the Construction Industry Training Board<br />

(CITB) – is the third in a series of projects that the CPA is contributing to understand skills and<br />

materials constraints facing the industry. It maps the large number of training activities which<br />

association members currently run, particularly for ‘product-users’, and recommends a new<br />

process to align that training to recognized qualifications.<br />

Loading up! Metsec takes student living to the next<br />

level<br />

Light gauge structural steel specialist voestalpine<br />

Metsec plc has supported the renovation of Portland<br />

House, Exeter, a 1960s concrete framed building -<br />

part of a £17m luxury student a<strong>cc</strong>ommodation<br />

scheme for developer Select Property Group, under<br />

its Vita Student brand. Originally a four-storey<br />

structure, Portland House has been converted into<br />

seven-storey student a<strong>cc</strong>ommodation, totalling 161<br />

high-end flats with the use of Metsec’s load bearing<br />

steel frame structure (SFS) system.<br />

Metsec’s load bearing SFS system enabled three additional storeys to be added to the original<br />

concrete building without impacting the structure, due to its lightweight design. These<br />

structures are stick built on site, which ensures maximum flexibility of the structure, and there<br />

was no need for the use of cranes to build the SFS. With land expensive and scarce in city<br />

centres, building upwards on existing structures is key to solving the shortage issue, and SFS<br />

has proved to be the most cost- and resource-effective way to do this.<br />

As a start of the investment and long<br />

term commitment to Natural Slate, the<br />

group has decided to dedicate a<br />

specific person to this product group,<br />

Sales Director, Rob Wallace. Rob has 18<br />

years of experience in growing<br />

Cembrit’s business from its Welsh<br />

depot in Llandow, achieved through<br />

unbeatable customer service.<br />

“This marks the beginning of a new<br />

phase in Cembrit’s commitment to<br />

natural slate,” said Marketing Manager<br />

Offsite given wings<br />

Juliet Woodcock looks at a new concept surrounding modern methods of construction<br />

It has long been a<strong>cc</strong>epted that<br />

manufacturing construction elements in<br />

the factory environment is safer, ensures<br />

higher quality end products with reduced<br />

wastage and can help meet tight deadlines, as<br />

well as getting around the problem of the<br />

skills shortage we are still experiencing postrecession.<br />

But, as with every good idea, there is always<br />

someone who will take it one step further: on a<br />

large building contract, why not take the<br />

factory to the site? Indeed, a project funded<br />

through the Technology Strategy Board’s Low<br />

Impact Buildings Innovation Platform has<br />

undertaken a fundamental rethink of building<br />

processes, developing ‘flying factories.’<br />

Led by Skanska, the project involves partners<br />

from ModCell, Exelin *the South West<br />

Manufacturing Advisory Service), the University<br />

of Reading, and the Building Research<br />

Establishment. Together they have developed<br />

the system of ‘near-site’ manufacture using<br />

modern flying factories.<br />

To develop the technique and secure funding,<br />

Skanska’s innovation team put together a<br />

research consortium of external organizations.<br />

Inspiration was taken from the offsite<br />

fabrication of May Park School in Bristol.<br />

Combined with virtual-reality-enabled supply<br />

chain management and process improvement,<br />

the system can provide a 28 per cent reduction<br />

in cost per square metre and 30 per cent<br />

shorter programmes, delivering higher quality<br />

and a more predictable build.<br />

“With flying factories you are<br />

not tied into big overheads or<br />

high transport costs; and you<br />

are adapting the factory to<br />

exactly fit your needs at the<br />

time, so the concept is opening<br />

up the potential for a massive<br />

increase in the level of offsite<br />

fabrication across the country”<br />

Sam Stacey,<br />

Head of Innovation at Skanska<br />

The concept was used to assemble wall panels<br />

for Glenfrome School in Bristol, enabling a<br />

building extension to be completed in just six<br />

weeks during the summer holiday.<br />

It was then su<strong>cc</strong>essfully applied to the SRW<br />

engineering services project for the Battersea<br />

Power Station Development Company phase<br />

one, where 550 ‘utility cupboards’ have been<br />

created for residential use. Significant cost and<br />

programme savings have been recorded for<br />

both projects; for the Battersea scheme, cost<br />

and time savings of 44 and 65 per cent were<br />

achieved.<br />

If the Government is to reach its 2025<br />

construction targets of 33 per cent reduction in<br />

building costs and 50 per cent faster delivery,<br />

plus 50 per cent lower emissions, then near site<br />

factories could offer a significant part of the<br />

solution.<br />

Manufacturing components offsite, but close to<br />

the location for erection or installation helps to<br />

deliver many efficiencies:<br />

• Faster onsite installation<br />

• Minimal quality defects and associated waste<br />

• Optimized transport solutions to reduce costs<br />

• Overall reduction in operational and embodied<br />

carbon<br />

• Safer working environments for personnel<br />

• More likely to meet programme deliverables<br />

and reduce commercial risk<br />

• Avoiding the problems of poor weather<br />

Speaking exclusively to <strong>MMC</strong> Magazine, Sam<br />

Stacey, Head of Innovation for Skanska<br />

commented: “The concept of flying factories is<br />

that they are temporary and flexible so ideally<br />

they need to be located within 25 miles of the<br />

site where buildings will be located: so we will<br />

be looking at rented warehouse space or<br />

possibly temporary hire structures erected on<br />

hard-standing. Good transport connections with<br />

the final site are essential.<br />

Skanska has fabricated these large utility cupboards for an apartment project in Battersea,<br />

pre-fitted with all the M&E equipment including MVHR<br />

“It will also mean taking on labour on a<br />

temporary basis which, although it has not<br />

proved a problem to date, does require us to<br />

get people up to speed quickly in order to<br />

maximize the benefits. The approach then is to<br />

simplify the processes as far as possible,<br />

possibly taking steps out of the assembly<br />

process; and as much as possible making it like<br />

assembling a piece of furniture.<br />

“At present the design supply chain is not well<br />

established to facilitate this type of working,<br />

but we will look to use templates where we can.<br />

The advent of Building Information Modelling<br />

(BIM) also offers a good basis for progress and I<br />

believe we can benefit with 3-D modelling, as<br />

well as what we term ‘virtual rehearsals’. There<br />

is a degree to which we will have to be<br />

responsive to each type of assembly we have to<br />

work with. ”<br />

Apparently Sam Stacey’s team includes<br />

software specialists adept at working with<br />

virtual reality and they have already been<br />

experimenting with the Oculus type gaming<br />

headsets: making it possible to walk through<br />

some of the building prototypes currently being<br />

planned. This type of advancement could soon<br />

put the technology underpinning flying<br />

factories on an even footing with the<br />

automotive and other high tech industries.<br />

“I think this type of technology will be<br />

enormously helpful for those involved,”<br />

continued Sam Stacey, “To experience what we<br />

are proposing to build, including the<br />

construction sequence, and identifying any<br />

gaps in the design, or something we can<br />

improve in the process. It will be applicable to<br />

anything that can be produced as a pod:<br />

kitchens, bathrooms or the utility cupboards we<br />

have been producing for a residential<br />

development in Battersea – packed with the<br />

M&E equipment.<br />

“With flying factories you are not tied into big<br />

overheads or high transport costs; and you are<br />

adapting the factory to exactly fit your needs at<br />

the time, so the concept is opening up the<br />

potential for a massive increase in the level of<br />

offsite fabrication across the country.<br />

“ It is also a good environment to ‘tag and<br />

track’ all the components with RFID (Radio<br />

Frequency IDentity) tags which then facilitate<br />

quality checks and carry out condition<br />

monitoring to support condition based<br />

maintenance of moving and rotating<br />

machinery; particularly pumps.”<br />

Gary Peters from Exelin, reviewing the<br />

field tools for the tag and track solution<br />

Back in July, Skanska was additionally awarded<br />

£700,000 to develop construction robots, to be<br />

used to carry out several tasks, including<br />

cutting, drilling and fixing on site. The funding<br />

was awarded by Innovate UK and the<br />

Engineering and Physical Sciences Research<br />

Council (EPSRC) as part of their collaborative<br />

R&D programme; and it is expected that these<br />

robots will also be used in flying factories to<br />

further speed up the build process.<br />

Iain Gray, Chief Executive of the Technology<br />

Strategy Board, said of the flying factory<br />

notion: “The work we are funding will<br />

encourage the UK construction industry to<br />

undertake a fundamental rethink of current<br />

ways of working and enable businesses to<br />

explore potential commercial opportunities<br />

created by novel design, procurement and<br />

construction processes.”<br />

While capital investments are greatly reduced<br />

by rented space for flying factories, the pilots<br />

did reveal that the break in continuity of<br />

production could be an issue; which automation<br />

might overcome. Other lessons learned were<br />

that there needs to be an increased control<br />

over the start-up phase regarding decision<br />

making, early decisions and involvement of<br />

expertise, as well as increased control over the<br />

design and production process.<br />

New unitised curtain walling<br />

launched by Kawneer<br />

Glazing systems specialist Kawneer expands its curtain wall portfolio.<br />

Today’s safety-conscious and fast-paced<br />

construction schedules demand high<br />

performance, fast installation, simplified<br />

fabrication, superior performance and design<br />

flexibility.<br />

The DTI document “Manufacturing for the<br />

future” has long pressured the industry to<br />

increase awareness of off-site construction and<br />

build on the knowledge available across Europe<br />

and America.<br />

It clearly highlights that off-site construction<br />

should be considered for hotels, hospitals,<br />

schools and supermarkets. But in reality,<br />

because systems such as unitised curtain walling<br />

do not require scaffolding, they are suitable for<br />

any site where a<strong>cc</strong>ess is difficult or restricted - in<br />

itself a growing phenomenon, with 70% of newbuild<br />

now on brownfield sites.<br />

With curtain walling being one of the most eyecatching<br />

elements of a façade, its evolution from<br />

the traditional stick system to a unitised one is<br />

perhaps one of the most obvious signs that the<br />

Government’s drive off-site is being embraced.<br />

The factory production of unitised curtain<br />

walling from leading UK architectural aluminium<br />

systems supplier Kawneer gives predictability of<br />

time and cost, guarantees quality that reduces<br />

problems, delays and snagging on site, and<br />

avoids delays caused by adverse weather<br />

conditions.<br />

On-site time can also be reduced substantially,<br />

saving labour costs and minimising local effects<br />

such as noise, dust and traffic congestion. Where<br />

there is a shortage of skilled site labour, off-site<br />

manufacture ensures high build quality is<br />

maintained.<br />

Now Kawneer, which has 50 years of unitised<br />

curtain walling expertise, has enhanced its<br />

extensive curtain wall portfolio with the launch<br />

of a new fast-track dry-glazed unitised system.<br />

The AA ® 265 incorporates a three-chamber<br />

system and overlapping gasket design for<br />

optimum weather tightness. Its dry-glazed<br />

assembly combined with the use of the same<br />

extrusion to all four sides provides both ease of<br />

fabrication and the opportunity for effective bar<br />

optimisation.<br />

In addition, if a<strong>cc</strong>ess during installation is<br />

limited, the AA ® 265 system can be installed<br />

under restrictive working conditions, with the<br />

building remaining o<strong>cc</strong>upied.<br />

The optimum weathering is achieved by zonedrained<br />

pressure equalisation, with the glazing<br />

providing a positive weather seal for high<br />

performance. The system also features an<br />

exclusive high-performance thermal break.<br />

Its slim 65mm sightlines, picture-frame style<br />

capping, integral vent option and dual-finish<br />

gives specifiers a wide choice of options to<br />

create individual and exciting building facades as<br />

the AA ® 265 can a<strong>cc</strong>ommodate spandrel infill<br />

panels of glass, stone and metal up to 50mm.<br />

Adaptable to any new construction project from<br />

two storeys upwards, the AA ® 265 system has<br />

been exclusively designed and developed by<br />

Kawneer, with installation contracts undertaken<br />

in collaboration with its network of authorised<br />

dealers.<br />

Kawneer’s unitised range of curtain walling also<br />

includes the AA ® 201 unitised system which<br />

suites with the company’s AA ® 130 Brise Soleil,<br />

has 63.5mm sightlines and can a<strong>cc</strong>ommodate<br />

infill panels up to 32mm.<br />

As well as many of the features of its sister<br />

AA ® 265 system, the AA ® 201 is available with<br />

fully-capped and SSG (Structurally Silicone<br />

Glazed) options in addition to a horizontal cap<br />

with vertical silicone joint, vertical cap with<br />

horizontal silicone joint and a range of mullion,<br />

transoms and face cap options with 63.5mm<br />

Timber frame construction & the<br />

risk of disproportionate collapse<br />

A £1.4 million five-storey development of some 1,700 square metres, a<strong>cc</strong>ommodating 23 individual apartments,<br />

