1. Project Overview This scope of work details the requirements for a qualified electrical contractor to perform a complete rewiring of a three-story residential property owned by the Independence National Historic Park Service. The work will include removal of all existing wiring, installation of new dedicated circuits, labeling, and restoration of affected surfaces, ensuring compliance with current safety and code standards.

2. Location 423 Locust Street, Philadelphia, PA 19106. The property is a three-story historic home under the jurisdiction of the Independence National Historic Park Service.

3. Contractor Responsibilities

· Open walls on all three floors as needed to access existing electrical wiring.

· Remove all old wiring from the electrical panel to outlets, ceiling-mounted lights, and light switches.

· Run a dedicated 12/2 wire to one outlet in each room; additional outlets in each room shall be wired in parallel from the dedicated outlet.

· Install dedicated 12/2 wire from the electrical panel to each light switch; run 12/2 wire from each light switch to the ceiling-mounted light in each room.

· Where 3‑way or 4‑way switching is required, run new 12/3 wiring from the breaker panel to the switch locations. Replace existing 3‑way or 4‑way switches with new devices. From the final switch in the switching sequence, run new 12/3 wiring to the ceiling‑mounted light fixture.

· Replace all existing electrical outlets and light switches with new 20‑amp rated outlets and switches throughout the property.

· Install two single 20 amp breakers per room: one breaker for outlets, one breaker for lights. Outlets and lights shall not share a breaker.

· Install 20 amp GFCI outlets around sinks in kitchen, bathrooms, and in all outside areas.

· Run new dedicated 12/2 wire to the emergency switch of the gas furnace and new 10/2 wire to the condensing unit, using outdoor-rated wire or protecting with rigid conduit, PVC conduit, or seal tight as required.

· Identify and label each breaker at the electrical panel according to the circuit controlled.

· Hire and coordinate with a subcontractor to replace and patch all drywall opened during electrical work.

· Ensure dedicated circuits for refrigerator, stove, garbage disposal, furnace, and condenser unit (no shared circuits).
