Reinforcement bar stock.
Transcribe the lengths and counts from the supplied reinforcement schedule.
Read the right quantitative data
Stock lengths, specified laps and cut allowances already established by the design.
Check this ordering assumption
Counting intersections or area alone does not produce a bar cutting schedule.
Quantity tools do not choose bar size, spacing, cover or required reinforcement.