Aubrey Street in Herefordshire was a substantial project for timber frame specialists Taylor Lane.<br />

Versaliner liner Sheets<br />

Taylor Lane had been engaged by the<br />

main contractor Speller Metcalfe, an<br />

award-winning sustainable construction<br />

company, with expertise in BREEAM,<br />

Passivehaus and the Code for Sustainable<br />

Homes.<br />

The Project<br />

The development, for client Matches Housing<br />

Association, was to be constructed in close<br />

proximity to several existing properties on<br />

three sides. As is often the case with<br />

developments where space and a<strong>cc</strong>ess are<br />

restricted, off-site construction methods<br />

present an attractive solution. Taylor Lane<br />

specialise in manufacturing structural grade<br />

C16 timber frame panels in a quality-controlled<br />

factory environment.<br />

Prior to Aubrey Street, Taylor Lane’s timber<br />

frame panels incorporated an external<br />

sheathing layer comprising, typically, either<br />

OSB or plywood, depending on the application.<br />

Indeed, the specification for Aubrey Street had<br />

specified just these kinds of materials. Taylor<br />

Lane decided that something more was needed.<br />

The Challenge<br />

The close proximity of the site to other<br />

buildings and the risk of disproportionate<br />

collapse meant that the consequences of<br />

14<br />

a<strong>cc</strong>idental fire or even a possible arson attack<br />

had to be taken very seriously. This is a<br />

particular hazard faced by timber frame<br />

construction projects. In fact, the Structural<br />

Timber Association has launched several<br />

initiatives to combat this phenomenon,<br />

including detailed guidance.<br />

A<strong>cc</strong>ording to the STA guidance, “All buildings<br />

should have appropriate fire protection<br />

designed and built-in as early as possible and<br />

maintained throughout the entire construction<br />

phase… For small or low-risk sites, the general<br />

good housekeeping and standard approach<br />

may be more appropriate… For other sites the<br />

sub-division of the frame by fire-resisting<br />

barriers must be considered as part of the<br />

strategy for minimising fire spread risk during<br />

construction.<br />

The solution<br />

Aubrey Street certainly didn’t fall into the<br />

“small or low-risk” category. Consequently,<br />

Taylor Lane opted to use Euroform’s Versaliner<br />

instead of the specified OSB.<br />

Versaliner is an A1 non-combustible Magnesium<br />

Oxide sheathing board with excellent tensile,<br />

compression and breaking strengths, and high<br />

resistance to impact, moisture and insect<br />

attack. Excellent racking resistance means it is<br />

particularly suited to timber frame applications,<br />

offering additional stability. The fact that<br />

Versaliner is a “score and snap” materials<br />

means it can be fabricated on-site without the<br />

need for additional cutting equipment or can be<br />

seamlessly incorporated into the streamlined<br />

processes of off-site, factory-based<br />

construction.<br />

Taylor Lane worked closely with Euroform’s<br />

technical team, taking advantage of their<br />

expertise and experience in the complex area<br />

of passive fire protection, to ensure Versaliner<br />

was the appropriate product for this particular<br />

application.<br />

Duly satisfied that all their criteria had been<br />

met and all their concerns addressed, Taylor<br />

Lane began incorporating Versaliner into their<br />

timber frame panels as part of their off-site<br />

construction process.<br />

A spokesperson for Taylor Lane said,<br />

“Versaliner enabled us to safely build on a site<br />

where fire risk was a significant factor. Without<br />

it, we’d have struggled to proceed. We’re more<br />

than happy with the product, it’s very<br />

competitive pricing and ready availability.”<br />

Can rooftop extensions be a solution to the housing crisis?<br />

The shortage of suitable land for housing, particularly in London,<br />

is recognised as one of the reasons why we are continually<br />

hearing about this nation’s housing crisis. During the 19th<br />

Century land was also at a premium and the advancement of<br />

engineering developments, including the first passenger lifts, made it<br />

possible to build habitable high rise a<strong>cc</strong>ommodation. This method of<br />

building continued to grow in popularity with many UK cities seeing a<br />

large number of high rise blocks erupting from the 1930s-1970s. Many<br />

of these buildings were over-engineered to such an extent that it is still<br />

possible for the structure and foundations to support up to 50% more<br />

floors than originally constructed. With the advances in engineering<br />

technologies in <strong>MMC</strong> this spare structural capacity can be exploited to<br />

provide a solution to housing needs without the need to use more land.<br />

Social issues and transport links aside, the first step in determining if a<br />

particular scheme is suitable is to identify which buildings are likely to<br />

gain planning approval and have the necessary structural engineering.<br />

If the structural report confirms there is sufficient integrity within the<br />

structure the next step is to identify which system is most appropriate<br />

for the intended purpose. Modular light gauge steel offers significant<br />

benefits and will fit many common situations.<br />

The solution on offer from Premier Modular Limited provides a cost<br />

effective, high quality system which will be constructed in an ISO9001<br />

and ISO14001 factory environment. The volumetric rooftop extension is<br />

then transported to site and installed with significantly reduced time on<br />

site and minimal disruption for existing residents. The Premier Modular<br />

system allows the roof to be factory fitted with the option of a vaulted<br />

ceiling. The end result is a high quality living a<strong>cc</strong>ommodation built to<br />

all relevant standards including Life Time Homes which can be<br />

mortgaged, complete with a 10 year insurance backed warranty through<br />

Checkmate.<br />

STEICO – natural products for<br />

healthy buildings<br />

STEICO products are innovative building materials that offer long-term performance, increase the comfort of living<br />

and help to visibly increase the energy efficiency in buildings. STEICO products are especially economical and<br />

environmentally-friendly as they are produced from sustainable resources.<br />

STEICO Joist in roof application<br />

STEICO Special and STEICO<br />

Flex in a roof refurbishment<br />

< STEICO Joist close up<br />

Whether for engineered timber<br />

elements or insulation materials,<br />

roofing boards or wall panels,<br />

STEICO offers a suitable product for each<br />

building application. In the UK market STEICO<br />

is best known for its market leading I Joist<br />

which many of the major builders use in their<br />

developments. Increasingly smaller builders<br />

and developers are also changing from solid<br />

timber to I joists due to the performance, light<br />

weight and ease of a<strong>cc</strong>ess for service runs.<br />

Complementing STEICO joists a brand new<br />

state of the art 80,000 cbm Laminated Veneer<br />

Lumber plant has recently been commissioned<br />

and started production in September 2015. This<br />

makes STEICO unique in that it is the only<br />

European company to manufacture all the<br />

components of the I Joist. This gives<br />

distributors and end users a guaranteed robust<br />

supply channel with maximum control of costs<br />

going forward.<br />

STEICO is also the UK market leader in thin<br />

wood fibre underlay boards for use under<br />

laminate and wood flooring systems and is the<br />

product of choice for many professional floor<br />

fixers. Many of the own branded wood fibre<br />

underlay products in the major DIY chains are<br />

manufactured by STEICO. Other products<br />

showing significant growth in the UK are<br />

18<br />

boards for sarking applications, a partnership<br />

with Lime Green Products using Protect<br />

breathable render carrying board, and Flexible<br />

wood fibre batts in timber frame new build,<br />

refurbishment and commercial projects.<br />

All the insulation products benefit from the<br />

inherent properties of the natural materials<br />

that they are made from. The natural fibre<br />

insulation materials, for example, are<br />

distinctive as they offer diffusion qualities that<br />

contribute to a healthy indoor climate. The<br />

joists, used as construction elements, also<br />

follow nature’s examples and combine lean<br />

design and lightweight properties with a high<br />

load capacity. All products are easy to handle,<br />

non-allergenic and durable, real future proof<br />

building materials.<br />

Warm in winter – Cool in summer<br />

Worldwide more energy is used for cooling<br />

buildings than for heating them. Based on this<br />

it is reasonable to appraise the efficiency of an<br />

insulation product not only for its ability to<br />

prevent energy loss in winter months but also<br />

for its protection from heat ingress during the<br />

summer months. STEICO products provide a<br />

low thermal conductivity combined with a high<br />

heat storage capacity. Due to these special<br />

factors a comfortable cool environment in<br />

summer and a comfortable warm environment<br />

in winter can be achieved.<br />

Pro Environment – Pro Living<br />

While choosing materials and production<br />

methods, STEICO, as a producer of wood based<br />

ecological building materials, pays particular<br />

attention to the environment and healthy living.<br />

There is a clear commitment to meeting the<br />

needs of the present without compromising the<br />

needs of future generations with products that<br />

perform in both function and quality. The entire<br />

range of STEICO Insulation products are<br />

certified by FSC®, ensuring sustainable<br />

traceability of the raw wood fibre materials. In<br />

addition, the insulation boards also carry the<br />

seal of approval from the Passivhaus Institute<br />

and the Institute for Building Biology (IBR),<br />

Rosenheim, both of whom acknowledge the<br />

high energy efficiency performance gained by<br />

using STEICO products in many building<br />

applications.<br />

STEICO has its own sales and marketing office<br />

in the UK and its experienced staff offers<br />

technical advice on product use to supply chain<br />

partners, house builders, developers and<br />

Architects. Information can also be found on<br />

the company website.<br />

Technical Editor, Bruce Meechan hears from Ged Ferris of Cembrit about the wide selection of board products the<br />

manufacturer can offer for internal and external construction applications.<br />

