Accident of tower crane in USA, in which a Microsoft attorney was killed after a tower crane collapsed onto his downtown Bellevue apartment. An investigation by the state Department of Labor and Industries determined that metal fatigue caused by a design flaw in the crane’s base — which was a steel frame anchored by existing concrete columns rather than a concrete foundation — caused the collapse.
