Design-Build History at MoDOT

MoDOT was granted authority to use the Design-Build process on three pilot projects by the Missouri General Assembly in 2004. One was to be in St. Louis; one in Kansas City and one could be elsewhere in the state. MoDOT embarked on its first DB procurement in 2005 with the $535 million reconstruction of Interstate 64 in St. Louis. In 2007, the second Design-Build procurement began for the $245 million I-29/I-35 kcICON Christopher S. Bond Bridge over the Missouri River. The third Design-Build procurement was launched for the Safe & Sound Bridge Improvement Program in 2008, replacing 554 bridges across the state for $487 million. All three projects received national acclaim and were completed on time or ahead of schedule and on or under budget.  Following that success, the Legislature granted further DB authority to MoDOT by allowing up to two percent of its annual number of projects to be delivered via the DB delivery model.  As of February 2019, MoDOT has embarked on 14 design-build projects with another procurement process, for the I-270 North project in St. Louis, on the horizon.
