ANALISIS FAKTOR RISIKO PROYEK KONSTRUKSI JEMBATAN (STUDI KASUS PROYEK JEMBATAN DI RUAS PROYEK JALAN TOL PEJAGAN-PEMALANG, PEMALANG-BATANG & SALATIGA-KERTASURA) TESIS (original) (raw)

Risk is a consequence of the uncertain conditions. Risks will always exist on every construction project, since construction projects are essentially unique, dynamic and risky activities. The aim of this research is to analyze the risks of bridge construction projects. While the purpose of this research is to identify the risks, to assess and to manage each risk ifluencing in the bridge construction project. In this research there are two data, that is secondary data and primary data. Secondary data is taken by the method of observation through collecting the risks from research that have been implemented previously. While the primary data taken by the method of communication through interviews and questionnaires. The data obtained then analyzed using the Risk Breakdown Structure (RBS) method and continued by calculating the value of risk importance lavel. Based on these values then determined the categories and conducted ranking of each risk. At the last stage carried out the analysis of the causes, impact and treatment of each risk. The conclusions of this research is the finding 36 risks that affect on bridge construction project which is divided into 6 (six) risk groups: material and equipment risk group, design and planning risk group, HR risk group, financial risk group, risk management group, as well as nature condition and environmental risk group. Based on the assessment and categorization of risk, 1 (one) risk found in the "high" category is bad weather risks, 3 (three) entry risk in the "low" category is risk of error on form, function and specification; inflation; and error risk in the understanding of contract documents, and 33 other risks in the "moderate" category. The risk of bad weather is the occurrence of rain and strong winds that cause work cannot be maximal even stopped for a while and causes transportation to be hampered as an access to project sites becomes muddy and slippery. A possible mitigation measure for this risk is by adding a worker shift, installing tarpaulins for ongoing casting work, use of non-conventional formwork (knock down and fiberglass) and use of additives to accelerate the process of concrete maturation to pursue work delay and considering weather forecasting reports from BMKG to manage work schedule. Regardless of an assessment of the importance level of risk that states the risk of bad weather is the greatest risk, it cannot be denied that bad weather tends to be a seasonal risk, as it only occurs during the rainy season.
