225DO005_West_Corridor_drawings_flattened_-_Bridge_Maintenance_Services.pdf

This is a technical drawing file for bridge maintenance services issued by the Regional Transportation District (RTD) in Colorado. The drawings provide detailed engineering specifications and visual documentation for RTD's West Corridor bridges that require ongoing maintenance services under the Bridge Maintenance Services contract opportunity. The maintenance work encompasses both cyclic activities such as vegetation control, general cleaning and power washing, drain cleaning, expansion joint cleaning, and sealing/waterproofing, as well as as-needed repairs including concrete repair, expansion joint replacement, bridge connection maintenance, bearing lubrication, bolt tightening/replacement, coating application for corroded elements, sign installation, erosion repair, utility attachment maintenance, and fence replacement.

The contract includes a 15% Small Business Enterprise (SBE) set-aside requirement and covers all RTD-owned bridges, adjacent and attached structures, and culverts throughout the transit system. The scope extends to urgent work on roadway bridges that may affect rail operations, including bridges owned by other entities within RTD's operational area. Work will be executed on a work order basis, allowing for flexible response to both scheduled maintenance needs and emergency repairs as defects are discovered or occur throughout the contract term.
