Latest photos from the timber testing of the sweet chestnut joists from Inwood that will form the roof of the Balliol College Sports Pavilion with Niall Mclaughlin Architects is now complete. The roof will consist of 10 stacked layers of #timber joists.

Apart from material properties testing, two stacks were load-tested at Cambridge University Engineering Department, reinforced with screws and un-reinforced up to working load and to failure to investigate the behavior at contact points between the heavily loaded lower layers.
