Canadian OSB, SPF and Hemlock Used to Construct Shoe Factory
Recently Kevin Bews (COFI, SPF Group) and I had the opportunity to visit a 1-storey non-residential platform-frame construction site in Yokote City, Akita Prefecture. Once completed, a Tokyo-based shoe design and manufacturing company will produce their hand made high-end women’s shoes in this new factory. The architect originally planned for a steel frame building but as this was over budget they decided to look at wood. Due to the heavy snow loads in this area – up to 2 meters – the building had to have a very strong roof structure so they eventually chose a wooden truss system constructed with Canadian SPF lumber. To provide for higher insulation values the walls used 2×6 dimension lumber, sheathed with 9 mm, 3 x 10 Canadian OSB. The excellent cost performance of long-length Canadian OSB allowed for cost savings that the companies involved believe will help achieve a project that is within budget.
While visiting the project we were happy to discover that Canada Tsuga treated sill plates were used throughout the building so the various wood products that the Canada Wood Japan Office promote were well represented in this one project!
The platform-frame wall panels were provided by Akita based Taguchi Mokuzai and the wood trusses from Prime Truss’s Tohoku plant near Sendai. The floor area of the building is 462 m² and construction will use 8.46 m³ of OSB, 41.43 m³ of SPF (17.43 m³ in the walls and 24 m³ in the trusses) and 4.71 m³ of Canada Tsuga. The project is scheduled to be completed by the end of October this year.
