Assessment of Pay Item Specific Case–Based Reasoning Approach for Bridge Unit Cost Estimation

Abstract

AbstractA pay item specific case–based reasoning (PCBR) approach was developed and assessed for estimation of bridge repair and replacement unit costs. Rather than predict overall project or unit cost as with typical case-based reasoning (CBR) methods, ...Practical ApplicationsThe case-based reasoning (CBR) method has been shown to be an effective way to improve the accuracy of cost estimates. CBR is based on the idea of using the costs of previous, similar projects to estimate the cost of a future ...
