LCA Research Brief: Initial Cost Uncertainty in LCA

May 1, 2013

Using historical bid data to characterize uncertainty in initial costs for LCCAs will help improve the accuracy of probabilistic LCCAs. Some of the cost variation can be explained by understanding the implication of bid quantity, but the amount of variation that can be explained can vary significantly from state to state for similar bid items. Future work will explore including other factors that could impact initial costs. MORE
