4D BIM for improving plant turnaround maintenance planning and execution: a case study

Four-dimensional (4D) Building Information Modelling (BIM) has been credited with improving construction planning procedures. The integration of 3D model with schedule information has enabled the effective detection of design and planning flaws in many construction projects. Due to the lack of research on using 4D BIM in Turnaround Maintenance (TAM) projects, this paper firstly introduces a novel framework of applying 4D BIM to improve TAM process planning and execution. Then, a real TAM project was selected to validate the effectiveness and efficiency of the proposed framework. Finally, benefits such as time and cost reduction, and safety improvement are calculated and explained.
