Overview
Gedeon GRC Consulting served as the lead civil and traffic engineer in support of the Bay Park Conveyance Project (BPCP) — a Design-Build wastewater infrastructure improvement project under the Western Bays Resiliency Initiative. Spanning NY-27 (Sunrise Highway) between the Bay Park Sewage Treatment Plant and the Cedar Creek Water Pollution Control Plant, and the residential streets connecting the facilities to NY-27, the project aims to improve water quality and storm resiliency in Long Island’s Western Bays in Nassau County.
Scope of services
Gedeon GRC’s scope involved civil, traffic and roadway designs for the pumping station, shafts for micro-tunneling, and required utility and restorative work throughout the project area. The team developed a traffic management plan, including simulation analysis, to minimize disruption to traffic flow while maintaining and enhancing safety during construction. Additional elements included utilities, drainage, pavement marking, signage, traffic signals, Work Zone Traffic Control, erosion and sedimentation control, and Stormwater Pollution Prevention Plans. The design was performed on a fast-track schedule under a rigorous QA/QC program to ensure compliance with all codes, standards and specifications — with particular emphasis on the NYS Department of Environmental Conservation Stormwater Manual to minimize impacts on surrounding water bodies.
Innovation & coordination
The project’s use of micro-tunneling and slip lining to repurpose an existing aqueduct reduced project costs, schedule and impacts on the local community, residents and business owners. The work was coordinated with the NYS Department of Transportation, Nassau County Department of Public Works, NYS Department of Environmental Conservation and all impacted municipalities.
