710.1 Construction Inspection for Sec 710

Shipping damage
Epoxy splitting

Those provisions of Sec 706 concerning placement and location of reinforcing steel apply to epoxy coated reinforcing steel. The reinforcing steel should be inspected for damage to the coating. Any damaged areas should be repaired with epoxy patching material furnished by the manufacturer.

While torch cutting is acceptable to shorten uncoated resteel, in no case should a torch be used on epoxy coated resteel. Any long epoxy bars should be saw cut and the ends patched with patching material approved by the coating manufacturer.

During placement the inspector should caution the contractor not to damage the coating and make sure the proper vibrators are used.
