Risk Management Analysis and Mitigation Cost Calculation in the Riyadlus Sholihin Islamic Boarding School Dormitory Construction Project

Abstract

Construction projects often encounter a range of challenges that can threaten the success of their implementation, with delay being one of the most significant risks. Such delays may directly lead to increased project costs, compromised quality, and disruption of scheduled project completion. This was evident in the construction of the Santri Dormitory at the Riyadlus Sholihin Islamic Boarding School, where delays persisted despite the implementation of acceleration measures. Therefore, identifying risks systematically and developing effective mitigation strategies is crucial to anticipate and manage potential barriers during the construction process. This research applies a descriptive quantitative method, using questionnaires distributed to project stakeholders for data collection. The Severity Index (SI) method is utilized to evaluate the probability and impact of each risk variable. The results are then plotted on a Probability-Impact Matrix to determine the severity of each risk. Five risks categorized as "very high" were selected for further examination, where suitable mitigation strategies were designed and the necessary contingency costs estimated using the single value method, following approaches from previous research. The study revealed five key risks, such as the development of inadequate work methods, lack of coordination between departments, and low workforce productivity. The mitigation measures proposed are considered practical and feasible, with an estimated mitigation cost of IDR 43,950,000, representing 0.541% of the total project budget. These findings indicate that applying structured and quantifiable risk management can effectively reduce delay impacts and contribute significantly to the overall success of the project.
