Cost-Effective Sediment Remediation at Port of Richmond on San Francisco Bay

This paper presents a case study of a cost effective sediment remediation project that occurred in 2005/2006 at Operable Unit No. 2 (OU2) within the Point Potrero Marine Terminal (PPMT) at the Port of Richmond. The Port employed an innovative capping strategy for containing contaminated sediments in a marsh area. The paper discusses aspects of the cap design, complexities involved with environmental permitting, and contractor means and methods employed during construction. This paper concludes with a summary of consulting and construction contracting methods and cost. The project was completed by the Port with consulting assistance from Weiss Associates, ANWest Engineering, and Fugro West. Dutra Marine Construction performed construction activities.
