The man was injured in March 2009 while using a jack hammer to demolish part of a wall.
He had been ordered to use the equipment while standing on a plywood platform erected as formwork for a concrete pour.
He fell about 3 metres to the floor below when a piece of the formwork flipped.
The Court heard he suffered injuries to his right shoulder and elbow and had not been able to resume work after having two operations.
The man was awarded more than $ 100,000 in compensation for his injuries and more than $ 400,000 for lost past and future income.
