A dynamic model of the effects of project complexity on time to complete construction projects

Abstract

The aim of this paper if to investigate the factors driving project complexity in construction projects and how they impact on project cycle time. This issue has been addressed by building a framework for project complexity for construction projects and evaluating is impact on project cycle time through a System Dynamics (SD) simulation model integrating project complexity, project operations, and its time performance. The results indicate that project complexity is driven by four factors: Project Uncertainty, Infrastructure Newness, Infrastructure Interconnectivity, and Infrastructure Size and that Project Uncertainty is the most influential factor on project cycle time comparatively to the other factors.
