Heavy timber office buildings haven’t been built in Seattle since the 1920s because they required old-growth trees with large circumferences to support the weight of upper floors. But the columns in the Bullitt Center are made by gluing together smaller beams to form columns that are just as strong.
Those glue-laminated beams, or glulams, are made at Calvert Company in Vancouver, Wash. This video follows the process of making the glulams from sustainably harvested Northwest timber.
