A construction worked died Friday after being crushed by concrete forms.
Calgary police say the man was a rigger who assists the crane operator with movement of material on the construction site on 9 Avenue.
Heavy concrete forms were being moved from one location of the 21st floor to another location when the forms shifted in the sling they were being moved in, police say.
The forms slipped out of the sling and fell onto the worker standing below.
He was pronounced dead at the scene.
Occupational Health and Safety investigators and the Office of the Chief Medical Examiner have taken over the investigation.
