I-395/sr 836/i-95 design build project (signature bridge)

The I-395/SR 836/I-95 Project is a collaboration between the Florida Department of Transportation (FDOT) and the Greater Miami Expressway Agency (GMX). The construction work is limited to State Road (SR) 836, starting from NW 17 Avenue, continuing through the SR 836/I-395/I-95 (Midtown) Interchange, and ending at the MacArthur Causeway Bridge. The work on I-95 spans from NW 8 Street to NW 29 Street. The project is expected to be completed in late 2027 at a cost of $840 million.

The Signature Bridge is the main focus of the project. It will transform the city’s skyline and become an iconic symbol for Miami and South Florida. The Signature Bridge and the adjoining structures will create vibrant community spaces underneath, linked together by a contiguous trail for the enjoyment of Overtown residents, nearby communities, and visitors.

UES partnered with the Archer Western – de Moya Joint Venture team for the design-build. For the design portion of the project, UES performed the geotechnical exploration, testing, engineering analysis, and recommendations, which included 19 bridges for segment 836, 20 bridges for segment 395, 2 bridges for segment 95, retaining walls, miscellaneous structures, roadways, and ponds. Some bridges were designed using driven concrete piles, while others used augered cast-in-place (ACIP) piles.

The utilization of ACIP piles in bridges is a new development in the field of FDOT construction. UES, in collaboration with FDOT, played a significant role in making this idea a reality by contributing to the design and construction of the first-ever FDOT bridge of this magniyude that uses ACIP piles. This project marks a milestone in the history of FDOT and sets a new standard in the construction industry.

For the construction portion of the project, UES’s scope included supplying the management scope for contractor quality control and pile testing, which provides engineering, clerical, and quality control manager services. These services include maintaining the quality control plan, job guide schedule, contractor density log book, and MAC test reporting. The pile driving inspector includes Construction Training Qualification Program (CTQP) certified technicians for inspections and monitoring of all test piles and production piles.
