Risk Analysis of Tower a Development in Surabaya 'X' Project

摘要

The construction of Tower A in Surabaya's "X" Project is one of the largest projects owned by PT X with a construction period of four years. The long period of development will certainly lead to various types of risks that can affect the development of the Surabaya "X" Project. This study aims to identify, assess, rank, and provide mitigation actions against risk factors that can affect the Surabaya "X" Project. This study uses a risk map method to conduct a risk assessment and analytical hierarchy process (AHP) to compare the weighting of each risk factor. Respondents in this study amounted to five informants from different team, consisting of the architect team, civil structure team, project operational controls (POP) team, mechanical, electricity, and plumbing (MEP) team, and site engineering manager team. The identification results obtained 41 risk factors, consisting of 11 risk factors in the architecture section, 11 risk factors in the civil structure, 6 risk factors in the POP section, and 13 risk factors in the MEP section. The results of the assessment and ranking obtained 26 risk factors that require risk mitigation actions, these risk factors consist of 11 factors part of the architecture, with priority being the delay in the completion of the design by the consultant. 6 factors are part of the civil structure, with priority being the mismatch of building structure design. 5 factors are part of the POP, with priority is the unavailability of cash flow. Lastly, the 4 factors of MEP part, with priority is the quality of material that is not according to the specifications. This research is expected to provide a reference material for owners of the "X" Surabaya Project in determining actions against each risk factor that can affect the project.
