US 285 Reconstruction Design-Build

Denver, Colorado

Tsiouvaras Simmons Holderness teamed with Concrete Express Inc. to provide complete design–build services for the reconstruction of 4.7 miles of US 285 including the replacement of six bridges, rehabilitation of seven bridges, and reconstruction of both asphalt and concrete roadway between Kipling Street and Federal Boulevard. The roadway work included both reconstruction for alignment shifts to accommodate new structures and filling in the median while maximizing the limits of the overlay on the existing pavement structure. Extensive traffic control with refined detours were utilized to reduce the traffic impacts along this well-traveled roadway. TSH provided construction services that included a complete construction quality assurance program with construction observation and oversight management of materials testing. Our staff worked closely with the contractor to develop a Quality Management Plan implementing both QC and QA to meet the contract requirements for delivery of this $40 million facility in accordance with the FHWA federal funding requirements.

  • Developed a project-specific Quality Management Plan to ensure delivery of all documentation meeting the FHWA guidelines for federally-funded projects
  • Provided a Project Engineer with three inspectors and two material testers to oversee all work in accordance with the QMP
