At far end, steel frame supports horizontal rebars for cast in place concrete beam. Top steel is supported at proper height by a transverse rebar, and height can be adjusted by small chain fall. Top steel supports U stirrups, which can themselves support horizontal bottom steel. Resteel sags under its own weight and needs additional support along its length. The resteel extends grade beams at near end, which has top steel exposed to bond to concrete slab floor. Colorado Street, Denver, Colorado, December 4, 2006.
