The U.S. Navy upgraded berthing facilities at NAVSTA San Diego by constructing a replacement pier for existing Piers 10 and 11. 

Project Highlights :

• Group Delta Consultants (GDC) performed a geotechnical investigation for the construction of the replacement pier, dredging of berthing areas, and onshore improvements
• GDC staff directed a geophysical survey to identify any fault traces in the vicinity of the replacement pier 
• Geotechnical recommendations were provided for two-level seismic design of the pier and for large displacement concrete piles driven into dense, sandy Bay Point Formation
