This is an addendum drawing document (Addendum 3) for SEPTA's Traction Power Substation Rehabilitation Program Contract 5, specifically detailing the Park Substation at 22nd Street and Indiana Avenue in Philadelphia, Pennsylvania. The drawings, stamped by Berg Pipe Corp and dated with revisions through May 2025, provide detailed architectural, structural, electrical, and civil engineering specifications for rehabilitating the Park traction power substation as part of a larger four-substation modernization project along SEPTA's Broad-Ridge Spur line. The document includes site plans, floor plans for basement through roof levels, structural framing details, steel gantry modifications, equipment layouts for 13.2kV switchgear and DC rectifier systems, HVAC improvements, fire protection systems, foundation details, and coordination drawings showing existing conditions and proposed modifications across multiple building levels.

The drawings incorporate environmental remediation work including asbestos abatement areas, lead paint removal zones, and contaminated soil handling procedures, with specific callouts for hazardous material locations throughout the facility. Construction phasing is detailed to maintain continuous 600VDC traction power service during rehabilitation, with temporary power provisions and staged equipment replacement sequences clearly marked. The plans reference compliance with Pennsylvania Steel Products Procurement Act and federal Buy America requirements, include notes for coordination with adjacent SEPTA revenue service operations, and specify quality control inspection points for all major systems including SCADA integration, electrical distribution, communications infrastructure, and structural steel modifications to existing gantries supporting overhead contact systems.
