Electric Trolley Bus Traction Power Substation Design

The contract involves a multi-year project initiated by the Greater Dayton Regional Transit Authority to upgrade its Electric Trolley Bus system through the replacement and addition of traction power substations (TPSs). Spanning approximately five years, the project aims to modernize the electrical infrastructure critical for trolley bus operations. The procurement process is structured in two steps: initially, proposers submit technical qualifications, references, and related data for evaluation and ranking by an assessment committee; subsequently, the most qualified proposers receive an Invitation for Bid (IFB) to submit pricing proposals. The contract size is estimated to range between five million and fifteen million dollars, reflecting the scope and complexity of the electrical design and installation work. The solicitation, titled "Electric Trolley Bus Traction Power Substation Design," was posted in April 2025, with a response deadline set for mid-May 2025. The project encompasses detailed engineering requirements, including civil, mechanical, electrical, HVAC, plumbing, communications, and exterior improvements, as outlined in the comprehensive RFP document. The primary point of contact for inquiries is Deborah Howard, reachable via email and phone. The project emphasizes technical excellence and adherence to specifications, with the ultimate goal of enhancing the reliability and capacity of the transit authority’s trolley bus electrical system. Additional related documents, such as storm sewer specifications and training service scopes, provide context on the broader scope of infrastructure and operational improvements associated with the transit upgrade initiative.
