Construction industry is an important growth indicator because it generates investment opportunities across multiple related sectors. The construction task or work environment is very risky and hazardous and its susceptibility to accident. The major cause of the accident is the employees' poor safety performance in construction sites. These root causes of accidents and factors influencing them need to be studied in order to improve safety results. In pipeline sleeper construction, safety is a dynamic decision issue close to normal construction cases. The study identifies the critical risk factors affecting the safety performance and ways to achieve sustainability in pipeline sleeper construction to counteract the risk of accident occurrence. Based on the evaluation of the questionnaire survey, the study explains twelve most important factors and sub factors, which were rated to have more than a moderate effect on safety performance. The six keys to sustainable success for integrating worker protection in the assessment of sustainable construction is also discussed. Keywords-Hazards, pipeline sleeper, safety performance, risk
