This task order was completed by Remedial Construction Services, L.P. (RECON) under a five-year Indefinite Delivery Indefinite Quality (IDIQ) cost reimbursable (time and materials) contract with Chevron for environmental remediation in the United States.

The abandoned pier site consists of 65 acres of land located in the extreme southwest corner of the City of Bayonne at Bergen Point. It is bound on the east by the Bayonne Bridge, to the south by Kill Van Kull (channel) and to the west by the South Reach of the Newark Bay. The pier was built around 1910 and remained operational until the early 1990s. The pier extended westward into the South Reach of Newark Bay and during operation was used in the off-loading and loading of petroleum products to, and from, ocean going ships and barges.

Abatement

The pier was a two story, concrete structure, approximately 640 feet long by 75 feet wide and was supported by timber piles. The scope of work for the demolition phase was to clear the structure of asbestos tiles and sheeting, lead-based paint, product piping, transformers, light ballasts, and pigeon droppings. Work was complicated by the fact that the pier was partially collapsed -- limiting access for the abatement crews and requiring shoring of the structure to prevent further collapse during abatement.

Demolition

The concrete structure was demolished using excavators equipped with grapple attachments and the rubble was transferred to an inshore portion of the site using off-road dump trucks. The original work plan called for demolition of the structure using a barge-mounted crane equipped with a hydraulic shear. RECON modified and increased productivity by starting from the inshore area and working toward the out-shore end of the pier using the rubble and existing piers as a platform for the demolition equipment and haul trucks.

Using trackhoe-mounted demolition equipment, the concrete rubble was segregated and sized. RECON also excavated 20,000 cubic yards of additional rubble and soil from under the former pier area using a combination of land-based hydraulic excavators and a barge-mounted clamshell equipped crane. This material was transferred to the inshore area for management by the redevelopment contractor.

Additional Activities

RECON restored approximately 800 feet of combined sheetpile reinforced shoreline and a timber relieving platform that was then sloped and covered with geotextile and a 3-foot thick layer of armor stone.

Prior to the start of demolition and shoreline restoration operations, RECON installed 2,000 feet of turbidity curtain and containment booms within Newark Bay to limit migration of sediment and floating contamination from the work area.

Other activities completed by RECON involved draining and decommissioning of 12 transformers and installing 1,000 linear feet of 30-inch reinforced concrete pipe drainage culvert with manholes.
