A study was carried out generally to obtain the reliable range for Ultimate Skin Factor,Ksu and Ultimate End Bearing Factor, Kbu with the change in Standard Penetration Test (SPT, N) value established for the soil in Malaysia. Pile instrumentation is to be done using state-of-the-art Global Strain Extensometer technology consists of a deformation monitoring system that uses advanced pneumatically anchored extensometers coupled with high-precision spring-loaded transducers, and a novel analytical technique to monitor loads and displacements down the shaft and at the toe of foundation piles. The results from Global Strain Extensometer show that the skin resistance factor (Ksu) is in the range of 2.0 and 2.3kN/m2 as found by Pienwej et. al (1994) and Tan et. al (1998)). The results for base resistance factor (Kbu) for Global Strain Extensometer also in the range of 7.0 to 10kN/m2 of value found by Tan et. al (1998).
