The interlocking system of this project called on all the capabilities of TimberLab’s 5 axis CNC bridge to achieve the 1mm tolerances demanded. The result is an outstanding example of the craftsmanship possible in large scale timber structures.
Andrew Barrie commented,” Cathedral Grammar Junior School’s Laminated Veneer Lumber structure combines traditional timber jointing techniques and up-to-the-minute fabrication technology. The design pushed the limits of new CNC timber milling technology to allow the economical use of exacting traditional timber joints normally thought too expensive or technically demanding. The architects, engineers, contractors, and Timberlab worked together to meticulously design and review every element of the structure. Timberlab’s computer-controlled milling machines then pre-cut the LVL elements to superfine +-0.5mm tolerances to ensure structural performance and perfect fit. The timber elements arrived on site complete down to the smallest hole and rebate. The assembly was rapid and precise – even faster than expected – and with no on-site modifications required. The Cathedral Grammar Junior School is what craftsmanship looks like in the 21st century – digital design and fabrication tools combined with traditional ideas and techniques to make beautiful, exciting new spaces.
