What is the Bar Bending Schedule (BBS)?
Bar Bending Schedule(BBS) is a list consisting of the detailing of a bar such as mark, shape, dia, dimension of bending, length, weight etc. This article will guide you about different kind of Reinforcement Shape Codes / BBS Formula and Codes.
Represented in tabular form, it is very helpful for projects. In reinforcements, various kinds of bar shapes are used depending upon the load calculation. BBS helps in the calculation of different bar sizes, their cutting, and appropriate use in sites.
Requirements for Evaluating Bar Bending Schedule:
- Steel requirement in projects.
- Monitoring Projects.
- Labour Costs.
- Reconciliation of Materials.
- Steel wastage Control.
BBS Codes:
The Thumb rule is generally applicable for reinforcement evaluation. Large-scale projects usually need codes to prepare bar bending charts and also to avoid wastage of bars. It also helps in the cutting steel as the design requirement.
