PORT OF DAVISVILLE – PIER NO. 2 RECONSTRUCTION

Located near the mouth of the Narragansett Bay in North Kingstown RI, the Port of Davisville is listed among the top auto and frozen seafood ports along the East Coast of the United States. The pier offers four berths and five terminals with 58 acres of laydown and terminal storage. As part of the Reconstruction Project, Manafort Transit was contracted to construct 1200 LF of new marine bulkhead at the south side of Pier 2 to encapsulate the existing 1940s US Navy built cofferdam cells.

Work included predrilling to a depth of 60 ft to clear below grade obstructions, installation of 208 HZ-M king piles, 419 AZ and PS steel sheets for the sheeting wall system, 2,500 LF of walers, and 191 tie-rods anchored to 381 H-pile dead men piles. Other work consisted of pipe jacking, mass-excavation and backfill, hydro-demolition of the existing concrete cap, replacement of existing cap with a new cast in place concrete cap, four-foot diameter drilled caissons, toe-pin anchors, railroad construction to extend an existing rail line into the port, underwater anodes, fender system, marine bollards, and roadway reconstruction.

Manafort served as Prime Contractor for the project, self-performing most of the work. All work was completed safely, on time, and under budget.
