• Project: 635/645 Elliott Avenue
  • Location: Seattle, Washington
  • Client: Martin Selig Real Estate
  • Architect: Hinthorne Mott
  • LEED: LEED Gold

Lewis built two four-story, post-tensioned concrete office buildings of 360,000 square feet, plus 560 below-grade parking spaces.  We addressed heavy groundwater at the century-old waterfront fill site with an innovative Cutter Soil Mix (CSM) shoring wall.  The project has been awarded LEED Gold.  The buildings accommodate both office and life science tenants with large floor-to-floor heights on the first two floors, and infrastructure that can be expanded for intensive uses.
