What is the Rebar Schedule (BBS)?

PlanEsti's Steel BBS (Bar Bending Schedule) Calculator is the most comprehensive reinforcement estimation tool available. Create detailed bar bending schedules for beams, columns, slabs, footings, and any structural element. The tool supports all standard bar shapes as per IS/BS codes, calculates cutting lengths with bend deductions, computes steel weight by diameter, and generates professional BBS reports ready for the fabrication yard.

FAQ

Frequently Asked Questions

Common questions about the Rebar Schedule (BBS).

What bar shapes does the BBS calculator support?

All standard shapes as per IS:2502 and BS:8666 including straight bars, bent bars, cranked bars, stirrups (rectangular and diamond), hooks, U-bars, and helical reinforcement.

How are cutting lengths calculated?

Cutting lengths are calculated using the standard formula with automatic bend deductions based on bar diameter, bend angle, and mandrel size as per applicable codes.

Can I group bars by structural element?

Yes, you can organize bars by member reference (e.g., B1 for Beam 1, C2 for Column 2) and generate summaries per element, per floor, or for the entire project.
