Construction is a hazardous process, which is responsible for severe and fatal accidents around the world. The global studies on Occupational Health and Safety (OHS) aspects in the construction industries also reiterated for the improvement of safety culture. The mega projects are projects characterized by vast capital, unorganized work force, technically complex constructions, and having a significant impact on the socioeconomics and community development. For example; highways, power projects, residential buildings, airports, industrial parks, etc. The construction industry is mainly skill oriented and labor intensive. This paper is aimed at studying the prevailing safety practices in the construction of infrastructure power projects in various regions in India in the past 15 years. The study mainly focused on a survey of human practices which are responsible for the behavior at work. The unsafe acts/conditions at work place when uncontrolled lead to incidents/ accidents. The elements identified in the construction process are factored and a safety culture model is developed. The model is based on rock-bottom principles, rigorous approaches and rigid hazard management practices, which is suitable for the construction industry.
