Project Location: Denver, Colorado
Synopsis of work:
The last bridge deck for the 36-mile RTD Eagle P3 (Public-Private Partnership) commuter rail project was poured by Ames civil crews in September 2015, after nearly five years in the making. Ames was a joint venture partner using the P3 alternative delivery method for the design-build of the mass transit project, which is the first transit P3 of this magnitude in the United States.
The contract included construction of 36 miles of new double-track electric commuter rail lines, 14 miles of new freight rail track work, 32 bridges, 30 at-grade crossings, 14 stations with Park-n-Ride lots, and a major vehicle maintenance facility. The project scope included grading, concrete and structures work.
Testing on the train vehicles and integrated system of train control included at-grade intersections with gates, signals, automobile traffic signals, communications, and Active Train Control (ATC) and Positive Train Control (PTC).
The Eagle P3 is comprised of RTD's East Rail Line, Gold Line, Commuter Rail Maintenance Facility and Northwest Rail Line Westminster segment; the new commuter rail lines opened one at a time in sequence throughout 2016.
The project was awarded Star performance status from OSHA in its Voluntary Protection Program (VPP). Star companies have achieved injury and illness rates at or below the industry national average, and demonstrate an exemplary worksite with comprehensive, successful safety and health management systems.
