Route 6/10
Reconstruction Project

Providence, RI

CME assisted RIDOT with the procurement of the largest single Design-Build project in RIDOT history. CME was charged with development of the base technical concept design and all procurement documents for this major interchange replacement project located in Providence, RI. Challenges for this project included handling of heavy traffic volume in a tight corridor to allow for the replacement of numerous structures in this stretch of highway. CME 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.

CME is continuing engineering support during construction by reviewing plans, attendance at design meetings, and troubleshooting engineering issues including providing an innovative solution for beam end corrosion discovered during construction. CME provided the detailing for more than 25 beam end repairs using Ultra High-Performance Concrete.

The 6/10 Interchange serves as a major interchange in the heart of Providence. This interchange also includes connections to three major neighborhoods in Providence. The goals for the project including re-build the interchange to current standards, improving the operational efficiency, and improving neighborhood connectivity and pedestrian/bicycle access through the impacted communities.

This project is being constructed using Design-Build contracting. While the Department had a Design-Build Program in place, there were areas where they wanted to improve their program for larger projects. CME and RIDOT reworked their existing policies and solicitation document templates to deliver projects more effectively and to work on a wider scale.

CME developed the base technical concept (BTC) for this important section of highway and developed the construction staging plans to handle traffic volumes and ensure smooth transitions throughout construction. The BTC included replacing several severely deficient bridges, six of which cross the electrified AMTRAK Northeast Corridor and creation of a flyover bridge ramp to provide the missing US 10 northbound to US 6 westbound connection.

CME’s project solutions have been innovative in several ways. During construction, a need arose for emergency repairs to corroded beam ends on several of the existing bridge structures. CME approached RIDOT with a new repair method for steel beam ends that was being studied by University of Connecticut for the Connecticut DOT, based on an idea proposed by CME. The research, which uses Ultra High-Performance Concrete, has the potential to save time and money for these repairs. CME designed the repairs for more than 25 beam ends, which were successfully completed using this method. RIDOT is now considering using the repair at other bridge locations.

We also introduced an electronic, cloud-based review program that allows multiple parties to collaborate on design reviews, consolidating comments and reducing the timeframe to reconcile comments. This was critical to maintaining the schedule for this aggressive project that is considered a high-priority project by the State.
