Tetra Tech provided USACE New England District with a 56,250 SF dewatering facility at New Bedford Harbor. We designed and built four buildings, including a main dewatering building, process building, load-out building, and support building. Our team coordinated design and construction activities with USACE’s engineering team to ensure successful project planning, execution, and partnering.

• Tetra Tech designed, built, and managed construction of the main Dewatering Building, a pre-engineered steel frame construction (approximately 165 ft x 270 ft. x 40 ft. high), and associated infrastructure, including water, sewer, storm drainage and electrical infrastructure.
• Main building components included a process building (165 ft x 180 ft, 29,700 SF); a load-out building (90 ft x 225 ft, plus a 60 ft x 60 ft, 23,850 SF bay); and support building (30 ft x 90 ft, 2,700 SF).
• A 1,700-ft-long rail spur, siding and associated switching equipment and weigh station were designed and built for efficient material transport off site and for future use by the city.
• Tetra Tech worked cooperatively with USACE and city stakeholders to provide a facility and infrastructure to meet the near-term needs of USACE and long-term needs of the city.Tetra Tech worked cooperatively with USACE and city stakeholders to provide a facility and infrastructure to meet the near-term needs of USACE and long-term needs of the city.
• During construction, three value engineering proposals were submitted to the USACE resulting in over $450,000 in savings to the project.

Safety Highlight. A full H&S program was implemented, and a Site H&S Committee of Tetra Tech staff, subcontractors, and trade craft workers was formed. All construction activities were completed without a lost time incident.
