Abstract:

Accurate cost estimates for water supply system expansions are an important component of the planning process. A spreadsheet-based cost estimating model called SWFCOST was developed as part of the water supply planning effort of the Southwest Florida Water Management District (SWFWMD). SWFCOST was designed to permit the user to evaluate and adjust the underlying assumptions used in the costing procedure. Using the output from SWFCOST, a methodology was developed to enable the user to compare the model results with other sources of cost information. A weighted least squares curve fitting procedure is combined with user-controlled techniques in order to obtain the 'best' cost estimate on a case by case basis. The result of this analysis is a decision support system (DSS) that permits the user to evaluate the model and a supporting database in any level of detail. Example applications are included.
