Pier 70 Shipyard Grade and Abatement 

JHCE provided office engineering, construction inspection, and managed the construction management team for the Pier 70 Shipyard Grade and Abatement project which included removal of a pipe contaminated by polychlorinated biphenyls (“PCBs”), placement of SediMite carbon to remediate PCBs, re-grading existing stockpiles, and placement of durable cover to create a level surface with positive drainage.

JHCE provided a construction inspector who oversaw the removal of the existing contaminated pipe, the re-grading of massive existing stockpiles, significant fill placement for the increase of site grades, and grading and abatement of hazardous materials. JHCE also inspected the installation of a demarcation layer and a compacted durable cap for safe confinement of on-site contaminated soils. 

JHCE confirmed positive surface drainage was maintained intermittently during construction and worked closely with Yerba Buena Engineering (contractor) and CDIM Engineering (engineer of record) to ensure the project specifications, risk management plan (“RMP”), and the environmental health and safety plan (“EHASP”) were being properly adhered to.
