Abstract: This research aims to address the absence of a suitable multiple regression model for predicting skirting lengths in buildings, which leads to cost overruns, inaccuracies in estimates, and project cancellations. The study focuses on developing a regression-based model specifically tailored for predicting skirting lengths in Anambra State. The research objectives include identifying factors influencing skirting estimate accuracy, assessing the impact of skirting estimates on overall project estimates, and proposing a predictive model based on floor area and length of door openings.
