Building Schedule Risks Simulation by Using BIM with Monte Carlo Technique

Abstract

Risk management in construction projects has great importance through its impact on the basic objectives of the construction projects, as controlling the risks of the construction projects helps reduce cost overruns and time overruns and improve the quality of the construction projects. This paper aims to highlight the role of BIM in risk management in construction projects by generating a predictive risk model using Monte Carlo simulation to analyze a number of risks and generating a 3D model and 4D model to show the effect of risks. The predictive risk model can help project managers control the risks that affect the construction projects and enhance communication between all stakeholders for the project. The methodology was applied to two risk scenarios, the optimistic scenario for risks, and the pessimistic scenario for risks in one of the construction projects in Iraqi through the use of four commercial programs working together. The study concluded that the building information modeling technique has great importance in reducing the risks affecting the construction project by showing the effect of these risks during the project’s construction phases and controlling them.
