Seismic Upgrade of a Historical Wharf at the Port of Los Angeles

A major project is underway at the POLA that proposes to create approximately 35 acres of land and water for a world-class marine research institute. Approximately 2,540 ft of existing wharves at Berths 57-60 will be upgraded in Phase 1. This is the oldest wharf built in San Pedro Bay and the existing wharf and the shed have been designated as “historic.” This designation requires preservation of the exterior appearance of the shed as well as a visible portion of the wharf located above water. Additionally, POLA is located in a highly seismic area and the proposed project allows public access, thereby requiring any upgrades to meet current building codes. Initial evaluations indicate significant improvements are needed to meet current seismic requirements in addition to repairs for the proposed project. This paper discusses the seismic, structural, and geotechnical aspects of the project and compares various upgrade alternatives considered for implementation.
