The current drilled shaft (also called bored pile) foundation design procedures recommended in two commonly used North American foundation engineering manuals have been reviewed, and the recommended design approache from each manual is evaluated against the recent load test data conducted on continuous flight auger (CFA), cast-in-place concrete piles (augercast piles). The soil conditions where pile load tests were carried out is typical of glacial till encountered in the Canadian Prairies. The conclusion is that pile capacity prediction methods widely used in North America generally under estimate both skin resistance and end bearing for drilled shaft in very stiff to hard glacial till. For design purpose, for drilled, cast in-place concrete piles installed in glacial till soils in Western Canada, procedure recommended by Federal Highway Administration (FHWA) is recommended.
