The failure assessment of the collapse of the Quebec Bridge in 1907 conducted by the Royal Commission is discussed in the following paper. The Quebec Bridge is a 987.5 m long; 29 m wide; and 104 m high riveted steel truss structure which collapsed not once but twice during construction. The reason for the bridge failure was attributed to member behavior and stability proved by experimental work conducted following the collapse by Royal Commission. The bridge was finally completed in 1917 and has been in operation since then. The lessons learned from the bridge collapse were pivotal in the advancement of engineering design, fabrication and formation of the two organizations, namely - the American Association of State Highway and Transportation Officials (AASHTO) in 1914 and American Institute of Steel Construction (AISC) in 1921. The author highlights the importance of validating the design criteria and specifications by material and load testing, conducting peer reviews, design control, and paying attention to details. The lessons learned reinforce the need to establish and monitor shop fabrication practices, inspection procedures and gates (witness, hold and review points) to safely complete the execution of any civil engineering project, be it onshore or offshore construction.
