Post-tensioned tendon support assemblies utilize continuous chairs, support bars, and slab bolsters resting directly on the structural deck. The chair supports a longitudinal support bar beneath or above the strand cages, establishing the specified center of gravity of steel dimension. Chair heights are calculated using the support bar diameter and one-half of the strand diameter. Cages of strand are positioned as shown on structural drawings and maintained at the exact center of gravity of strand height.
