About this file
Exhibit D is a technical specifications document for the Regional Transportation District (RTD) in Denver, Colorado, supporting the Ticket Vending Machine (TVM) Replacements project. The exhibit provides standard construction details for the removal and installation of 185 existing TVMs and deployment of 173 new units, including 113 replacements at existing locations, 54 installations along the East Colfax Bus Rapid Transit corridor, 1 unit at Civic Center Station, and 5 spare units, with an optional purchase of 6 additional units for Denver Union Station Bus Concourse. The document establishes technical requirements and procedures that contractors must follow during implementation of the TVM modernization initiative.
The technical specifications address three primary construction details: anchor bolt removal procedures, concrete trench and below-grade conduit installation, and conduit cap installation. For anchor removal, contractors must identify existing anchor types and core drill around anchors with sufficient size for complete removal, unless anchors can be removed without damaging surrounding concrete. Concrete replacement must meet 4200 PSI Class "P" specifications with light broom finish, and any cut reinforcing must be cold galvanized prior to replacement. Below-grade conduit work requires coordination with the Responsible Transportation Department (RTD) prior to concrete removal, and all voids must be filled with non-shrink grout. Conduit caps utilize Schedule 40 PVC materials with polyurethane sealant finish and non-shrink grout to seal edges, with specific dimensional requirements of 8 inches to 12 inches as detailed in the specifications.
