Every Day Counts - Prefabricated Bridge Elements & Systems (EDC-PBES)
Usage Restrictions / Parameters
The FHWA has deployed a new initiative, entitled "Every Day Counts," which is intended to highlight some advantages of accelerated project delivery. Both the FHWA and FDOT support the use of accelerated project delivery techniques such as precast/prefabricated bridge elements and systems as an economical way to increase quality, reduce costs and construction time, and support safety. Use of these innovative concepts aids in solving many constructability challenges, while potentially revolutionizing bridge construction in the United States.
Prefabricated bridge elements have been in use for many years when the
situation demanded specialized details and construction methods due to
unique site limitations. This same approach can be used to minimize
the impact to the travelling public by reducing construction time.
Investigating the use of prefabricated elements versus conventional
construction helps determine the best balance between direct and indirect
costs while delivering the bridge project in a timely manner and minimizing
impact to the traveling public.
The Structures Design Office has created an EDC-PBES website with designer tools such as:
Visit the website at:
FDOT PPM Volume 1 Section 188.8.131.52 â€“ Currently requires designers to:
Investigate the use of either partial or full precast bridge alternate(s) with the specific purpose of accelerating bridge construction and reducing user impacts.
Valid on all Design-Bid-Build projects per Structures Design Bulletin 12-07. Use on Design Build projects is highly encouraged and subject to project scope demands.
These topics are discussed within the case studies presented on the EDC-PBES website.