The term one-stop-shop may be over<br />

used in the UK building products supply<br />

chain, but the range of boards offered<br />

by long-established manufacturer, Cembrit<br />

can provide specifiers with solutions to every<br />

sort of challenge from interior refurbishment<br />

and the creation of wet rooms within social<br />

housing units, to some of the most daunting<br />

logistical demands faced by burgeoning offsite<br />

or <strong>MMC</strong> sector.<br />

.The majority of the board options offer not just<br />

excellent physical characteristics, but a strong<br />

lineage and a long track record of service, both<br />

here and on the Continent.<br />

The SP board offers a very rapid means of<br />

effectively tanking a room<br />

As UK Marketing Manager, Ged Ferris,<br />

commented during our interview: “We have the<br />

product range to facilitate the needs of<br />

everyone from offsite system fabricators to<br />

refurbishment specialists and the growing selfbuild<br />

market.<br />

Not just a Five-star range, but a range with five<br />

main stars and many product variations:<br />

Cembrit’s flat boards encompass all the key<br />

performance parameters including moisture<br />

resistance, fire resistance and structural<br />

strength, as well as providing a versatile<br />

substrate for commonly used finishes.<br />

THE RANGE General purpose and specialist<br />

requirements solved by Cembrit’s boards<br />

The product within the range which has shown<br />

the most rapid growth across the market is PB:<br />

a versatile tile backer or render backer board,<br />

mainly being used for the refurbishment of<br />

bathrooms, it is popular due to its low weight<br />

and ease of cutting which facilitates<br />

installation, and the robust long term<br />

performance. Cembrit has developed a version<br />

called Flex which can be fixed down to radii of<br />

just 150 mm. Both conventional PB and Flex<br />

features polystyrene spherules and an edge<br />

reinforcement detail that uses a special fabric<br />

allowing butt jointing and fixings close to edges<br />

This Walsall project shows a<br />

typical sheathing application<br />

for Cempanel before final<br />

cladding is installed<br />

for maximum rigidity. Flex installations might<br />

then form a column casing that would be<br />

rendered over or covered with a small format<br />

mosaic.<br />

Where social housing providers are seeking to<br />

fit out full wet rooms for those who might need<br />

assistance with personal care, then there is also<br />

a Special Performance board which was<br />

originally developed for use in places like<br />

swimming pools.<br />

The biggest seller still, though in terms of<br />

volume is Cempanel which is primarily specified<br />

for dry-lining and sheathing: the internal skin to<br />

a rainscreen cladding build up. Depending on<br />

dimensions, Cempanel can also take racking<br />

loads: being produced in thicknesses of 8, 10, 12<br />

and 16 mm. It is also often used as a render<br />

carrier in exterior applications.<br />

The Cembrit range of high performance board products is ideally suited to use<br />

by the offsite sector as well as for refurbishment and other applications<br />

The FR board can provide up to 120 minutes of<br />

fire resistance and is widely specified for soffits<br />

in corridors, lift lobbies and other communal<br />

“We see our board range as<br />

being of particular value to<br />

manufacturers of modules,<br />

pods, timber frame panel<br />

systems and other<br />

prefabricated solutions.<br />

They could even form the<br />

face to SIPs (Structural<br />

Insulated Panel) systems.”<br />

Ged Ferris, UK Marketing Manager, Cembrit<br />

Fire resistance approval testing on FR board<br />

areas to buildings where the consideration of<br />

escape routes and combating the surface<br />

spread of flame are essential.<br />

Ged Ferris added: “We see our board range as<br />

being of particular value to manufacturers of<br />

modules, pods, timber frame panel systems and<br />

other prefabricated solutions. They could even<br />

form the face to SIPs (Structural Insulated<br />

Panel) systems.<br />

“As well as the merchant stockist, clients can<br />

also purchase through ‘optimizers’ – board<br />

cutting specialists who supply the exact sizes<br />

they need to make our standard product<br />

PB Flex used as a tile backing<br />

coordinate with elevation widths, window<br />

openings and things like flues or other service<br />

penetrations. It will also be a real advantage to<br />

customers that such a comprehensive selection<br />

is available from a single source.”<br />

Responding to market demand, Cembrit is also<br />

making its cladding boards available as BIM<br />

objects in partnership with its Scandinavian<br />

parent company. These can be viewed via the<br />

company’s website at www.cembrit.co.uk or by<br />

Acoustic Fire &<br />

Thermal ><br />

Simple airtightness<br />

solution is a BBA first<br />

Specifiers and architects looking for a<br />

straightforward but healthy and effective<br />

air tightness solution for buildings need<br />

look no further than Wraptite-SA.<br />

The abilities of this single-component,<br />

externally applied air barrier from the A.<br />

Proctor Group have now been officially<br />

recognised by the BBA following<br />

comprehensive assessment at its<br />

laboratory in Watford. The product makes<br />

a significant contribution to a building’s<br />

thermal performance by preventing<br />

lateral air movement, but also helps<br />

maintain a healthy living environment<br />

and structure thanks to its high vapour<br />

permeability rating (Sd 0.039).<br />

The self-adhering membrane fully bonds<br />

to virtually any substrate, requiring no<br />

mechanical attachment, seals or tapes to<br />

suppress air leakage around junctions or<br />

penetrations.<br />

Skanska specifies Cygnus for new city building<br />

The Monument Building in the heart of the City of London is one of the current projects to<br />

use Bull Products’ latest Cygnus wireless alarm system during construction works. Standing<br />

adjacent to The Monument, which marks the origin of the Great Fire of London, the 88,000sq<br />

ft office a<strong>cc</strong>ommodation is split over ten floors with terraces at several levels.<br />

Skanska has been using the Bull Products system since<br />

construction started last year, specifying some 26 units.<br />

Intended purely for use on construction sites, the CE marked<br />

Cygnus system has been specifically designed for use in dense<br />

concrete and steel structured buildings and areas where there<br />

are many other radio frequencies in operation.<br />

The Cygnus alarm system can link as many as <strong>48</strong>0 alarm and<br />

detector units in different zones on a construction site, and<br />

individual units can be fire alarm call points, first aid alerts,<br />

combined call points and first aid alerts, smoke detectors, or<br />

heat detectors.<br />

Knauf Facades simplifies school construction<br />

Timely technical support reinforced with on-site<br />

inspections led to CRT Construction to choose SFS<br />

systems from Knauf Facades when engaged by Wates<br />

Construction in the project to build the £4.7 million<br />

Garston Manor SEN school in Watford.<br />

The single storey 3,000m2 building provides 120<br />

places for students aged 11 to 16 years and features<br />

flexible teaching spaces, food technology, art, drama<br />

and science areas, specialist sensory rooms and<br />

pastoral care units.<br />

All Knauf Exterior Wall Systems have been fully designed and tested for their structural,<br />

thermal, fire and acoustic performance in collaboration with UKAS laboratories and industry<br />

leading consultants such as the Steel Construction Institute (SCI). Fire safety is operational<br />

from the start, allowing for high levels of fire protection during construction, as well as once<br />

the project is complete.<br />

www.knauf.co.uk<br />

Wraptite-SA has received BBA<br />

certification (no. 15/5274) for use in both<br />

roofs and in walls behind the rain screen<br />

cladding making it an ideal choice for<br />

commercial projects with large<br />

uninterrupted facades.<br />

Key construction benefits:<br />

• Air tightness - as well as wind<br />

resistance during construction<br />

• Water resistance - providing<br />

temporary protection for the<br />

building fabric during construction<br />

• Breathability - allows vapour to<br />

escape reducing condensation for<br />

users and structure<br />

• One-piece solution – requires no<br />

tapes<br />

• Self-adhering- reduces mechanical<br />

fixings of the membrane and<br />

ensures less risk of water/wind<br />

without limiting vapour<br />

permeability<br />

Eurocell helps transform market into Nottingham’s<br />

Creative Quarter<br />

Technical support from Eurocell has contributed to the<br />

£3.85 million redevelopment of Sneinton Market that<br />

planners believe will transform it into the Nottingham’s<br />

own Covent Garden.<br />

Wates was appointed as main contractor to refurbish<br />

three of the five 'avenues' at Sneinton Market, funded<br />

through a £2.44m European Regional Development<br />

Fund (ERDF) grant and a further £1.45m from the City<br />

Council. And Wates selected Derbyshire Floorcraft to<br />

refurbish the 8 x 80m long lean-to roofs that are an integral part of the market’s particular<br />

appearance.<br />

“Eurocell provided outstanding service,” says Darren Scarborough of Derbyshire Floorcraft. “It<br />

modified one of its conservatory roof products and produced it in a bespoke colour, anthracite,<br />

so it was in keeping with the heritage nature of the site and sent its architect and design team<br />

to site to make sure it all fitted properly. The result is a design that matches the original<br />

Victorian design but delivers a 21st century performance.”<br />

Totally drained...<br />

Range of products changing approach to modern methods of residential drainage<br />

“The systems have been specifically designed<br />

to provide flexible solutions to problems that<br />

face those building residential property every<br />

day. They meet the best-practice requirements<br />

of all current SuDS guidance and legislation.”<br />

Providing a more natural approach to managing<br />

rainfall, Skeletank is a Surface water drainage<br />

system (SuDS) that can deliver provide both<br />

infiltration and attenuation. Skeletank solutions<br />

are suitable for pervious, impervious and softlandscaped<br />

surfaces making them incredibility<br />

flexible in use.<br />

Designed to manage surface water run-off<br />

within the grounds of each individual property,<br />

the system can return the water to the ground<br />

and/or store the water before releasing it in a<br />

controlled manner to the mains sewer network,<br />

or adjacent watercourses.<br />

Arange of products is now proving<br />

popular with construction companies<br />

looking for innovative and modern<br />

methods following its launch earlier this year.<br />

Skeletank is now set to take the UK house<br />

construction market by storm, offering a<br />

solution to addressing the issues faced by<br />

residential builders when designing and<br />

installing surface water drainage systems.<br />

...Skeletank systems offer<br />

ground breaking design<br />

benefits to residential<br />

drainage schemes,<br />

gathering rainwater at<br />

source and allowing its<br />

controlled release...<br />

Providing innovative sustainable drainage<br />

systems (SuDS) designed specifically for<br />

residential properties, Skeletank is only<br />

available from Hydro Water Management<br />

Solutions (Hydro WMS) and is the first modular<br />

systems of its type in the UK.<br />

Adhering to the management train laid out in<br />

CIRIA C697, Skeletank systems bring with them<br />

26<br />

a host of benefits for residential developers,<br />

social housing companies, local authorities and<br />

construction companies.<br />

Potential benefits include releasing more land<br />

for development; substantial reduction in<br />

upfront costs of adoptable networks; improved<br />

cash-flow for developers; CDM and Health &<br />

Safety benefits and most importantly, the<br />

reduction of flood risk.<br />

Director of Hydro WMS Brian Byrne explains<br />

further: “Skeletank systems offer ground<br />

breaking design benefits to residential drainage<br />

schemes, gathering rainwater at source and<br />

allowing its controlled release, either naturally<br />

back into the environment, or into the sewer<br />

network at a manageable rate.<br />

This modern method of managing surface<br />

water run-off at source can reduce the up-front<br />

cost of adoptable networks and provide major<br />

cash-flow benefits to developers. It may also be<br />

possible to reduce the size of<br />

open water features on site,<br />

such as ponds, thus allowing<br />

more room for more<br />

properties on the same sized<br />

site.<br />

The main components of<br />

Skeletank systems are<br />

designed to be installed at a<br />

shallow level beneath<br />

hardened surfaces with<br />

minimal cover. This also<br />

proves extremely costeffective,<br />

especially where<br />

there are ground issues such<br />

as contamination, high water<br />

tables or underlying rock layers. This reduced<br />

excavation means that the CDM benefits are<br />

huge, and staff safety is looked after, which is<br />

important in the world of construction.<br />

Brian concluded: “It is an exciting time for<br />

Skeletank as more and more home builders are<br />

having to look for innovative ways to deal with<br />

water and there are now stringent SuDS<br />

guidelines to be followed. We not only make life<br />

easy, but we offer so many other benefits, that<br />

Skeletank is poised to be a market leader used<br />

by large and small private and public<br />

developers.”<br />

Offsite construction – healthcare’s<br />

complete turnkey solution<br />

The capabilities of offsite more than match traditional build. Patient wards, theatres, A&E departments and<br />

