Section 15 Concrete Reinforcement - NYSDOT Home

15.4.2.2 Splicing Vertical Reinforcement in Walls For #5, #6, and #7 bars, the splicing of the main vertical reinforcement to the reinforcement emerging from the footing may be made directly over the footing. In some cases, it may be practical to eliminate splices by extending the bars emerging from the footing to the top of the wall.
