IT IS SaId that time flies when you are 

having fun – well the past three years 

since taking up the role as Chairman at 

the Rome No-Dig Conference have just 

flown by. I have had great support from a 

lively Executive Committee and the ISTT 

staff, first Pat Nolan and John Castle and 

subsequently Kyoko Kondo and John 

Hemphill. The handover from John to 

John (a convenience for absent minded 

chairmen) went very smoothly and it has 

been a privilege for me to work with such 

professionals. In November we will have 

a vigorous election with nine candidates 

seeking to be voted onto the ESC; this 

has to be a sign of the good health of 

our organisation when senior trenchless 

practitioners are vying to be elected. I am 

sure when Professor Ray Sterling introduced 

the electoral procedure none of us 

ever thought it would be this competitive. 

I know that Professor Sam Ariaratnam 

going forward from the Singapore No-Dig 

will have a great team and I intend to stick 

around as a very active Past Chairman to 

help Sam wherever I am needed. 

In June I attended the Water Leaders 

Summit at the Singapore International 

Water Week and also the launch of the 

local society to be known as SgSTT. 

It was a great event with a number of 

international groups supported by their 

government and municipal agencies, good 

for networking and for promoting, with 

Westrade, our upcoming event. At one of 

the events, Minister Mentor Lee Kwan Yu, 

founder of the modern Singapore, spoke 

highly of the contribution of Trenchless 

Technology to the development of the 

clean, green Singapore with its deep 

sewer tunnel and recycled water usage. 

Accolades which testify to the merits of 

our business do not come from sources 

any more esteemed than Mr Lee. 

In July Sam Ariaratnam, Jason Luela and 

I spoke at the 2nd Latin American No-Dig 

and met with ABRATT to discuss their 

plans for our 2012 event. The progress 

ABRATT have made since the first regional 

event in 2008 and the way Brazil is taking 

to trenchless methods paves the way 

for a super show at a vibrant venue. I 

was most encouraged by the attitudes 

struck by the utility operators SABESP 

and COMGAS. In fact one speaker posed 

the question “Why would I use open cut 

when trenchless is so much better?” We 

are now working with ABRATT to look at 

ways to bring formal training and certification 

programs together to enhance their 

capital programs. 

I am currently preparing to speak at 

the trenchless events in the Ukraine, 

Czechoslovakia and Bulgaria and I 

will attend the UKSTT No-Dig Live at 

Stoneleigh and the ASTT Trenchless Live 

event in Coffs Harbour, so a busy autumn 

before the handover. I would like to take 

this opportunity to thank all members of 

ISTT and the Affiliated Societies for the 

warm welcome my wife Jan and I have 

received wherever we have been. I would 

also like to thank our publishers Great 

Southern Press and Benjamin Media who 

came before them, both organisations 

have done us proud and I think we will 

also be well pleased with Westrade when 

we meet together in Singapore. We have 

a truly great organisation which reflects 

the capabilities of our membership and 

our associates. This is just a beginning, 26 

years to develop an institution is no time 

at all so ever onwards and upwards with 

Dr Sam...

John Hemphill 

Istt Executive Director 

The OcTOber ISSue of Trenchless 

International is the final of the 2010. When 

this issue arrives, many of you will be off 

to Singapore to participate in the 28th 

Annual International No-Dig Conference 

and Exhibition. And what an event it promises 

to be. 

The Singapore No-Dig is shaping up 

to exceed the goals we set for it. Early 

registrations are above plan, as are 

exhibit space commitments. Attendees 

from every part of the world complement 

the strong showing of participants from 

Singapore, Malaysia, China and other 

countries in the region. We will end the 

year on a high note. 

Indeed 2010 has been a very successful 

year for the international 

trenchless community. 

In 2010, we will have added four new 

Affiliated Societies, significantly broadening 

the education and training reach of 

our Society. The first to join in 2010 was 

the Colombia Society (CSITT). Shortly 

after joining ISTT, CSITT hosted its first 

No-Dig in Cartagena on 3–4 June. ISTT 

Vice Chairman Samuel Ariaratnam and I 

were delighted to participate in this inaugural 

event. 

In September, Yasin Torun, Chairman, 

and Ahmet Gulec, Vice Chairman of the 

Turkish Society (TSITT) travelled to London 

to sign an affiliation agreement with ISTT. 

The Turkish trenchless society believes 

that the demand for trenchless methods in 

their region of the world is huge. 

The China Society (CSTT) and the 

Singapore Society (SgSTT) are set to join 

ISTT officially at the Singapore No-Dig 

conference. The addition of these two 

societies, in a very dynamic region, is a 

real plus for trenchless. All told, ISTT will 

welcome the New Year with 26 Affiliated 

Societies as members of the global 


The ISTT Board of Directors will meet 

in Singapore to map out future directions 

of ISTT. This meeting marks a milestone 

as we welcome Sam Ariaratnam as 

Chairman, replacing Dec Downey who 

has completed his three-year term as 

Chair. Derek Choi will become the new 

Vice Chairman. 

ISTT also will elect new members to 

the Executive Subcommittee – the 

management team of ISTT. Dec will 

remain active with ISTT in his capacity 

of Immediate Past Chairman. Under 

Dec’s leadership, ISTT added new members, 

hosted and co-hosted successful 

No-Digs and regional training seminars, 

and restored the financial health of the 

Society. The new leadership will doubtlessly 

wish to build on the successes of 

the past few years, while at the same 

time expand the efforts of ISTT in support 

of Affiliated Society programs and 

worldwide growth in the application of 

Trenchless Technology. I am sure Sam 

Ariaratnam will have more to say about the 

future direction of ISTT in his Chairman’s 

report in the January 2011 issue of 

Trenchless Technology. 

The No-Dig schedule institutes a goal 

of ISTT championed by Sam Ariaratnam 

to keep the event fresh and exciting by 

rotating the venue geographically among 

Europe, the Americas and Asia. The 2011 

No-Dig, hosted by the German Society 

(GSTT), will be held in Berlin, 2–5 May. It 

is hard not to be excited about the Berlin 

2011 No-Dig, which will be held in conjunction 

with the well regarded Wasser 

Berlin show. GSTT has begun accepting 

proposals for papers for presentation at 

the conference. Based on quality of these 

abstracts, we have reason to believe that 

the 2011 No-Dig conference will be of the 

highest technical quality. The combination 

of a strong technical conference in concert 

with Wasser Berlin makes the 2011 

No-Dig a “must attend” conference for 

our industry. 

The Brazilian Society (ABRATT) will host 

the 2012 No-Dig. The 2012 No-Dig will 

be held in Sao Paulo, Brazil in mid-May. 

The Sao Paulo No-Dig will mark the first 

International No-Dig to be held in South 

America. The venue for the 2013 No-Dig 

has not yet been determined. However, 

in keeping with ISTT’s policy of rotating 

No-Dig geographically, we anticipate 

this No-Dig will take place in Asia or the 

Pacific Rim. 

ISTT has had a banner year – a highly 

successful No-Dig, and a growing and 

diverse membership base – and the future 

looks equally bright.

Uk’s most ambitious 

One of the longest ever microtunnelling drives has commenced by 

J Murphy & sons Limited as part of the West East Link Main (WELM) pipeline 

scheme for United Utilities in Bury, UK. 

Using microtunnelling techniques, the company began the 650 m drive 

underneath the Metrolink line near Bury. Approximately 10 km of the pipeline 

route passes through Bury, including tunnels under the River Roch and 

the East Lancashire Railway. 

As the main contractor, Murphy is building the 54.5 km long, 1,200 mm 

diameter welded steel pipeline to enable the transportation of potable water 

bi-directionally from Prescot Reservoir near Liverpool, to Woodgate Hill 

Reservoir in Bury, Greater Manchester. 

Once complete in 2011, the project will be able to move 100 million litres 

of water per day.

the President has appointed business and labour leaders who will offer 

advice on how to promote Us exports, jobs, and growth. 

the purpose of the council is to support the President’s goal of doubling 

exports over five years, as well as supporting several million new jobs. 

Ms Andringa said the appointment “will involve her in promoting global visibility 

to ongoing export needs and concerns, as experienced by Vermeer and 

the larger industry it serves.”

Vincent Hart of Carollo Engineers said “the Geospatial team was very 

conscious of the utilities when physical examination (potholing) was 

required and kept safety at the forefront of the investigation. Locating critical 

utilities such as natural gas and chemical feed lines was important to 

the success of the project.”

SUPR (Specialized

The innovative Combisegment technology from Herrenknecht was used for the first time for 

the construction of a 500 meter long sanitary sewer tunnel in the south of Moscow. Combisegments 

use standard steel reinforced concrete segments with a corrosion-resistant liner 

incorporated into the segment that provides the necessary corrosion protection for sanitary 

sewer applications. During the production of Combisegments the liner is installed as a prefabricated 

glass-fiber reinforced plastic lining in the segment mould. A reduction in construction 

time thanks to the single pass installation of the tunnel lining with corrosion protection, 

as well as a reduced excavation diameter make this procedure interesting from an economical 

perspective. Conventional bolt connections with bolt pockets are no longer needed, since the 

segments are connected by special anchors. Furthermore, the especially smooth surface allows 

for an optimal sewer flow. 

The sewer tunnel was excavated with a Herrenknecht EPB machine (Ø 3,390mm). The 

machine quickly and precisely mastered working at a depth of more than 18 meters with a 

ground water pressure of 1.2 bar and crossing beneath a sewage pipeline at a distance of 

only 17 centimeters. 

The tunnel is designed to transport a total of 558,000 cubic meters of sewage water per 

day. Thanks to the Combisegment technology the pipeline is permanently protected against 

corrosion.

China visits the deep south 

The Trenchless Technology Center (TTC) at the Louisiana Tech University recently hosted leaders 

from China’s largest pipeline engineering firm – China Petroleum Pipeline Bureau (CPP). 

reSearch dIrecTOr fOr the ttC Erez 

Allouche said “this visit is another step in 

the strengthening of Us-China collaborative 

research in the area of trenchless 

technology and critical underground infrastructure 

issues, an initiative that is actively 

promoted by the Pipeline Division of the 

American society of Civil Engineering. 

“ttC representatives are scheduled 

to present two technical papers at the 

International Conference on Pipelines and 

trenchless technology to be held in Wuhan, 

China this fall, which will continue fostering 

our growing ties with China’s pipeline and 

utility construction industry. 

the delegation from CPP included its 

President Zhao Yujian, Assistant President 

Gao Zetao, Director of Foreign Affairs Ma 

Chunqing, Manager of Pipeline Inspection 

Cao Chongzhen, and Engineer – Foreign 

Affairs Zhang Yongxin. 

One of the group’s primary objectives was 

to find possible opportunities to build longterm 

technical and business co-operation 

with Louisiana tech and the ttC, especially 

as it pertains to trenchless technology 

applications in petroleum pipelines. 

