Partnering Allows Container Wharf Construction in Record Time at Port of Los Angeles Berth 100
To receive four tenant-purchased container cranes being delivered from China, the Port of Los Angeles needed to complete the first 305 meters (1000 feet) of a 366-meter (1200-foot) concrete container wharf in record time at its new Berth 100 Container Terminal facility. The originally planned 12-month construction period, a typical duration for a project of this nature, had been shortened by 5 months due to delayed issuance of a required permit. The remaining 7-month construction period was further interrupted for a total of about 1 month due to a court restraining order and a labor action. The Port of Los Angeles was able to complete 305 meters (1000 feet) feet of wharf with only 6 months of active construction as a result of consistent and effective partnering with its contractors. Working together as a team, the Port's designers, construction managers, and the general contractor and subcontractors were able to identify, evaluate, select, and implement actions to meet the demanding schedule. Solutions involved design modifications, sequencing modifications, and work shift modifications. Design modifications included an expanded and early indicator pile program, pre-contract surcharging, adjustment of deck expansion joint locations, shortened time between primary and secondary concrete pours, and elimination of some soil-strengthening displacement piles. Construction sequencing modifications included re-sequencing the construction of the wharf from south to north rather than the specified direction, separating the dredging into two mobilizations thus removing toe dredging from the critical path, and removing waterside displacement piles from the critical path.
