SDA provided civil engineering design support of two new buildings for Microsoft Corporation on the former Safeco Campus located in Redmond, Washington. The two buildings will add over 540,000 square feet of new office space with associated underground parking to the existing campus. The completed project will seek LEED silver certification for the buildings. SDA was responsible for access road design, ADA and pedestrian access, on-site utilities, grading and retaining wall design, site layout and storm drainage design for the project. SDA's involvement began with entitlement of the project and continued through construction administration.
