Multiphase Project Risk Management on Food Factory Building Construction: Consultant Perspective

Abstract

: This article reports research on a flour mill factory building construction in Indonesia by investigating the root cause of time overrun in consultant perspective. While numerous risks are identified during the phases of construction project, it is unknown which risk is the primary cause of project delays. To better understand the optimization of risk management and risk mitigation, a multiphase risk management is proposed, which is divided into 4 phases: pre-design, design, project bidding, and construction phase. As a result, employing the bow-tie analysis enables a more in-depth examination to identify the risk. From each bow-tie diagram, a detailed risk mitigation table can be formulated and easier to plan the response for each risk. Probability Impact Matrix also used to identify the risk score and evaluate the risk. This research begins by giving questionnaire to 45 qualified respondents. It was found that 45 factors that caused the delay in all phases were divided into 7 factors from the pre-design phase, 14 factors from the design phase, 6 factors from the tender phase and 16 factors from the construction phase. As the final step of risk management process, there are various responses in this research depends on their final assessment based on the score and questionnaire result. Factory building construction is quite different from other type of building construction because machine design also being an important part that affects the structural, architectural, mechanical and also electrical aspects.
