Churches Housing Association Timber Frame Build & Train Scheme By Tim Denne & Steve Carey
Scheme
Summary
Scheme
details
Oregon Timber Frame is totally sustainable timber, with the added
incentive of it being UK home grown timber taken from Scottish Border
region Keilder forests.
The external wall construction consisted of an external skin of 100mm
face brick, a 50mm cavity and an internal timber frame skin of 100mm.
This gave a `U' value of 0.38, thus being well below the 1995 Building
Regulation Part `L' requirement of 0.45, resulting in a highly thermally
efficient unit.
The general standard of the building was further improved by using high
exposure rated double glazed windows from Allan Brothers of Scotland and
incorporating the very best sound insulation methods between separating
floors and walls.
Training
Scheme
The training involved the trainees visiting the head office and factory
of Oregon in Jedburgh, Scotland, to undergo manufacturing process
training and practical on-site timber frame erection experience. The aim
was to equip the trainees with a multi-skilled ability for the trade
covering all aspects of the erection, first and second fix elements of
the timber method.
The ultimate aim was to integrate the trainees into the full-time
employment market as we had identified a specific skill shortage in the
timber frame field in the Dorset region. Their chances of full-time
employment have been greatly enhanced by them having the multi-skilled
ability at a time when the industry is moving towards a truly sustainable
development method of thermally efficient building, in line with the
demands of the housing industry, in particular, that of environmentally
aware Housing Associations.
Cost
Implications
We have found that the construction cost using the timber frame method to
its full advantage, resulted in total contract cost on this first project
comparable to masonry construction costs, but allowing for the increased
revenue from the early rental income, due in the short contract period
identified a definite saving over a masonry contract. For future
projects we are confident that by using Oregon Partnership's expertise in
the total contract construction management package, we should be able to
identify an actual construction cost saving against masonry construction
of around 5% - 8%.
The six flats have now been occupied by the trainees for a year.
Discussions with the trainees have confirmed our original thoughts, the
flats which are of around 35m2 have been extremely efficient with regard
to heating and we estimate have saved around 35% of the normal heating
bills.
Bournemouth
Churches Housing Association's Opinion
Bournemouth Churches have adopted a policy for the use of timber frame
construction on all of their future developments specifically designed to
incorporate the use of the UK home grown sustainable timber. They are
committed to continue to promote Build & Train projects throughout Dorset
and have recently launched, in conjunction with Oregon Partnerships, a
Rural Housing Initiative aimed at providing life time sustainable homes
at affordable rents within small rural communities. This will help halt
the migration of local young people from our villages which is identified
as one of the problems of increased homelessness in our cities.