IDS_high_res_HPH.pdf 25/2/09 9:48:58 AM 

“Our guests from China were impressed 

with the breadth of the underground technology 

being developed at Louisiana tech, 

as well as the scope of the ttC’s outreach,” 

said stan Napper, Dean of tech’s College 

of Engineering and science. “ttC faculty 

and staff are working directly with the cities 

of New York (a times square project), Los 

Angeles, san Francisco, Denver and many 

others as well as local projects with many 

cities in Louisiana.” 

During their visit, CPP leaders heard

Under singapore 

Singapore is a regional transcenter of excellence for water and wastewater 

management. Many successful rehabilitation and installation projects have 

been achieved through the use of Trenchless Technology. 

PubLIc uTILITIeS bOard (PUB) is 

a statutory board under the Ministry of 

the Environment and Water Resources. 

PUB manages the complete water cycle 

in singapore. It is the national water 

agency, managing singapore’s water 

supply, water catchment and used water 

in an integrated way. 

Director of PUB Water Reclamation 

Department tan thai Pin said singapore 

faces challenges as more lucrative 

land use competes with the need for 

urban water catchments. the solution is 

three pronged: 

• Membrane technology to filter 

sewer water 

• timely implementation 

• trenchless technology for pipe laying 

and rehabilitation. 

PUB plans to rehabilitate 1,000 km 

over the next five years using CIPP, spiral 

wound lining and fold and formed. they 

will also use pipe jacking and microtunnelling 

to extend the sewer network. 

Chief Executive of PUB Khoo teng 

Chye has said that singapore has come a 

long way from the days when it was faced 

with problems such as flooding, pollution 

and water shortages. since then, 

PUB has been recognised through many 

international awards. Mr Khoo attributes 

PUB’s achievement to investing in water 

restoration and development, technology 

and by adopting an integrated and holistic 

approach to water management. 

“today, we have in place a longterm 

water supply strategy known as the 

Four National taps, comprising water 

from local catchments, imported water, 

reclaimed water (branded NEWater in 

singapore) and desalinated water,” he 

said. 

Mr Khoo said that 

NEWater and desalinated 

water are the 

result of PUB’s 

c o n t i n u o u s 

PUB Water Reclamation Department 

Director Tan Thai Pin. 

“We engage the community, 

as well as the stakeholders, 

to conserve water, to value 

the water – so they don’t 

pollute the water – and also 

enjoy the water.” 

investments in R&D and technology. 

“By leveraging on advancements in 

technology and decreasing costs, PUB 

was able to successfully introduce these 

two alternatives as viable sources of 

water for singapore.” 

Mr Khoo has said that PUB has also 

worked towards a more people-oriented 

approach to delivering water, by adopting 

the tagline ‘Water for all: Conserve, 

Value, Enjoy.’ 

“securing an adequate supply of water 

is only half of the equation – managing 

the water demand is just as important. to 

ensure sustainability of singapore’s water 

resources, PUB calls on all singaporeans 

to play their part to conserve water, keep 

the water catchments and waterways 

clean and build a closer relationship with 

water by enjoying this precious resource.” 

Wastewater management 

PUB is vested with the challenging task 

of maintaining the sewerage reticulation 

system which has its origin in colonial 

times. the sewerage Department of PUB 

identifies older sewers, restores their condition 

and keeps the health of the system 

in the pink to serve the increasing development 

in singapore. 

ISTT Chairman Dec Downey. 

SgSTT shows leadership in 


In June 2010, Istt Chairman Dec 

Downey attended the launch of a 

local society to be known as sgstt. 

Dr Downey said that the singapore 

International Water Week was a great 

event with a number of international 

groups supported by their government 

and municipal agencies, good 

for networking and for promoting 

Istt’s singapore International No-Dig. 

“At one of the events, Minister Mentor 

Lee Kwan Yu, founder of the modern 

singapore spoke highly of the contribution 

of trenchless technology to 

the development of the clean, green 

singapore with its deep sewer tunnel 

and recycled water usage. Accolades 

which testify to the merits of our business 

do not come from sources any 

more esteemed than Mr Lee.” 

sewer rehabilitation originally involved 

a large amount of excavation work and 

sewers were repaired mainly by the open 

trench method. the operation, while necessary, 

was time-consuming and often 

caused inconvenience to customers. 

today, PUB uses a number of 

trenchless technologies such as pipe 

bursting and spiral wound lining in sewer 

rehabilitation work as they continue to 

maintain the 3,400 km of gravity sewers, 

220 km of pumping mains and 

130 pumping installations of the sewer 

reticulation system. 

PUB has also used trenchless 

technology to reline some 600 km of public 

sewers and private drain lines under 

the third phase of the ongoing sewer 

rehabilitation program. the trenchless 

technology used includes cure-in-place 

piping, spiral wound lining and fold-andform 

technology. 

the ongoing sewer rehabilitation program, 

current phase 2009–2014, will 

see the refurbishment 

of more than 

1,000 km of this 

network. Much of 

this work will be 

undertaken using 

microtunnelling. 

“Securing an adequate supply of water is only half of the 

equation – managing the water demand is just as important. 

When asked about the future use of 

trenchless technology in singapore, 

Mr Khoo said that PUB will continue to 

adopt the use of trenchless technology 

for the laying of sewers and for singapore’s 

ongoing sewer rehabilitation program. 

“this is to ensure that singapore’s 

sewer system is kept in tip-top condition 

and free of leakages that could contaminate 

our rainwater collection system.” 

deep Tunnel Sewerage System 

the Deep tunnel sewerage system, 

(Dtss) conceptualised and managed 

by PUB, is singapore’s superhighway 

to meet its used water needs for the 

next 100 years in a cost-effective and 

sustainable way. One of the world’s 

largest used water collection and treat- 

DTSS tunnel alignment 

ment projects, the Dtss conveys used 

water from homes and industries through a 48 km long deep tunnel sewer that runs 

20–55 m below ground to a centralised water reclamation plant 

for treatment. 

the major tunnelling challenges of the Dtss project included the high groundwater 

table; mixed face and very abrasive ground conditions; highly variable rock quality 

in the granite and sedimentary formations; and the major expressways directly 

above the tunnels, making avoidance of settlement and/or face collapse critical. 

the Dtss comprises a 48 km deep tunnel, a water reclamation plant, a deep sea 

outfall and some 60 km of linking sewers. Relying entirely on gravity, used water is 

channeled through the deep tunnel to the water reclamation plant where it is treated 

before being discharged to the sea. 

trenchless technology is being used in the construction of these deep tunnels 

and link sewers. the construction of the 48 km tunnels with diameters ranging from 

3.3 m to 6 m and depths of 18 m to 50 m below ground were completed using tunnel 

boring machines. 

A total of eight tunnel boring machines were used for driving the 48 km of tunnels. 

the eastern two-thirds of the North tunnel were constructed through the Old 

Alluvium layer, a generally competent tunnelling material. the tunnel however, 

was deep below the groundwater table, in some areas more than 45 m, requiring 

constant control of the tunnel face to prevent face instability. Earth-pressure balance 

shield machines were used to control face instability. the link sewers, with 

diameters up to 3 m and depths of up to 40 m are mainly being laid by pipe jacking. 

the Dtss was the recipient of the Global Water Awards ‘Water Project of the 

Year', the water project with the most significant contribution to water technology 

and environmental protection.

Report from singapore 

International water week 2010 

Singapore International Water Week 2010 ended on a high note for many local and international 

water companies, where the total value of announcements for projects awarded, tenders, 

investments into Singapore and R&D MoUs exceeded $US2.1 billion, up by 27 per cent from 

last year. The event, which was held together with the World Cities Summit this year, also saw a 

record increase in the number of trade attendees to over 14,000 from 85 countries/regions. 

MIchaeL TOh, MaNaGING Director 

of singapore International Water Week 

said “We are extremely pleased with the 

positive outcome at the 2010 singapore 

International Water Week which continues 

to grow into its third year. the continued 

strong support from participating countries 

and regions is an affirmation of our vision to 

be the global platform for water solutions. 

Despite the uncertain global economic 

recovery, water remains a key focus area 

for governments and industries as cities 

around the world continue to grow at an 

unprecedented rate with rapid urbanisation. 

Many countries continue to seek clean and 

affordable solutions to meet their respective 

needs and use the Water Week as a plat- 

form for learning, exchange and networking. 

We are delighted with the significant 

increase in the total value of announcements 

during the week. It augurs well for 

the growing water sector across the globe 

and in ensuring delivery of water services 

where needed." 

Demonstrating the event’s growing global 

appeal and significance, this year’s Water 

Week received strong support from the global 

community including the Istt. 

At the Water Convention, over 

1,000 experts, academics and practitioners 

came together to discuss the advancements 

and challenges in water technologies. 

In particular, the enhanced networking 

and business opportunities, such as the 

Industry-to-Industry networking sessions to 

enable cross industry interaction at the 

Water Week were well received as testified 

by the robust attendance at every session.

the story behind the pipe: 

an inside look at CIPP 

By Dec Downey, Chairman ISTT 

Cured-in-place-pipe (CIPP) has had an revolutionising effect on the world of 

infrastructure and asset management. Here Trenchless International looks at the 

history of the technology, how it was created, patented and its importance in the 

trenchless industry. 

accOrdING TO INduSTry legend, agricultural engineer Eric 

Wood was repairing a corrosion hole in an air duct on a mushroom 

farm when he conceived the concept behind CIPP – the use 

of fluid pressure to press the repair medium against the pipe wall 

whilst it cured in place to form a new pipe. 

Whatever the truth of that story, the fact is that Mr Wood, ably 

supported by entrepreneurs Doug Chick and Brain Chandler 

started an industry with a far-reaching effect on the infrastructure 

business, which has endured almost forty years. 

Wood, Chick and Chandler took the concept, sourced materials 

from resin producer scott Bader and felt maker WE Rawson 

and developed what we know as Insituform. they took the idea 

to the Greater London Council’s Metropolitan Water Board as a 

means to restore ageing water mains and were given the opportunity 

to demonstrate the efficacy of their method by lining a

100-year-old brick egg-shaped sewer at their own expense. 

In 1971 they impregnated a felt tube with polyester resin, 

wrapped in a plastic sheet, pulled the 70 m tube into the 

1,175.675 mm Marsh Lane sewer, inflated it and left it to cure. 

tested in 1991, after twenty years in service, it met the 4-34-04 

flexural modulus requirements – a research-based group of WRc 

– providing consultancy in the water, waste and environment 

sectors in the UK – by a margin of more than 20 per cent. this 

validated what many municipal engineers worldwide had already 

concluded: CIPP is here to stay. 

Wood, Chick and Chandler registered the company Insituform 

Pipes and structures Ltd (the first of many vehicles for patents 

and technology), and set about marketing their technology and 

developing improvements such as polymer coated felt and 

vacuum impregnation. 

they tried steam and UV curing too, but concentrated efforts on 

the time-proven water inversion and hot water cure system. 

By 1986, with licensed partners in the United Kingdom, they 

had completed over 400 projects for regional water authorities, 

municipal boroughs, power generators and commercial companies. 

As early as 1976 they lined pressure pipes, the first being a 

600 mm force main for thames Water in Reading. 