cleanrooms can all be designed, built and delivered in just 12 weeks using modular methods of construction,<br />

reducing the need for interim short-term hire.<br />

> The extension has created six, six-bed wards and 15 single bedrooms<br />

with several link corridors to improve circulation within the hospital.<br />

For the first time, many healthcare<br />

establishments are considering offsite<br />

construction because of its costeffective<br />

nature and the efficiencies it<br />

provides.<br />

Matthew Goff, UK Operations Director at<br />

Actavo | Building Solutions – formerly known as<br />

Roan Building Solutions – explains how<br />

Business Information Modelling (BIM) has been<br />

integrated into offsite methods of construction<br />

and the benefits it provides.<br />

BIM – providing insight into the future of<br />

healthcare<br />

With many NHS trusts already in debt and the<br />

whole service facing unprecedented financial<br />

challenges, the introduction of BIM offers some<br />

hope for estates managers looking to deliver<br />

savings while enhancing quality.<br />

Actavo | Building Solutions is one of the first<br />

offsite construction companies to meet BIM<br />

Level 2 and it has been fully integrated into the<br />

business since June 2015. Instrumental in<br />

winning new business, Actavo | Building<br />

Solutions can now showcase the true benefits<br />

of offsite build as a quick, cost-effective and<br />

high-quality solution.<br />

Modular buildings can now be built to any<br />

specification – BREEAM, Passivhaus or AECB.<br />

As BIM helps extend design life, it can exploit<br />

advances in materials and improvements in<br />

sustainability and energy efficiency.<br />

than traditional build – which impacts on bed<br />

availability.<br />

Modular build is making the construction<br />

industry safer due to shorter construction and<br />

build times – just four weeks in some cases – as<br />

well as the buildings being manufactured in<br />

more quality controlled environments. These<br />

factors combine to make it easier for estate<br />

and facilities managers to plan and re-direct<br />

resources.<br />

New build case study: paediatric wing<br />

Cork University Hospital, Ireland, has added a<br />

brand new, single-storey €3.4m paediatric wing<br />

to its centre of excellence with a design and<br />

build project delivered by Actavo | Building<br />

Solutions.<br />

The extension sits on top of the ground floor of<br />

Cork University Hospital and has created six,<br />

six-bed wards and 15 single bedrooms with a<br />

total 1600m2 of additional floor space and<br />

several link corridors to improve circulation<br />

within the hospital.<br />

The Cork University Hospital extension was<br />

difficult to reach as it is located above a<br />

working ward within a courtyard and with<br />

limited road a<strong>cc</strong>ess. Even so, the new<br />

paediatric wing was completed in June 2015<br />

and took just 26 weeks to complete using<br />

modular methods of construction, meaning<br />

that 80% of the programme took place offsite.<br />

Actavo | Building Solutions also mirrored the<br />

existing external brick slip front so the<br />

extension was aesthetically-attuned with the<br />

rest of the hospital, as well as also fitting a<br />

pneumatic drug circulation system to both the<br />

new and existing building.<br />

Environmental design features included<br />

measures to support air-tightness and sound<br />

insulation.<br />

However, where offsite comes into its own is<br />

the cost-saving delivered through speed of<br />

delivery – sometimes up to 50 per cent quicker<br />

New ‘super school’ built offsite<br />

<strong>MMC</strong> Magazine looks at how the London Borough of Barking and Dagenham has embraced factory fabrication to help<br />

meet its rapidly rising need for education places.<br />

The 23,000 square metre Riverside Schools scheme is one of the largest<br />

education projects now under construction and will provide additional<br />

places for one of the fastest-growing school-age populations in the UK.<br />

Barking and Dagenham has one of the highest<br />

growth rates of school age children, driven in<br />

part by an ambitious housebuilding programme<br />

which is already under way. As a result there is<br />

the need for the primary school and SEN<br />

facilities to be delivered ahead of the rest of<br />

the campus, with these being set to open in<br />

time for the start of the next academic year in<br />

autumn 2016. The flexibility of the Yorkon<br />

offsite solution is making this not just possible,<br />

but practical - while the whole project is due for<br />

completion in spring 2017.<br />

The pressures on the UK’s education<br />

system are well documented and<br />

increasing, but the solutions far less<br />

evident. However, in East London the Yorkon<br />

Group company, Portakabin has been<br />

instrumental in helping deliver what is<br />

believed to be the largest ever offsite contract<br />

in the education sector..<br />

The Riverside Schools scheme in the London<br />

Borough of Barking and Dagenham covers<br />

23,000 square metres and stretches from<br />

nursery to age nineteen across three free<br />

schools, with the £44 million cost coming from<br />

the Education Funding Agency. Portakabin’s<br />

contract for all of the “curriculum spaces” was<br />

awarded via the council’s Thames Partnership<br />

for Learning.<br />

When complete the campus will a<strong>cc</strong>ommodate<br />

a 10-form entry secondary school, a 630-place<br />

primary school, a special educational needs<br />

(SEN) school, and a nursery. It will also offer<br />

extended provision outside school hours as well<br />

as wider use at weekends and during school<br />

holidays; to contribute to the local community.<br />

Roger Leighton is Chief Executive of<br />

Partnership Learning which will operate the<br />

three schools on the campus, and commented:<br />

“We have had a very good first-hand<br />

experience of the Portakabin Group’s offsite<br />

solutions as our schools currently o<strong>cc</strong>upy two<br />

earlier phases on a site near the planned<br />

Riverside Schools campus. We have been really<br />

impressed with the quality of the finished<br />

buildings, the speed of construction, and just<br />

how far offsite technology has now advanced.<br />

“The Portakabin Group makes good use of<br />

architectural design to the benefit of the users<br />

and to enhance the internal environment. As<br />

an example, our strong preference is for 75<br />

square metre classrooms which are<br />

significantly larger than the 56 square metre<br />

classrooms required by the Department for<br />

Education. With careful design and planning,<br />

use of a Yorkon offsite solution gives us the<br />

flexibility to achieve this and for almost the<br />

same budget – which is a very key benefit.”<br />

Speaking to <strong>MMC</strong> Magazine during the Offsite<br />

show at London’s Excel Centre, Simon Ambler.<br />

Director of the Portakabin Group said: “We<br />

have been building a very good relationship<br />

with the London Borough of Barking and<br />

Dagenham – this is our seventh project for the<br />

council. The contract demonstrates how the<br />

Yorkon building solutions can be employed to<br />

meet the urgent need for school places, and<br />

early engagement here has been important<br />

because of the borough’s desire to build to nonstandard<br />

sizes.”<br />

The group has invested in a new plant in York<br />

which feature’s Europe’s largest press for such<br />

systems, while also developing a new system<br />

that is not only flexible in terms of its space<br />

dimensions but also the way it can link to<br />

existing buildings<br />

Simon Ambler concluded: “We expect this<br />

project to change the face of off-site<br />

construction in the education sector.”<br />

Engineered solution ><br />

...with a certified performance designed to overcome<br />

skills shortages & meet building regulations<br />

Article ><br />

As widely reported, the recession caused a vast fall in the demand for bricks, resulting in many kilns ceasing to<br />

manufacture and bricklayers having to find alternative employment. As the industry emerged from the downturn,<br />

in 2014, it became clear that housebuilders were challenged by two major factors - a shortage of materials and<br />

traditional labour skills.<br />

Although many businesses grappled to<br />

find the best way forward, Alumasc<br />

Facade Systems turned this situation<br />

into an opportunity by developing a new and<br />

innovative facade technology designed<br />

specifically for the offsite structural timber<br />

sector – the Alumasc Ventilated System<br />

(AVS).<br />

AVS meets all UK ventilation standards for<br />

timber framed buildings and offers an<br />

industry-leading A2 Fire Performance Rating,<br />

together with the highest levels of impact<br />

resistance and is suited to all exposure levels.<br />

AVS complies with the requirements of both<br />

the NHBC and TRADA, namely the need for<br />

ventilation for structural timber construction,<br />

with a minimum of 15mm ventilated cavity for<br />

NHBC and 25mm for TRADA.<br />

The system a<strong>cc</strong>ommodates a range of cavity<br />

depths - the free-flowing system ensures that<br />

the substrate remains continuously ventilated<br />

and prevents any moisture tracking back to<br />

the primary structure, removing condensation<br />

– providing a protective facade.<br />

Offering an alternative method of<br />

construction, AVS can replicate any brick in<br />

the market via patented, lightweight acrylic<br />

brick slips. The system is not just limited to<br />

using acrylic brick slips as the final facade<br />

Technical Approval<br />

The AVS system has been rigorously tested,<br />

resulting in compliance with all UK Building<br />

Regulations and became British Board of<br />

Agrément approved (Cert No: 15/5211) in May<br />

2015. It is the only ventilated system in the UK<br />

to be BBA certified with an external acrylic<br />

The initial product development remit was to<br />

design a ventilated system that would<br />

replicate traditional building aesthetics, whilst<br />

providing a lightweight solution that could be<br />

fixed directly to structural timber systems.<br />

Alumasc’s main goal was to ensure the system<br />

was engineered to deliver structural stability<br />

across all applications whilst providing<br />

adaptability to all forms of structural timber<br />

construction.<br />

This innovative, engineered system provides<br />

the solution to overcome the fundamental<br />

issues of the brick shortages. AVS, as an<br />

offsite manufactured system, improves<br />

efficiency and speed of construction,<br />

addresses skills shortages and enhances the<br />

quality of finish, whilst delivering the final<br />

aesthetics to meet the exacting requirements<br />

of architects, designers and housebuilders.<br />

The product offers specifiers a ventilated<br />

cladding solution for timber frame<br />

construction (open and closed panel<br />

technology), together with volumetric<br />

modular and structurally insulated panel<br />

systems (SIPS). It protects the fabric of the<br />

building whilst providing a wide choice of<br />

aesthetic options.<br />

finish - it is also approved for use with<br />

textures, through-coloured silicone renders,<br />

along with an extensive range of dashing<br />

renders.<br />

AVS is erected via Alumasc’s network of<br />

registered installers to ensure correct<br />

application onsite. The AVS installer training<br />

programme is independantly assessed and<br />

approved by the BBA. AVS comes with a 10<br />

year warranty offer for all projects installed<br />

by an Alumasc registered contractor.<br />

brick slip finish and offers an industry-leading<br />

A2 rating, providing the building with<br />

improved fire performance when compared to<br />

other cladding solutions.<br />

During the development of the system,<br />

Alumasc worked very closely with a number<br />

of companies and bodies to ensure AVS would<br />

meet the demands of the offsite and onsite<br />

construction industry, whilst providing<br />

optimum performance and longevity. These<br />

organisations include CCG, Exova Fire<br />

Research, Warrington (fire testing); Lucideon<br />

(UKAS a<strong>cc</strong>redited testing body); Pell<br />

Frishmann (Consultant Engineers) and the<br />

British Board of Agrément.<br />

AVS is the solution to overcome current<br />

construction industry skills issues and is wellpositioned<br />

to be part of the building<br />

technology of the future.<br />

Building fabric in the firing line<br />

Technical Editor Bruce Meechan reports from the Inmarsat Centre in London about a wide ranging conference<br />

