88th Medical Center

The Air Force Medical Support Agency (AFMSA) determined that the 88th Medical Group have portions of the Chilled Water System, Building Envelope Systems and several interior medical spaces serving the 88 MDG that are no longer efficient or have deteriorated to where it is no longer serviceable, reliable, or energy efficient, and could compromise medical treatment to its patients.


    • Location:  Wright Patterson AFB, OH
    • Project Size: 16,000 SF
    • Cost:  $25,000,000
    • Facility Type: Healthcare
    • Owner: U.S. Air Force
    • Services:  Electrical and Mechanical/ Plumbing Engineer

The Government required a single “turn-key” performance-based project replacing controls, cooling towers, electrical service equipment, designing a new chiller plant, and renovating chilled water system to provide a 15-year life extension to the facility mission.  Dell Consulting design engineers fully investigated the existing conditions and requirements associated with healthcare system to ensure that any planned modifications met or exceeded these requirements with a comfortable margin of excess/redundant capacity.  The recommendations included conceptual drawings, narratives of the proposed solution, estimates of the execution timeline of work, and a plan to minimize the adverse impact of the work on the occupants and their operation.

This project included a 16,000 sq. ft. renovation of the Hospital’s main lobby, pharmacy and pediatric suite as well as major modifications to the hospital’s central energy plant. The three failing 4,160V chillers were replaced with new 1,500 Ton 480V/3-phase chillers arranged in an N+1 configuration. The associated hydronic piping, pumps and cooling towers were also replaced.

A new 4,000A Main-Tie-Tie-Main switchgear was provided to serve the new chillers and cooling towers. The remaining central energy plant equipment was re-fed from a new Main-Tie-Main motor control center. The new electrical distribution system was designed to allow for downtime for maintenance of any piece of equipment without impacting hospital operations. All work in the energy plant was performed without impacting the operation of the hospital.

Extensive renovation designed to be accomplished in coordination with ongoing facility operations. All designs, system modifications, and installation of new equipment and materials will improve operations, reduce costs, increase reliability, provide for ease of maintenance, and extend the operational life of the system.

Dell Consulting replaced controls, cooling towers, electrical service, designed a new chiller plant, renovated chilled water system and various buildings.
