Construction Project Scheduling Risk Analysis Using Event Chain Methodology: An Example of Airport Terminal Project

This paper describes a new perspective to consider and quantify uncertainty in construction schedules. In the study, a methodology was presented by modeling construction project scheduling using event chains, classification of the events and event chains, identification of critical events, analysis of effect of the events on project duration, and chance of project completion. To demonstrate the applicability and effectiveness of the proposed methodology, a real airport terminal example is provided. Moreover, schedule risk analysis system and risk break down structure are also developed as an essential part.
