This document is an update to Deep Foundations Institute (DFI) Augered Cast?in?Place (ACIP) Pile Committee's ACIP Pile Manual (Model Specification) (2003 version). The Guideline Specification and Commentary content have been updated to address current trends in ACIP Pile installation and quality control, the use of increased ACIP pile diameters and lengths to provide significantly higher load carrying capacities, and the challenges associated with the use of grout and reinforcement necessary to sustain such higher loading. The order of the Guideline Specification has been revised to more closely match the format typically utilized in project specifications. This document is intended to provide the industry with practical guidance in the preparation of a project?specific specification.
