22x34-Loudon-Contract-5-Drawings-Addendum-3.pdf

This is an addendum file containing technical drawings for SEPTA's (Southeastern Pennsylvania Transportation Authority) Contract 5 Traction Power Substation Rehabilitation Program, specifically focusing on the Loudon substation as part of a larger project encompassing Broad, Loudon, Park, and Castor substations. The drawings document the engineering specifications and construction details for the rehabilitation work, which includes replacement of 13.2kV and 12kV switchgear, DC rectifier systems (750VDC and 600VDC), transformers, protective relays, station batteries, SCADA systems, HVAC improvements, fire protection and alarm systems, lighting, and electrical distribution infrastructure. The project requires completion of final design from 50% specifications and encompasses environmental remediation including asbestos removal, lead paint abatement, contaminated soil remediation, and PCB surveys across multiple building levels (basement, first floor, mezzanine, and roof). The two-step procurement process includes a pre-qualification meeting on June 10, 2026 via Microsoft Teams at 9:00 AM, mandatory site visits on June 11-12, 2026, and RFQ proposals due July 15, 2026 at 11:00 AM, with work to be completed within 2,035 calendar days from Notice to Proceed.

The project requires 5% bid security and 100% performance and labor/material payment bonds, with the contractor required to self-perform at least 20% of work. All steel products must comply with Pennsylvania's Steel Products Procurement Act and federal Buy America requirements. SEPTA encourages disadvantaged business enterprise (DBE) participation in accordance with 49 CFR Parts 26.39 and 26.51, though no specific DBE goal is mandated. Bidders must submit comprehensive qualifications including SF 330 forms, three years of audited financial statements, letters of commitment from bonding and insurance companies, detailed CPM schedules, and demonstrate team qualifications covering project management, design management, traction power integration, site supervision, safety, QA/QC, environmental compliance, and communications. Evaluation criteria in descending order of importance are team qualifications and project management, experience, understanding of schedule constraints, project approach addressing staging to minimize impacts to revenue service, and financial/project surety. Bids remain firm for 90 days from opening, with awards made to the lowest responsive, responsible bidder based on combined pricing across four parts organized by construction trade.
