Pre-stressed Concrete Structures

The most important aspect of demolishing a pre-stressed concrete structure takes place during the engineering survey.

An engineering survey must be completed before demolishing pre-stressed concrete structures.

During the survey, a qualified person should determine if the structure to be demolished contains any pre-stressed members.

It is the responsibility of the demolition contractor to inform all workers on the demolition job site of the presence of pre-stressed concrete members within the structure. They should also instruct them in the safe work practice which must be followed to perform the demolition safely. Workers should be informed of the hazards of deviating from the prescribed procedures and the importance of following their supervisor's instruction.
