  What is a Bar Bending Schedule (BBS)? 1. Definition A Bar Bending Schedule is a structural list or spreadsheet that provides complete details of every reinforcing bar (rebar) required for a concrete structure (such as footings, columns, beams, or slabs). A standard BBS tells the site execution team: The exact Shape and bending angles of the rebar. The Cutting Length (the total length of the bar before it is bent). The Diameter/Size of the bar (e.g., 10mm, 12mm, 16mm in the UK, or #3, #4, #5 in the US). The Total Quantity and total Weight of steel required. 2. Why is BBS Essential? (Benefits) Drastic Waste Reduction: Ordering pre-cut or knowing the exact cutting lengths beforehand minimizes steel scrap on-site. Accurate Procurement & Estimating: You know exactly how many tons or pounds of steel to order from the mill, preventing under or over-ordering. Faster Site Execution: Fabricators and steel fixers can cut and bend rebar systematically looking at the schedule, k...
