Emergency Generator Replacement
Tighe & Bond was selected through a public request for the qualification process to provide on-call mechanical, electrical, plumbing, and fire protection engineering services for four years at the University of Connecticut (UConn). As part of this on-call agreement, we have provided engineering design services for the emergency generator replacement at the Atwater Lab.
Generator Removal / Feeder Installation
The existing life safety generator and distribution equipment is original to the facility construction and is beyond their useful life. The University requested that the existing generator be removed and the building be connected to the campus cogeneration electrical distribution system. The cogeneration source of power was extended from the existing draw out switchgear located in the basement of the adjacent chemistry building.
Tighe & Bond installed a feeder from the existing cogeneration switchgear in the basement of the chemistry building across a driveway and was brought into the basement of the Atwater Lab Building. The cogeneration feeder in the Atwater Lab basement was separated into an NEC 700 code-compliant emergency branch and a 702 Optional Standby Branch. The NEC 700 distribution system backed feeding existing loads. The NEC 702 Optional Standby distribution was included for future owner-selected load.
Tighe & Bond provided an opinion of probable construction cost (OPCC), bidding phase services, and construction administration services for this project.
