ZOFS provided Resident Engineering Inspection Services on this $80 million capital infrastructure project, which involves the installation of 16'x8' combined box sewers, regulator chamber on 48" interceptor (including a sluice gate), tide gate chamber, and fourteen other chambers in Southeast Queens. The project required the construction of a Regulator Chamber connecting a double barrel box combined sewer to the existing 48" interceptor sanitary sewer. Prior to starting this operation, the field team ensured the Contractor's surveyor provided a Preconstruction Report, identifying underground utilities and their impacts, connections to existing sewers and manholes, geometry, structural integrity of all structures to be modified, fluming system, dewatering system, support of excavation, and MPT plans.
A tide gate chamber was added to the project scope. When reviewing field conditions for the Regulator Chamber, it was determined that there wass potential for the tide to fill the combined sewer and impact the interceptor sewer. Field staff including Assistant Resident Engineer Reza Mousavian coordinated with NYCDDC, NYCDEP, & the Contractor to develop a tide gate chamber and its gates. The street restoration and resurfacing portion of the project meticulously adhered to DOT Specifications, ensuring the completion of roadway markings catering to both vehicle and pedestrian needs. A comprehensive overhaul encompassed the renewal of 77,889 square feet of sidewalk and 14,105 linear feet of curb infrastructure, aligning them seamlessly with the freshly resurfaced road. Community outreach was a major proponent to the project's success, with MPT plans to keep a portion of the street open and coordinating with local businesses. Notably, all reconstructed curbs were designed to comply with ADA standards, reflecting a commitment to accessibility for all members of the community.
