Risk Analysis Using AS/NZS 4360:2004, Bow-Tie Diagram and ALARP on Construction Projects of Banyumanik Hospital

The Determination of risk is an uncertain event. Risks can have negative or positive impacts on project objectives. A project was defined as a series of activities and tasks that have a purpose, specifications, and limits of cost. Banyumanik Hospital Development Project is one of the construction projects in Semarang which have experienced some problems. The first problem is project delays on building stake. The second problem is delay of material supply. Finally, the problem that occurs is less management attention to health safety as evidenced by the unavailability of PPE for the workers. These problems will pose a risk to he a very important risk management performed by contractors at the Banyumanik Hospital Development Project to reduce the impact that would he caused by the risk borne by the provider of construction seniices. This research aim to risk identification, risk assessment- and risk mitigation. Project risk management begins with the identification of risks based On the project life cycle. The risk assessment carried out by AS/NZS 4360: 2004 to the impacts of cost, time and quality. The results obtained from the method of AS/NZS 4360: 2004 is the risk that requires the handling of mitigation. Mitigated risk is the risk that had significant and high level. There are four risks that require risk mitigation with Bow-Tie diagrams which is work accidents, contract delays, material delays and design changes. Bow-Tie diagram method is a method for identifying causal and preventive action and recovery of a risk. Results obtained from Bow-Tie diagram method is a preventive action and recovery. This action is used as input to the ALARP method. ALARP method is used to determine the priority of the strategy proposed in the category broadly acceptable, tolerable, and unacceptable.
