Ross & Baruzzini served as the prime engineer for a new single-story, 22,000-sf fleet garage (with storage mezzanine) at the Ameren Dorsett Complex in St. Louis County to establish design criteria required for an efficient, safe, durable, and sustainable facility. The facility is to be used to maintain fleet vehicles (service equipment, trucks, trailers, boom trucks, etc.) used by Ameren to maintain their electrical plants and electrical distribution network throughout the region.
The fleet service garage is approximately 22,000 sf and contains an administration area complete with offices, breakroom, conference room, toilet rooms with lockers and showers, and parts storage. The building also has a storage mezzanine above the administration area, six service bays that can serve up to two vehicles in each bay, a wash bay, a fabrication shop, a lube room, and a compressor room. The design team coordinated with crane, lift, and lube vendors to engineer two 3-ton cranes in each service bay, in-ground lifts in three service bays, and fluid dispense reel systems containing hydraulic fluid, diesel oils, and standard engine oil dispensers in each bay.
The mechanical system included HVAC systems for the shop and administration areas. The administration area was designed utilizing a variable refrigerant flow (VRF) type system. The shop area was designed using a heat pump type system designed for large open spaces like shops or warehouses and quartz infrared heaters for additional heat. The shop area also included ventilation for the general shop and for vehicles to run in the shop.
The plumbing system included hot water heaters to serve the showers and sinks in the administration area and shop and a dedicated hot water system for the steam power washer in the wash bay. The plumbing system also included two air compressors to provide compressed air quick connect outlets throughout the shop and on cord reels. Fluid tanks were designed in the lube room to pump diesel engine oil, gas engine oil, and hydraulic fluid to reel dispensers in each service bay. Floor drains were designed in the shop and were drained to an underground oil interceptor/separator.
The electrical system included power distribution for an all-electrical building, including distribution to receptacles, welder receptacles, fabrication equipment, cord reel outlets, LED lighting, and mechanical and plumbing equipment connections. The electrical design also included emergency generator backup for a majority of the shop area and administration area.
The telecommunications and security systems design included data and voice outlets, horizontal cabling, racks, patch panels, audio-visual in the breakroom, video surveillance, recording equipment, and access control for all entries into the facility.
