Drilled foundations often are socketed into rock to increase the capacity. However, procedures to quantify the socket side and tip resistance vary considerably. This paper reviews methods to predict socket capacity and critically assesses them. One method for side resistance is recommended, and several approaches are suggested to assess tip resistance, depending on the degree of geologic data available. Statistics for the methods are given, where available, and design and construction implications are noted.
