ACI Releases Concrete Structure Specs Text
The American Concrete Institute recently announced the availability of a new publication for concrete industry professionals: the ACI 563-18: Specifications for Repair of Concrete in Buildings.
The material is a reference specification that professionals can apply to any construction repair and rehabilitation project involving structural concrete, ACI says. Mandatory requirements and optional requirements checklists are also provided to assist in the tailoring to specific projects.
“The first of its kind, ACI 563-18 joins ACI’s growing family of concrete repair industry documents aimed at demystifying concrete repair and facilitating the delivery of high quality, well-executed, cost-effective concrete repair solutions,” said Tracy Marcotte, Principal, CVM and Chair, ACI Committee 563: Specifications for Repair of Structural Concrete in Buildings.
“ACI 563-18 can be tailored for any project, big or small, using conventional concrete or proprietary repair materials for any project delivery type, from traditional design-bid-build to design-build, and for both private and public projects. Sections include typical concrete and reinforcement requirements plus those particular to repair projects, including shoring and bracing, as well as existing reinforcement and concrete surface preparation. Architects, engineers and specifiers will appreciate the minimum basic requirements encoded into the specification, with guidance included for tailoring companion technical drawings and specifications to communicate specific project needs. Owners and contractors will appreciate the clear delineation of responsibilities, QA/QC and documentation requirements, facilitating no surprises in procurement and execution of the work.”
Provisions on governing testing, evaluation and acceptance of repair materials as well as acceptance of the repair work are also included, and sections nine and 10 incorporate two other specifications—ACI 503.7 and ACI 506.2—to cover crack repair by epoxy injection and shotcrete, respectively.
ACI 563-18 complements ACI 562 Code Requirements for Assessment, Repair and Rehabilitation of Existing Concrete Structures, according to the institute, and the ACI 562 code requirements combine the institute’s historical knowledge with state-of-the-art resources on the evaluation, repair and rehabilitation of concrete buildings.
