Collapse of the Second Narrows Bridge during Construction
On June 17, 1958, 79 workers constructing the new Second Narrows Bridge in Vancouver, BC, Canada, were plunged into Burrard Inlet when a portion of the bridge collapsed during construction, resulting in the loss of 19 lives, including 15 ironworkers, 2 engineers, a painter and a commercial diver who drowned a few days later while trying to recover a body. Twenty others were seriously injured. Following the collapse, the British Columbia Government established a Royal Commission to examine the cause(s) of the collapse and the lessons learned as a result. After an extensive investigation, it was discovered that a temporary bent, designed by an inexperienced engineer and inadequately checked by a senior engineer failed, which lead to the collapse of two spans. Unfortunately, those gentlemen were on the bridge when it failed and both were killed. There are many valuable lessons from the Commission Reports related to the roles and responsibilities of contractor’s engineers in their design of the falsework that was intended to support a portion of span number 5 until the structural steel erection had reached Pier 15 and for the responsibilities and duties of engineers in post-disaster inspections and investigations. This presentation will provide an overview of the collapse and summarize the effects of the disaster and the findings as to what caused the collapse. Some of these lessons will be highlighted in this paper. It was a combination of engineering mistakes, flawed material and procedures, and inappropriate safety standards that resulted in failure. There are numerous incidents of bridge failures after construction. This paper focuses on failure during construction. In 1994, the bridge was officially renamed the “Ironworkers Memorial Second Narrows Crossing” in honour of the workers who died on that day.
