CSAH 14 Design-Build

SRF served as the lead designer on the first county-led design-build roadway project in Minnesota: the Anoka County CSAH 14 Design-Build. The $36 million project reconstructed three miles of CSAH 14 between TH 65 and Hanson Boulevard to convert the two-lane road into a four-lane divided urban roadway. As the lead designer on the C.S. McCrossan team, SRF’s design included a new bridge over the BNSF Railroad, five traffic signal replacements, several water quality ponds, and the realignment of a portion of County Ditch 60 near the Blaine High School. With an aggressive five-month design schedule and multiple construction stages, the project also required temporary traffic control measures and traffic detours, as well as utility coordination and relocation.

SRF’s innovative design resolved several challenges unique to design-build projects:

  • Quality: SRF fulfilled performance and warranty requirements by developing and applying a comprehensive Quality Management Plan (QMP) that addressed design, materials, construction, and information management.
  • Risk: The design-build delivery method places risk on the contractor design-build team. Throughout design and construction, the team managed potential risks to mitigate impacts to the project cost and schedule.
  • Traffic Control: SRF’s transportation management plan (TMP) minimized disruption along CSAH 14, an important arterial for Anoka County and the cities of Blaine and Coon Rapids. The TMP limited the durations of necessary road closures, accommodated nearby schools and businesses, and maintained the level of service along CSAH 14.
  • Poor Soils: The team performed extensive subsurface soil investigations during design to fully understand the limits of poor soils. Extensive utility coordination and innovative soil correction measures also accommodated an aggressive construction schedule.
