The development of a seven-story office building with a four-story underground parking garage, located adjacent to the Alaskan Way viaduct just south of downtown Seattle posed unique challenges. The project was situated on a sensitive site with specific soil conditions and a high water table. The team identified early on the need to develop strategies to minimize the risks associated with the site conditions both during construction and over the long term. The site conditions along with the project requirements were all considered in the selection of the appropriate shoring system and waterproofing system for the structure.
