This article reports a study on the construction of a food factory building in Indonesia by investigating the root causes of time overruns from the perspective of a consultant. Although many risks have been identified at various stages of the construction project, it is not clear which risk is the main cause of project delays. To better understand the optimization of risk management and risk mitigation, a multi-stage risk management is proposed, which is divided into four phases: pre-design, design, project bidding, and construction. Therefore, the use of bow tie analysis allows for more in-depth inspections to identify risks. From each bow tie diagram, a detailed risk mitigation table can be developed, and it is easier to plan the response to each risk. From this research, the top 5 reasons for the delay of the project were found. The first reason for the delay is X3a2, which has a value of 4.578, which is a change in design idea. The second value of X3c1 is 4.533, which is the technical data of new machines appearing. The third row is X2b4, the value is 4.467, waiting for owner's decision. The fourth place is the variable X1b3 Machine technical data appears after tender, with a value of 4.422, and the fifth place is the difference between local regulations and foreign regulations, with a value of 4.378.Keywords: factory building, risk management, time overrun.
