Fox Tower is located on the block bordered by SW Broadway and Park avenues and SW Yamhill and Taylor streets. The structure has 28 levels above grade and four below-grade parking levels. The building footprint occupies the entire block and extends to the property lines. The excavation required to construct the basement levels reached a maximum depth of 65 ft. A shoring/bracing system was necessary to support the excavation. GRI performed a detailed geotechnical investigation to evaluate subsurface materials and conditions at the site and developed recommendations for floor and foundation support; shoring and shoring performance provisions; embedded wall design; and subdrainage. The geotechnical investigation for this project included a site-specific seismic hazard study. GRI personnel provided on-site observation services and consultation during construction of the shoring and foundation system.
