Lewis built a new 280,000 square foot office building with four levels of below-grade parking with 400 spaces. The difficult historic shoreline site included old foundations, debris from the Great Seattle Fire, and a high water table, which the team addressed with an innovative Cutter Soil Mix (CSM) shoring wall. Lewis completed the project two months ahead of schedule, while working between two historic buildings in Pioneer Square. In other Starbucks work, Lewis has built out approximately 700,000 square feet of the company’s headquarters at historic Starbucks Center.
