Replacement Fuel Storage Tank San Diego Naval Air Station San Diego, California Back to Project List   Vibratory Ground Improvement Dry bottom feed stone columns are installed to support four large aviation fuel storage tanks at the San Diego Naval Air Station. Project Overview: The former Naval Air Station aviation fuel storage tank site is located in the northern part of Coronado Island. The site is considered to be potentially unstable during a major seismic event. The phenomenon of liquefaction could occur at this site and ground improvement was warranted in order to mitigate the damage to the fuel storage tanks and to avoid potential spillage of aviation fuel into the San Diego Bay. Layne GeoConstruction installed a total of over 1,500 dry bottom feed stone columns and vibro compaction points, to a depth of 40 feet for soil improvement at the Naval Air Station to support the four large aviation fuel storage tanks. Densification was implemented to solidify the saturated loose sandy soil deposits found directly below the locations of the storage tanks at the project site.   Value of Work Performed: $835,000 Project Duration: 5 months Project Completion Date: November 2002 Project Reference: Owner: United States Department of the Navy Aaron Smith General Contractor: NOVA Group, Inc.
