Abstract
Analysis of the causes of delay in construction projects has been a subject of extensive research in the past. The quantification of their corresponding effect on construction productivity and progress of the project has also seen research in the form of multiple case studies. However, concrete and simple ways whereby planners, contractors and other stakeholders in a construction process can use this research to predict overruns in a construction project have not been developed. In this paper, the authors have developed a simulation model that uses input from the user, knowledge of common construction delays and their effect on productivity to generate an estimate the deviation of a construction project from its theoretically calculated duration. The same has been demonstrated by application to case studies, and the results thereby discussed which are matching with the actual duration of the project.
