ISM-based analysis of influencing factors and countermeasures of construction safety

Abstract

Through the systematic analysis of causing factors of the construction safety accidents, the relationship among 12 causing factors was confirmed. By using ISM theory, the hierarchical ISM model was constructed, which assort all causing factors of construction safety accidents into three hierarchies. The direct reasons are construction workers' safety awareness and safety equipment and facilities. The indirect reasons are machinery and equipment maintenance and improvement, labor intensity, inputs of security cost, and construction schedule. The root reasons are construction safety laws and regulations, and quality of managements. According to the search results, root reasons are vital influencing factors, which are in-depth and fundamental. Besides, construction safety accidents analysis proved the applicability of the ISM model. © 2014 Springer-Verlag Berlin Heidelberg..
