PDF: PTI DC80.1-02: Controlled Demolition of an Unbonded Post-Tensioned Concrete Slab

This report describes the controlled demolition of 100,000 square feet of post-tensioned slab, which was necessitated by suspicion of damage due to fire. The saw-cutting procedure was used to neutralize over 900 post-tensioned tendons. The report illustrates that, if required, slabs constructed with unbonded post-tensioned tendons can safely and readily be dismantled. The report concludes with recommendations for demolition of similar projects.
