Construction Project Risk at the Toll Road Construction Implementation Phase (Case Study: Solo – Jogja Toll Road Construction Project)

Abstract

The Solo – Jogja Toll Road Development Project is a large-scale project with a large potential risk, especially at the project implementation stage. This research aims to find risks, obtain the level of risk by conducting a risk assessment, and recommend control measures against possible risks. The research method used in this study is HIRARC (Hazard Identification, Risk Assessment, and Risk Control). Purposive sampling was used to collect data from 30 respondents using a questionnaire based on certain criteria. The testing of this research instrument is in the form of validity and reliability tests using SPSS. In this research, 5 risk groups were identified during the implementation stage of the Solo - Jogja Toll Road Construction Project, including project risk, technical risk, natural risk, human risk, and occupational health and safety risk. The results of the analysis explained that the project has a risk range from low to high levels. The risk included in the high-level category is the risk of damage to roads around the project due to heavy equipment, such as dump trucks, project materials carriers, and trucks mixer. The risk can be minimized by creating a safe project access road, so that project activities do not cause further damage to the road.
