RFP 50067 ¿ Track Isolation Integrity Monitoring System

The Metropolitan Atlanta Rapid Transit Authority (MARTA) is seeking proposals for RFP P50067, a comprehensive Track Isolation Integrity Monitoring System (TIIMS) project. The procurement involves the complete design, installation, testing, and commissioning of a sophisticated monitoring system with both hardware and software components to measure and monitor voltage across track segments at Traction Power Substation (TPSS) locations. The system's primary objectives include continuous monitoring of stray current for corrosion control, active voltage tracking from track to ground, and providing automated fault detection and reporting capabilities. The project will be implemented across MARTA's 48-mile track system covering 38 rail stations, with a total contract duration of 1,825 days. Key deliverables include 52 Voltage Limiting Devices, data communications electronics, signal and control cables, cabinets, patch panels, and AC power distribution, along with two years of support including five VLD spares. Critical procurement dates include a virtual pre-proposal conference on February 12, 2025, at 10:00 a.m., a question submission deadline of February 20, 2025, at 12:00 p.m., and proposal submissions due March 26, 2025, at 2:00 p.m. Evaluation criteria will be assessed in order of importance: Activation, Migration and Service Delivery Strategy; Overall Experience and Qualifications; Key Personnel; Price Proposal; Financial Stability and Capabilities; and Equal Employment Opportunity/DBE response.

The solicitation includes a 25% Disadvantaged Business Enterprise (DBE) participation goal and is federally funded, which subjects the contract to Buy America requirements. Contractors must provide a full-time scheduler with a minimum of five years of Primavera P6 experience and large capital project scheduling expertise. Progress payments will be structured with 25% disbursed upon acceptance of the baseline schedule, with the remaining balance prorated over the contract duration following monthly schedule updates. The project requires extensive security and compliance measures, including adherence to information security requirements, train control and SCADA security protocols, and comprehensive data protection standards aligned with NIST frameworks. While no specific total contract value is explicitly stated, the detailed scope and multi-year implementation suggest a significant investment in infrastructure improvement. Potential bidders must demonstrate robust technical capabilities, extensive transit system experience, and the ability to integrate advanced monitoring technologies into MARTA's existing infrastructure while maintaining strict security and performance standards.
