Risk assessment on safety in construction site

Abstract

Problems on occupational safety and health are commonly occurred in the construction industry, including falling from height and falling of materials. The key of dealing with project safety and risk assessment in construction industry is important. This study is carried out to determine the safety risk factor occurred on site and after the risk factor have been identify, risk assessment is conducted. The objective of this study is to determine and analyze the safety risk factor in construction site. Failure Modes and Effects Analysis (FMEA) method is used to assess the risk factor in the construction site by taking consideration of occurrence, severity and detection. In this study, a total of 22 safety risk factor was determined. Questionnaire had been distributed to the project team members in construction site around Kuching and Johor Bahru. The completed set of questionnaires was received from 8 out of 10 different construction sites. The project team members of each site consist of client representative, project manager, engineer, architect, safety officer and site supervisors. The collected data was analyzed through frequency analysis, average index analysis and FMEA. The risk factor that has the most occurrences is scaffolding falls?. The risk factor that has the most impact is „building collapse? while the „crane falls on construction site? has low chance to be detected. After that, the safety risk factor is rank based on Risk Priority Number (RPN) and the level of acceptability and the consequences is graded. The findings indicated that „roof related falls?, „crane falls on construction site?, „scaffolding falls?, „hit by falling objects?, „scaffolding accidents?, and „fatal electric shock? are graded as unacceptable
