Risk Management of the Occupational Health and Safety (OHS) Aspects on the Megaprojects of UINSA’s Campus II Development Surabaya

Occupational health and safety (OHS) is an important aspect that determines the successful implementation of a construction project. It is directly related to the effectiveness and efficiency of time and cost. This study aims to investigate the potential and risk of occupational accidents in the construction project of UINSA's campus II, Surabaya, to further formulate a systematic occupational safety and health risk control strategy to support the success of construction projects. This study implements a quantitative method with a survey approach. Primary data were collected using a questionnaire distributed to 35 contractor personnel related to OHS aspects. Analysis of the potential level and risk of work accidents was carried out based on the 2014 AS/NZS 4360 matrix. Based on the results, molding, metal reinforcement, casting, wall, and ceramic installation, door, and window installation, and painting work on UINSA's campus II construction project obtained work accident risks index in the "medium" to "high" category. In addition, the potential risk of work accidents in all types of work is proven to have a significant impact (p < 0.05) on contractor performance in completing construction projects. Therefore, OHS management needs to be the contractor's primary concern to mitigate and prevent potential work accidents in the project environment. The risk control strategy can reduce potential risks by preparing health, safety, and environment (HSE) plans that include HIRARC (Hazard Identification Risk Assessment and Risk Control), implementation of safety induction, and safety patrol and installation of HSE warning signs
