Structural engineering and design of the West Landing, which is a concrete approach structure that connects the new Pedestrian Bridge over highway 520 to the Microsoft West Campus Commons. The grand stair and part of the bike path ramp sit atop the existing 4-level underground parking garage, which requires strengthening of the garage deck to support the new loads. Since the existing garage walls have permanent soil nail support, pile foundations were used to avoid imposing additional surcharge loads onto the basement walls. This complex project needed to satisfy many geometric requirements as well as the functional and regulatory requirements from many different stakeholders.
