Over 50% of Korean government construction projects were reported to have been delayed over two years by frequent design changes. These problems are originated from the dynamic and uncertain characteristics of construction projects, such as unpredictable design changes. In particular, civil engineering facilities such as large-scale cable-stayed bridges are complex and require a thorough construction planning, because construction managers often find it difficult to have the construction processes under full control. For the purpose of comprehensive construction planning, virtual 3D process modelling can be utilized. Through the virtual process modelling, construction managers can forecast critical issues of the construction phase and prepare solutions for potential problems. In this research, a cable-stayed bridge construction is analyzed and modelled using the 3D graphic and simulation approach. This effort is expected to improve the construction processes and identify the limitations and capabilities of the 3D process modelling in bridge construction projects.
