Hospital Central Sterile Suite
C&S provided HVAC, plumbing, electrical and life safety engineering services for the full renovation of the central sterile suite at Buffalo General Hospital. A major design challenge was ensuring that sterile processing remained operational throughout construction. If cleaning and sterilization operations became limited, the hospital’s surgical capacity would be compromised.
Construction was split into four separate phases to accommodate the needs of occupied clinical spaces, and maintain proper air pressure relationships throughout the project. Weekly coordination meetings were held with all stakeholders during construction to minimize impact on central sterile, and on adjacent spaces also undergoing significant renovation.
Initial design included extensive field investigation of existing mechanical, electrical and life safety systems. Existing documentation was reviewed, including balancing and testing reports and owner testing of air handling equipment.
Sterilizers are served by steam provided from the sub-basement. Designing and installing steam and condensate piping systems in the sub-basement ceiling was a priority because of another construction project in the same area. Careful coordination in the sub-basement was also required for floor drain relocations, and compressed air routing.
An additional challenge was modernizing HVAC supply. Shutting down the existing air handler to replace it was not an option due to the need to maintain the existing sterile suite. Instead the air handling unit base was refurbish (due to corrosion) and a variable frequency drive added. All new temperature control work is electronic DDC type extended from the existing hospital’s control system.
