Case Study
CDOT: Region 2 Bridge Bundle Design-Build Project, 23558
Using an FHWA grant CDOT executed a Best Value based Design-Build delivery to replace 17 rural bridges expeditiously and economically in Colorado. The Best Value scoring model emphasized scope, price, delivery time and public convenience and included a robust ATC process. Through strong collaboration, six approved ATCs and innovative designs, the Capital-Tezak team (a Capital-led joint-venture with Tezak Heavy Equipment based in Canon City, CO with Wilson & Company as the Engineer of Record) provided the lowest price, and shortest delivery time, while minimizing public inconvenience.
Our Approach
A high degree of collaboration was maintained throughout the project, supporting the design and construction of multiple structures concurrently, including revised designs to better align with existing site conditions and constraints, and reduce project costs. As a result, the project realized tangible savings; Original Proposal Upset Amount was $43.4M, after mutually agreed Deductive COs, the final contract value was $42.3M, with completion 22 weeks ahead of schedule. The innovative designs will prove beneficial for future rural bridge projects.
Results
Capital was able to minimize the impacts to the residents with a public involvement program. This program includes social media outreach, community meetings, and press releases.
This Design-Build project demonstrates how prioritizing building relationships, customer satisfaction, and safe, quality work can produce innovative solutions and exceed delivery expectations.
