Abstract
The City Creek Center urban redevelopment project in Salt Lake City, Utah involved excavations up to 65 feet deep. Shoring systems included more than 29,000 square feet of anchored diaphragm walls, 100,000 square feet of soil nail walls, and 860 linear feet of underpinning. Detailed performance monitoring alerted the project team to unacceptable performance of an anchored diaphragm wall adjacent to an occupied twenty-five-story building on shallow foundations. This knowledge allowed the team to react quickly, stabilize the excavation, investigate the situation, and develop successful remedial measures. The diaphragm wall was reinforced with additional anchors and subgrade concrete struts, allowing the excavation to proceed with minimal delay and no damage to the adjacent building.
