In the construction industry, the rate of work-related injuries and deaths is two or more times the national rate for all industries. This paper develops a rational method which quantitatively rates construction risks, using risk scores. The scores, which are computed for each workmen's compensation classification, are based on insurance premiums and injury cause-cost analysis. In addition the method numerically ranks the relative cost effectiveness of corrective actions which are taken to reduce risks. The cost effectiveness ranking is determined from the risk score, the cost and the degree of effectiveness of the corrective action. Use of the method can improve the efficiency of evaluating risks and allocating resources to minimize the risks. The method presented is considered only a first step. The uses, limitations, and further development of the method are presented.
