About

GTA provided geotechnical engineering, environmental consulting, and construction observation and testing services during construction of the foundation of the 23-story, 550,000-SF, 380-unit apartment building with ground level retail space, and seven-story parking garage. Geotechnical services included design of the drilled pier deep foundation system for the structure. GTA oversaw the installation and performance of over 100 drilled piers ranging from 2.5 to 5-foot diameter, and 50 to 120 feet. Several bi-directional load tests and a Statnamic Load testing program were employed to confirm the design assumptions and the contractors’ means and methods.
