The cause of most formwork failures is not discovered because the rubble covers the strategic information and seldom is the exposure made carefully enough to permit proper obsevation and measurement. Repetitive failure patterns and careful collection of information in several incidents hows a similarity of cause. The avoidance of such detail can reduce the number of future failures. Investigation of reported formwork failures often proves that the proximate cause was not in the formwork but in the structure or foundation supporting the formwork. The forms collapsed even though structurally sufficient. They collapsed because the supporting structure failed or settled differentially.
