Rhode Island Department of Transportation (RIDOT) – Providence, Rhode Island
Our team assisted RIDOT with the procurement of the largest single design-build project in RIDOT history. We were charged with development of the base technical concept design and all procurement documents for this major interchange replacement project located in Providence, RI. A Significant challenge for this project included managing heavy traffic volume in a tight corridor during the replacement of numerous structures. We developed preliminary highway and bridge layouts as well as traffic staging plans and ancillary engineering documents. The procurement was completed in less than 12 months and under budget.
Our team continues providing engineering support during construction by reviewing plans, attending design meetings, and troubleshooting engineering issues including providing an innovative solution for beam end corrosion discovered during construction. We provided the detailing for more than 25 beam end repairs using Ultra High-Performance Concrete.
Construction of the project is estimated at $248 million. Construction will be completed by 2023.
