Mostly for small house construction, the reinforcement will be calculated just based on the thumb rule. The excess procured steel will be used for other works.

But for a large-scale project, the tedious BBS schedule will be prepared to avoid the unnecessary wastages.

Bar bending shape codes are the cutting length formula used to avoid unnecessary cut wastes on reinforcement.

Advantages of using BBS codes in BBS Schedule

• To minimise the wastage
• To cut the steel bar easily based on the shape code
• To procure the accurate quantity of material

## Standard Bar Bending Shape Codes

 Bar Bending Shape Cutting Length of Bar L = A L = A+B-0.5r-d L = A+B+C-r-2d L = A+B+C-r-2d L = 2(A+B)-2.5r-5d+Hook L = A-3.2D+2Hook L = A+B+2Hook L = A+B+C+D-2r+Hook L = A+B+C L = Cπ(d-A) A-Spacing C-Nos of turns L = A L = A+C L = A+B+C L = A+B+C+D+E L = A+C+D L = A+B+C+D-0.5r-d L = A+B+C+D+E L = A+B+C+D-1.5r L = A+B+2C-2.5r L = 2A+2B-2.5r+2Hook L = A Bala is a Planning & QS Engineer working at Megha Engineering & Infrastructure Limited.
