Effects of Construction Installation Methods on the Design and Performance of Drilled Shaft Foundations

The main objectives of the research program are to quantify the installation effects on side and end resistances for different types of drilled shaft foundations (e.g., uncased, cast in drilled hole [CIDH], and cast in steel shell [CISS]) in different soil conditions due to various installation methods (e.g., dry method vs. wet method; natural vs. synthetic vs. blend drilling support fluids; temporary vs. permanent steel casing; driven vs. drilled vs. spun into the ground; rotary drilling methods vs. vibratory/impact hammer vs. grab methods; etc.). Ultimately, a report will be developed that will present how the various construction techniques affect design, which will form the basis for design guidance for state DOTs regarding technique-dependent installation effects.
