The scope of work encompasses comprehensive infrastructure upgrades including replacement of existing 84-inch DOW valves with two 72-inch jet-flow gates, installation of concrete-encased steel penstock liner extensions, construction of a reinforced concrete operator platform with hydronic heating and jib crane, electrical system upgrades featuring new control paneling and ultrasonic flow-meter installations, access road improvements, and erosion-control measures. The successful contractor must comply with all applicable federal, state, and local regulations including dam safety requirements and environmental permits already obtained by NHDES, while securing any additional permits necessary for project execution.