staged there on November 18th.<br />

and perhaps this points to why so many of our<br />

modern or recently overclad properties suffer<br />

from condensation problems.<br />

Several of the speakers touched on the subject<br />

of dwellings overheating, with the various<br />

remedies recommended including greater use<br />

of thermal mass and concrete or masonry<br />

elements, better attention to the detailing and<br />

construction of ductwork serving MVHR or<br />

other ventilation systems, and also solar<br />

shading or shutters.<br />

There have been many times when I have<br />

sat through a chairman’s opening<br />

remarks at a construction conference<br />

and wondered if I wouldn’t have been better<br />

hanging around in the foyer for a second cup<br />

of tea – but not so with what Rob Pannell from<br />

the Zero Carbon Hub had to say at the Fabric<br />

First event, staged in London’s very<br />

a<strong>cc</strong>essible Inmarsat Building by Radar<br />

Communications.<br />

While I don’t share the Zero Carbon Hub’s<br />

certainty about Global warming, amongst his<br />

many observations that struck a chord with me<br />

were that Government has failed to show any<br />

real leadership on energy matters, whilst “firing<br />

shots all over the place”; and also that he would<br />

like to have a meeting with Minister Amber<br />

Rudd, to “explain to her what Fabric First<br />

means.”<br />

Mr Pannell also shares my scepticism over the<br />

value of Energy Performance Certificates or<br />

EPCs; though while I believe they are not nearly<br />

specific enough in assessing the nature of the<br />

building fabric, his view is based on the fact<br />

that buildings are failing to reach their target<br />

standards.<br />

In his own recently constructed home there are<br />

apparently draughts coming from behind the<br />

electric sockets; while a later speaker<br />

expressed the view that because the UK’s<br />

climate is relatively mild we simply can’t be<br />

bothered to get our buildings right. If that is the<br />

case, achieving the Government’s commitments<br />

on carbon reduction really is going to be a<br />

problem.<br />

This disturbing perspective came from Gordon<br />

32<br />

Alistair Donn, Willmott Dixon and<br />

Kim Mead, Passive House Trust<br />

during the afternoon Q&A sessions<br />

Evans of the YOOP Architectural Practice who<br />

insisted that the Canadians build far better<br />

than us – in particular achieving very good<br />

airtightness and continuity of insulation –<br />

despite targeting less onerous U-values than<br />

are routinely used in the UK.<br />

Gordon Evans of the YOOP<br />

Architectural Practice<br />

considers that the Canadians<br />

build far better than us – in<br />

particular achieving very<br />

good airtightness and<br />

continuity of insulation –<br />

despite targeting less<br />

onerous U-values than are<br />

routinely used in the UK<br />

Although Gordon presented an overview of the<br />

Boxtree social housing development in Harrow,<br />

which has won many awards and so impressed<br />

the INCA judging panel I was on, he cited a<br />

variety of projects from around the globe that<br />

his practice has been involved on. Struck by the<br />

variety of building solutions they had used –<br />

including ICF and timber frame – I asked him<br />

during the Q&A session about the importance<br />

he and his colleagues put on local climate in<br />

relation to such decisions.<br />

His response was unambiguous, commenting<br />

on one which was internally insulated to<br />

counter the predominantly humid conditions,<br />

Kym Mead gave one of the afternoon’s best<br />

presentations on behalf of the PassivHaus Trust<br />

– those most airtight of buildings – and<br />

surprised many of us by reporting that the UK<br />

has only recently passed the 300 mark in terms<br />

of fully certificated projects. He did point out,<br />

however, that a block of flats counts as just one<br />

PassivHaus property.<br />

He also asserted that: “Done properly, a<br />

PassivHaus building will not suffer overheating<br />

in summer.”<br />

While the whole event was well worth the<br />

attention of those present – and it seemed<br />

many had decided not to attend due to the<br />

heightened security fears in London after the<br />

attacks in France – the case studies were<br />

probably of most value to delegates.<br />

Alasdair Donn of Wilmott Dixon for instance,<br />

talked about the Centre for Medicine at<br />

Leicester University which has been built to<br />

PassivHaus standards, and offered numerous<br />

insights into such issues as insulating bracketry<br />

and the need to carry out air leakage testing on<br />

zones as the structure progresses.<br />

We will cover some of the systems being shown<br />

in the a<strong>cc</strong>ompanying exhibition in our January<br />

edition.<br />

The Inmarsat Centre sits above Old Street<br />

Tube station on City Road and is an ideal<br />

facility for conferences of this size.

‘Traditional’ approach to island<br />

PassivHaus properties<br />

<strong>MMC</strong> Magazine’s Bruce Meechan reports on a substantial low energy development by one of the south-east of<br />

England’s largest housing associations.<br />

Many of our readers will be aware of<br />

the Isle-of-Wight’s desire to become<br />

a Zero Carbon beacon for other<br />

parts of the country – by maximizing the use<br />

of renewable energy sources as well as<br />

cutting usage across its properties – but the<br />

ambition has been brought a step closer<br />

thanks to the decision of Southern Housing<br />

Group to build 28 new homes to PassivHaus<br />

Standard. .<br />

Cameron Close in Freshwater on the island’s<br />

western side is a £4.2 million development of<br />

16 semi-detached family homes and a dozen<br />

sheltered apartments; built on a 1.5 acre site<br />

formerly o<strong>cc</strong>upied by an earlier retirement<br />

scheme belonging to the RSL.<br />

Interestingly, the development began its life<br />

being designed by PCKO Architects to satisfy<br />

the higher levels of the Code for Sustainable<br />

Homes, before Southern Housing Group’s<br />

Regional Manager viewed another PassivHaus<br />

project in Portland, Dorset and recognised the<br />

potential for doing the same at Cameron<br />

Close.<br />

As Alan Townshend, Development Director at<br />

Southern Housing Group, explained to <strong>MMC</strong><br />

Magazine: “We decided to make Cameron<br />

Close a PassivHaus development as it best<br />

meets the group’s sustainability objectives<br />

without the need to provide expensive<br />

renewable technology. We moved our current<br />

residents to a new modern sheltered housing<br />

scheme, Whitmore Court, that best met their<br />

needs and used the existing site to create<br />

those environmentally friendly family homes.<br />

“As part of our aim to provide sustainable<br />

tenures, the group is always looking at how we<br />

can improve the quality of the homes we<br />

provide, so not only does this ‘fabric first’<br />

approach provide an environmentally friendly<br />

solution for building these homes, it will also<br />

give the residents of Cameron Close<br />

significant and long-term savings on their<br />

energy bills.<br />

“When we decided to go down the traditional<br />

route rather than timber frame, Celcon was<br />

approached, and it was the company that<br />

suggested thin-joint construction as the best<br />

solution. Celcon was very helpful with<br />

technical guidance and providing training for<br />

the operatives from Stoneham Construction<br />

on the Isle-of-Wight who were going to lay the<br />

thin-joint system.”<br />

The exterior walls were finished with a<br />

proprietary render system applied to 230 mm<br />

of insulation, fixed over the 200 thick Celcon<br />

blockwork. This was parge coated on the inside<br />

in order to achieve an excellent level of<br />

airtightness – typically 0.<strong>48</strong> m3/m2/hr at 50<br />

Pascals. The contractor then formed a metal<br />

studded batten cavity behind a final lining of<br />

plasterboard which provides a service void.<br />

Also of major importance to controlling air<br />

leakage was the selection of triple glazed,<br />

aluminium clad windows from Munster Joinery,<br />

and exterior doors manufactured by Internorm.<br />

Then at first floor ceiling level, a polythene<br />

membrane was installed above the<br />

plasterboard soffit. Overall the su<strong>cc</strong>ess of all<br />

these measures is also the result of a<br />

‘PassivHaus Champion’ having been employed<br />

on site to monitor all of these details’<br />

execution; along with the multiple service<br />

penetrations.<br />

The ground floor construction features the use<br />

of a beam and block floor system, overlaid with<br />

250 mm of Kingspan Kootherm K3 insulation<br />

and then a further concrete slab which also<br />

helps add thermal mass to the living space.<br />

Of course the main idea of using such high<br />

levels of insulation in a PassivHaus<br />

construction is to keep energy usage down to a<br />

very low level; and often you will find properties<br />

just feature a wood burning stove to ‘top up’<br />

the heating on the coldest days. At Cameron<br />

Close, the solution chosen was to give every<br />

home a small combination boiler to not just<br />

supply the kitchen and bathroom with hot<br />

water, but also to heat a towel rail and a couple<br />

of radiators. One is in the hallway while another<br />

is situated in the lounge; offering visual<br />

comfort as much as physical warmth. Zehnder<br />

Comfoair MVHR units are also installed in every<br />

home to further reduce heat loss and ensure<br />

necessary air changes are achieved.<br />

Work actually started on site in early<br />

September 2013 with final planning permission<br />

having been granted in the previous December,<br />

before going through the OJEU tendering<br />

process. Alan recalled: “The tenders for<br />

building to PassivHaus standards actually came<br />

back higher than we had expected, but we had<br />

already secured HCA funding and the Isle-of-<br />

Wight Council also provided some finance to<br />

support the PassivHaus element to the build as<br />

it was in line with their Green Island agenda.<br />

“Our initial estimation is that the entire<br />

scheme could save up to £25,000 a year in<br />

energy costs, with some residents being able<br />

to save up to £900 in a three bedroom home.”<br />

The PassivHaus Institute has already precertified<br />

all fixtures and fittings to ensure that<br />

the required heating and primary energy limits<br />

are met; the homes are currently going<br />

through the PassivHaus certification process.<br />

Alan concluded saying: “If we were going to<br />

develop another PassivHaus project I think we<br />

might well use the thin-joint masonry again, as<br />

it proved very su<strong>cc</strong>essful, though we would<br />

probably revert to a traditional brickwork<br />

outer elevation as the render proved difficult<br />

to apply in the poor weather conditions<br />

suffered.”<br />

The properties are now the subject of post<br />

o<strong>cc</strong>upation monitoring using heat meters and<br />

other sensors.<br />

• Over the last 110 years, Southern Housing<br />

Group has become one of the largest<br />

housing associations in the south of<br />

England, housing more than 67,000<br />

residents, managing almost 30,000<br />

homes, employing nearly 900 people and<br />

working with more than 70 local<br />

authorities across the South East,<br />

including the Isle of Wight.<br />

• Our vision, ‘A business with social<br />

objectives’, draws on our history and<br />

traditions while recognising the need to<br />

change with changes in the housing<br />

sector.<br />

• Our social and economic regeneration<br />

work is undertaken to improve the lives of<br />

residents in the communities and<br />

neighbourhoods where we build and<br />

manage homes. It provides tangible<br />

evidence of our commitment to building<br />

sustainable communities.<br />

• Southern Housing Group is a member of<br />

the g15, which represents London's 15<br />

largest housing associations. The g15<br />

houses one in ten Londoners and builds a<br />

quarter of London's new homes. We are<br />

working to solve the housing crisis by<br />

delivering good quality, affordable homes<br />

of all types. To find out more about the<br />

g15's work please visit g15london.org.uk<br />

“As part of our aim to provide<br />

sustainable tenures, the group is always<br />

looking at how we can improve the<br />

quality of the homes we provide, so not<br />

only does this ‘fabric first’ approach<br />

provide an environmentally friendly<br />

solution for building these homes, it will<br />

also give the residents of Cameron Close<br />

significant and long-term savings on<br />

their energy bills.”<br />

ErP means level playing field for heating<br />

Mitsubishi Electric has produced a free, CPD-a<strong>cc</strong>redited guide to the new Energy Related Products Directive or ErP<br />

