I-395/SR 836/I-95 Expansion Joint Installation

In addition to the expansion joint installation, Freyssinet’s scope of work entailed designing, furnishing, and installing CFRP (Carbon Fiber Reinforced Polymer) fabric strengthening to five different piers on the SR 836 bridge structure. The total concrete area prepared for CFRP strengthening was 293 FT². The process involved sandblasting the concrete at the designated areas, installing Freyssinet’s specially designed CFRP (FOREVA® TFC-1100) according to the design, allowing it to cure properly, and applying a protective coating.

To access two of the piers, man lifts were utilized, which required the client to provide traffic control. The other piers were easily accessible from under the bridge by working off fixed platforms. Freyssinet performed the work on the bridge structure quickly and efficiently. The CFRP on the five piers was applied within a 3.5-day span, and the coating was completed within two days. Freyssinet sent their workforce from Southern Virginia. Freyssinet established a good relationship with the Project Superintendent, a key success factor, as the equipment and necessary traffic control were adequately available and in-place whenever they needed to perform the work.

Freyssinet achieved a successful project thus far due to close collaboration with the Design Build Contractor, multiple Design Build Engineers, FDOT, and FDOT representatives.

Freyssinet proprietary expansion joints were proposed by the Design Build Team as an alternative to the system identified in the initial design documents. Freyssinet joints were well received and recognized for their excellent performance, durability, and overall economy.
