Attachment C - Drawings.pdf

These are engineering design drawings for an electrical upgrade project at NY Harbor Healthcare Center, VA Brooklyn Campus. The project involves upgrading the life safety and critical branch electrical distribution system across Building 1, a multi-story healthcare facility located at 800 Poly Place, Brooklyn, NY 11209. Project number 630A4-16-430 comprises Task Orders 1, 2, and 3 for partial installation work.

The drawings provide comprehensive electrical design documentation including partial floor plans for the fifth through nineteenth floors and basement levels, showing the installation of new life safety panels, transformers, and branch circuits throughout the facility. Key components specified include forty-five 45kVA dry-type transformers (designated T-LS-B-1 through T-LS-16-1) serving 208Y/120V life safety loads, multiple 480Y/277V power panels with ratings ranging from 70A to 250A, automatic transfer switches (ATS-LS1 and ATS-LS2 rated at 260A), and associated emergency lighting and control circuits. The work requires disconnection and rerouting of existing life safety branch circuits from conventional panels to dedicated life safety distribution panels, with all work scheduled for evening and night shifts to minimize facility disruption. Panel schedules, one-line diagrams, and transfer switch specifications are included, along with detailed drawing notes addressing suspended ceiling coordination, floor penetration sealing for two-hour fire ratings, temporary lighting provisions during changeovers, and material removal and replacement requirements. The design incorporates LED lighting fixtures and comprehensive life safety circuit protection throughout the campus infrastructure.
