The East and Gold Line Enterprise (EAGLE) P3 commuter rail project was part of the single largest RTD FasTracks program to expand rail and bus transit throughout the Denver area. This 40-mile, $2.1-billion project was opened to the public in 2016. The project included the construction of 39 bridges, 13 stations, hundreds of walls, and a large Commuter Rail Maintenance Facility (CRMF).

Construction Quality Assurance

Kleinfelder provided quality assurance field and laboratory testing, observations, and special inspections for all work items including earthwork, embankment, utilities, bridges, retaining walls, track, stations, maintenance facilities, communication systems, electrical systems, roadway, maintenance of traffic, and pavement items. Clear and complete quality documentation was critical to demonstrate compliance with project requirements. Kleinfelder developed electronic document control capturing plans and naming conventions, as well as unique project inspection checklists tailored to the project requirements. This innovative system helped to ensure that there was documented evidence that project requirements were completed and that the thousands of documents generated could be easily recalled as needed.

Environmental Compliance

As the environmental compliance manager, Kleinfelder was responsible for maintaining the compliance monitoring program and collecting proper inspection documentation. Additional environmental specialists identified environmental compliance issues, conducted required surveys and inspections, and delivered documentation based upon project permitting requirements. The environmental compliance team’s effective relationship with state and local jurisdictions, Regional Transportation District, and the contractor streamlined the permitting and compliance processes. Furthermore, Kleinfelder’s electronic data collection system provided environmental observation and inspection reports within 24 hours.

Kleinfelder’s environmental responsibilities included Phase II ESAs, including contaminated soils and groundwater compliance; stormwater and hazardous waste management; asbestos monitoring and abatement; noise management, landfill remediation; construction in wetland/waterbody features; raptor surveys; migratory bird surveys; threatened and endangered species; and National Environmental Policy Act (NEPA) compliance.

Project Results

Kleinfelder’s project team executed a diligent approach and provided attention to detail, helping the client successfully address program challenges with time- and cost-saving solutions. Kleinfelder developed the process to electronically capture and enter, trace, and retrieve CQA documentation, reducing document control costs by $500,000. The commuter rail line opened to the public in 2016.
