Design-Build Information

Download the MoDOT Design-Build flyer by clicking here.


As per Sec. 227.107, RSMo, MoDOT was given the authority for three pilot projects using the design-build project delivery technique: The New I-64, kcICON and the Safe & Sound Bridge Improvement Program. Each was completed ahead of schedule and on, or under, budget.

Subsequently, the statute was amended to give MoDOT the opportunity to enter into design-build contracts on no more than two percent of the total number of all state highway system projects awarded to contracts for construction from projects listed in the commission’s approved statewide transportation improvement project for that state fiscal year.

Design-build is a delivery method that includes hiring one contracting team to complete the design work and build the highway improvement under one contract. MoDOT provides the project goals, budget and schedule and the contractor team completes the work. This technique has been known to significantly save time and provide cost savings.

Design-Build Projects in Procurement


February 21, 2020 - For immediate release


Design-Build Teams Selected to Compete for Bootheel Bridge Bundle Project

SIKESTON - The Missouri Department of Transportation has received Statements of Qualification from potential design-build teams for the Bootheel Bridge Bundle project, which will repair or replace 15 bridges on the Southeast District’s asset management plan.

The SOQs have been evaluated and four teams have been prequalified to proceed.

“We are excited about the interest we have received in the project. Four teams have been selected to compete for the contract to oversee the design and construction of this bridge bundle project,” said MoDOT Project Director Jessie Philpot.

The following teams were selected to further develop their proposals on the project:

  • Kiewit - Benesch
  • Lehman - Wilson
  • Robertson Contractors, Inc.
  • Kozeny – Wagner, Inc.

Design-build projects combine both the design and construction phases into one contract. The selected contract team completes the design and construction in parallel instead of in succession, which saves time and resources.

Thirteen bridges in the Bootheel Bridge Bundle are included in Gov. Mike Parson’s $351 million Focus on Bridges program, which will repair or replace 250 bridges across the state and was authorized by the Missouri General Assembly in the 2019 legislative session.

MoDOT will issue the Request for Proposal this March. The design-build team is expected to be selected in July 2020, with construction beginning as early as summer 2020.


Thank you to everyone who expressed interest and put in the time and effort to deliver a SOQ for consideration,” Philpot added.

Request for Design-Build Services Letters of Interest for the U.S. Route 169 Bridge over the Missouri River

The Missouri Department of Transportation (MoDOT) is soliciting Letters of Interest from companies interested in providing design-build services for the John Jordan “Buck” O’Neil Memorial Bridge(formerly the Broadway Bridge), that carries U.S. Route 169 over the Missouri River and connects downtown Kansas City with communities north of the river in Jackson and Platte Counties.

MoDOT intends to replace the 100-year-old existing Buck O’Neil Bridge and make improvements to the U.S. Route 169 corridor. The anticipated improvements include replacing the existing Missouri River bridge, improving traffic operations, geometrics, and safety and bike/pedestrian/transit accessibility along U.S. Route 169, including direct connections from I-35 to U.S. Route 169. One design-build team will be selected to design and construct the project. In addition to design and construction, other project elements such as right-of-way acquisition, quality management and environmental management may be included as part of the design-build contract.

A virtual information presentation is scheduled at 10 a.m., Tuesday, July 21, 2020. A link to the meeting will be available on the project website,  It is anticipated the Request for Qualifications will be released on the same day as the presentation.
