The Gates Foundation project consists of a new $500 million facility constructed in two phases on a 12-acre campus. With the completion of Phase 1, the campus includes two six-story buildings, totaling 900,000 square feet with 400 stalls of underground parking, and an 11,000-square-foot visitor’s center. This project also includes a two-acre, 1,020-stall, five-story underground parking garage, totaling 356,390-square-feet, built across Fifth Avenue in collaboration with the City of Seattle. The buildings and parking garage are LEED Gold certified with more than half an acre of green roofs and a rainwater collection and storage system.  Phase II will add an additional 400,000 square feet to the campus and include a third building located to the east of the two existing buildings.  Inspections included reinforced concrete, shotcrete, shoring, structural steel fabrication, ultrasonic testing, welding, masonry and fireproofing.
