Special Inspections
The sudden collapse of Ynys-Y-Gwas bridge in 1985 caused concern over the durability of post-tensioned structures. Demolition of other structures has proven these fears to be real.
Unlike many types of construction, post-tensioned structures show little or no signs of distress despite holding severe defects. Because of this, inspection methods need to be more vigorous.
As post-tensioned cables are buried within the concrete, intrusive methods of inspection are necessary. If not reinstated properly these locations can be a source of further deterioration. Destructive methods could also further weaken an already highly stressed structure.
