Bergen Point Project Awarded UCA Project of the Year

Philadel­phia – The Underground Construc­tion Association (UCA) awarded the Bergen Point Southwest Outfall Replacement project in Suffolk County, NY with the 2022 Project of the Year Award at the North American Tunneling Conference award ceremony in June of 2022. This award is presented to an individual or group “that has shown insight and under­stand­ing of underground construc­tion in a significant project, which may include practices, developing concepts, theories, or tech­nolo­gies to overcome unusual problems within a project, resulting in little to no outstanding issues.”

CDM Smith provided design and construc­tion management services from the initial assessment of the existing outfall, geot­ech­ni­cal engineering inves­ti­ga­tions across Great South Bay, shaft designs using ground freezing, tunnel design and inspection, and worked closely with the contractors in an innovative approach to the tunnel machine launch using micro-tunneling techniques followed by conversion to full tunnel construc­tion.

This award was presented for projects with construc­tion valued between $50 to $500M. Geot­ech­ni­cal, envi­ron­men­tal, and construc­tion risk assessments guided the team to an innovative tunneling approach of sewer pipe excavation depths reaching 100+ feet for Bergen Point, which treats approx­i­mately 40.5 million gallons of wastewater per day. The firm assisted in the replacement of a preexisting, failing 72-inch diameter, 14,200-foot-long sewer outfall pipe located under Great South Bay.