(2009/125/EC), which is a key part of the European Union’s drive to encourage consumers to use more energy<br />

efficient products.<br />

To highlight the requirements under ErP<br />

the company has also released a short<br />

video which explains how the Directive<br />

is designed to help phase out lower<br />

performing products whilst having a positive<br />

impact on the emissions levels across Europe<br />

and increase the share of renewable energies<br />

by 20 per cent.<br />

The ErP Directive, which came into force at the<br />

end of September 2015, now means that<br />

commercial and residential heating products<br />

will need to display an energy label, so that<br />

consumers can quickly understand the energy<br />

efficiency of the products they purchase.<br />

A similar market transformation strategy has<br />

already proved highly su<strong>cc</strong>essful with consumer<br />

goods such as fridges and freezers, where it is<br />

now very rare to find anything below an A rated<br />

product available on the high street.<br />

“There are two parts to the ErP strategy which<br />

affect both manufacturers and installers and<br />

everyone involved needs to understand how<br />

this will change the heating market”, explains<br />

Max Halliwell, who fronts the video on behalf of<br />

the company.<br />

Firstly, the ErP requires manufacturers to<br />

produce energy-using products that meet<br />

stringent minimum performance standards.<br />

And secondly, these products must be clearly<br />

labelled using a standard methodology so that<br />

consumers can quickly understand the energy<br />

efficiency of the products they purchase.<br />

These labels will show the efficiency ranging<br />

from the most efficient A++ to the least<br />

efficient G and will be clearly marked with<br />

coloured bars; from green (the most efficient)<br />

all the way down to red (least efficient).<br />

36<br />

The details on the label will identify the<br />

efficiency band for heating, and where relevant,<br />

hot water production and where relevant, noise,<br />

emissions and power consumption.<br />

“For heat pumps they will also indicate the<br />

three different climate zones within Europe<br />

which is important<br />

here because the<br />

UK is split<br />

between all three<br />

of these zones”,<br />

adds Halliwell.<br />

“We feel that<br />

this is now<br />

levelling the<br />

playing field for<br />

heating<br />

products which<br />

will allow<br />

consumers to<br />

see exactly<br />

how energy<br />

efficient the types of<br />

heating they choose are”.<br />

ErP is a significant piece of legislation that will<br />

have a major impact on the sale and use of<br />

heating systems in the UK. As such, the<br />

requirements of ErP is already being embedded<br />

into legislation on the energy efficiency of<br />

buildings and as incentive schemes for<br />

renewable technologies.<br />

In order to apply for Renewable Heat Incentive<br />

(RHI) payments, heating systems will now<br />

needs to comply with the Microgeneration<br />

Certification Scheme (MCS), which sets<br />

industry standards for products used to<br />

produce heat from renewable sources.<br />

In May 2015, the MCS published a new seasonal<br />

coefficient of performance (SCOP) calculator. It<br />

also updated its Installation Standard for heat<br />

pumps as a direct result of the introduction of<br />

ErP. The introduction of this SCOP calculator<br />

will enable certification bodies to use a<br />

standard method based on ErP to establish<br />

whether a heat pump is compliant.<br />

“This is important because in the past, the<br />

efficiency of a heating system was based on<br />

what is known as the coefficient of<br />

performance or COP”, explains<br />

Halliwell, “but this<br />

shows a single point in<br />

time, which is never a<br />

good indication on how<br />

efficiently it will perform<br />

all year round, whereas<br />

SCOP shows the<br />

performance across the<br />

different seasons and<br />

gives a much more<br />

a<strong>cc</strong>urate indication of<br />

efficiency”.<br />

The dedicated video can be<br />

viewed at the company’s<br />

YouTube Channel and<br />

further information on the<br />

entire range of A++ heat pumps can be found<br />

on the dedicated Youtube channel at<br />

youtu.be/4tzKoyzRMOU or at ecodan.co.uk.<br />

The CPD Guide covers both main parts of the<br />

ErP: the EcoDesign regulations and the Energy<br />

Labelling regulations. The guide explains how<br />

the labelling is designed to help businesses and<br />

homeowners understand the benefits of each<br />

technology and focuses on the importance of<br />

ErP in relation to legislation such as the<br />

Renewable Heat Incentive (RHI).<br />

Ecobuild supports delivery of infrastructure revolution<br />

with new ice partnership and zone for 2016<br />

A new partnership between Ecobuild, the UK’s leading event for the construction industry, and the Institution of Civil Engineers<br />

(ICE) has been launched today ahead of the 2016 Ecobuild conference. The partnership will focus around a major new conference<br />

and exhibition centre – The Infrastructure Revolution Hub – which will enable industry to come together and discuss ways it can<br />

maximise the opportunity for growth, following Government’s commitment to infrastructure as key economic driver.<br />

At the heart of the Hub will be a large<br />

conference area which will debate the<br />

key issues for the infrastructure<br />

sector across the three days of Ecobuild. The<br />

Hub will also feature products and services<br />

key to this growth sector and the ICE genius<br />

networking bar, making it one of the key<br />

destinations at Ecobuild for infrastructure<br />

professionals looking to make connections<br />

with the people that matter. .<br />

TThe infrastructure seminars held in the<br />

Infrastructure Revolution Hub will feature the<br />

UK’s leading contractors and industry experts.<br />

With a mix of keynote speakers and panel<br />

sessions, the seminars will focus on future<br />

challenges, opportunities and global best<br />

practice. Discussions will cover three overall<br />

themes - ‘Creating the infrastructure of the<br />

future’, ‘Small cities’, and ‘Modelling climate<br />

change’, including decarbonising urban<br />

infrastructure, energy generation, unlocking<br />

private capital, bespoke planning, collaboration<br />

opportunities, modelling demand of growing<br />

populations, and flood risk management and<br />

mitigation.<br />

The partnership between ICE and Ecobuild<br />

follows Government’s announcement of a<br />

National Infrastructure Commission – an<br />

independent body that will enable longer term,<br />

strategic decisions to be made on<br />

infrastructure. Government has also committed<br />

to investing £100 billion in new infrastructure<br />

projects in this parliament. The industry has a<br />

crucial part to play and the new Infrastructure<br />

Revolution Hub will bring the key players<br />

together to drive forward change and<br />

innovation.<br />

Leading architect and member of the new<br />

National Infrastructure Commission, Sadie<br />

Morgan, will also be delivering a session on day<br />

two of the Ecobuild 2016 conference.<br />

Nathan Baker, ICE’s Director of Engineering<br />

Knowledge, said: “The societal benefit of<br />

effectively procured and managed<br />

infrastructure is immense. The need for<br />

increased collaboration, innovation and<br />

managing risk has never been higher than<br />

today. To create sustainable infrastructure, it is<br />

essential that we embrace new methods of<br />

working, increase the use of technology and<br />

new materials and develop a highly skilled,<br />

diverse workforce. The new Hub will help to<br />

bring these challenges and opportunities to the<br />

fore and encourage positive action to be<br />

taken.”<br />

Martin Hurn, Ecobuild Event Director<br />

commented: “The infrastructure sector is a key<br />

driver of construction industry growth with the<br />

Government putting a major focus on delivery<br />

of infrastructure pipeline projects, and the<br />

recent strong output figures boosted by the<br />

new Commission pointing to sustained<br />

performance. The new Hub will enable the<br />

sector to come together in 2016 and have the<br />

conversation around the shared agenda for<br />

delivery of the Infrastructure Revolution.”<br />

Ecobuild 2016 takes place at ExCeL,<br />

London from 8th to 10th March<br />

2016. For further information about<br />

an exclusive development of 336 luxury apartments in North London.<br />

Two circular towers presented a major technical<br />

challenge for Shackerley and Stanmore<br />

Curved facade panels have been cut from solid blocks of engineered stone and specially prefabricated<br />

Prefabricated engineered stone façades<br />

Shackerley has supplied 2400m 2 of fully<br />

prefabricated Sureclad ® engineered stone<br />

cladding for the lower storeys of the nine<br />

apartment buildings that form this stunning<br />

complex, designed by Stockwool and developed<br />

by St James, part of the Berkeley Group.<br />

The engineered stone, in a natural limestone<br />

colourway and honed finish, provides a<br />

premium quality aesthetic at eye level<br />

throughout the development, contrasting with<br />

the lighter coloured insulated render of the<br />

upper storeys.<br />

Large format curved panels<br />

Two of the buildings feature circular towers<br />

calling for smooth and flawless rounded<br />

façades, which presented Shackerley and Kent<br />

based specialist façade installation contractor<br />

Stanmore with a significant technical challenge.<br />

Shackerley’s Sureclad ® Hang On system had to<br />

be customised to cater for large format curved<br />

panels, cut to a radius from solid blocks of<br />

engineered stone. Additional challenges<br />

included the design of elegantly faceted<br />

façades, using more traditionally formatted flat<br />

panels, to clad curved elevations of adjacent<br />

buildings, designed to reflect the ‘horseshoeshaped’<br />

design of the complex.<br />

Close collaboration<br />

Because of the very individual nature of this<br />

project, and in particular the use of curved<br />

large format engineered stone, Shackerley and<br />

Stanmore worked very closely together to<br />

ensure the developer’s requirements were met.<br />

Bespoke solutions were required at every stage,<br />

from the design of the Sureclad ® façades to the<br />

meticulous scheduling and non-standard<br />

palletisation of the prefabricated system for<br />

safe delivery to site. To ensure the installation<br />

went smoothly, Stanmore’s installers also<br />

visited Shackerley to receive expert training in<br />

the use of the Sureclad ® system.<br />

Testing to NHBC criteria<br />

As this was the first time that the Sureclad ®<br />

system had been used in conjunction with<br />

curved engineered stone panels, the two<br />

companies arranged for the bespoke Sureclad ®<br />

system to be tested at VINCI Technology Centre<br />

UK where it was shown to meet all NHBC<br />

criteria.<br />

Su<strong>cc</strong>essful installation<br />

Stanmore Commercial Director Peter Baker<br />

said: “We were responsible for delivering all the<br />

external façades, curtain walling, doors,<br />

windows and other external finishes on this<br />

project but the engineered stone cladding was<br />

by far the most highly valued element of the<br />

job. Close collaboration with our supplier was<br />

absolutely crucial. We hadn’t worked with<br />

Shackerley or its Sureclad ® façade system<br />

before, and it was also the first time that either<br />

party had worked with curved engineered stone<br />

panels, so there were many challenges to<br />

overcome.<br />

“However, by meticulously planning and<br />

modelling the installation and working hand in<br />

hand with Shackerley’s technical team, we<br />

achieved superb results for our client. The<br />

overall experience was very positive and we’re<br />

looking forward to working on other Sureclad ®<br />

projects in the future.”<br />

Award winning development<br />

Construction Director at St James, Brian<br />

Paterson, commented: “It was only when we<br />

came to value engineer the Kew Bridge West<br />

project that Shackerley’s system was brought<br />

to our attention. As a result of switching the<br />

engineered stone specification to Sureclad ® ,<br />

we’ve undoubtedly benefitted from a more<br />

flexible and lighter façade solution than<br />

originally planned and, most importantly, from<br />

38


Faceted cladding was installed to reflect the horseshoe shape of the development<br />

very substantial cost savings, whilst still<br />

achieving our architects’ original design<br />

intention.<br />

He concluded: “We’re delighted with the results<br />

and the project has received very favourable<br />

feedback from colleagues throughout the<br />

Berkeley Group. The quality of Kew Bridge<br />

West has also been recognised within the wider<br />

industry, and in October, St James received an<br />

NHBC Seal of Excellence Award for achieving<br />

the highest standards in house building at this<br />

prestigious development.”<br />

“...As a result of switching<br />

the engineered stone<br />

specification to Sureclad ® ,<br />

we’ve undoubtedly<br />

benefitted from a more<br />

flexible and lighter façade<br />

solution than originally<br />

planned...”<br />

Sureclad ® versatility<br />

Shackerley has su<strong>cc</strong>essfully clad hundreds of<br />

buildings, including many high profile<br />

developments, with its Sureclad ® ceramic<br />

granite cladding façade systems and is the<br />

clear market leader in the UK. Highly<br />

specialised manufacturing facilities at its ISO<br />

9001 certified factory include bespoke diamond<br />

tipped undercut drilling machines that provide<br />

recesses for undercut anchors that are used to<br />

prefabricate every Sureclad ® façade panel. As<br />

the Kew Bridge West development shows, these<br />

facilities are now being employed to<br />

prefabricate large format engineered stone,<br />

including curved façade panels, in exactly the<br />

same way, for installation as part of a Sureclad ®<br />

system.<br />

The Great Debate – Is Offsite Construction<br />

the answer to the delivery challenge faced<br />

by the UK Construction Industry?<br />

With turnover predicted to reach £7billion by 2018 has the offsite construction sector finally found a place on the<br />

mainstream construction agenda? Could it indeed make the difference to the UK construction industry in its quest<br />

to deliver 200,000 new homes per year as well as new schools, student a<strong>cc</strong>ommodation, and commercial buildings?<br />