In the late 1970s they licensed various companies including 

Entrepose in France, Olimb in Norway, Per Aarsleff in Denmark, 

Monier in Australia and started a company in North America. With 

no shortage of entrepreneurship for Eric, Doug and Brian, they 

established Insituform North America Inc and Insituform Group 

Ltd in Guernsey as a royalty collector. 

these companies were floated on NAsDAQ, an American stock 

exchange, and the proceeds invested in R&D and tube making 

in Wellingborough and Memphis, tenessee. Both Insituform companies 

began to acquire back licensee businesses to vertically 

integrate and in 1991 merged to form Insituform technologies Inc. 

Strong patent protection 

this remarkable growth story was fostered by strong patent 

protection and some remarkably good licensed partners. But the 

protection afforded by patents is transient and long before the 

expiry of the first layers of protection others had noted the extraordinary 

growth of the business. 

In Japan in 1980, the tokyo and Osaka Gas Companies, 

with their contractors, developed hose lining systems using 

woven polyester hose and epoxy and polyester resins. By 

1983, PALtEM and Phoenix were well established and enhanced 

with felt for extra stiffness became used in water mains and sewers. 

Phoenix was licensed in France and switzerland and rapidly 

spread through Europe. Also in France, in the early 1980s the 

Copeflex process, a resin impregnated glass fibre liner developed 

by Coopetanche and subsequently acquired by sADE made 

inroads into the municipal sewer business. 

In Germany, the sewer maintenance group Kanal Muller, once 

sales agents for Insituform, developed and licensed a felt liner 

system, InLiner, which is installed using a calibration hose, and 

in sweden, Volmar Johnsson developed the glass fibre hose, UV 

light cured InPipe system. 

In the 1980s, with initial patents reaching maturity, many 

developers looked at the lucrative licensing route for taking their 

processes to market, and the multiple CIPP technologies spread 

to the far corners of the globe – Korea, New Zealand, taiwan, 

Venezuela and Argentina. Insituform, KMG and Ashimori, developers 

of PALtEM, set up in unlicensed territories. 

In the late 1980s, Insituform’s felt supplier WE Rawson established 

Applied Felts to service the needs of the many users of the 

basic felt and resin liner systems and other smaller felt liner makers 

were established in Europe and America. 

Prompted by the principles proven in the municipal market 

and the success of products such as the KMG Houseliner, other 

smaller contractors working with simple resin and felt systems 

began to work in local markets, servicing the needs of householders 

and other private sewer owners. 

the size of this market is hard to quantify but some measure 

of it is indicated by the UK Government’s decision to take about 

half the private sewer, some 200,000 km, into public ownership. 

In the UK, franchised sewer maintenance contractors groups 

such as DynoRod have seized on the opportunity and provide 

distribution for some of the smaller vendors who have focussed 

on this market. 

In the 1990s more UV light curing systems emerged in Europe 

with first Brandenburger, then BKP Berolina, saertex Multiliner 

and Impreg entering the fray. 

their impact has perhaps been influenced by the technical 

demands of the German market and the efforts of IKt, an independent 

test laboratory in promoting its facilities and research 

initiatives since about 2004. the annual performance tables of 

IKt have caught the attention of owners and specifiers and now a 

number of European contractors and municipalities are involved 

in a pan European testing scheme which annually ranks the performance 

of contractors. 

confidence in cIPP 

technical guidelines and standards play an important role in 

the acceptance and growth of technologies, particularly in the 

municipal infrastructure business. the role of WRc in developing 

its Manual of sewer Condition Classification and its sewer 

Rehabilitation Manual in 1983 cannot be understated. these 

together with the WRc Information and Guidance Note (Water 

Industry standard) 4-34-04 have influence the adoption of sewer 

rehabilitation techniques in general, and CIPP in particular, 

throughout the English-speaking world and beyond. 

the WRc Approval, an independent view on performance 

against accepted standards is also useful and many countries 

have similar systems. the Japan Institute for Wastewater 

Engineering technology is a particularly good example of a 

systematic evaluation program in the public interest. Following on 

from WIs 4-34-04 in 1985 came AtsM F1216 in 1979, EN 13566-4 

in 2002 and now IsO 11296 in 2009; all serve to build confidence 

in the CIPP concept but require that the utility owners and their 

contractors implement proper systems for product acceptance, 

quality control and assurance.

CIPP around the world 

Cured-in-place pipe or CIPP is a popular pipe rehabilitation method around the 

world. Here Trenchless International reviews a selection of current projects. 

CIPP creates a close-fit ‘pipe-within-a-pipe’ that has quantifiable structural 

strength and can be designed to suit various loading conditions. 

cIPP making tracks in Wiltshire 

A sewer dating back to the 1960s that 

runs alongside the Bristol to London railway 

line in the UK was recently repaired 

using CIPP. the ageing asbestos concrete 

(AC) sewer, operated by Wessex Water, 

had suffered a number of fractures and 

was relined using CIPP to safeguard it for 

the future. 

A CCtV investigation of the 650 m long 

sewer revealed that it had lost structural 

strength and sections exposed to the elements 

had caused exfoliation of the outside 

surface leading to a number of ring fractures 

– a common problem for AC sewers. 

Critical sewers team senior Engineer 

Julian Britton said repairing the 375 mm 

diameter sewer in Corsham, Wiltshire, 

using trenchless technology had 

many advantages. 

Mr Britton said “Without the use of this 

technology it would have been impossible 

to repair the sewer without closing this 

busy section of railway line which would 

have been extremely disruptive and costly. 

“In addition, it meant that we could safely 

make improvements to support the pipe’s 

structure without the risk of compromising 

the asbestos cement pipe’s integrity.” 

Once the cleaning was complete, the 

sewer was relined in two shots using liners 

measuring 325 m and 323 m. 

cIPP in Singapore 

In 2009, Public Utility Board (PUB), 

singapore’s publicly-owned water utility, 

began work on a multi-year $Us295 million 

rehabilitation program. this rehabilitation 

program is expected to be completed in 

2014 and will upgrade over 700 miles of 

public sewers and 30 miles of pumping 

mains. PUB serves a population of over 

4.5 million singaporeans. these contracts 

are part of PUB’s ongoing rehabilitation 

program. 

Relining company Insituform 

technologies singapore subsidiary, Insitu 

Envirotech, has been awarded four contracts 

totalling $Us18.5 million. Under the 

contracts, Insituform will perform work for 

the PUB, and rehabilitate approximately 

50 miles of sewer pipeline though the use 

of the CIPP process. 

Insituform’s Vice-President Asia-Pacific 

Daniel Cowan said “Insituform looks forward 

to continuing its work with PUB and 

to the opportunity to bid on additional work 

as PUB continues its ongoing rehabilitation 

program. In addition, we continue to 

provide enhanced services to the market 

in singapore by supplying local rehabilitation 

contractors with our CIPP tube. We 

expect to continue this offering by supplying 

CIPP tubes for PUB projects for many 

years to come. 

“singapore’s PUB is one of the most 

progressive water utilities in the world. 

With this project, which is Phase IV in its 

overall sewer rehabilitation program...PUB 

will be able to upgrade its system with little 

disruption to the people of singapore,” 

said Mr Cowan. 

a record-breaking installation in 

helsinki 

the Olympic stadium in Helsinki, 

Finland, the location of the 1952 summer 

Olympics, is undergoing a major renovation. 

One challenge was the vertical 

rainwater pipes in the 72 m Olympic tower. 

Making changes to the structure of the 

tower is prohibited, and contractors were 

not allowed to excavate, so no new pipes 

could be installed. As well as the rainwater 

pipes, the outlets and connections were 

also in very bad shape. 

the Public Works Department contacted 

Aarsleff Oy and asked if Aarsleff 

CIPP Lining could be the solution. the 

company said “We were honoured to be 

asked to work in one of the most wellknown 

landmarks in Helsinki.” 

After careful planning and calculation, 

Aarsleff Oy came to the conclusion that 

Aarsleff CIPP Lining could be installed 

in one 72 m stretch. the pipelines were 

cleaned, the side connections were 

installed, and the liners went up to the 

top of the tower as planned. Including all 

the preparation works, the job took only 

four days. 

“so we can say it was a perfect job and 

a record-breaking installation altogether,” 

said the company.

CIPP Lining 

completed the CIPP relining of over 

650 m of oviform sewer pipes through 

Perth’s city centre. 

the project, commissioned by the 

Water Corporation, called for the rehabilitation 

of the gravity-fed sewer system 

along st Georges terrace, the only road 

that bisects the city centre east to west 

without interruption. 

the challenge was to complete the 

works with minimal disruption to the flow 

of traffic, while maintaining the integrity of 

the reline. the works program called for 

the CIPP relining of 650 m of gravity-fed 

sewers to be broken into seven portions, 

each portion including jet washing, 

pre-and post-reline CCtV surveys, reinstatement 

of junctions and refurbishment 

of the access chambers. 

the project was further complicated by 

the need to access, monitor and King Vac 

(vacuum recovery) the private pumping 

stations servicing each of the office buildings 

along st Georges terrace during the 

bypass periods, including Perth’s largest 

building Central Park. Drilline liaised 

with building management for each of 

the buildings prior to the commencement 

of the project and in the lead up to 

each new section. Working at night and 

weekends did reduce the flow, resulting 

in reduced risk to Drilline personnel and 

other stakeholders in the bypass component 

of the project. 

Drilline successfully completed the

CIPP 


October 2010 - Trenchless International CIPP 

32 

CIPP chosen to achieve 

global expansion 

Oilfield construction company DFI Corporation, recognising the growth in the trenchless industry, has 

chosen CIPP technology as a way to expand its business. DFI is using RS Technik’s cured-in-place pipe 

installation systems, which give businesses both timing and geographical flexibility, allowing them to 

undertake rapid repairs in any conditions. 

SINce 1966, dfI Corporation has supplied 

the oilfield construction industry with 

pile-driving, pile supply and trucking services. 

However, the seasonal nature of the 

oil and gas industry means that projects 

are not balanced throughout the year. 

DFI General Manager sean Freeland 

says “For the past few years we’ve wanted 

to diversify. 

“When the oil business is good, it’s very 

good. But we needed more consistency, 

the ability to expand into a business that is 

outside of oil and gas – also one that is of 

an opposing season so that we can blend 

crews and maximise work hours throughout 

the year.” 

“One of my employees brought to my 

attention cured-in-place pipe (CIPP) for 

the repair of mainline sewer pipes,” says 

Mr Freeland. 

“While this work happens all year, it is 

more common to reline pipes in the spring 

and summer seasons, while oil and gas 

work typically happens in the fall and 

winter. so we quickly realised that CIPP 

was a perfect complement to our existing 

business model.” 

Incorporating CIPP into the business 

also allowed DFI to grow geographically. 

“the possibility of enhancing our expansion 

into the United states and beyond 

was very appealing to us. By reducing our 

vulnerability to local recessions and other 

economic concerns, CIPP provides us a 

certain security” says Mr Freeland. 

