From the Team

Bob Williams"The sheet metal cost for the service shop, designed by the first engineering team, far exceeded the owner's budget.  Williams Notaro took over the design and converted the ductwork in the shop to fabric ductwork, saving the client over $100,000 getting the project back on track."

Cowles Ford Dealership Renovation

Williams Notaro provided MEP engineering services to completely renovate an existing 67,500 square foot lumber yard from the 1980's to accommodate a modern, full-sized Ford automobile dealership.  To maintain budget constraints, the existing roof top units were re-used to provide zone air conditioning.  The ventilation system for the new service bay area allows for 24-hour operation, independent from the HVAC system serving the remainder of the dealership.

For the service shop, fabric duct systems were designed and incorporated into the open ceiling architecture to reduce the structural roof load and provide uniform air distribution in the large open areas.  Additionally, a custom-designed, double deck, 40,000 CFM energy recovery makeup air system, with a heat recovery wheel, packaged refrigeration scroll compressors, and indirect gas heat, reclaims up to 60% of the energy used to heat and cool the service shop.
