The American Concrete Institute (ACI) has released ACI 562-19, Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary.

ACI 562-19 was developed to integrate with the International Code Council’s (ICC’s) International Existing Building Code (IEBC) or to be adopted as a stand-alone standard.  ACI 562 was written to be integrated into codes as a mechanism for building officials to have increased confidence repairs are performed in a manner providing an acceptable level of protection for the public.

“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,” said Michael L. Tholen, ACI managing director, engineering, and professional development.

Changes to the 2019 version include:

  • improved integration with ACI 318, Building Code Requirements for Structural Concrete;
  • more context regarding durability;
  • improved text and commentary related to load combinations during fire events and applicability of ACI 562;
  • simplified requirements for the basis of design report; and
  • clarification of requirements related to detailing of existing reinforcing steel.
