Development of risk-based BIM integrated material resource control procedures to improve time performance on public facility construction projects in the Seribu Islands

This study aims to develop a material resource control procedure from a contractor's perspective that is integrated with 4D and 5D Building Information Modeling (BIM) technology, based on dominant risks at each stage, to improve project time performance. The research approach includes the identification and analysis of dominant risks, integration of activities with BIM, and data processing using the Delphi method and statistical analysis with SPSS version 27. The results of the study showed seven improvements to existing activities and the addition of nine new activities at the stages of shipping, receiving, storing, distributing, and using materials. Of all these activities, twelve can be integrated with BIM technology according to the results of risk validation. To ensure the feasibility of implementation, the developed procedure was tested through a case study on the Public Facility Construction (PFU) project in Gusung Klanceng. The results of the case study showed that the integrated BIM risk-based procedure was able to improve the accuracy of material requirement estimates and control project schedule changes, thereby supporting the achievement of time targets more optimally.
