About this file
This is a Scope of Work specification document for the City of Cumming Department of Utilities in Georgia for the Smithdale Heights Water Booster Station project. The project requires the procurement and installation of one factory-assembled, diesel-powered emergency standby generator set rated at 40 kW with a standby voltage of 277/480 VAC, three-phase, 4-wire configuration, and 60 Hz frequency. The generator must be new, factory-tested, and listed for emergency standby service, complete with a weatherproof aluminum enclosure, sub-base fuel tank with 24-hour fuel capacity, automatic transfer switch rated at 125 amps at 480 VAC, and associated controls. The equipment must comply with U.S. EPA Stationary Emergency requirements, UL 2200 listing, NFPA 110 Type 10 Level 1, EPA Tier 3 emissions standards, and ASCE 7-10 wind loading requirements with a 180 MPH wind load rating. Bids are to be submitted to the City of Cumming Department of Utilities, 4th Floor Front Desk, 100 Main Street, Cumming, Georgia 30040.
The generator specification includes an electronic isochronous governor, brushless alternator with Class 105C insulation and Increased Motor Starting capability, sound-attenuated enclosure meeting Sound Level 2 attenuation standards, dual-wall regional steel fuel tank with high and low fuel level switches, digital controller with programmable inputs and outputs, 250 Amp 3-pole circuit breaker, 12-volt starting battery system with 6 amp regulated charger, and MODBUS TCP communications module. The manufacturer shall provide a two-year comprehensive warranty commencing upon successful startup and commissioning, factory startup, operational testing, maintenance training, and factory load bank testing. Additional items to be furnished and installed by others include generator unloading, concrete pad placement, fuel piping, exhaust piping, electrical conduit and wiring, NETA testing, and a maintenance agreement. Equipment pricing excludes sales tax and must include shipping; current lead times are to be confirmed by the manufacturer.
