Project Performance Through an Occupational and Health Safety Management System at an Office Building Project in Lampung Indonesia

Abstract. A project contractor may fail to deliver on time, quality, and budget expectations due to incidents resulting in injuries and fatalities, as well as asset damage, elevated costs, and delays. This research aims to gauge a business improvement model on OHS (occupational and health safety) performance developed from operation standardization, communication, competency, hazard identification, and management commitment. Commitment initiates risk analysis for developing standardization, communication, and competency to achieve OHS performance. The present case study concerns a contractor establishing a local government office building in Lampung. It takes 100 respondents as a sample out of the 124 personnel in this construction project, relying on a quantitative method which processes data via PLS software to obtain the direction and magnitude of variable influences. OHS policy exhibits influence at 0.587 on HIRADC (Hazard Identification Risk Analysis and Determining Control); it affects standardization, competency, and communication at the values of 0.704, 0.450, and 0.300. The three variables then simultaneously affect OHS performance at the values of 0.540, 0.065, and 0.116. OHS performance affects business performance at a value of 0.384.