DFI’s management then had to 

determine the most effective way to 

enter the CIPP market. Following thorough 

research into the CIPP industry, 

DFI chose Rs technik, which offers the 

Rs CityLiner system for mainline rehabilitation 

and repair. 

“We looked at everybody before deciding 

to go with Rs technik,” Mr Freeland 

said. “they were the most advanced in 

terms of research and development, and 

they had proven their systems in Europe 

and other areas around the world for more 

than 15 years.” 

the Rs CityLiner systems provide 

unparalleled logistical advantages in 

“find and fix”, emergency work and the 

multiple mobilisations common in maintenance 

contracts. the systems have the 

ability to prepare, impregnate and install 

DOW formulated epoxy liners right on 

the job site, enabling rapid response to 

needed repairs. 

Rs technik’s Joanne Hughes says “Our 

exclusive, on-board computerised feature 

allows full visibility to project inspectors 

from wet-out through installation. In spite of 

ever-changing environmental conditions, 

our automated systems ensure that jobs 

are done right the first time.” 

Mr Freeland says that the Rs CityLiner 

system has two key stand-out features: 

“the number one feature that comes to 

mind is that the Rs CityLiner system only 

uses DOW formulated styrene-free epoxy

resins,” he says. “the fact that the system 

is environmentally friendly is a huge benefit 

to us. 

“the other main reason we went with the 

Rs CityLiner system is the mobile nature 

of the unit, and the fact that everything 

we need – equipment, materials, even the 

wet-out function – is right onboard.” 

Mr Freeland also says that he invested 

in the Rs CityLiner system because it was 

clear to see where Rs technik is headed. 

“they are extremely progressive,” he says. 

“they are continually working on different 

styles of liners, equipment and technology 

developments that will improve and 

expand the system solutions even more.” 

In a recent visit to Europe, Mr Freeland 

and his team experienced Rs technik’s 

comprehensive, in-the-field training. 

“We saw several job sites, all with different 

conditions. We left with a clear idea 

of what to expect, and what’s expected of 

us in order to be effective in the field and 

delivery quality work for our customers.” 

With a desire to be a full-service provider 

as quickly as possible, Mr Freeland 

is considering the MaxLiner system, which 

means he will also be able to offer lateral 

CIPP repair services. 

“Including CIPP into our service offering 

is load-levelling. We will now have consistent 

business throughout the year, and with 

Rs technik’s support, we believe we can 

be the first-responder, no matter where in 

the world the business leads us.”

A 1.8 m diameter Robbins Rockhead is 

boring an unprecedented seven sewer 

tunnels in Ohio, US. 

Robbins rocks through seven 

Indiana, US contractor Midwest Mole Inc had a daunting task ahead of them when they were 

named General Contractors for not one, but seven sewer tunnels, tackling the unprecedented 

bores with Robbins Rockhead. 

WITh each TuNNeL varying in grade and 

the route travelling through interbedded layers 

of shale and limestone, ranging from dry 

conditions to wet, sticky ground. 

Despite the highly changeable conditions, 

Midwest Mole chose a single machine 

solution for the pipeline, totaling 2,874 m 

in length. 

the contractor is utilising a 1.8 m diameter 

Robbins Double shield Rockhead to excavate 

the tunnels, ranging from 249 – 614 m 

long, for the shayler Run segment C sewer 

Replacement Project in Clermont County, 

Ohio, Us. the $Us15 million project will 

upgrade severely degraded sewer systems 

and protect the area surrounding environmentally-sensitive 

shayler Creek. 

Project background 

the shayler Run segment C project is a 

priority for the project owner, the Clermont 

County, Ohio Water Resources Department, 

because of severe pipeline erosion in the 

creek bed. 

sanitation Engineer for the Clermont 

County, Ohio Water Resources Department 

Lyle Bloom said “the existing sewer pipe 

was installed in 1978 directly into the creek. 

since then, the creek has eroded, exposing 

the pipe to the environment and putting 

certain sections at high risk of failure. the 

exposed pipe has now dumped raw sewage 

into the creek on several occasions.” 

the new pipeline will be installed well below 

the creek bed, crossing the creek a total of 

seven times. the route cover ranges from 3 to 

30 m, with the majority of the pipeline running 

some distance from the waterway. 

Final carrier pipe will consist of 1 m 

diameter HOBAs reline, and will be much 

larger than the current 600 mm sewer line. 

“the larger pipe was decided on mainly 

to allow trenchless construction, though it 

has the added benefit of providing a larger 

capacity for future needs in the area,” said 

Mr Bloom. 

Pipeline construction consists of seven 

tunnels criss-crossing the creek, each connected 

by a 9.7 m diameter launch and 

receiving shaft, with a total of eight shafts 

in all. the shafts will eventually become 

fiberglass manhole structures to access the 

new pipeline. 

Due to the gravity sewer construction, 

each tunnel is at a slightly different grade to 

maintain specified slope. 

Vice President of Operations at Midwest 

Mole steve Abernathy said “We needed 

a machine that could hit the specified 

manhole locations within a foot of line at 

1.3 – 2 per cent grade.” 

choosing the machine 

the nature of the extensive gravity 

sewer made the machine selection all the 

more challenging. 

The Robbins Double Shield Rockhead 

completed its first of seven tunnels at rates 

of up to 32 m in 24 hours. 

The Robbins Double Shield Rockhead is 

boring and installing a primary liner of steel 

ring beams and lagging every 1.5 m. 

US Contractor Midwest Mole is boring seven 

sewer tunnels to upgrade severely corroded 

lines in environmentally-sensitive Shayler 

Creek.

The Robbins Double Shield Rockhead is steered continuously from an in-shield operator’s console. 

The Robbins Rockhead is excavating the first 

900 m with a mixed ground cutterhead for 

soft shale and limestone, before switching to 

a hard rock cutterhead. 

the seven tunnels, with their varying 

grades, result in a change of 

54 vertical metres over the course of the 

project. As a result of the elevation change, 

the tunnels travel through different strata 

consisting of softer shale and limestone for 

the first 900 m, changing to harder, drier 

shale and limestone for the later tunnels. 

to effectively excavate in the conditions, 

Midwest Mole needed a solution to excavate 

mixed ground as well as hard rock up to 

165 MPa UCs. 

“the Rockhead was the best suited to the 

project conditions based on our previous 

experience with similar Robbins machines. 

two-pass tunnelling with a Double shield 

Rockhead was also more cost effective 

than microtunnelling when we prepared our 

estimates,” said Mr Abernathy. 

the original contract allowed for either 

microtunnelling or two-pass tunnelling, 

which allows for installation of a primary 

liner before placing the carrier pipe. 

the Double shield Rockhead was 

designed with a mixed ground cutterhead 

that can be changed out for a hard rock 

cutterhead later on. the mixed ground cutterhead 

features 6.5 inch single disc cutters 

and carbide bits, combined with large 

openings in the cutterhead to ingest mixed 

ground and to allow for cutter changes. 

the hard rock cutterhead is dressed 

with 11.5 inch diameter single disc cutters 

and abrasion-resistant muck scrapers, as 

well as a cutterhead opening for cutter 

changes. Crews will switch out the cutterhead 

between crossings in one of the 

launch/receiving shafts. 

how it works 

the Robbins Double shield Rockhead 

(sBU-RHDs) is a tunnelling machine for use 

on longer utility installations, usually over 

180 m, in unstable ground. It is also typically 

used for line and grade-critical installations 

such as gravity sewers, as the machine can 

be continuously steered from an in-shield 

operator’s console. Line and grade are 

monitored continuously using a laser targeting 

system. 

the machine, available in diameters from 

1.3 to 2 m, consists of a circular cutterhead 

optimised for either mixed ground or hard 

rock. Hard rock disc cutters are capable of 

excavating ground ranging from 25 to over 

175 MPa UCs. 

As the cutterhead rotates, disc cutters 

penetrate the rock face and create a ‘crush 

zone’ through which fractures propagate. 

Material between adjacent crush zones is 

then chipped from the rock face. 

Muck scrapers scoop the muck into 

openings on the cutterhead called muck 

buckets, which transfer the material to a 

machine belt conveyor. Muck removal from 

the site is by either a belt conveyor or 

muck cars. 

crossing excavation 

Excavation of the first tunnel began on 

19 May 2010, from an 11 m deep shaft. 

the Robbins Rockhead completed its first 

474 m long drive in three months, holing 

through on 18 August into a shaft site. 

“the mixed ground cutterhead is ideal for 

the ground. After 474 m there is almost no 

perceptible wear of the teeth or disc cutters. 

the machine also drives very smoothly and 

has plenty of power for these conditions,” 

said Mr Abernathy. 

Crews reported advance rates averaging 

150 mm per minute in low strength 

shale using the mixed ground cutterhead. 

Advance rates topped out at 32 m in 

24 hours, or 21 1.5 m long ring beam and 

board sets in two ten-hour shifts. the swift 

advance comes despite some unforeseen 

difficulties, including a section directly below 

the creek bed with significant groundwater, 

and gripper slippage in the soft, wet ground 

during machine pushes. 

the machine was launched from its 

receiving shaft to bore a second 575 m 

long tunnel on 30 August, following some 

maintenance and modifications. Changes 

included modifying the hydraulic system 

for increased gripper and roll correction 

cylinder pressure. the increases allowed 

the machine to grip and roll correct in the 

extremely soft, often wet rock. 

As the machine bores, a primary liner of 

ring beams and lagging is set every 1.5 m. 

After each ring is built, a muck train consisting 

of a battery-operated locomotive and 

three muck cars removes spoils from the 

tunnel. the muck will be used as back-fill 

around some of the shaft sites after project 

completion, and potentially as fill on private 

property in the area. 

Work on the launch/receiving shafts is 

ongoing – four shafts are now complete 

using a combination of drill and blast techniques 

and manual excavation. some open 

cut pipe jacking operations are also connecting 

existing, peripheral lines to the new 

sewer line. 

Midwest Mole recently utilised a 

760 mm diameter Robbins sBU-A for a 

46 m long crossing of the creek, which will 

connect a 460 mm diameter PVC sewer to 

the main line. 

the work to date has been successful, 

in large part due to teamwork between 

Midwest Mole, Robbins field service, and 

the project owner. 

“If there is one thing we would like to 

emphasise, it would be how willing the contractor 

has been to work with us throughout 

the project. In addition to proposing the 

tunnelling method, they planned value 

engineering that resulted in substantial 

cost savings,” said Mr Bloom. 

“When the project was bid, there were 

originally eleven shafts, but Midwest Mole 

proposed to eliminate three shafts. they 

obtained easement rights to alter the project 

alignment, and shortened the project schedule 

with their new plan.” 

All seven of the tunnels and the eight 

manhole shafts are expected to be completed 

by May 2012.

Borouge pipes up to 

help China’s eco city 

Borouge’s new high stress crack-resistant BorSafe PE100 material is specifically developed for 

installation in difficult conditions. It was put to the test in China’s new eco city in Tianjin, where a much 

needed new water supply pipeline had to pass under a canal. 

bOrOuGe IS a market leader in pipe 

solutions for drinking water and sanitation, 

gas distribution and industrial applications 

and domestic heating and cooling 

systems. 

