The installation of pile foundations is complicated by an enormous number of problems. They include unseen subsurface obstacles, lack of contractor experience, and site planning. These major problems and other minor ones make it difficult for the estimator to evaluate the piling project productivity and cost. Therefore, this study is designed to assess these problems using simulation. Both piling process productivity and cycle time assessment are addressed. Data were collected for this study through designed questionnaires, site interviews, and telephone calls to experts in different construction companies. Many variables have been considered in the piling construction process. Two simulation models have been designed and validated to assess piling process productivity and cycle time. Consequently, two sets of charts have been developed based upon the validated models to provide the decision maker with a solid planning, scheduling and control tool for piling projects.
