ABSTRACT: High-capacity continuous flight auger (CFA) piles have been successfully applied to support building foundations in Southern Ontario. The paper reviews the design methods for CFA piles and summarizes results of pile load tests published in the literature. Two compressive load tests conducted in Markham are presented. The ultimate resistance of CFA piles estimated from semi-empirical analysis are compared with that measured from the pile load tests. Methods used to estimate the factored resistances of CFA piles at the ultimate limit states (ULS) and serviceability limit states (SLS) are recommended.