A leading provider of innovative and 

value-creating plastics solutions, Borouge 

is providing advanced materials for pipe 

systems that require easy installation and 

superior durability. 

Borouge Vice President for Business 

Pipe Unit Hu Wei said “By using pipe 

produced from our new high stress crack 

resistant PE100 grade, the local water 

company was confident to install the pipe 

under the canal using directional drilling, 

knowing that any surface damage would 

not reduce the life of the pipe. 

“Our commitment to working with partners 

throughout the value chain ensured 

the ideal materials were being used for the 

different sections of the pipelines.” 

the project was to supply water to 

a city which is taking shape in China’s 

tianjin Binhai New Area, situated 45 km 

from tianjin and 150 km from Beijing. 

It is the tianjin eco city which is being 

jointly developed by the Chinese and 

singaporean governments. the total area 

is over 30 sq km and the city expects to 

have 350,000 residents by 2020. 

One major challenge for the developers 

was that the existing water supply did 

not match the current demand, let alone 

the future requirements of the city. A 

new water supply line was commissioned 

with a total length of 4.5 km, starting at a 

point 80 m to the west of Jingshan railway 

and then following the left bank of the 

Yongding New River, passing under the 

Ji Canal, and then to the pumping station 

which will provide the water to the 

eco city. 

since the pipeline needed to be 

installed as quickly as possible to prevent 

the construction work being constrained, 

the tianjin tEDA water company was 

keen to use polyethylene (PE) pipe to 

increase the speed of installation. 

However they were very concerned that 

the section under the Ji Canal, to be 

installed by directional drilling, could

sustain considerable surface damage 

from stones or other hard materials in the 

soil under the canal bed as the pipe was 

drawn into position behind the drill head. 

to allay their concerns, pipe manufacturer 

Cangzhou Mingzhu Plastics, supported 

by Borouge, was able to offer pipe manufactured 

from the new PE100 high stress 

crack-resistant material. 

Borsafe HE3490-Ls-H was specified for 

this section of pipeline as it is extremely 

tough and will resist the development of 

cracks and damage that may be caused 

during the directional drilling operation. 

the remainder of the pipeline was 

manufactured from the standard Borsafe 

HE3490-Ls Black PE100 compound. All 

the pipes were manufactured by the well 

known local pipe producer Cangzhou 

Mingzhu Plastic Co. Ltd that is part of 

the Hebei Cangzhou Dongsu Group and 

the project was successfully completed 

on schedule.

Piloting to success in jacksonville 

by Stephen Tait 

Mears Group, Inc. recently completed a 7,400 foot horizontal directional drilling (HDD) bore 

in Jacksonville, Florida, US, a design-build project that allows a regional energy producer to 

expand its natural gas pipeline to serve new facilities. 

TO cOMPLeTe The project, Mears 

drilled a 7,400 foot pilot hole beneath 

the st Johns River at a depth of 

130 feet below river bottom to install the 

16 inch steel pipe. It is an essential link in a 

50 mile pipeline that ends at the 

Jacksonville Electric Authority (JEA) 

Greenland Energy Center. 

though just 1.4 miles of the 50 mile 

pipeline, which is owned by tECO 

Peoples Gas, the section under the st. 

John’s River proved the most daunting in 

planning stages. 

Director of Engineering for tECO 

Peoples Gas Mark Haney said “this was 

the biggest obstacle to go from one side 

to the other.” 

HDD was virtually the only option to 

install the pipeline through that area. Mr 

Haney said “Other than HDD, there were 

no other good options.” 

But project officials said the timing of 

the project was also a major issue. 

Mr Haney said that the pipeline providing 

service to the power plant will 

be operational by 1 January 2011. that 

means JEA was dependent on the pipeline 

being in place in time to move 

forward on the operation of the power 

plant. to help ensure a timely project, 

The Mears rig in action. 

tECO hired Mears to complete a designbuild 

project. 

Project Manager for J.R. Giese 

Operations–Mears’ sub-consultant–John 

Fluharty said “If it is not built on time you 

literally have a billion dollar power plant 

there with no fuel.” 

Mr Fluharty said design-build allowed 

Mears to drill a pilot hole months in 

advance to pulling product pipe to ensure 

the project was feasible. 

“tECO wanted to know that early 

enough in the process so they would 

know if they needed to go in another 

direction, and wanted a true partnership 

put together so they could work out all the 

issues related to this special feasibility 

hole we did in advance,” Mr Fluharty said. 

Design-build is relatively new to the 

HDD industry, Mr Fluharty said. 

Design-build offers a subtle but important 

difference from the typical procedure 

for HDD projects. In the typical process, 

a company such as tECO would hire an 

engineer to develop plans, procure a 

construction company to implement those 

plans and then construct the project 

– often called design-bid-build. Designbid-build 

requires multiple contracts. 

With design-build, however, a single 

company is hired to engineer and to build 

the project, all under a single contract. 

susan Hines of the Design-Build 

Institute of America says utilising designbid-build 

can create contention between 

the engineer or designer of a project and 

the company that constructs the project. 

she said it creates a disconnect between 

the two parties that can often turn contentious 

because of concerns of liability 

and litigation. 

For instance, Ms Hines said when the 

construction company finds changes 

need to be made to designs during 

“Other than HDD, there were 

no other good options.” 

construction, it takes paper work and 

dialogue for the changes to be approved 

and implemented. 

“It slows things down a lot,” Ms 

Hines said. 

In the end, design-build projects help 

to improve two important aspects of any 

project – money and time. 

Design-build projects cost at least 6 per 

cent less than design-bid-build projects 

and are constructed 12 per cent faster, 

according to the Design-Build Institute of 

America. At the same time, the institute 

reports that design-build projects earned 

the highest owner satisfaction than other 

project concepts. 

“One of the main advantages of designbuild 

is the fact that everyone on the 

design and construction job is on the 

same side,” Ms Hines said. “they are all 

sharing in the risks and the rewards of a 

job well done.” 

she added, “Owners save money, they 

save time.” 

Mears drilled the feasibility pilot hole for 

the project in November 2009 and product 

pipe was pulled in April 2010. 

Mears Project superintendent Mike 

Maxwell said the crew drilled from both 

sides of the st Johns River and intersected 

the two holes under the river – a waterway 

lined with stately homes and used mostly 

for recreational purposes. 

A 330,000 pound rig was used for the 

pilot hole on one side of the river and a 

140,000 pound rig was used to drill from 

the opposite side. 

Mears utilised its 500,000 pound 

rig to perform the reaming and to pull 

the product pipe through the hole, Mr 

Maxwell said. 

Additionally, Mr Maxwell said, the crews 

reamed the bore to 24 inch diameter and 

then swabbed the hole before pulling the 

product pipe. the crew drilled through 

sandy silt before making it to clay for the 

drill’s running depth. 

“It was fairly easy going; we were able 

to use a jetting bit all the way through,” Mr 

Maxwell said. 

Mr Maxwell said the length of the drill 

combined with the unique aspects of the 

job, made it a satisfying accomplishment.

jacking the Blue Lagoon 

Hobas’ CC-GRP jacking pressure pipes are part of Venice’s major environmental plan to 

help reduce and prevent future pollution to the world’s famous Blue Lagoon. 

The LaGOON Of Venice is the largest 

in Italy and is situated between the drainage 

basin of the mainland and the sea. 

It has been subjected to more and more 

pollution due to increasing industrial and 

agricultural developments in the region. 

In 2000, the Regional Government of 

Veneto set up a master plan to prevent further 

pollution and treat the water running 

from the basin into the lagoon. the project 

Fusina forms the main part of the planned 

efforts and ranks regarding its extent and 

integral approach concerning wastewater 

treatment and environmental protection 

among the first in Europe. 

Within the bounds of this project, the 

existing treatment plant in Fusina is transformed 

into a ‘multipurpose facility’ that 

purifies sanitary sewage and stormwater

of Mestre, Marghera and Mirese–which 

together has approximately 350,000 inhabitants, 

industrial effluents and polluted 

groundwater from the Marghera harbor. 

In order to optimise the treatment, the 

new plant collects sewage separately and 

according to the following scheme: 

• sewage type A: sanitary sewage and 

stormwater from Mestre, Marghera and 

17 towns in the region Mirese 

• sewage type B1: Industrial effluents 

from the Marghera port basin 

• sewage type B2: stormwater and 

sullage 

• sewage type B3: Polluted groundwater. 

type A sewage is biologically treated 

with ultrafiltration membranes and consequently 

phytodepuration. the latter is 

conducted on an area of around 15 hectares 

where the water is purified through 

metabolic processes of nymphae (water 

lilies) and other water plants. Walks and 

bikeways were built between the naturalistic 

water lanes to make the area 

attractive also for recreation. Instead of 

daily diverting 75 m³ of water from the 

river sile, the treated water is used by 

local industries and for cooling water in 

petrochemical plants.

strength and optimal hydraulic

systems would have been utilised to 

match all requirements.”

the leak-tight pipe system with its 

high performance couplings is produced 

to withstand an operating pressure of 

6 to 10 bar. the very smooth outer surface 

of the pipes enabled comparably 

low jacking forces and allowed a single 

jack over the complete section of 351 m. 

Only the starting and receiving pit were 

used saving on three originally planned 

intermediate stations. 

thanks to the use of a microtunnel boring 

machine drill head with a hydraulic soil 

removal system and the smooth surface 

of HOBAs CC-GRP Pipes the line was 

installed within less than a month. the 

extremely small roughness co-efficient 

of the inner liner of the pipes and the, 

comparatively light wall construction 

reduced the volume of excavated material 

considerably keeping costs to a 

minimum and making the installation a 

complete success.

jack in the box 

by James Thomson, Chairman, Jacked Structures SA 

James Thomson, owner and principal of Jason Consultants Group until 2003, recently formed 

Jacked Structures SA. Here Mr Thomson details the different concepts of installation. 

The JackING Of large structures, 

such as road underpasses, pedestrian 

subways and culverts uses trenchless 

jacking methods. 

I developed and pioneered these techniques 

in the 1960s and 1970s when 

working with a major international contractor. 

the initial projects were for pedestrian 

subways using large diameter pipes to 

provide the structure. the next development 

was to jack box sections for culverts 

and pedestrian subways. With this experience 

we increased the dimensions to 

accommodate larger structures. Figure 

1 illustrates a typical situation where a 

pedestrian subway is driven under a rail 

embankment to allow separation of traffic 

and pedestrians. 

Figure 1 A Pedestrian subway under rail 

embankment. 

the most basic approach, which is still 

widely used, is box jacking where the 

structure is constructed on a launch pad 

adjacent to where it is to be installed and 

is jacked into the ground with excavation 

taking place in the shield. 

Dealing with a face excavation which 

can be typically 15 m wide and 8 m 

high you need to compartmentalise the 

shield, which is fixed to the front of the 

structure – very much like Brunel’s shield 

for the very first tunnel under the thames 

back in 1823. You also need to provide 

thousands of tonnes of jacking capability 

to push such large sections, which in 

turn needs the provision of suitable reaction. 

the frictional loads on a rectangular 

structure are much greater than experienced 

when installing circular sections 

so there is a need to introduce anti-drag 

systems to reduce this. 

