Geometric sweep profile and curvature requirements for post-tensioning tendons incorporate a minimum twenty-one-foot radius with defined offsets and sweep distances. Supplementary reinforcement consists of four number three hairpins spaced at four inches on center with twenty-four-inch legs placed at transition zones along the tendon profile. A coordinate table details specific offset versus sweep dimensions ranging from six inches to three feet of offset and six feet six inches to fifteen feet six inches of sweep.
