Evaluating and mitigating risk of an automated people mover system project: a case study

Abstract

Risks describe as the situation of uncertainty. Risks will appear on every construction project, including an Automated People Mover System (APMS) project. The length of APMS track is 3.05 kilometres to connect Soekarno-Hatta Airport terminals 1, 2 and 3. Track APMS is a bridge structure with a simple concept span. Girder was designed with the PC-V concept. More complex project causes various risks. Therefore, to deliver complex projects to success, the risks should be managed. It is important to handle the risk by applying risk management. Risk management has 3 stages: risk identification, risk analysis and risk response strategy. This research was organized through questionnaire and interview with contractor in APMS project. Risk identification using Risk Breakdown Structure (RBS) method. Then the result of risk identification will analyze using probability and impact matrix. The matrix were aimed to earn the risk category and classified into 3 groups i.e. high, moderate, and low. Risk response strategy is to minimize the impact of risk occurence. This research identified 25 risk factors that consist of 7 category: design risks, time risks, material and equipment risks, financial risks, resources risks, managerial risks and external risks. Delay in relocating existing facilities and girder damage risks are the higest risk, both risk should be avoidance. This study purposed to identification and mitigate risks. These findings were valuable for contractor to mitigate risks especially with the same project characteristics.
