  • BIM approach resolved conflicts, saved time, and conserved energy
  • LEED Gold certification design to set standard for regional commuter rail improvements
  • Thoughtful and environmentally responsible building material fabrication and recycling.

Gannett Fleming provided project management, building information modeling (BIM), civil, architectural, industrial, structural, and industrial waste engineering services to complete a new commuter rail maintenance facility (CRMF) for the Denver Regional Transportation District (RTD) FasTracks Commuter Rail System. The CRMF project team also collaborated on energy and daylight modeling. Finished in Fall 2014, the CRMF is a vehicle repair, maintenance, cleaning, and storage location that will serve four FasTracks commuter lines: the Gold Line, East Rail Line, Northwest Rail Line, and North Metro Rail Line.

Part of the FasTracks’ Eagle P3 Project with 36 miles of new commuter rail lines in the works, the CRMF features six tracks with 36 vehicle spots and nearly 230,000 square feet of floor space spanning four levels. The system will use 25-kV overhead catenary, servicing trains consisting of two or four cars. An initial fleet of 54 electric multiple unit commuter cars will be serviced, inspected, and maintained at the CRMF that also includes a system operations and control center for the entire FasTracks Commuter Rail System located on the second floor. The CRMF initiative and larger Eagle P3 Project support RTD quality-of-life improvements.

What We Did

Gannett Fleming developed BIM and sustainability models to optimize CRMF collaboration, constructability, scheduling, and efficiency. Autodesk Revit 3-D BIM improved architectural; structural foundation and framing; and mechanical, electrical, and plumbing design discipline coordination throughout CRMF project development. To enable energy conservation, the project applied whole-building energy and daylight modeling during a design that reduces water consumption associated with plumbing fixtures and irrigation.

By creating and modeling the movement of equipment and materials around the site, Gannett Fleming’s CRMF BIM model also reduced team conflicts and delays. During construction, models were used to provide accurate and complete electronic construction information in the field. BIM facilitated submittals, staff coordination, and off-site material fabrication. Gannett Fleming documented sustainable design features related to LEED certification with the same 3-D model used for BIM. Designed to achieve LEED Gold certification, CRMF building materials were sourced regionally and contain recycled content whenever possible.

Key Features

  • Autodesk BIM software used for multidisciplinary coordination
  • Building information, energy, and daylight modeling
  • CRMF contains supervisory control for entire Denver FasTracks Commuter Rail System.

Sustainability Features & Outcomes

  • Carpool-designated parking spaces to save fuel costs and reduce air pollution
  • CRMF encourages safer and cleaner lifestyle by supporting public transportation
  • CRMF building materials were recycled
  • Dedicated commuter rail stop for CRMF workers supports efficiency
  • Holistic modeling approach promotes forward-thinking LEED certification design.