Many installations have been undertaken 

under roads, rail tracks and 

runways. Figure 2 shows one of the 

first projects undertaken in the early 

1970s where two underpasses were 

driven below a major road in North 

London to provide access to Brent Cross 

shopping centre. Perhaps the most high 

profile installation was the three large 

underpasses jacked under rail tracks in 

Boston, Us as part of the Big Dig project. 

these boxes were approximately 24 m 

wide, by 11 m high and the longest drive 

was 109 m. Figure 3 gives some idea 

of their size and the large number of 

hydraulic rams that were used. Because 

of the ground conditions – which were 

mainly soft marine deposits with old piles 

and buried quay walls – the ground was 

stabilised by freezing. 

Figure 2 Brent Cross jacked Underpass 

under A41. 

Figure 3 Jacked Boxes Boston Big Dig. 

Box jacking, where the track is temporarily 

supported and structures are 

installed directly below the rail tracks, is 

widely used in Europe. 

there are some inherent limitations in 

box jacking and in recognition alternatives 

approaches have been developed. 

If provision is made with the rail authority, 

it is possible to obtain brief possession 

to undertake work. With this in mind I 

developed the modular approach. 

Using a series of precast jacked boxes, 

abutments and central piers can be 

constructed without disrupting rail operations. 

As can be seen, a whole series of 

operations can be undertaken from the 

boxes such as cross strutting and finally 

stressing the boxes together and infilling 

with concrete. During a short track 

possession the bridge deck can be slid 

in or bridge beams placed to complete 

the structure. A large number of such 

jobs have been undertaken in the UK. 

A typical installation is the Wandsworth 

under-bridge shown at figure 4. this 

concept minimises the exposed face at 

any time and requires much less launch 

area as only relatively small jacking pits 

are needed. 

Figure 4 Wandsworth Under-Bridge 

London. 

More recently a new patented development 

is the jacked deck which can 

be combined with the modular system to 

provide a complete structure without disrupting 

rail services. the modular system is 

used but the top box is modified internally 

to allow a slide track to be installed. these 

top boxes are also designed with a removable 

section which exposes the track as the 

deck is jacked into place. the jacked deck, 

which can be formed from a complete cast 

on site structure or formed from precast 

beams, is fitted with a compartmentalised 

shield where excavation takes place. this 

same concept can also be used with a 

jacked circular tube or box providing an 

access gallery which allows piling to be 

undertaken to provide abutment walls and 

the installation of the slide track. 

this approach is currently being used 

to install a 20 m wide by 126 m long traffic 

underpass under rail tracks in UK. 

Another patented approach is to install

cities is creating a demand 

to install structures below 

existing facilities and 

buildings. The potential 

applications for creating 

large underground spaces 

by jacked methods without 

disruption are unlimited. 

initially jacked foundation boxes with 

removable lids and install in these boxes a 

slide track. In this case, precast arch sections 

are jacked in along the track with lids 

being removed within the shield as excavation 

takes place. 

the Jacked Arch has a number of advantages 

such as the reduction of jacking loads 

and face stability is improved. the use of 

precast arch sections also minimises the 

launch area. this approach enables larger 

spans and longer length to be installed. 

Metro station structures are quite possible 

and full support to the excavation as work 

advances would be provided thereby eliminating 

the risk of collapse. 

there are other techniques used such as 

the provision of advanced support structures 

where a canopy is installed as an 

initial support for the final structure. typical 

approaches are shown in the graphic 

at figure 5. the steel tubes that form the 

canopy can be installed by pipe ramming, 

microtunnelling or auger boring. 

Figure 5 Advanced support structures. 

Although the majority of Jacked structure 

installations have been in Europe, projects 

have been undertaken in Us, India, 

Canada, south Africa, Indonesia, taiwan, 

Korea, Japan and Australia. 

the relentless growth of cities is creating 

a demand to install structures below existing 

facilities and buildings. the potential 

applications for creating large underground 

spaces by jacked methods without disruption 

are unlimited. the separation of road 

and pedestrian traffic from rail traffic is 

essential to avoid the all too frequent accidents 

that occur at rail crossings. Valuable 

and scarce development land cut off by 

rail tracks and highways can be accessed. 

New underground space such as parking 

garages and storage can be created. 

One interesting possibility that was put 

to me in Australia was the possibility of 

installing wine storage caverns. I am hoping 

this will go ahead and I might get the 

opportunity to check out the quality of 

wine stored.

the latest in pipe and 

cable locator technology 

by Anthony Johnstone, Access Detection 

The traditional locator has been around in one form or another for over 100 years. Although 

there have been many advancements with the humble pipe and cable locator they still work 

on the same principles of the first locators ever built. Here, Australian supplier Anthony 

Johnson from Access Detection reports on the latest developments from the region. 

aLL LOcaTOrS haVe some form of 

antenna internally; this internal antenna 

picks up the electromagnetic field that 

radiates from conductive pipes or cables. 

the very basic locator has one horizontally 

or vertically mounted antenna. 

these units are unable to give depth 

electronically but are still able to give 

depth by a passive means, for example 

a null unit can give you a general depth 

via a method called triangulation. the 

common split boxes were very popular 

in early days for many good reasons: 

they taught the locator operator to locate; 

they usually had a high frequency, which 

helped locate the basic services easily; 

and, they were very simple to use. talk to 

a professional locator operator and they 

will usually have an old split box in the 

back of their van for back-up on those 

unique jobs where this type of unit worked 

well. Unfortunately most of these units 

are showing their age in technology and 

can struggle in congested areas. there 

is still a market for these types of units for 

councils, water authorities and excavation 

companies who only need to locate the 

basic services and some manufacturers 

are releasing more updated versions of 

this technology which will offer lower costs 

and ease of use. 

today’s more advanced locators offer 

faster processing power, can do more 

things at once and offer multiple antennae. 

All this technology, if done right, 

can offer the operator a simple machine 

to use while still giving good performance 

in more demanding locates. But be 

warned – all this advanced technology 

does have its drawbacks. 

Processing power 

Units these days offer high-powered 

processing speeds, while some even offer 

Locators on display. 

multiple cores. One of the advantages of 

this new processing power is the ability 

of these machines to do two things at 

once; for example locators may be able 

to show depth while still in locate mode, 

which eliminates the need to press the 

depth button as the depth is displayed 

when nearing the maximum centre of the 

magnetic field. some experienced users 

dislike this feature as they feel it takes 

control away from the operator. It may also 

give the more inexperienced operator a 

false belief that the depth will be correct 

without doing the correct checks. 

Multiple frequencies 

How many frequencies do you need 

on your locator? 95 per cent of the time a 

maximum of four frequencies is more than 

enough as long as they provide a large 

spread – for example a low frequency 

between 512 Hz and 1 kHz, a medium 

frequency between 4 kHz to 8 kHz, a 

medium to high frequency from 28 kHz 

to 65 kHz and a higher frequency above 

65 kHz to 200 kHz. 

Remember owning the latest equipment 

can have its disadvantages as it 

has not been tested for reliability infield 

and like so many new products these 

days you usually become the guinea 

pig and have to put up with glitches in 

software and hardware; this is the price 

you pay for being the first to purchase. 

Over time the manufacturers do normally 

get things right but at the expense of the 

frustrated locator contractor. 

Anthony Johnstone. 

It is wise to talk to a professional locator 

contractor and see what they use. Most 

of the time you will see professionals use 

some older units due to it being tried and 

tested. A lot of operators use locators 

that are over ten years old in design, but 

these operators swear by these units. 

I personally own an old RD400. I use 

this unit to do A B comparisons with 

newer units on the market. this was a 

popular unit in the 1990s. It normally only 

had two locate frequencies (8 & 33 kHz), 

you had to push a button to get depth, 

and you required training to get the most 

from the instrument. Why is it still so popular? 

Well, it did most of what a contractor 

needed without any unnecessary bells 

and whistles, performed well and was 

highly reliable, with many units still going 

strong and usually easily repairable. 

Remember when purchasing a new 

locator that you should look at exactly 

what you want to do.

the year of the hdd rig 

by Bob Martin, General Manager of HDD Broker Inc 

Despite a challenging year for the vast majority of the world, affecting both contractors and 

manufacturers, a few new developments survived – such as the horizontal directional drill (HDD) rig. 

“May yOu LIVe in interesting times.” It’s 

an old curse that has certainly held true 

for many people and companies over the 

last year. 

2010 has been a challenging time for 

the vast majority of the world. the global 

economic downturn has affected both 

contractors and manufacturers alike in a 

manner unseen for decades. Equipment 

development has certainly suffered as 

dealers reallocate research and development 

budgets to other areas in order to 

remain solvent. Fortunately, a few new 

developments have survived the recession 

to emerge this last year. 

Vermeer introduced its new D20x22FX 

series II directional drill back in January, 

which was designed specifically to tackle 

the newly emerging geothermal market. 

these machines are based off of their 

standard D20x22 drill platforms, but feature 

a boom capable of drilling from 

18 degree to 90 degree entry points. Built 

for vertical and steep angle geothermal 

loop installations, the D22x22FX also 

functions as a HDD that can install horizontal 

loops and conventional utilities. 

At the same time, Vermeer released 

information on their new line of fluid recycling 

systems to go hand in hand with their 

maxi rig lineup. Vermeer’s line of large 

directional drills spans pullback capacities 

ranging from 330,000 pounds to over 

one million pounds, launching them into 

an arena previously dominated by only a 

few other manufacturers. With the need 

to service the demands of these machines 

for fluid pumping and recycling, Vermeer 

launched their new line of recycling systems, 

which is currently seeing the first 

units delivered to anxious buyers. 

the rumour is also out that Ditch Witch 

is poised to test the first of their new line 

of maxi-sized directional drills in the coming 

months. these new machines are the 

result of an existing partnership between 

Ditch Witch and tu Xing sun No-Dig tech 

of Beijing, China. 

this development is truly pivotal, as 

its success could open the floodgates 

to Chinese equipment being accepted 

in North America as a viable option to 

compete against locally manufactured 

equipment. to date, Chinese equipment 

has met with enormous opposition by 

contractors due to its reputation of unreliability. 

Chinese equipment has already 

found huge purchase in developing countries 

such as India, and its introduction 

into North America, particularly as it is 

backed by a well known name, shall be a 

very interesting development to watch in 

the coming months. 

Ditch Witch also surprised the entire 

industry when it acquired the Earth tool 

Company and its Hammerhead product 

line in April. 

Earth tool was formerly strongly allied 

with Vermeer Manufacturing. this development 

basically hamstrung Vermeer’s 

pneumatic downhole tool program,

position to dominate that market through 

its well-established dealership network and 

Hammerhead’s proven line of tooling. 

universal hdd 

Another interesting development in the 

HDD rig arena is the emerging line of drilling 

machines manufactured by Universal 

HDD based out of Lake Zurich, Illinois. 

