Stewart Milne Timber Systems has been appointed to design, supply and install the structural timber frame. It was selected on the back of a previous subcontract building Stobhill Hospital in Glasgow in 2008.
The new Ayrshire community hospital will be built in Irvine, covering an area of 12,465 square metres, with the external walls being closed pre-insulated panels. Parts of the hospital will be made offsite.
Stewart Milne Timber Systems group managing director Alex Goodfellow said: “This a major and important new facility for Ayrshire and the surrounding area, and using timber systems in the build programme will mean the hospital will enter working use much sooner.
“Offsite manufacture as a central part of the project will allow for a faster build process, much better energy performance and less waste produced both in the factory and onsite. Meeting deadlines is a critical element of this project, so we’ll be working very closely with Balfour Beatty throughout to ensure the hospital is delivered on time and on budget.”
Balfour Beatty was selected in February as the preferred bidder for the project, which is being funded using the Scottish government’s non-profit distributing (NPD) model, and reached financial close last month.
Stewart Milne Timber Systems will work to a 23-week build schedule, beginning in November 2014 and is expected to be complete by May 2015. To further speed the build, expert teams will manage a scaffold-free build onsite. The roof trusses of the hospital will also be constructed on the ground and hoisted into place by crane to reduce working at height.
The wall panels provided by Stewart Milne Timber Systems will offer a U-value of 0.22, roofs 0.16 and air tightness of 5.
Alex Goodfellow said: “Using a scaffold-free erection and multiple erect squads will make the 23-week programme faster, safer and reduce costs. This is a highly innovative approach to hospital building and demonstrates the commitment of all parties involved to build a valuable new public health facility quickly, while also providing significant value for money and energy efficiency over the life of the building.”
The hospital will feature 140mm external wall closed panels with 120mm 0.022 polyurethane insulation, and roof trusses with 18mm plywood sarking. All internal partitions will be erected with 9mm OSB sheathing, with bathroom pods loaded in by Stewart Milne Timber Systems.
