This is a Work Order Quantities document for the Regional Transportation District (RTD) in Denver, Colorado, detailing bridge maintenance services under contract 225DO005. The document specifies Work Order #1 scope for four West Corridor Light Rail Transit bridges: LRT-COLFAX, LRT-6TH-INDIANA, LRT-WADSWORTH, and LRT-CML. Maintenance activities include expansion joint cleaning (ranging from 40 to 140 linear feet across bridges), power washing (ranging from 13,380 to 30,640 square feet), deck sealing with preparation (matching power wash quantities), debris removal from drains (40 to 126 linear feet), and crack sealing for fissures wider than 1/8 inch (1,000 to 2,000 linear feet). Additional work includes concrete patching at LRT-6TH-INDIANA (800 square feet), tightening anchor bolt nuts, drain downspout extensions, bird netting cleaning, and vegetation removal. Each work order location includes traffic control, permits, and mobilization costs listed as lump sum items. The overall contract is structured as a three-year term with two optional one-year renewal extensions, with RTD anticipating final contractor selection by September 18, 2025, and bids due September 11, 2025.

All line items in Work Order #1 are listed at zero unit costs, indicating this document serves as a quantities template rather than a priced bid. The work will be performed on a fixed-price basis with payments made according to completed quantities multiplied by contracted unit prices. The solicitation includes a mandatory 15% Small Business Enterprise (SBE) set-aside requirement, and bidders must provide bid security equal to 5% of their bid amount and demonstrate good faith efforts to meet SBE participation goals to be considered responsive. Contractors must demonstrate a five-year track record in bridge maintenance, comply with Federal Railroad Administration and Federal Transit Administration regulations, complete RTD's On Track Safety Training, and obtain necessary Right-of-Way Access Permits and Building and Grounds Access Permits. Work must be capable of execution during nights, weekends, and off-peak hours to minimize disruptions to light rail and commuter rail operations, which involve overhead catenary systems operating at 750 volts DC and 25,000 volts AC respectively.
