How to Determine Construction Project Rain Delay Times Using Local Rainfall Databases in Asheville, NC

Rain delays can prove costly to construction contractors and significantly affect long-term profitability if not carefully considered during the planning stages of a project. This paper includes a short literature review of technology related to predicting construction project rain delays and an analysis of rainfall event probabilities for the Asheville, North Carolina region. An analysis methodology is provided in a step-by-step discussion which illustrates how to determine statistical probabilities of significant rainfall events to forecast construction project delays. Local rainfall data for Asheville, NC is analyzed to determine rainfall frequency to provide an example of the forecasting methodology for the reader.
