In North East Portland sits the new Harder Mechanical Headquarters constructed with Mass Timber. This 27,000-square-foot, three-level project features a structural steel frame with 25,,000-square-feet of Cross Laminated Timber (CLT) floors and roof diaphragm with a BRBF lateral system. The city is to complete its new earthquake-resistant police and emergency management building. Swinerton is providing timber engineering services on the project for the Mass Timber/CLT scope. The project is exciting to be a part of as it shows that mass timber is becoming more commonplace in commercial office space.