Mike Stevenson<br />

The answer to these and other questions<br />

were the topic of two very lively<br />

debates at the recent inaugural offsite<br />

construction show. The debates were hosted<br />

by The Fabric First Academy, for whom Mike<br />

Stevenson Development of founding partner<br />

Sidey set the scene..<br />

“Being at an offsite construction show seemed<br />

to us to be the ideal opportunity to debate the<br />

merits of offsite construction in the context of<br />

the wider industry, the challenges it faces, and<br />

the positive benefits it can deliver to the UK<br />

construction industry as it seeks to deliver<br />

unprecedented levels of new homes, student<br />

a<strong>cc</strong>ommodation buildings, schools and<br />

commercial buildings”.<br />

“What we didn’t want was simply advocates of<br />

offsite construction saying how good it was – in<br />

fact we wanted the opposite. We wanted to find<br />

out what a cross section of industry people<br />

really thought about it; I think it is fair to say<br />

that those who attended didn’t go home<br />

disappointed, and hopefully they went away<br />

with more information and knowledge than<br />

they came with”.<br />

“Indeed knowledge is a great place to start. We<br />

asked the question as to why – although the<br />

offsite sector is on course to hit £7billion by<br />

2018 – there was still a resistance or reluctance<br />

to engage with this method of construction<br />

amongst so many”.<br />

“The view from the panel was that there was a<br />

real knowledge gap when it came to offsite<br />

methods and understanding the achievable<br />

benefits of building this way. Starting right at<br />

the beginning with architecture and design it<br />

was recognised that offsite did not form a big<br />

enough part of their learning, and very few<br />

architect’s practices actually design with offsite<br />

in mind from the outset; more so the appointed<br />

contractor looks at already agreed designs and<br />

only then see if offsite construction methods<br />

might be suitable to bring the scheme to life”.<br />

“This is a really key point; with so many sites<br />

now in tight inner city and urban locations the<br />

restrictions are such that building traditionally<br />

is often at best extremely difficult &<br />

problematic but at times just unfeasible. It is<br />

these restrictions – unaddressed at the outset –<br />

which can lead to costs running away from the<br />

agreed budget, and delivery times slipping<br />

away”.<br />

“For clients facing the twin pressures of budget<br />

constraint and needing to deliver quickly<br />

budget slippage is simply not a<strong>cc</strong>eptable, and<br />

neither is late delivery with the demands upon<br />

them to provide a<strong>cc</strong>ommodation for a growing<br />

population in need of their support. Indeed it<br />

is the very essence of what offsite construction<br />

can bring – cost and delivery predictability<br />

which is seeing more and more people sit up<br />

and take notice”.<br />

“Stemming further from this was a realisation<br />

that the often spoken about labour and skills<br />

shortages are now really starting to bite, hitting<br />

not only on site, but actually in roles which are<br />

responsible for the design and development<br />

stages of building in the first place. Again, the<br />

same message - there is a knowledge gap to be<br />

filled as well as a skills gap. And talking of<br />

skills, a<strong>cc</strong>ording to the panel the UK<br />

construction industry is facing a loss of<br />

700,000 construction personnel over the next<br />

five years through entirely natural processes”.<br />

“The view was that delivering through offsite<br />

construction can reduce the labour<br />

requirement on any contract by up-to 25%, a<br />

number which could rise further as more<br />

construction is done this way”.<br />

“But perhaps the biggest debate was why does<br />

there appear to be such a resistance at<br />

constructor level to engaging with offsite and<br />

then seeing it through to delivery? Clearly<br />

40


there are many of the major construction<br />

companies now exploring offsite fully as they<br />

start to understand the benefits of cost<br />

predictability and delivery against those of<br />

traditional building methods and the need to<br />

guarantee their clients exactly what they ask<br />

for to an a<strong>cc</strong>eptable standard, on time and to<br />

budget”.<br />

“Coming out loud and clear from the debates<br />

was the on-going disconnect between design<br />

teams and construction teams. Too few of the<br />

buildings which are developed for offsite<br />

construction actually reach the site stages still<br />

as offsite manufactured schemes; yet the<br />

implications of this have been proven to be<br />

significant – with disappointed clients being<br />

upper most”.<br />

“Undoubtedly design teams are increasingly<br />

starting to work collaboratively with the offsite<br />

sector to specify developed solutions which will<br />

deliver ‘as built’ buildings which perform as<br />

they were specified and designed to do in the<br />

first place, thus closing the renowned<br />

performance gap of circa 20%. This is in<br />

addition to projects delivered on time and to<br />

budget”.<br />

“However contractors and developers seem to<br />

retain a very different view in too many<br />

instances, and see their role as being to ‘deconstruct’<br />

the design solutions; to break them<br />

down into their individual components for<br />

procurement purposes ‘because it is cheaper’.<br />

This is entirely counter to the principles of<br />

offsite construction, which is all about solutions<br />

that ensure all the components work together,<br />

including the key joints and interfaces, to<br />

guarantee the performance of the structure.<br />

Who looks at a car and says right I can build<br />

that cheaper by sourcing all the components<br />

separately. It may look like the original design<br />

but it’s very unlikely to perform as well as the<br />

one sourced from the manufacturer”.<br />

“This was an emotional area of debate, and the<br />

general feeling was that construction is not<br />

modern enough in its thinking; it is not<br />

collaborating enough; there’s too much conflict;<br />

the answers lay in the supply chain;<br />

constructors need to embrace working with the<br />

supply chain as a real positive”. “Clearly this is<br />

a debate which is going to run and run”.<br />

Article ><br />

Value engineering –<br />

what’s it all about?<br />

As the construction industry strives to provide the optimum building solution, just how can companies today<br />

