It details the strand layout including straight bottom strands (grouped as 2-550, 13-350, 2-452, 2-650) and draped strands (2-450, 8-451), diaphragm bar hole locations (omitted at specific beam numbers), camber values, and bearing/hold-down centerline locations, documenting the beam's prestressing and geometric layout for fabrication."
