A multivariate delay estimation model proposal for public construction projects

Abstract

One of the most common problems in construction projects is delay. Delays lead to loss of time and an increase in cost, which causes great damage to firms and the economies of countries. In previous studies, many researchers have attempted to identify the factors causing the delay by carrying out questionnaire surveys and interviews. However, there are very few studies that have compared the data obtained by these models with actual project data and suggested an estimation model that can determine the possible delay time for future projects. This study aimed to propose precisely such a model for public construction projects based on multivariate analysis. Obtained results show that the set-up non-linear model with selected attributes had satisfactory prediction results.