differentiate themselves and ensure they are offering best value?<br />

Lincoln gateway<br />

Steve Thompson, Managing Director of<br />

light steel frame manufacturer, EOS<br />

Facades explains how they are using<br />

value engineering and Design for Manufacture<br />

and Assembly (DfMA) to meet the demands of<br />

today’s construction industry.<br />

Value Engineering – What is it?<br />

Today’s customers are savvier, more<br />

commercially aware and they expect more for<br />

their money. As manufacturers and service<br />

providers, we need to react and meet this<br />

demand, or risk losing out.<br />

But before we can do this, we need to<br />

understand what value really is.<br />

Assessing best value depends on the objectives<br />

set - speed of construction, build costs or the<br />

development of a sustainable, energy efficient<br />

building - or perhaps a combination of all.<br />

Adopting a ‘one system fits all approach’ will<br />

not necessarily deliver best value. It is not<br />

about economies of scale but it is about an<br />

optimised approach - working with the client to<br />

select the right solution, at the right price, to<br />

deliver the right performance.<br />

Adding Value: Design for Manufacture and<br />

Assembly<br />

As a manufacturer of steel solutions, EOS<br />

Facades take full advantage of offsite<br />

manufacturing techniques by adhering to<br />

Design for Manufacture and Assembly (DfMA)<br />

protocols. DfMA is now recognised as the<br />

foundation for concurrent engineering<br />

processes to streamline and fully optimise the<br />

structure. The process aids the building design<br />

process and helps to identify, quantify and<br />

eliminate waste or inefficiency where possible.<br />

At EOS Facades we pride ourselves on driving<br />

quality through precision manufacturing whilst<br />

delivering a<strong>cc</strong>urate results on time and on<br />

budget.<br />

We have taken steps to ensure that DfMA is<br />

integrated throughout the design and<br />

manufacturing process. We have made<br />

considerable investment in developing<br />

technology to aide specification and design. We<br />

are totally committed to working with our<br />

clients on product and service innovations to<br />

help them gain a competitive advantage in the<br />

marketplace – delivering cost and time<br />

efficiencies.<br />

The EOS manufacturing facility is a 40,000 sq<br />

ft operation that houses state-of-the-art<br />

machinery and technology providing offsite<br />

systems and solutions that meet the needs of<br />

our customers. Our manufacturing facility is<br />

well equipped to cater for the demands of<br />

offsite construction and precision engineering.<br />

Our sophisticated roll-forming machines have<br />

embedded framing technology that enables<br />

production of self-jigging framing components<br />

that are ready for assembly, eliminating the<br />

need to manually cut onsite.<br />

All of our products are manufactured under<br />

strict quality management control which is fully<br />

compliant with BS EN ISO 9001:2008. Our<br />

a<strong>cc</strong>redited quality management systems and<br />

procedures eradicate onsite variability and<br />

ensure life time ‘in service’ performance and<br />

durability.<br />

Adding Value: Software and Building<br />

Information Modelling<br />

Precision built offsite products require the<br />

application of leading-edge technology and<br />

contemporary manufacturing processes. We<br />

have invested substantially in the latest<br />

software and hardware systems in steel frame<br />

42


production. Our systems combine the latest E-<br />

Frame technology platform with proven<br />

assembly processes, providing fully framed<br />

panels that do not require jigging.<br />

The Shard<br />

Sophisticated software transfers building<br />

design information directly to our production<br />

plant where we are able to manufacture to<br />

a<strong>cc</strong>uracies that exceed construction industry<br />

norms. Once the panels have been designed<br />

using our 3D Tekla modelling software, they are<br />

directly uploaded to the roll-forming machines,<br />

using a bespoke CAD/CAM interface, where<br />

they are produced to exact dimensions using<br />

CNC technology. Each stud is identified with an<br />

inkjet printer to match the assembly drawing<br />

and every frame has an identification label<br />

attached. This identifies the project, frame<br />

number, order number and site location on the<br />

GA site drawings so they can be positioned<br />

quickly to their onsite location.<br />

Adding Value: Product<br />

Product quality is essential. EOS only use<br />

minimum S390Nmm2 G275gsm steel (higher<br />

grades and coatings on request). By only using<br />

steel with a protective coating and design<br />

detailing that eliminates prolonged exposure,<br />

EOS are confident in the durability of our<br />

systems. Research has shown in these<br />

conditions coated steel has a potential life of<br />

over 1,000 years.<br />

The team at EOS support key industry<br />

standards and strive to exceed expectations on<br />

reliability and delivery. All of our products are<br />

manufactured to rigorous quality standards<br />

which are fully compliant with the Construction<br />

Products Regulations - EN 1090-1: 2009 + AL:<br />

2011. Our quality management systems are BS<br />

EN ISO 9001: 2008 registered.<br />

Victoria Halls London<br />

Adding Value: Cost<br />

We offer all-inclusive fixed price packages that<br />

are uniquely supplied with proprietary brackets<br />

and fixings required. All Double Studs/Opening<br />

Jambs/Lintels and Sills will be dispatched from<br />

our factory preassembled. This is a flexible<br />

service and should you require the product to<br />

arrive unassembled, EOS will pre-punch in the<br />

factory, ghost assemble and supply, together<br />

with all the necessary screws and special drill<br />

bits, for assembly and installation onsite.<br />

Adding Value: People<br />

EOS Facades are constantly striving to improve<br />

the way we work and the resulting benefits are<br />

passed onto our customers. Research &<br />

Development is a core focus of our business<br />

and it is not just down to one specific team, at<br />

EOS everybody is encouraged to put<br />

recommendations forward, whether this is a<br />

process or an alteration to a product – that way<br />

every part of our business can be enhanced.<br />

EOS also offer a total partner solution including<br />

application consultancy, structural design<br />

support and value engineering, as well as<br />

quality manufacturing.<br />

To meet the demands, we need people to make<br />

the change happen.<br />

Now the construction industry is starting to<br />

recognise the shift in needs of the client,<br />

manufacturers must ask themselves, are they<br />

well equipped to meet demands or will they risk<br />

losing out?<br />

For more information on EOS Facades’ products<br />

and services visit: www.eos-facades.co.uk<br />

Adding Value: Knowledge Sharing<br />

In a bid to share their extensive knowledge,<br />

EOS Facades are offering a series of CPD<br />

sessions, designed to highlight the various light<br />

gauge steel solutions available, and explain how<br />

these can be applied in real life scenarios.<br />

Medite & Smartply set sights<br />

on off-site construction<br />

Wood panels are the natural choice for developers and house builders looking to utilise the time, cost and quality benefits of offsite<br />

construction. In particular, engineered wood panels offer specifiers, timber frame manufacturers and contractors the<br />

enhanced flexibility, improved quality and superior safety to ensure the industry continues to build for the future.<br />

Leading manufacturers of engineered<br />

wood panels, Medite and SmartPly offer a<br />

wide range of high performance products<br />

for wall, floor and roof applications. From the<br />

breathable Medite Vent to the new SmartPly<br />

VapAirTight with integrated vapour control and<br />

air barrier properties – Medite and SmartPly<br />

provide high performance, environmentally<br />

friendly and easy to install products that are<br />

perfect for modern construction.<br />

Lessons in performance<br />

At the University of East Anglia’s (UEA)<br />

landmark development The Enterprise Centre,<br />

over 11,000m2 of SmartPly OSB3 was supplied<br />

for use in the structural timber frame.<br />

Manufactured using zero added formaldehyde,<br />

SmartPly OSB3 met the client and contractor’s<br />

strict requirements for proven performance<br />

and extremely low environmental impact.<br />

The build-up of the wall panels featured 18mm<br />

taped SmartPly OSB3 on the inside for racking<br />

and airtightness, followed by a 140mm cellulose<br />

insulated structural stud, a thermal break<br />

cavity filled with cellulose insulation and a<br />

second 63mm insulated stud.<br />

For projects where flame retardance is a<br />

prerequisite, SmartPly has developed SmartPly<br />

FR OSB3. Manufactured using Zeroignition<br />

Solution, a water based, eco-friendly, fire<br />

retardant, this penetrates into the wood<br />

strands to ensure best in class fire performance<br />

whilst fully maintaining structural integrity.<br />

At the construction of The Edge – a sevenstorey,<br />

timber frame a<strong>cc</strong>ommodation building<br />

for students of John Moores University and<br />

University of Liverpool – SmartPly FR OSB3 was<br />

specified over conventional post-treated wood<br />

panels due to its guaranteed consistency and<br />

excellent flame retardant properties.<br />

The future of OSB<br />

Environmental credentials are now a crucial<br />

requirement in modern construction. With<br />

Passivhaus and low energy construction<br />

growing in popularity, SmartPly developed a<br />

structural panel that meets these requirements.<br />

The new SmartPly VapAirTight OSB panel, for<br />

which a patent is pending, is specifically<br />

engineered to deliver outstanding levels of<br />

airtightness and vapour control.<br />

Each panel features alternating layers of wood<br />

strands coated with a high quality<br />

formaldehyde-free resin and wax binder system<br />

to deliver outstanding levels of airtightness. A<br />

specialist coating is then applied to ensure<br />

vapour resistance and provide a premium<br />

performance OSB solution for super-insulated<br />

and passive buildings and enabling the<br />

elimination of a traditional additional vapour<br />

control membrane.<br />

Breathe more easily<br />

When designing and building timber frame<br />

structures, the risk of interstitial condensation<br />

is a key consideration as it can lead to mould<br />

growth, health issues and can even compromise<br />

structural integrity. Medite Vent meets the<br />

need for a breathable panel for use in external<br />

sheathing for all types of timber frame<br />

construction, supporting a well-ventilated<br />

building design.<br />

Combining high racking strength in excess of<br />

Category 1 requirements with excellent vapour<br />

permeability and high weather resistance,<br />

Medite Vent is an ideal choice for the outer<br />

layer in ‘diffusion open’ wall and roofing<br />

applications. Medite Vent is also produced<br />

using zero-added formaldehyde and carries the<br />

CE mark in a<strong>cc</strong>ordance with EN 13986 – making<br />

it a sustainable, reliable and high performance<br />

choice for low energy construction projects.<br />

Engineered wood panels deliver quality,<br />

performance and durability for a wide range of<br />

structural and non-structural applications. The<br />

specialist ranges of high performance and<br />

environmentally friendly systems from<br />

SmartPly OSB and Medite MDF make them the<br />

natural choice for forward-thinking architects,<br />

specifiers and contractors.<br />

fast-track construction programme to develop a major new hotel in the centre of<br />

London - Motel One London-Tower Hill.<br />

“The major advantage with these products is the speed at which you can apply them<br />

– three or four times faster than manual application,” said Matt Smith, who runs the<br />

specialist subcontractor Spray Plastering Specialists appointed by McAleer & Rushe.<br />

“We have far greater control because there are fewer people on site. We have a team<br />

of just three people and we can do 30 rooms a week. We have one guy working ahead<br />

of us filling and jointing and two people spraying plaster,” he said.<br />

Knauf’s range of Ready Mixed Spray Plasters enable up to 1,000m2 per week can be<br />

finished by a three man gang, while surfaces can be emulsioned within 24 to <strong>48</strong><br />

hours, so the plaster can be applied by the same teams applying the paint finishes.<br />

They offer a range of finishes, including flat and smooth, textured, leathered, combed<br />

or rollered.<br />

First Street in<br />

Manchester gets a<br />

Home<br />

Prater has recently delivered the<br />

external cladding and roofing works at<br />

independent film hub and visual arts<br />

centre, Home, in First Street,<br />

Manchester. Completed in April 2015,<br />

Home forms part of a 20 acre<br />

development in the heart of<br />

Manchester city centre.<br />

Performing for zero carbon timber homes<br />

An example of how timber is playing a major role in the UK’s first eco-town NW Bicester is a<br />

collaboration between Stewart Milne Timber Systems and the A. Proctor Group, which is<br />

providing high thermal performance using off-site modules. The first phase of A2Dominion’s<br />

development in the new town is a project to deliver 393 homes with a ‘true zero carbon’<br />

rating and offering energy efficient, good quality, affordable housing.<br />

The A. Proctor Group has supplied its Roofshield and Reflectashield TF 0.81 membranes for<br />

pre-assembled modules. These pre-assembled elements enable a pair of semi-detached<br />

homes to be weathertight, secure and fully insulated within 72 hours.<br />

Roofshield is an air and vapour permeable roofing<br />

underlay which provides a high degree of water<br />

resistance; the product provides the most costeffective<br />

solution to controlling interstitial<br />

condensation in a pitched roof. Reflectashield TF 0.81 is<br />

a vapour permeable low emissivity membrane for use<br />

externally on timber frame buildings.<br />

Making light work of brick soffits<br />

Creating flawless brick-faced soffits and lintels has<br />

now become much simpler and quicker, thanks to a<br />

new lightweight stainless steel-based system<br />

developed by two industry-leading companies -<br />

brick support specialist Ancon Building Products<br />

and Ibstock Kevington – national manufacturer of<br />

brickwork and masonry special shapes and<br />

prefabricated components.<br />

The new Nexus® system combines a specially<br />

developed Ibstock Kevington lightweight brick-faced<br />

steel unit with Ancon’s tried and tested MDC<br />

stainless steel bracket angle support system. The system offers contractors easier handling<br />

coupled with maximum adjustability, both vertically and horizontally, for quick and simple<br />

alignment on site.<br />

Working to a tight deadline, the<br />

specialist contractor’s experience and<br />

proven capability on complex projects<br />

was crucial. Furthermore, Prater’s inhouse<br />

design team made an invaluable<br />

contribution to the project overall, and<br />

the ability to utilise off-site fabrication<br />

at one of Prater’s factories helped to<br />

overcome significant logistical<br />

challenges on-site.<br />

Prater was appointed by main<br />

contractor Wates in a contract worth<br />

£2.5m to deliver the roofing and<br />

cladding package for Home. Overall,<br />

Prater was responsible for installing<br />

over 51 units of Reynaers Curtain-<br />

Walling, a range of Reynaers CS68<br />

Doors and Hortons 2001 Sliding Door<br />

units, as well as 826 Trimo Rainscreen<br />

Composite Panels and Radmat’s<br />

Permaquik hot melt waterproofing<br />

system for the roofing works.<br />

www.prater.co.uk<br />

The new system offers considerable benefits over traditional cast concrete alternatives –<br />

cutting weight by more than half, which in most cases will allow the brick-faced units to be<br />

installed without specialist lifting equipment, and significant savings in installation time –<br />

making it particularly appropriate for fast-track or time-limited projects.<br />

Rebrand transforms Roan to Actavo<br />

www.ancon.co.uk/Nexus<br />

Roan Building Solutions has been transformed into Actavo as part of Siteserv’s rebranding of<br />

all its companies including EventServ, Deborah Services and Sierra Support Services, to come<br />

together as one unified team.<br />

Operating globally in over 100 locations, the move to Actavo comes against the backdrop of a<br />

number of large-scale contract wins internationally. The change sees a transformation from<br />

being a holding company with autonomously operating entities in to one company with<br />

actively-managed, inter-related business solutions.<br />

Welcoming the rebrand, CEO of Actavo Structural Division, Roger Hastie, said: “Actavo will<br />

continue to deliver the quality goods, services and expertise we provided as EventServ, for<br />

example. In addition to this, we will be offering customers greater choice and a<strong>cc</strong>ess to the<br />

capabilities of the entire Actavo Group.”<br />

Commenting on the rebrand name, Vivienne Walshe, marketing director at Actavo, said: “The<br />

inspiration for the name Actavo comes from Actus, the Latin word for performance. Actavo<br />

reflects our dedication to performance, to energy and to our active spirit in pursuit of<br />

excellence. Furthermore, it is a call to action to our entire workforce of 4,500+ employees,<br />

incentivising everyone to find new ways to work better, reach higher, go further, prosper and<br />

enable our customers to grow.”<br />
