Progress on the Port of Charleston's Navy Base Terminal has reached another milestone with the approval of the next major construction project.

The South Carolina Ports Authority (SCPA) Board has approved the $42.7-million contract, which includes the placement of fill material on portions of the landside of the terminal and along the already completed 5,000-foot-long containment wall structure, which was constructed toward the shipping channel. The facility represents the only permitted new container terminal currently under construction on the U.S. East and Gulf coasts.

"The completion of the Navy Base Terminal, along with the Charleston Harbor Deepening Project, demonstrates that South Carolina understands what the industry's future demands are, and we will be ready to meet them," said Bill Stern, chairman of the SCPA Board. "The new terminal and a deepened harbor are both essential to fulfill our mission of economic development and serve our customers' needs for the foreseeable future."

The Board selected for the project Massachusetts-based Jay Cashman, which was the lead contractor on the demolition of the former Cooper River bridges, as well as one of the partners on the $44-million containment wall project for the Navy Base Terminal.

Starting next month, crews will relocate approximately 1.75 million cubic yards of dredged material from Daniel Island to the terminal site by water, placing the fill behind the containment structure and on portions of the upland area. The crews also will consolidate the upland area of the site by installing approximately 5.7 million linear feet of vertical wick drains and surcharging the area to stabilize the site and prepare it for construction.

The project is expected to run through January 2014, overlapping with the next major fill contract, which is slated to begin late next year. At build out, the new, 280-acre container terminal will increase the Port of Charleston's container capacity by 50 percent.
