Installation of augered cast-in-place (ACIP) piles, which are uncased as the auger is removed and the pile is grouted, will always be accompanied by ground displacements. Managing the installation to minimize ground displacements can be of special importance in urban areas where nearby structures or buried utilities might be affected adversely. Experience with ACIP installations in New York City and southern Florida has led to the development of recommended procedures to reduce soil loss during installation and the associated ground displacements. Rationales for recommended rates of auger insertion, auger rotation during grouting, grout pressures, and pile spacing are provided. Observations confirm that soil loss during installation is less when ACIP piles are installed in cohesive soils instead of other materials. To help engineers to manage the installation of ACIP piles, information is provided in some detail.
