Seattle Federal Office Building

The Seattle Federal Office Building was built in 1932. Its granite, brick, and terra cotta masonry cladding, steel windows, and aluminum panels are in need of repair. Working with the design-build partner, Lydig Construction, SHKS is leading the design effort and has performed and coordinated masonry cleaning, mortar analysis, and brick material analysis in an effort to evaluate and recommend appropriate materials and techniques for rehabilitation. As part of a window repair scope, SHKS evaluated several alternatives to repair deteriorated windows and improve thermal and acoustic performance characteristics. The client, GSA, is currently considering replacing existing single pane glazing with 1/4” vacuum insulated glazing (VIG). Construction is just getting underway this summer with anticipated completion by Fall 2021.
