This paper focuses on developing a predictive model for determining settlement-time response of pile load tests from the coastal region of Nigeria. Non-parametric statistical analysis was carried out on the load-settlement response data of static load test of piles from five locations in Lagos metropolis, Nigeria. Regression analysis was done on the predictive settlement data to determine the required predictive model. The maximum settlement observed was 9.991 mm with a mean value of 7.892 mm. A significant correlation of more than 50 % existed for the various settlement data. Consequently, a predictive model was developed for determining settlementtime response of static pile load tests.
