Project Detail

Project: San Diego Marriott Seawall Repair
Owner: CCMH San Diego LLC
Start date: 4/19/2004
Finish date: 6/10/2005
Value: $3,126,071

Work involved the repair of 1200 lineal feet of a steel sheetpile seawall. 30 foot aluminum cofferdams were utilized to provide a dry work area due to water quality issues, since a third of the wall repair was in the tidal zone. A 6 inch reinforced concrete wall encapsulation was placed in front of the existing sheetpiling. Continuous dewatering of the cofferdams was required to keep them dry. Mitigation was performed in the bay for the new concrete wall. Challenges included a very tight work area, pedestrian control and safety along the existing promenade, and working around the busiest marina in San Diego.
