Berth IV Seagirt Marine Terminal

Piers & Bulkheads, Design BuildBerth IV Seagirt Marine Terminal
Owner : Ports America
Location : Baltimore, Md

McLean partnered with Moffatt & Nichol to delivered this design build project to Ports America Chesapeake as part of a public private partnership between Ports America and Maryland Port Administration. This was project was located at MPA’s existing Seagirt Marine Terminal in Baltimore, Maryland.

The Construction of Berth IV at the Seagirt Marine Terminal included the demolition of 1,125 linear feet of 65 foot diameter steel cofferdam retention structure along with an existing concrete dolphin. The new construction for the 1,225 linear feet wharf was founded on a combination of
24-inch and 30-inch prestressed concrete piles. This project featured 11,950 cubic yards of cast-in-place concrete that included pile caps, crane rail beam, precast fascia and deck topping. Our design build team value engineered the use of precast deck slabs in lieu of a complete cast-in-place deck for efficiency and cost as well as the safety of our employees that would have been required to navigate 153 feet back from the face of the berth underneath the deck of the structure to strip the underside of the deck forms. These crews would have been subject to the dangers of swells and waves while working in a confined space. This project also included 310,000 cubic yards of dredging.
Ports America had a very aggressive timetable and large liquidated damages for the completion of this project. McLean took an aggressive approach to the construction schedule working 12-hour days, 7 days a week to complete this project on-time.
