New Bedford Marine Commerce Terminal
|Client:||Massachusetts Clean Energy Center|
|Project Date:||March, 2013 - December, 2014|
Cashman and our joint venture partner Weeks NB were among the firms contracted to perform dredging and marine construction to provide a multi-purpose facility designed to support the construction, assembly, and deployment of offshore wind projects, as well as handle bulk, break-bulk, container shipping and large specialty marine cargo. The first of its kind in North America, the Terminal was engineered to sustain mobile crane and storage loads that rival the highest load-bearing ports in the nation (loads of 4,000 pounds per square inch).
- Cashman provided 910,000 cubic yards of dredging, including clean-up of 250,000 cubic yards of PCB-contaminated sediment.
- Constructed a Confined Aquatic Disposal (CAD) cell requiring 350,000 cubic yards of dredging.
- Dredged to -32 feet into rock in front of new bulkhead.
- Mined 250,000 cubic yards to deepen the berth for reuse within the new constructed containment wall.
- Conducted drilling and blasting for 25,000 cubic yards of rock.
- Installed 13 major cofferdam bulkhead sheetpile cells with 60-foot diameters.
- Managed installation of 1,000 feet of linear bulkhead and wharf, which was covered by 6,000 cubic yards of cast-in-place concrete.
