Abstract:
1) During a concrete repair project to a post-tensioned (PT) structure, we removed the patching material in the stressing pocket and noticed cracking in the wedges. Do the wedges need to be replaced? 2) I’m an inspector for a municipal building department, and I recently encountered a foundation subcontractor that insisted on placing reinforcing bars just ahead of the flow of concrete coming out of the pump hose. Is that acceptable?
