Challenge Design-Build Project Delivery Addressed

Sean Matlock, PE, MoDOT Project Manager stated, “In design-build, all work is incorporated into one contract and decreases the project delivery time, while allowing the design team to incorporate innovations and efficiencies into the project. This gives more flexibility and allows changes within the project design as challenges arise. It was expected with design-build that teams would deliver innovative interchange designs at Route B/VV, providing access to adjacent properties, maintaining traffic during construction, delivering the needed right-of-way acquisition plans on a tight schedule, keeping project costs under control and delivering a successful project to the community.”

Summary

Rogersville Project Freeway in Missouri consisted of converting four miles of US 60 into an access-controlled freeway to facilitate safe and efficient traffic movement. MoDOT used a unique procurement strategy that allowed maximum innovation. The Ozark Regional Road Constructors team rose to the challenge by devising two unique grade separated interchange concepts, which enhanced traffic operations, improved safety and significantly reduced right-of-way acquisition costs, which was a major selection criteria established by MoDOT during procurement.
