A/Z provided specialty construction services for Yale-New Haven Hospital’s Central Sterile Supply Renovation Project. The intent of this expansion project was to increase the capacity of the central sterile supply department to support the future addition of a dozen operating rooms. This work was executed utilizing eight phases of construction to ensure the central sterile supply department operations were not disturbed. New utilities installed to support the new equipment include high-pressure steam and condensate piping, pure water system and piping, non-potable hot and cold water piping, air piping, and new drainage piping.
