State Road 64 Project
The very first Box Culvert project was a severely compromised structure that was an estimated 9o plus years old, located in the middle of downtown Bradenton, Florida. Two factors existed that are common when facing replacement of sub-surface infrastructure, which forced the Florida Department of Transportation to explore a workable rehab solution.
- Diversion of traffic was not an option, along with the fact that City of Bradenton and Manatee County officials were strongly opposed to any procedure that required open cut of SR 64. After all, State Road 64 was One-Way through downtown and served as the lone feeder route to Anna Maria Island on the Florida West Coast.
- The funding required to go with excavation and replacement was well beyond the District One annual budget, however our Cast-In-Place solution easily fell under FDOT emergency maintenance guidelines, allowing for a project change order approval.
JW & Associates USA was invited during August 2011 to evaluate this challenging project to seek a rehabilitation solution. Our recommendations were presented to a project review board, comprised of engineers from FDOT, the Senior Project Manager for the primary contractor performing the SR 64 Design/Build project and the Engineers of Record, overseeing the Design Build. Once the board was in agreement that our proposed solution offered true structural renewal as a stand-alone structure and our Cast-In-Place construction procedure could be performed without disruption to traffic, JW & Associates USA was commissioned to prepare and submit a written construction procedure.
After presenting our written procedure in detail, FDOT came back with just two stipulations for Release for Construction.
- Provide complete engineering plans with calculations that would validate H-20 load capability as a stand-alone structure.
- JW & Associates would write a Technical Special Provision, bearing the signature and raised seal of a licensed State of Florida Engineer.
The SR 64 engineers of record stated that our box culvert procedure was performed well inside the contract deadlines. Following completion the primary contractor informed us that we saved the FDOT more than a half a million dollars on an estimated $720,000 storm water structure replacement. The exciting part of the role we played was developing a design plan that met all the engineering demands and gaining FDOT approval. This project remains today as the only known structure of its kind in existence. Not for Long!
