Abstract: In the construction industry, cost estimates are the basis for which projects are awarded to suppliers. A cost estimate is arguably the most important inclusion in a supplier's response to a customer's 'request for quote'. As such, it is essential for construction cost estimates to include features of accuracy, cost effectiveness and profitability for the supplier. The amount of variables and qualitative considerations in an estimate require a methodology beyond an objective approach. This paper uses data analytics to analyse both a US Government service provider's internal estimate process and suppliers' external estimate process to determine the best approach to use on future task orders. Three different classifier methods were used to perform the data analytic approach. Based on analyses performed for all three methods, RBF-based support vector machine with a 66%-33% random split and ten-fold cross-validation yielded the highest accuracy at 71%.
