SDA provided civil engineering design in support of this new building for the Microsoft Corporation on the former Safeco Campus located in Redmond, Washington. The five-story building added over 270,000 square feet of new office space with an associated four-story underground parking garage. SDA was responsible for the access road design, ADA and pedestrian access, onsite utilities, grading and retaining wall design, site layout and storm drainage for this project. Our involvement began with entitlement of the project and continued through construction administration.
