Five auger cast-in-place piles (ACIP) were installed at the National Geotechnical Experimentation Site located at the University of Houston campus in Houston, Texas in December 1996. Lateral load tests were performed on four of the piles in January 1997. The purpose of these tests was to evaluate the feasibility for design and construction of ACIP piles to support concrete screen walls subjected to large wind forces along highways in urban areas.
