The Generator Building Retrofit Project at Harbor-UCLA Medical Center involves the replacement and modernization of the existing generator switchgear and associated electrical infrastructure to ensure reliable emergency power distribution for the new Inpatient Tower (IPT) and Central Utility Plant (CUP). The project is a multi-increment, multi-phase HCAI-regulated construction effort, requiring careful shutdown coordination, phased implementation, and compliance with incremental Temporary Interim Occupancy (TIO) approvals. Scope includes, but limited to, installation of new 12kV switchgear, conduit and ductbank infrastructure, seismic upgrades, and system commissioning, with stringent requirements for continuity of hospital operations, impact mitigation, and regulatory compliance. The 12KV Switchgear and associated SEL relays and controllers as noted on the drawings are Owner Furnished-Contractor Installed. The project also includes the installation of two new fuel tanks to meet the HCAI NPC-5 requirements.