While it is too early to say exactly how well 

these units will hold up under demanding 

drilling conditions for the long term, 

short term results seem to show that the 

Universal lineup is holding its own – particularly 

when taking into account their lower 

pricing versus more well known brands of 

HDD rigs. 

Contrary to the trend of the larger manufacturers, 

Universal HDD has taken a 

different approach to building rigs, and 

that is to build them simple and build them 

cheap. While a new drill from the major 

manufacturers may feature such wonderful 

options as automatic rod loading, infinitely 

variable torque, or wireless accessibility 

for diagnostics, Universal has elected to 

build their machines with simple electric 

over hydraulic construction with a minimum 

suite of sensors and no low voltage electronics 

to malfunction at the jobsite. Again, 

the ultimate reliability of the machines is yet 

to be put to the test and only time will truly 

tell how well they hold up in the long run. 

hard rock drilling 

there is an interesting tendency within 

the industry in the tooling front as well. 

Hard rock drilling has always been a lucrative, 

if chancy subsection of horizontal 

drilling. In the past there were two main 

drilling methods used to tackle hard rock, 

those being mud motors and the wellestablished 

Ditch Witch At rock drilling 

system. 

Mud motors require large output pumps 

and recycling systems capable of processing 

the larger volume of spoils, while the At 

system uses proprietary pipe and specific 

At-capable drilling rigs. Both options are 

costly. 

A newly emerging trend for hard rock 

drilling involves the use of pneumatic air 

hammers. the technology has been out for 

a long time, however it is not until recently 

that pneumatic downhole hammers have 

seen more widespread use, due in part to 

many well-known manufacturers accepting 

the technology and offering it along with 

their machines. these systems require 

only the rental or purchase of a large 

capacity air compressor, something that 

is easily rented and readily available all

over the world. Pneumatic systems have 

equivalent or superior penetration in pure 

hard rock conditions, but do fall short 

when going through softer formations or in 

mixed soils. 

a look into the future 

the coming years will be interesting 

ones to watch. Of particular interest to most 

contractors will be the development of new 

technologies incorporated into HDDs, or 

perhaps the simplification of the same drill 

platforms to compete with potential international 

competitors in the marketplace. 

At any rate, it can be stated with certainty 

that drills will continue to evolve to satisfy 

the needs and wants of the marketplace. 

China is emerging as a potentially huge 

competitor in this arena like so many others 

it has already entered. the quality of their 

products is increasing in order to fill the 

needs of international buyers, and while 

the pricing is certainly cheaper for now, 

there will come a point where quality and 

cost will even out. 

Whether that point is one that still allows 

the current major players to compete in a 

competitive manner is yet to be seen, but 

you can be certain that just like their equipment, 

these manufacturers themselves are 

destined to evolve as well.

In search of a better way 

by Randy Happel, Two Rivers Marketing 

Product innovation and putting customer needs first has fuelled 

Vermeer Corporation on a quest to become a global leader in 

trenchless equipment and technology. 

IN The earLy 1940s, Gary Vermeer 

designed and built the first mechanical 

hoist for his grain wagon, an invention that 

transformed the backbreaking chore of 

unloading harvested crops into a simple 

task that could be completed with minimal 

effort in half the time. At that stage starting 

a manufacturing company was the furthest 

thing from his mind, but when other 

farmers saw the device in action Gary was 

inundated with requests to build one for 

them. so in 1948, Vermeer Manufacturing 

Company officially took root in a modest 

one-room cinderblock building that Gary 

and his cousin built on the west edge 

of the small rural farming community of 

Pella, Iowa. 

Over the past 60 years, product innovation 

– or “finding a better way” – has 

defined the Vermeer Corporation and is at 

the root of everything the company does. 

the wagon hoist was just one of the many 

“firsts” developed by visionary inventor 

and ideas man Gary Vermeer. Other notable 

inventions include a PtO-powered 

hammermill, stump cutter, tree spade and 

hydrostatic-driven trencher. today that list 

continues to grow with the development of 

niche products. While the same approach 

could describe almost any manufacturer 

that consistently develops a better product, 

at Vermeer it is just the beginning of 

the story. 

Gary stepped away from managing 

day-to-day operations in 1989, and under

have nearly doubled. the brother-and-sister 

team also remains steadfast in carrying 

on the traditions established by patriarch 

founder Gary. 

Not only is Vermeer recognised worldwide 

as being among the most innovative 

equipment manufacturers, but the processes 

by which it does so are equally 

impressive. Bob and Mary have discovered 

better ways not only for developing 

new products that ultimately better serve 

the needs of customers, but also internally, 

to streamline the manufacturing process. 

The "Vermeer mile", Iowa, US. 

continuous improvement 

CEO Bob Vermeer says “Vermeer has 

always been driven by change and a 

relentless search for a better way of doing 

things and that’s the type of culture we 

strive to instil into every Vermeer employee. 

It’s a process of continuous improvement 

and it takes place in every facet of our 

business – in every department, with every 

employee and in every corner of our world. 

to compete in the global marketplace, we 

must constantly improve and change. 

“Whenever Dad talked about products, 

he always used this phrase: ‘there’s 

got to be a better way’…a better way of 

installing underground services in rock, 

or drilling horizontally, for example, under 

rivers, roads and entire cities. Now we’ve 

taken it several steps further right here on 

the Vermeer mile.” 

What the Vermeer CEO is referring to 

by the “Vermeer mile” is the 1.2 million 

square foot Vermeer manufacturing facility, 

which lies directly across the road from the 

modest four-bedroom/one-bath farmhouse 

where Gary and wife, Matilda, raised the 

kids and remained until Gary’s death in 

2009. the facility is composed of six individual 

plants that collectively stretch an entire 

mile from west to east, encompassing some 

330 acres. And it doesn’t stop there. 

Across the Atlantic, Vermeer established 

European operations in Goes, the 

Netherlands, to serve the needs of Europe 

and the Asian markets in the early 1970s. 

On the other side of the world, the company 

also has a joint manufacturing venture in 

Vermeer Chief Executiver Officer 

Mary Andringa. 

Beijing, China – an expansion that has 

provided closer proximity to customers 

and market equipment in support of the 

huge infrastructure needs in China and 

other developing countries. Vermeer also 

has regional offices located in singapore 

and Brazil. 

Back in Pella at the Vermeer mile, the 

final instalment of the array of production 

facilities is the Vermeer Museum and Global 

Pavilion; a shrine to Gary’s entrepreneurial 

spirit that documents the history and importance 

of Vermeer’s many contributions to 

the equipment industry. Here visitors can 

view a number of artefacts – including 

many of Gary’s first inventions – and learn 

more about the growth of the company. 

the facility is also home to Vermeer 

University, the company’s in-house training 

department that offers numerous opportunities 

for employees to enhance skills at no 

cost to the individual. Manufacturing and 

technical skills, professional skills, sales 

and service, and leadership training programs 

are just a few of these educational 

opportunities. An auditorium within the facility 

is used for new product walk-arounds 

and equipment training, and also serves 

as a site for many local community events. 

The lean initiative 

since implementing the Lean growth 

strategy in 1997, Vermeer has been able 

to eliminate waste in most areas of the 

business. the focus is to provide maximum 

value to all stakeholders in the organisation, 

an initiative that has directly impacted 

key performance indicators including lead 

times, plant safety, quality and reliability, 

inventory control, profit and cash. the result 

has been a shift toward increased productivity 

and efficiency that puts recent years 

among the most dynamic periods in the 

company’s history. 

“It’s a culture that empowers people,” 

explains Vermeer CEO and President Mary 

Vermeer Andringa, “and encourages them 

to be a part of the process. the most important 

responsibility I have in my role within 

the company is to engage, empower and 

reward the contributions and efforts of everyone 

involved. to see people grow in their 

positions and become better in what they 

do every day gives me a lot of satisfaction. 

this means giving managers more leeway 

to try new things and take calculated risks.” 

“It’s a tremendous entrepreneurial environment,” 

says Marketing and Forage 

solutions Vice President Mark Core. “It has 

given me opportunities to develop skills at 

a much higher managerial level than I ever 

thought possible, and on a much grander 

and more global scale than I ever imagined 

when I first joined the company in 1991.” 

Employees have come to embrace and 

facilitate change. As a result, Vermeer 

can state proudly that employees truly 

are their most valuable asset. In the first 

decade since adopting the Lean growth 

strategy, Vermeer conducted 1,600 different 

Kaizen events. seventy per cent of 

Vermeer employees have participated in at 

least one Kaizen event and the executive 

team has logged an average of 20 events 

per member during the same timeframe. 

Glenda Vander Wilt, who heads up marketing 

for the industrial equipment division, 

says, “the ideas come from everywhere: 

Vermeer employees, dealers, customers 

and suppliers, from every corner of the 

world and for all market segments.” 

Ms Vander Wilt spent several years as 

the manager of Vermeer’s market-based 

strategy team, spending hundreds of hours 

each month visiting dealers and customers 

either in person or by phone. “It’s also a 

great way to build strong customer relationships 

on a global scale.” 

Going underground 

Among the many inventions of founder 

Gary Vermeer’s “firsts” was a hydrostatic 

trencher. this greatly minimised the manual 

labour necessary for installing the tile drainage 

systems that prepared farmland for 

production. It wasn’t long before Gary’s 

trencher concept evolved into a line of utility 

and track trenchers that soon became a 

mainstay of the company’s line of construction 

installation equipment. 

In 1991, Vermeer introduced the 

D-7t NAVIGAtOR, the first Vermeer horizontal 

directional drill (HDD), and the 

trenchless segment was off and running. 

the power and features packed into every 

Vermeer directional drill model help customers 

improve efficiencies and complete 

complicated jobs with less guesswork. 

In 2007, with the market for maxi drill rigs 

growing globally, Vermeer saw opportunity 

within the gas, oil and major water and 

sewer work areas. Vermeer acquired the 

HDD operating assets of Horizontal Rig & 

Equipment, a prominent manufacturer of 

maxi HDD rigs. 

today Vermeer offers a variety of horizontal 

directional drills. Whether the project 

involves energy pipelines, utilities, sewers, 

geothermal or high-speed communications 

lines, Vermeer HDD equipment has 

become a mainstay for contractors looking 

for equipment that can help improve 

productivity. Each one includes advanced 

technologies based on customer input, and 

customers know they can count on receiving 

expert service and support from the 

vast Vermeer worldwide network of factorytrained 

dealers and service technicians. 

“Our dealers are professional spokespersons 

for the Vermeer brands,” Vermeer 

says. “Many of them are sizeable enough 

to have rental fleets and work with customers 

on whatever their needs are. We 

encourage our dealers to be part of our 

planning process and to align their own 

planning with where we want to take the 

company overall.”

hdd gets bigger 

Completing the model range of the S Series, the new Terra-Jet 8522 S is the largest 

HDD machine ever built by Terra AG and was exhibited successfully at BAUMA, Munich. 

