scope:

This guide describes the responsibilities of various parties involved in assessment, design, execution, and inspection of the rehabilitation of concrete structures in the United States. While the document is primarily directed to projects in the United States, the guidance presented may be applicable to contractual relationships addressing concrete rehabilitation in other parts of the world. Consistent with ACI 562, this guide is applicable for repair and rehabilitation of existing structural concrete buildings; members; systems; and, where applicable, nonbuilding structures including, but not limited to, parking decks, tanks, equipment support frames, and retaining structures.

This guide is not intended to supersede contracts between the parties. If there are inconsistencies between the parties' contracts and responsibilities defined in this guide, then the contracts between the parties govern the relationships and responsibilities. One use of this guide would be to evaluate the balance of the responsibilities associated with concrete rehabilitation.
