Kansas Partnership Selects Design-Build Team for Turner Diagonal Project

Updated: Nov 8, 2019

Economic development and transportation mobility surrounding the Interstate 70 (I-70) and Turner Diagonal interchange will soon be enhanced as the Unified Government of Wyandotte County and Kansas City, Kansas (UG), the Kansas Turnpike Authority (KTA), and Kansas Department of Transportation (KDOT) have selected Clarkson Construction Company to complete the final design and construction of the interchange.

Clarkson Construction Company is a leader in delivering innovative solutions to some of the biggest infrastructure projects in the Midwest. Now in its sixth generation, family-owned Clarkson continues to set the standard using 21st Century technology to connect our communities and move them closer to the future. Selection of the design-build team was based on how well they satisfied requirements set forth in the request for proposals. Teams were evaluated based on their ability to demonstrate how they would complete the new interchange on or before October 16, 2020, deliver within budget, minimize impacts to traffic and minimize maintenance.

Clarkson Construction Company received the highest score of the three teams that submitted proposals. “The selection team reviewed three fantastic proposals which made our decision difficult,” said KTA Project Director Rex Fleming.

“We feel confident that Clarkson Construction Company can deliver the project within the time and budget required. By using design-build delivery, it allows the team to expedite the construction schedule so that the interchange can open to traffic before the fourth quarter of 2020.”

Design-build streamlines project delivery through a single contract between the owner (KTA) and the design-build team. Combining the skills of designers and contractors at the project’s onset allows for positive collaboration, which can result in faster project delivery, more efficient use of materials, and lower labor costs.

The Turner Diagonal Project will reduce the existing interchange footprint and create a new diverging diamond interchange (DDI), thus opening up the previously used land from the interchange for development. Improvements to the truck staging area immediately west of 72nd Street as well as a new dedicated pedestrian pathway will also be included in the improvements. The total project cost is $30 million. $13.8 million of the project cost will come from a U.S. DOT BUILD Grant that the UG received in 2018. The remaining costs will be covered by a combination of UG, KDOT, and Northpoint Development funding. Collaboration between all four groups is an efficient and cost-effective approach that will make this project successful and be a model for doing business in the future.

The partner group will spend the next few weeks getting contractual agreements in place. “We anticipate that construction will begin in early 2020,” said Reno. “After the contract phase is completed, the project team will begin final design. We will send out information to the public as soon as design and construction dates become firmer in the weeks to come.”
