Structural Failures During Construction

Structural failures involving components, assemblies or partially completed structures often occur during the process of construction. Many minor failures are not reported in the media, but these events contribute cumulatively to the costs of construction. Significant catastrophic collapse is always economically disastrous, and may result in injury or death to construction workers. An overview is presented of the factors contributing to the frequency of these occurrences, and to the vulnerability of structures during the construction phase. Recommendations for improved practices are also presented. Public interest has recently focused on the safety record of the construction industry, with over 2,200 deaths recorded in 1984. The inherent risks in construction arise from a variety of causes, including excavation problems, equipment failures, and trenching accidents. Understanding and minimizing the potential for structural failure during construction is one important aspect in the improvement of the constr...
