The American Concrete Institute (ACI) has announced the release of the ACI 562-19 Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary.
The institute says the ACI 562-19 was developed to integrate with the International Code Council’s International Existing Building Code or to be adopted as a stand-alone code. ACI 562 is written to be integrated into building codes as a mechanism to provide building officials with more confidence that repairs are carried out in a way that offers accepting protection for the public.
Michael L. Tholen, ACI managing director, engineering and professional development, says: “This third edition of ACI 562 provides all parties involved in a concrete repair project with a common and clearly defined set of requirements upon which to base its assessment, repair, and rehabilitation. ACI 562-19 provides owners confidence that their repair projects will be designed to a common standard, engineers a uniform set of requirements specific to existing concrete structures, building officials a basis upon which to evaluate design and construction, and contractors clarification of responsibilities.”
Key changes to the 2019 version of the code include:
- Improved integration with ACI 318 Building Code Requirements for Structural Concrete;
- Improved integration with the ICC International Existing Building Code;
- More context provided regarding durability;
- Improved text and commentary related to load combinations during fire events;
- Improved text and commentary related to applicability of ACI 562;
- Simplified requirements for the basis of design report; and
- Clarification of requirements related to detailing of existing reinforcing steel.
ACI 562 is immediately available to subscribers of both the online ACI Collection of Concrete Codes, Specifications, and Practices and the ACI Concrete Repair Subscription, or can be purchased individually in print or digital formats.
