Summary

This is an Addendum 5 drawing set for the Broad Roof Replacement component of SEPTA's (Southeastern Pennsylvania Transportation Authority) Traction Power Substation Rehabilitation Program – Contract 5. The file contains architectural and structural drawings for roof replacement work at the Broad Street substation, one of four substations (Broad, Loudon, Park, and Castor) included in this rehabilitation program. The drawings detail roof system specifications, structural modifications, and construction details required to complete the roof replacement as part of the broader substation modernization effort. This addendum supplements the 50% design documents that contractors will be required to complete as part of the design-build scope, which encompasses replacement of electrical equipment (13.2kV and 12kV switchgear, DC rectifiers, transformers, protective relays, batteries), HVAC improvements, fire suppression systems, SCADA integration, and environmental remediation work including asbestos removal and lead paint abatement across all four substations over a 2,035-calendar-day contract period.

The project is being procured through a two-step federal construction procurement process, with RFQ proposals due July 15, 2026 at 11:00 AM, a pre-qualification meeting scheduled for June 10, 2026 via Microsoft Teams at 9:00 AM, and mandatory site visits on June 11-12, 2026. Contractors must perform at least 20% of work with their own forces and maintain continuous traction power service during phased rehabilitation. All steel products must comply with Pennsylvania's Steel Products Procurement Act and federal Buy America requirements. Bidders must provide 5% bid security and 100% performance and labor/material payment bonds, with bids remaining firm for 90 days from opening. While no specific DBE goal is mandated, SEPTA encourages disadvantaged business enterprise and small business participation in accordance with 49 CFR Parts 26.39 and 26.51.
