Document Description
The proposed project involves repair of an existing concrete deck and piles at the National city Marine Terminal (NCMT) Berth 24-10 (Berth) located in the City of National City. The Berth is comprised oa reinforced concrete marginal wharf structure consisting of pre-stressed concrete piles and a supporting cast-in-place concrete deck, which was constructed between 1968 and 1971. Since it was first constructed, the Berth has suffered substantial structural damage and deterioration. Specific problems include damage to the concrete deck soffit and damage with cracking to approximately 17 percent of the pre-stressed concrete piles. The damage has resulted in interim load restrictions and the closure of portions of the concrete deck. Furthermore, the Berth does not meet current seismic design standards and if subjected to ground motion, would suffer significantly more damage than a modern wharf structure subjected to the same motion. The proposed project would address these structural vulnerabilities by repairing the damaged piles and constructing a new concrete deck that would be constructed in-kind, in the same location as the same existing concrete deck. In addition, the proposed project would improve the mooring and fender system, utilities and storm drainage system, and electrical system.
