Augered Cast-in-Place (ACIP) piles are prevalent in vertical structures while bridge and transportation structures have been slow to adopt, with AASHTO not addressing their design. The Ohio DOT used 176 ACIP piles in a 217’ long pier footing requiring battered, reduced & low headroom, and phased installations within a highly charged aquifer. This is an overview of the project, geotechnical design, structural design, installation process, testing, and lessons learned from this first-of-its kind foundation for Ohio DOT.Â
