Computerized conceptual-cost-estimating system for domestic water supply projects

Abstract

This thesis presents a structured and systematic procedure for the implementation of a Computerized Conceptual Cost Estimating System (CCES) for Domestic Water Supply Projects. CCES has been designed to produce cost estimates at the conceptual stage when only a little information is available about the project. The research began with the identification of the factors influencing the costs of pipeline, reservoir, and pumping station projects. Next, historical cost data of commissioned projects were gathered from tender documents and subsequent regression analysis was carried out. The regression analysis was computer-based which facilitated a "what-if" analysis during the model creation course and helped examine the adequacy of the cost factors. The adequacies of the cost models were checked and found to comply with the standards of the American Society of Cost Engineers. The cost models were integrated into a user-friendly application software. (Abstract shortened by UMI.)
