GBA provided engineering design services for a replacement central plant for Riverside Medical Center, a 571,000-square-foot acute care hospital. The new plant includes steam boilers, boiler feedwater equipment, chillers, cooling towers, domestic water heaters, electrical service, and medical gas equipment. Scope consisted of 8,000 square feet of new plant space, as well as renovations to 5,000 square feet of existing space.

Central Plant Design

Riverside Medical Center is a 300-bed comprehensive hospital. The new central utility plant accommodates growth and addresses the need for equipment upgrades. The scope included the following major items:

  • New boiler plant consisting of four 350-hp steam boilers using natural gas with fuel oil backup, variable speed burner fans, and oxygen trim controls.
  • New boiler feedwater equipment, including reverse osmosis pre-treatment, condensate surge tank, and deaerator tank with variable speed feedwater pumps.
  • New domestic and laundry hot water heating systems, including water softening, instantaneous steam-to-water heat exchangers, recirculation pumps, and controls.
  • New steam distribution header and pressure-reducing stations.
  • New chiller plant consisting of one 1,000-ton centrifugal chiller with variable speed drive; two 500-ton rotary screw chillers with variable speed drives; and two 200-ton air-cooled scroll chillers for winter operation.
  • Chilled water distribution was converted to primary-secondary design and cross-connected to the Hospital’s East Tower chilled water system.
  • New medical vacuum system, including a quadraplex skid system with a 200-gallon receiver tank and controls.
  • New medical air system, including a triplex skid system with a 200-gallon receiver tank and controls.
  • New electrical service for the central utility plant, with dual utility feed and ATO gear, a 2,000 kVA utility transformer, and a 3,000-amp switchboard.
  • The original 500-kVA transformer and 2,500 -mp switchboard were replaced.
  • Upgrade of an existing 1,500 kW cogeneration plant, paralleling panel controls from analog to digital.
  • Replacement of all original central plant electrical motor control centers and distribution panels.
  • New emergency connections for roll-up steam boilers, chillers, and electrical generators.
