The installation of pile (drilled shaft) 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. This study is designed to assess these problems using regression technique. The piling process activities' duration, productivity, and cost 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. Seven regression linear models have been designed and validated to assess productivity, cycle time, and cost.
