• Abstract:
  The 2D Quick Check Statewide Initiative created a process where the Colorado Department of Transportation (CDOT) design projects are value engineered to improve safety, enhance efficiency, and reduce material costs early in the project delivery workflow. CDOT partnered with six consultants to develop 46 2D “Quick Check” (2dQC) models in 2021. Over the 46 2dQCs, $22.4 million in construction cost savings and resiliency benefits was identified. Another 108 design and safety innovations were discovered and documented. The success of the 2dQC initiative initiated a Phase 2 and Phase 3, so by 2024 there is a 2dQC program in place to reduce total project costs and streamline project delivery statewide. Implementation (Optional) The implantation of 2D Quick Checks involves (1) identifying a project-specific need or challenge, (2) collecting background information, (3) building a 2dQC model, and (4) sharing out results and alternatives to guide project decisions. Best practices, resources, and lessons learned were captured through the research initiative to help with these steps and are discussed in the body of the report. Through the initiative, a training curriculum was also developed to train internal and external partners on the 2dQC process and give others the knowledge and resources to implement 2dQCs statewide. The training course will continue to be offered through the next phases to ensure the success of this program continues and evolves over time.
