This concrete beam and girder construction joint details the transition between a first and second pour located within the middle third of the span. All primary reinforcing steel continues uninterrupted across the vertical joint interface. Additional ties are spaced at three inches on center typically near the joint for a distance of one foot. Reinforcement sizing varies by member width, requiring one number six bar each way for members up to seven inches wide, two number six bars for widths from eight to twenty inches, four number six bars for widths from twenty to forty inches, and six number six bars for widths exceeding forty inches.
