Project Engineer for the evaluation <br />of a damaged existing 8-inch and 18-inch sewer that resulted in the formation of a sinkhole within Pier F <br />Avenue, located within the Port of Long Beach. The project included CCTV of the damaged pipe, bypass <br />pumping of sewer flows and cleaning of the pipes in order to assess the damage. After the evaluation, <br />repair options were evaluated including open cut and trenchless technologies. Repair options had to <br />include mitigation of the high groundwater within the Port due to tidal influence. Cut and cover, <br />microtunneling and rehabilitation of the damaged pipe utilizing pipe bursting, spiral wound sliplining, and <br />sliplining methodologies were evaluated. Traditional cut and cover was the recommended repair option. <br />TETRA TECH <br />
