Atlantic Wood Industries Superfund Site, Portsmouth, Virginia
July. 2011

On July 7, 2011 McLean Contracting Company Was awarded a contract with the U.S. Army Corps of Engineers for the construction of an Offshore Sheet Pile Containment Wall at the Atlantic Wood Industries Superfund Site located in Portsmouth, Virginia.  The Contract was awarded on a Lowest Price, Technically Acceptable Offeror basis.  The Contract is valued at $18,424,000.  Work is expected to commence in the fall of 2011 and the Base Contract will be complete in spring 2013.  Moffatt & Nichol is the designer of record for the project.

The Sheet Pile Containment Wall project is adjacent to McLean’s on going work for the new Jordan Bridge connecting Portsmouth and Chesapeake, Virginia and spanning the Southern Branch of the Elizabeth River.

The Offshore Sheet Pile Containment Wall structure consists of

approximately 1,180 feet of steel combination pile bulkhead constructed in the Southern Branch of the Elizabeth River;
120 feet of tied back steel combination pile bulkhead constructed along the river shoreline;
370 feet of steel sheet pile cutoff wall constructed onshore

The offshore combination pile wall is comprised of plumb 48 inch diameter steel pipe piles with z-shaped steel intermediate sheet piles, supported by battered 36 inch diameter steel pipe piles, and topped with a reinforced concrete cap. Work incidental to the project includes sunken barge removal, timber pile removal, debris removal, and miscellaneous grading.

The wall is a major component of the cleanup at the site, and is designed to contain existing contamination land side of the wall and contaminated sediment that will be dredged in the future and consolidated behind the wall.

The construction of the Containment Wall is one of the initial stages of the remediation at the Atlantic Wood Industries Superfund Site and part of the on-going clean up operations within the Southern Branch of the Elizabeth River.
