Analysis of the Relationship Between WBS, SOP, BIM, LS, and IS for Dam Maintenance

Abstract

Dams are critical national infrastructure assets that the Indonesian government has developed extensively over the past decade to improve water security and mitigate the impacts of drought and extreme weather events. This large-scale development has created increasing demands for effective and sustainable dam maintenance. At present, dam maintenance activities have not been systematically implemented using a Work Breakdown Structure (WBS)-based approach. Ideally, maintenance performance should be optimized by first identifying the complete scope of maintenance components and then developing maintenance guidelines and Standard Operating Procedures (SOPs) for each identified component. These WBS-based maintenance procedures and guidelines can subsequently be integrated into a maintenance management model using Building Information Modeling (BIM). To support real-time monitoring and inspection, laser scanning (LS) technology can be integrated with BIM and information systems (IS). This study forms part of the development of an electronic dam maintenance (e-maintenance) system by examining the relationships among the key components of the proposed framework, namely WBS, Standard Operating Procedures (SOPs), BIM, laser scanning (LS), and information systems (IS), and their influence on improving dam maintenance performance. Multiple regression analysis, followed by expert validation, was employed to evaluate the significance of these variables in the proposed dam maintenance system. The results indicate strong relationships among the variables, with correlation coefficients ranging from 0.714 to 0.822. Among the variables, WBS exhibited the strongest influence on dam maintenance performance, with the highest standardized regression coefficient (b = 0.237), whereas the remaining variables produced coefficients ranging from 0.048 to 0.173.
