MVHR-Easy with Posi-Joist
Cambium Gardens, located within walking distance of the All England Tennis Club in Wimbledon, is a new ‘urban village’ location
surrounded by protected parkland. It offers 55 apartments and 55 houses in the leafy setting of Southfields, all carefully designed
around a 200 year old oak tree, believed to have been planted by renowned landscape architect Capability Brown.
The project is designed to Code for
Sustainable Homes Level 4, the
development meets the Lifetime Homes
standards with 10% wheelchair accessible and
the Mayor’s London Housing Design Guide.
About the project
When McLaren
Construction (one of the
UK’s most successful
privately owned
businesses) involved
Howarth Timber
Engineered Solutions in
this ambitious project, they
shared with them a brief to
construct very energy
efficient buildings with
large open rooms but keep the building mass to a
minimum for their luxury development apartments
and houses.
McLaren Construction teamed up with Howarth
Timber Engineering Solutions, via the carpentry
installers J A Stott, in order to use their expertise
and the MiTek PAMIR software to meet the
required specification.
Whilst working on the Cambium Gardens project, it
was identified at an early stage that the pre-cast
concrete slabs originally specified would not work
and an alternative in the form of MiTek’s Posi-
Joists was tabled. This lightweight solution allowed
for the complex Mechanical Ventilation Heat
Recovery (MVHR) ductwork & building services to
be hidden within the floor joist zone, maximising
the living space within the buildings.
Howarth Timber Engineered Solutions, using the
latest EC5 compliant MiTek software PAMIR to
design not only the Posi-Joist floor joists but also
using the 3D capabilities of PAMIR, ensured that
the MVHR ductwork was able to traverse
the floors of the luxury
apartments and houses.
HTES
worked
directly
as an
integral part of the project design team producing
interactive 3-D models and BIM compatible
design solutions so that the entire design team
could check and sign off the proposals before any
work was carried out on site. The MiTek PAMIR
software is able to produce
not only .dwg drawings, but
also .pdf files, CAD
drawings as well as
Industry Foundation Class
(IFC) files – to be imported
into Revit. This coordinated
approach saved both time
and money on the build for
the Contractor, Architect,
Engineers and M&E
designers.
About MiTek
Based in Dudley in the West Midlands, MiTek
specialise in the development of software
solutions for structural timber engineering and the
provision of steel connector products for floor and
roofing systems.
Since its foundation in the mid-1960's, MiTek have
gone from strength to strength, growing both
organically and through acquisition to become
market leaders, operating worldwide by delivering
leading software solutions that are second to none.
PAMIR
The modern roof designer needs to be able to
design a roof very quickly. With several new
enquiries arriving on their desk every day, they
need software solutions that enable them to
design and quote roofs in no time at all. This is one
of the many reasons that it was used within the
Cambium Gardens project.
PAMIR's speed of framing is undoubtedly
amazing.
In just four clicks of the mouse the user can input
this sizeable building, fully framed and ready to
price. With PAMIR you can quickly edit the
building dimensions and watch the roof
dynamically re-frame. Whether you are moving
walls, adding an attic room, changing the roof
pitch, or mirroring roof features, Pamir's powerful
dynamic framing allows you to make the change
in seconds.
PAMIR combines roof layout, truss engineering
and high quality CAD output features, all into one
integrated software platform. This means that roof
designers have just one environment to learn and
are more productive, faster.
Developed by MiTek’s large European team of
software professionals, PAMIR has been
enthusiastically welcomed by the industry and
looks set to change roof and floor design as we
know it.
In conclusion
Lend Lease, head of residential Richard Cook, said
“Cambium will create a vibrant new community in
the heart of Southfields and we are delighted to
welcome councillor Cook and pupils from Our
Lady Queen of Heaven today to mark this
significant development milestone: the start of
work on site.
”A highly sustainable scheme, Cambium delivers
the best of contemporary and eco-friendly living
for new and existing residents in the borough of
Wandsworth.”
