Serving the St. Louis Region, Mid-Missouri and Metro East

The Hoffman Lofts and Greeley Lofts

Integrated Facility Services completed complex mechanical contracting projects to convert two historic buildings in downtown St. Louis into mixed-use lofts and commercial space. IFS provided design/build HVAC, fire protection and plumbing services as part of the $9.6 million renovation to convert the former Hoffman Produce Building, which was built in 1882, to serve the new uses of the 34,000-square-foot mixed-use building including more than 6,000 sf of commercial office space, 6,700 sf of retail space and 21 apartment units.

IFS also provided services as part of the $14 million Greeley Lofts renovation, which adds 36 one and two-bedroom apartments, more than 11,500 sf of commercial space within the 19th century-era, five-story building that was once home to Carlos S. Greeley’s grocery house.

Challenge

Working in a historic building to transform it to an entirely new use is a complex undertaking. Each unit had to have its own mechanical systems with extensive replacement of piping, ductwork and more to modernize and meet building codes. Primary challenges also included aesthetically routing the piping in an open ceiling and utilizing as much of the existing system while providing adequate coverage for the new occupancy requirements.

Solutions

To achieve optimal tenant comfort, IFS’ HVAC work included replacing all ductwork, installing heat pumps, air handlers, exhaust vents and electric heaters for the buildings including common spaces, public restrooms and the basement. Fresh air systems were installed to exchange stale indoor air and fresh, filtered air from outside and to manage the air exchange for comfortable temperature and humidity levels.

IFS’ fire protection system work included installing new fire pump equipment, wet fire sprinkler systems, and a new service to the building. Among other upgrades, fire sprinklers were relocated to accommodate the new walls and ceilings. The fire sprinkler systems were extended to Greeley Lofts’ rooftop entry. A 30-foot by eight-foot fire sprinkler pump room was constructed to accommodate the new exterior service, backflow, wet fire sprinkler risers and horizontal split case fire pump. Plumbing work included installing underground PVC piping and above-grade water risers and waste/vent stacks throughout, including service to the commercial kitchens. IFS roughed in water, waste and vent lines to the individual residences. In each of the apartment units for both buildings, IFS installed electric water heaters, bathroom and kitchen fixtures, a laundry box at each washer/dryer location and water, waste and vent stacks.
