This paper deals with the reanalysis of the foundation of an already existing Vaccum Distillation Unit in an oil refinery. The reanalysis is required to suggest if the existing foundation of the unit would be capable enough to withstand an additional pressure intensity to which it would be subjected due to proposed expansion of the unit. The paper therefore discusses the geotechnical investigation program undertaken for evaluating the relevant design parameters and the methodology adopted to compute the sustainable pressure of the foundation
