Based on current design practice, the base resistance of a pile often ignored which results to inadequate pile load design. Besides mobilising factor, the ignorance of base resistance may be due to uncertainties in effective cleaning of the boreholes. This paper represents determination of base capacity for bored pile towards hard stratum. Empirical equations and reviews related to ultimate base resistance from Standard Penetration Test (SPT) data results obtained from site investigation (SI). Results from several analysis have been evaluated by taking account of overburden pressure in the order to prove the existence of base capacity for bored pile at site. Aspect of construction for bored pile in hard stratum also presented together as it related to important matters towards base capacity and performance of the bored pile itself. Based on the result obtained, method by Meyerhof (1976) gives the best prediction of base capacity for hard stratum in Malaysia as the existance of base capacity itself cannot be ignored to get an adequate bore pile load design.
