Bridge Collapse during Demolition
This paper presents the results of an investigation into the total collapse of a 100-foot-long span of a bridge during demolition. The bridge was a steel-framed structure with a composite concrete deck. At the time of the collapse, the deck had been sawcut transversely and longitudinally, and a large excavator was hammering the deck to release it from the steel girders. The entire span collapsed, causing the excavator and the operator to fall with it. The operator was injured, the bridge replacement project was delayed, and litigation followed. This paper presents the deficiencies in the demolition plan and execution, which led to the collapse. It also discusses the legal proceedings that followed, focusing on the various expert opinions and their basis. This paper also provides recommendations to owners, engineers, and contractors to prevent the occurrence of similar bridge collapses and also recommendations related to performing investigations that are used for litigation.
