OGS Herkimer Flood Protection Project

Herkimer, New York

Project Overview

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.

Project Details

MFS’s Site/Civil team prepared the erosion and sediment control (ESC) plans for both pre- and post-construction of the monolith structure. These plans were developed in compliance with the New York State Standards & Specifications for Erosion & Sediment Control and were carefully coordinated with the construction staging plans. The final submission included detailed drawings of the Soil Erosion & Sediment Control Plan, control details, and construction notes and specifications.

MFS also developed the Work Zone Traffic Control (WZTC) plans to manage traffic during the demolition, excavation, and installation phases of the monolith structure. Given the active four-lane road on Mohawk Street, MFS prepared a staged traffic control plan that ensured minimal disruption. The plan included three phases: the first phase addressed northbound lane closure, the second phase involved southbound lane closure, and the third phase encompassed closures in both directions. The WZTC plans adhered to New York State Department of Transportation (NYSDOT) standards and the Manual on Uniform Traffic Control Devices (MUTCD). These plans outlined the placement of advanced signage, construction drums, barriers, and other site-related equipment.
