This is a set of electrical installation drawings and schedules for the "Upgrade Life Safety/Critical Branch Electrical Distribution" project at NY Harbor Healthcare Center, VA Brooklyn Campus, located at 800 Poly Place, Brooklyn, NY 11209. The project involves upgrading life safety and critical branch electrical systems across Building 1 (Project Number 630A4-16-430).

The drawings include partial floor plans for the fifth through nineteenth floors, basement, and ground floor, showing electrical panel locations, life safety circuit installations, and equipment placements. The project encompasses multiple task orders with installation of new life safety panels (LS-H and LS-L series), transformers (45 kVA, 208Y/120V dry-type units), and branch circuits to support critical loads. Key electrical components include automatic transfer switches (ATS-LS1, ATS-LS2) rated at 260A, 480V, 60Hz; life safety panels at 125-225A ratings with 22kAIC interrupting ratings; and associated lighting and power circuits. Panel schedules detail circuit breaker configurations, transformer specifications, and lighting fixture schedules (LED industrial strips, 18W, 120V). The work requires evening/night shift execution, suspended ceiling tile removal and replacement, floor penetrations sealed for 2-hour fire rating, and coordination of exact routing in the field due to congested ceiling areas. Supporting one-line diagrams and schedules specify the campus electrical infrastructure including multiple switchboards (A-Board, B-Board), switchgear, and coordination with existing utility services and emergency generators. The project is designed by D2X Associates, with Ramboll serving as consultant and Engineering Solutions, Inc. providing engineering support.
