This is an electrical enlarged plan drawing for the basement of Buffalo Public Schools (BPS) 97 Harvey Austin Elementary School, prepared by Buffalo Engineering, PC, as part of a fire pump replacement project affecting two critical facilities: BPS 99 Stanley M Makowski Early Childhood Center and BPS 97 Harvey Austin Elementary School, both located in Buffalo, New York. The drawing, dated August 29, 2025, illustrates both existing and new electrical configurations in the basement, detailing the removal and installation of fire protection system components. Key work includes disconnection and removal of an existing 50-horsepower 480-volt 3-phase fire pump (58.5 FLA) and associated jockey pump controller, along with their respective transfer switches and feeders, and replacement with a new 60-horsepower 480-volt 3-phase fire pump (77.0 FLA) and upgraded controllers. The new jockey pump will operate at 1 horsepower 480-volt 3-phase (2.1 FLA), a reduction from the existing 2-horsepower unit (2.5 FLA).

The project requires installation of a new 450-ampere 3-phase circuit breaker in the existing switchboard to serve the new fire pump, with all wiring and conduit work meeting specific fire-resistance ratings of not less than 2 hours as verified through Detail #2 on Drawing E300. Demolition notes specify disconnection of existing mineral-insulated cables and branch circuit conduit, with rework and extension of existing feeder conduit from the generator and fire alarm control panel to the new controller and transfer switch. The work maintains connection to existing 480/277-volt and 208/120-volt main distribution switchboards and existing generator backup systems for emergency operation capabilities. The electrical plans form part of the comprehensive fire pump replacement scope required to address aging equipment that has exceeded its expected operational life and ensure continued compliance with local fire codes and insurance requirements for these critical school facilities.
