Provided design services for the renovation, addition, and seismic upgrade of this three-story (plus basement), 38,000-sf unreinforced masonry historic building in downtown Portland. The project included adding a new basement level to allow for two levels of parking and a new fourth level. The seismic retrofit scheme provided a design that accommodated open spaces and preserved the historic character of the building. The project experienced less than 1.5% in structural construction change orders despite the fact that little or no documentation was available for the original building. While with another firm, Chris Thompson served as Principal-in-Charge and John McDonald served as Project Manager.
