Karpinski Engineering was the prime associate for implementing MEP infrastructure upgrades within Rhodes Hall (including 12 floors, plus penthouse and tunnels), Doan Hall (including 12 floors, plus penthouse and tunnels), and the James Cancer Hospital at The Ohio State University’s Wexner Medical Center.
The $42-million project included the following upgrades:
Replacing vintage building sanitary mains in the Doan Building tunnel and phasing the process so that only one riser was inactive at a time
Connecting interim emergency chilled water where existing chillers in Rhodes, Doan, and James Buildings were unreliable
Replacing approximately 300,000 cfm of air-handling units and adding approximately 100,000 cfm of capacity for future use by the Medical Center. This required modifying designs of building additions
Converting two large, dual-duct distribution systems to systems that utilize variable- air-volume and terminal units with hot water reheat. This required a phased and systematic approach, so that an excessive amount of patient rooms were not rendered unavailable at any one time
Connecting vintage unitary chilled-water systems in each building to the Central Plant chilled water through plate-and-frame heat exchangers. This required an addition to the James Cancer Center to house equipment
Replacing Rhodes Hall’s central hot water heating and steam conversion systems
Removing and replacing antiquated automatic transfer switches, which were no longer code-compliant
Enhancing and extending the essential emergency system
Enhancing and/or replacing emergency distribution serving mechanical equipment
Replacing the fire pump controller to allow pump connection to emergency power
This has been one of the most extensive projects that Karpinski Engineering has coordinated directly with an Owner. While complex, it was essential for facilitating future renovations and additions to the Wexner Medical Center campus. Karpinski Engineering worked closely with the space users, construction manager, and commissioning agent so that occupied spaces remained operational while new systems were brought online and old systems were decommissioned and removed.
