ABC in Florida – A Practical Look into Past, Present, and Future FDOT Projects Utilizing ABC Techniques

6/5/2019 - 10:00am-10:50am

Over the past several years, the FDOT has developed an array of resources and expanded its policies in an effort to support the “Every Day Counts” initiative from the FHWA. Several policies, details, and decision-making tools, focused on the state’s specific bridge trends and work mixes, have been developed to assist designers and contractors evaluate the feasibility of ABC techniques for FDOT projects. FDOT supports the use of ABC and the implementation of prefabricated bridge element systems (PBES) for bridge construction as a means to reduce costs, user impacts, and construction time, however issues related to long-term durability and quality can be problematic depending on the details incorporated into the design. The focus of this presentation will include a brief synopsis of FDOT policies centered around ABC applications, as well as coverage of past, present, and future projects utilizing PBES components. PBES component and connection details, as well as lessons learned, from major projects including the Edison Bridge, I-10 over Escambia Bay Bridge, Veterans Memorial Bridge and the Pensacola Bay Bridge will be discussed. The presentation will also discuss the status of the agency’s upcoming Jupiter Federal bascule bridge replacement to be constructed utilizing ABC methods. The presentation will conclude with a discussion on where the FDOT is going next with ABC given infrastructure challenges associated with a growth state. Discussions will be made related to viaduct construction in the median of interstates, the next generation of structure types, and the benefits of specialized equipment and top-down construction methods.
