MFS Consulting Engineers & Surveyors, DPC provided professional engineering services in support of the New York State Office of General Services and the New York Department of Environmental Conservation's Flood Closure Structure No. 2 Replacement Project, located on Mohawk Street in Herkimer, New York. This project was situated beneath the I-90 New York State Thruway, bordered by Fifth Avenue to the north and Canal Access Road to the south. The scope of work included the design and construction of a new flood closure structure along Mohawk Street. The proposed flood closure structure was to include a new gate system across Mohawk Street, beneath the southern side of the I-90 Thruway overpass bridge, which was scheduled for replacement under a separate contract. The construction of the flood closure structure was planned to proceed following the I-90 bridge replacement. The design encompassed monolith work, cut-off sheet piling, closure walls, utility relocation, and roadway restoration.