The machine is characterised by high power and drilling fluid volume. 

all you need in the driller's seat 

the Premium model of the terra-Jet 

8522 s is equipped with a comfortable 

driver’s cabin, which sets new standards. 

the cabin has all-round tinted glazing, 

with the machine side being glazed in a 

single uninterrupted panel. this allows the 

operator to see every detail of the drilling 

machine. 

Large windscreen wipers with jets clean 

the front and right panels. Additionally the 

drilling fluid pressure inside the drill rods 

is automatically released just before each 

drill rod change, preventing bentonite from 

being splashed onto the glazing. 

the on-board computer with a large 

10.4 inch touch screen displays the vital 

information needed at any instance. It 

updates and saves all relevant machine 

data every two seconds, updating the 

operator on the essential drilling elements. 

this data is essential for efficient service 

diagnostics. 

Additionally a bore log can be printed 

for each bore as regulated in the German 

specification DVGW 321. 

Sitting comfortably 

the operator sits in a comfortable operator’s 

seat, which can be adjusted to suit the 

body shape and weight of the operator. 

the operator’s cab is wide, allowing the 

seat to rotate 180 degrees. the operator 

can drill looking in the drilling direction, or 

can rotate the seat to be at right angles 

to the drill and observe every detail of the 

drilling machine. 

Machine technology 

the terra-Jet 8522 s may drill directional 

bores up to 400 m long and 1,000 mm in 

diameter depending on ground conditions. 

torque and pullback force are produced 

by separate hydraulic circuits allowing the 

maximum torque of 8,500 Nm and the 

maximum pullback force of 220 kN to be 

used simultaneously under full load. 

Separate bentonite chamber 

the drilling fluid volume is 400 litre per 

minute. the mixing system which mixes 

the bentonite into the drilling fluid via 

an injector (venture hopper) is on board 

the HDD machine. this patented system 

removes the need for an extra mixing system 

and a second engine. 

the bentonite high pressure pump and 

the mixing pump are placed in a separate 

chamber between the driver’s cabin and 

engine chamber. this aesthetically pleasing 

solution ensures that no bentonite 

touches hydraulic components. 

automatic drilling 

the machine is equipped with a second 

generation automatic drilling and backreaming 

system (ADBs). this patented 

system automatically adjusts the working 

speed of the drill to suite the ground 

conditions. 

In soft ground the drill operates at maximum 

speed, in hard ground slowly. this 

allows the operator to operate the drill at 

maximum efficiency in a controlled and 

relaxed manner and prevents the drill rods 

and drilling tools from being overloaded. 

During the pilot bore the ADBs controls the 

thrust force. If the drill head hits an unexpected 

obstacle, the ADBs stops the drilling 

speed immediately and drills very slowly 

through the obstacle – all automatically! 

Another new feature is the automatic drill 

rod greasing function, which is undertaken 

during each drill rod change by an electrically 

driven grease press attached to the 

driving saddle. 

New operator’s concept 

the drill operator drives and operates the 

HDD machine using the two multifunctional 

joysticks installed in the left and right armrests 

of the operator’s seat. Driving using 

the joysticks allows instantaneous control 

and smooth movement of the terra-Jet.

environmentally efficient 

technology in Berlin 

Since 1982, trenchless construction methods have represented an 

environmentally sound, low-cost alternative wherever underground 

pipelines are modernised or installed in Germany. 

The GerMaN SOcIeTy for trenchless 

technology (Gstt) was founded 20 years 

ago and campaigns to support this technology 

in other countries as well, through trade 

fairs, conferences and lectures. 

As a special highlight for the water industry, 

the International No-Dig Berlin 2011 is 

co-hosting an event with WAssER Berlin 

International. the Gstt would like to cordially 

invite you to attend the world’s leading 

trade fair for pipeline construction. 

Exhibitors are invited to present their 

products and participate in this headline 

event for the international water industry. 

A two-day conference program will provide 

specialists with unique opportunities to 

exchange experiences and information on 

trenchless technology. 

the Gstt welcomes the growing number 

of trenchless construction projects. In 

Germany, there is an increasing sense of 

awareness where environmentally friendly 

and economic construction methods are 

concerned. As the capital of trenchless 

technology, Berlin occupies a pioneering 

role, and together with other cities and 

municipalities is showing the way forward. 

throughout Germany, trenchless 

technology is used for 10 per cent of all 

new pipeline installations and 50 per cent of 

all pipeline rehabilitation, and the trend is on 

the rise. Among individual utility companies 

such as Berliner Wasserbetriebe (BWB) 

50 per cent of new pipeline installations on 

pipeline networks and pressure pipelines 

already employ trenchless technology. 

Berlin is an important location to demonstrate 

trenchless technology, and 

the 25 year success story of trenchless 

construction methods offers visible proof. 

By 2008, Berlin had more than 

750 km of collective and individual pipeline 

connections built with trenchless 

technology, saving a total of €64 million in 

construction costs and enabling this money 

to be invested in other construction projects. 

Excavation of 2.31 million m of soil was 

not required. the following measures were 

also averted: 

• Breaking open and restoring road surfaces 

totalling1.26 million sq m 

• Approximately 91,000 HGV trips transporting 

loads across the city 

• Extracting 204 million cubic m of groundwater 

(close to the equivalent of Berlin’s 

annual water supply). 

Make use of the opportunity to take part 

in the Building site Day (4 May 2011). At 

International No-Dig Berlin 2011 the focus 

is also on practical aspects. By taking part 

in organised tours at selected locations 

outside the exhibition grounds you can find 

out how the latest trenchless construction 

methods are proving their practical worth. 

trenchless construction methods represent 

groundbreaking technology and 

a modern concept that is economically 

efficient and environmentally sound. 

Exchange views with international specialists 

and establish valuable links with 

providers of products and services. Visitors 

to the International No-Dig Berlin 2011 

can also attend the trade fair WAssER 

Berlin International. 

Visitors to the event will discover all 

the latest developments in trenchless

technology, as well as find out about the 

state-of-the-art innovations in nearly all 

areas of the water industry. In conjunction 

with wat, the Specialist Water Conference, 

and a comprehensive conference program, 

the trade fair represents one of the 

world’s leading meeting places for the water 

industry. topics will range from climate 

change, pipelines, pumps and fittings to 

geothermal systems. 

By organising a host of innovations and 

improvements, the organisers have laid the 

foundation for exhibitors and trade visitors to 

establish easier contact and business links, 

thus providing visitors with a good number 

of reasons to attend No-Dig and WAssER 

Berlin International next May. 

Last but not least: welcome 

to berlin 

situated at the heart of Europe, Berlin has 

a population of 3.4 million. As Germany’s 

capital city, Berlin serves as a gateway 

between the European Union and Central or 

Eastern Europe markets. 

As the seat of Germany’s Federal 

Government, Berlin has 136 foreign embassies, 

more than 170 museums and art 

galleries with a truly impressive array of 

cultural events. 

the Gstt looks forward to welcoming 

exhibitors, delegates and visitors from 

around the world to this important international 

event.

No-dig 2012 

comes to Brazil 

by Sérgio A. Palazzo, Director of ABRATT 

In anticipation of the 2012 No-Dig Conference to be held in Brazil, ABRATT Director Sérgio A. Palazzo 

gives an insight in to why you should be there. He highlights Brazil’s rapidly developing economy and 

why opportunities for the development of Trenchless Technology in the country are overflowing. 

aLThOuGh The ‘brIc’ countries (Brazil, 

Russia, India and China) can be grouped 

together in terms of economic development, 

it is important to understand the 

different geo-economical situation of the 

four nations. 

It is important to highlight China’s 

incredible growth rate in the last two 

decades, but it is also important to highlight 

the tremendous challenges facing 

Brazil; to feed and to educate hundreds 

of millions of people. India deals with 

problems presented by its political situation 

– more open although not totally 

democratic – and finally Russia, one of the 

super powers of last century, faces a lot of 

controversy regarding its political situation 

which can generate a climate of mistrust, 

and can have a detrimental effect on the 

capital invested there. 

Despite these differences, a continentsized 

country with less than one fifth of 

the population of its ‘competitors’ seeking 

new investments, has some advantages 

over those strong secular countries. 

Production 

Brazil was listed at number four in 

car production this year with more than 

2 million units, behind China with 8 million, 

the United states with 7.6 million and 

Japan with 3.5 million. trucks are included 

in this figure, with 10 per cent or 200,000 

units in Brazil. this results in increased 

infrastructure construction. this positive 

economic development bodes well for 

forward thinking companies smart enough 

to invest this burgeoning region. 

Positive indicators include: 

• $1.8 trillion reais ($Us1.1 trillion) of 

GNP, means that every investment plan 

means billions of dollars. 

• Infrastructure (transport only) will take 

1 per cent of GNP per year till 2023. 

• sewer investments, for a country that 

collects only 40 per cent and treats 

less than 20 per cent, means a lot of 

potential opportunities. 

• sewer rehabilitation in state capitals 

require a huge investment of $20 billion 

Reais ($Us11.9 billion) till 2023. 

• Fibre optic and broadband in Brazil 

means thousands of kilometres of buried 

cables 

• Hundreds of thousands of kilometres 

of cast iron and asbestos cement pipelines 

still supply potable water in the old 

downtown of huge cities across Brazil. 

• scheduled international events 

increase all prospects (soccer 

2014 and Olympic Games 2016) and 

everybody knows what that means. 

• Billions of dollars worth of investments 

in energy projects, including plans by 

one of the world’s largest oil companies 

to build more than 7,000 km of oil and 

gas pipelines. 

there’s no excuse for not coming to 

Brazil, a democratic country with a solid 

economic position, strong reserves (more 

than $R200 billion), low inflation and a 

very attractive interest rate for your investment 

beyond the huge and previewed 

investment in infrastructure. 

ABRAtt promoted the fourth edition 

of Brazilian trenchless technology 

Congress and the second No-Dig Latin 

America from July 21 to 22, 2010 in 

são Paulo city. Participants and exhibitors 

at these conferences had the same good 

feeling about Brazil’s opportunities for the 

next 20 years. 

the Congress had 400 participants and 

the No-Dig show had almost 600 visitors. 

With more than 1,000 participants overall, 

the attendance at these events was considered 

extremely good. 

the 2012 No-Dig International 

Conference is sure to be another successful 

event and we look forward to receiving 

you there.

About Istt/Membership 

the Istt is the umbrella organisation for trenchless technologists in over 40 

countries of the world. In 22 countries groups of trenchless technologists have 

their own national groups which are affiliated while the remainder are registered 

directly with the Istt. 

trenchless technology covers the repair, maintenance, upgrade and new 

installation of underground utility services using equipment and techniques 

which avoid or considerably reduce the need for excavation. the Istt promotes 

research, training and the more extensive use of trenchless technology 

through publications, co-operation with other NGOs, an annual international 

conference and an interactive website. 

trenchless technology is recognised as an environmentally sustainable 

technology and is particularly suited for use in densely populated urban 

areas by reducing disruption to peoples daily lives, social costs (traffic congestion, 

damage to road surfaces and buildings, air quality), noise and dust. 

trenchless technologies also have a considerably reduced carbon footprint 

compared to trenching in most situations.
