Abstract : The MAPS (Methodology for Areawide Planning Studies) computer program is often used to develop planning level cost estimates for a large array of water resources facilities including dams, pipes, pumping stations, open channels, storage tanks, tunnels, water treatment plants, and wellfields. While the MAPS cost estimates have often been checked against actual facility costs, this study was conducted to systematically verify the MAPS cost functions against a set of actual costs of projects. Data were provided for the study by a large engineering consulting firm. The study showed that while some minor modifications to the program were required, the MAPS estimates were of sufficient accuracy for planning studies. For the 35 facilities considered, the geometric mean of the percent differences between MAPS estimates and actual costs was 13.9 percent. (Author)
