DISASTER RISK MITIGATION IN THE IMPLEMENTATION OF CORE CONSTRUCTION IN KUWIL KAWAN
Abstract
This study endeavours to undertake a comprehensive analysis of disaster risks associated with the execution of essential construction activities at the Kuwil Kawangkoan Dam. The research involves a participant pool of 42 individuals engaged in the project, with a determined sample size of 30 employing the Slovin formula. The data collection methodology encompasses both quantitative and qualitative techniques, incorporating interviews, questionnaires, and observations. The analytical approach employed is disaster risk analysis, utilizing the formula R = H x V/C. The results uncover a spectrum of challenges, ranging from high-risk factors such as difficulties related to soil excavation to moderate and low risks, including design inconsistencies and weather-induced material damage. Noteworthy vulnerabilities identified encompass residences and critical facilities susceptible to flooding, underscoring the imperative need for robust risk reduction measures. Although the project demonstrates strengths in disaster management policies, identified weaknesses in systematic preparedness necessitate a more cohesive and integrated approach. The theoretical contribution of this study lies in its universal risk assessment, incorporating multiple dimensions to provide a nuanced comprehension of project vulnerabilities. From a practical standpoint, the research proffers tangible mitigation strategies tailored to specific risk levels, furnishing stakeholders with guidance for proactive risk management. Serving as a foundational reference for analogous construction endeavours, this research advocates for a holistic risk management approach spanning the entire project lifecycle, from planning to execution.
