The American Concrete Institute (ACI) recently updated its building repair code for existing concrete structures in 2016 with the new ACI 562-16. The performance-based code makes several changes to the original 2013 version and includes a review of industry terminology to help create a consistent framework to use when working with documents from different sources. ACI 562-16 also defines how to assess an existing structure, strength and durability requirements for repair design, and checkpoints for quality assurance and maintenance discussions between design professionals and building owners.
I recently coauthored an article in the International Concrete Repair Institute’s (ICRI) Concrete Repair Bulletin along with Keith Kesner of CVM Engineers – we are secretary and chair of ACI’s 562 technical committee, respectively. In the article, we describe the performance-based code and explain the changes made in 2016.
