Amazon Corner Construction Update

Construction is moving along at Amazon Corner in South Eugene. Having completed the post-tensioned slabs of the basement and first floor, Essex Construction is installing the wood wall framing for the housing units. Before the weather turned, walls were being pre-fabricated on-site through a makeshift assembly line. Once completed, a stack of walls was lifted by a crane onto the building floor plate and then each wall was tilted into place. Currently, workers are constructing more traditional stud walls. In the installation of the floors, workers are hanging floor joists from the wall framing—a technique that has become standard in Portland. Many structural engineers prefer this method for a host of reasons: it eliminates rim boards, uses less wood product overall, may reduce building height shrinkage, and offers better insulative performance.
