Concrete Demolition Unknowns (job site surprises that shouldn't surprise a demolition contractor)

Most concrete contractors, even though not demolition specialists, will have to demolish portions of structures as a part of their usual business. Knowing which method or combination of methods to use for demolition of reinforced or prestressed concrete structures is essential for a safe and profitable job.

Demolition work involves many of the hazards associated with construction. However, demolition incurs additional hazards due to unknown factors such as:

  • Deviations from the structure's design introduced during construction
  • Approved or unapproved modifications that alter the original design
  • Materials hidden within structural members
  • Unknown strengths or weaknesses of construction materials used on the project.

Many concrete contractors specialize in jobs that include demolition. Some contractors only do demolition- and leave the concrete construction to other concrete contractors.
