Accelerated Bridge Construction – Small Bridge Replacement Strategies
(1 Day Hybrid Online Class)
October 12, 2021
7:45am EST – 4:00pm EST

Accelerated bridge construction incorporates several fundamental attributes that reduce road user impacts, costs and construction time.  Incorporation of ABC practices into your project will help minimize traffic delays and community disruption while increasing safety in the construction zone.  The instructor uses Accelerated Bridge Construction to introduce several strategies that state and local agencies utilize to replace small bridges.

Join instructor, Walt Catlett for this lively online class and discussion forum that will change the way you think about small bridge replacement options.  You will learn more about accelerated bridge construction fundamentals, bridge terminology, precast concrete box culverts, three-sided rigid frames, precast modular bridges and geosynthetic reinforced soil integrated bridge systems.  By the end of the training, you will learn the basic steps for manufacturing, delivery and installation of these ABC options while challenging your perceptions on current practices.

Who Should Attend: This class was developed for inspectors, installers and design engineers alike.  Previous experience with small bridge replacement design, installation or inspection is not required.  Inspectors, installers, engineers, planners, equipment operators, and laborers will learn accelerated bridge construction concepts, basic bridge concepts, and techniques critical to the successful installation and inspection of precast bridges elements/systems.
