Sawant 1 * S. S.

The main objective of this research was to identify the factors affecting occupational health risk during construction of high rise building & to assess the risk during different construction activities. In the present study, field survey is done at forty two sites in western Maharashtra such as construction sites in Pune, Satara, sangli and Kolhapur city and data is collected for assessment of risk causes affecting occupational health in construction. In this study various risk causes were found out with help of questionnaire survey. These questionnaires were given to the experienced site engineers and data were collected. These data was then analyzed with the help of two different methods, named Relative Importance Index method and T-test analysis using SPSS. Results were calculated and shown with the help of graphical and tabular representation.

INTRODUCTION In general meaning of the risk can be defined as ―action that endangers something what has a value‖. Construction sector is one of the most influenced segments of the unorganized labor in our country. Recently, Indian construction industry has experienced considerable growth in construction activities. The high rate of urbanization and Infrastructure development in India shows the demand of residential & commercial consumers. This results as increase in number of construction Projects by creating an employment opportunity for wide range of labor force such as skilled worker, semi-skilled worker & unskilled worker. The sector is labor-intensive and including indirect jobs, provides employment to more than 35 million men power. Throughout the world, most adults and many children spend much of their waking hours at completing task associated with work. Work gives a number of income sources and other remuneration. Despite its importance, construction sites have been regarded as very risky areas where construction workers are subject to fatalities and ill-health problems. Many building construction activities are inherently risky to health and safety of workers. It affects to productivity & overall performance of construction project & diminishing the workforce/labor force etc. Efforts are focused towards finding solution to assess risk at construction projects. Risk assessment is one of the integral parts of occupational health and safety management plan. Risk assessment helps to find out causes of risk as well as create awareness of risk and hazards and also finds who may be at risk. The idea to assess risk even at the comparatively smaller construction activities like construction of residential and commercial high rise building complexes is found new but important and determination of occupational health risk assessment is found essentially needed in future. II. FACTORS AFFECTING OCCUPATIONAL HEALTH RISK Factors affecting occupational health risk during construction are identified from literatures & also with the help of experts in the field of construction. Total 12 factors was identified, e.g. Workers instincts, workers capabilities, communication between the workers and between workers and supervisors, condition of tools & equipments, safety culture, etc. The factors are then listed & grouped in 12 factors. Then finally regrouped into 5 main groups as shown in fig 1.
