Video Summary

Kevin Krawick, a seasoned structural engineer, discusses the similarities and distinctions between code 301 and the new specification 563 for concrete repair. Both documents share five main sections: general requirements, formwork, reinforcement, concrete mixtures, and handling. While 563 is inspired by 301, it focuses exclusively on repairing existing concrete structures. It incorporates unique definitions, requirements for engineered and non-engineered formwork, and emphasizes repair-specific issues like shrinkage, curing, and dealing with existing structural tolerances. Krawick notes that 563 is intended for standalone use, typically after the issuing of an occupancy permit.
