BAR BENDING SCHEDULE (BBS)
What is a Bar Bending Schedule?
Bar bending is a process there we are calculating a
steel quantity for specific project. Also knows as a short form B.B.S.
In this
process be are know that how much steel quantity need for our project. And also
sure that what are the cutting length of bar or what type are bar used in your
project like 8mm, 10mm, 12mm, 14mm,16mm 20mm etc.
BAR BENDING SCHEDULE (BBS) SO MANY POINTS CLEAR RELATED TO OUR PROJECT
v After
preparing bar bending Schedule we know how much quantity need for 8mm, 10mm,
12mm, etc. Diameter steel bar need for our project.
v Quantity
of bending bar.
v Lapping
for steel bar also know after preparing BBS.
v Cutting
length of your main bar, helical, bar spiral bar.
v Cutting
length of your chair bar, face bar.
v Also
mention are bar bending schedule L- bend size of bar.

HOW TO PREPARE BAR BENDING SCHEDULE (BBS).
Bar bending schedule making is very easy if you know
well study drawing then sure you can do very easy way. But you don’t know how
to study drawing then its difficulty task for you.
But today provide you tow type format for Bar bending schedule
making. That format help you calculate the Bar Banding Schedule very easy way.
1. FORMAT FOR SIMPLE METHOD BAR BEADING SCHEDULE WITHOUT SHAPE OF BAR
REINFORCEMENT DETAILS:
EXMPLE BBS FOR PILE
MAIN BAR BOTTOM CAGE16MM
DIA= 4nos.x 1.58kg x _______Mtr =
kgs.
MAIN BAR TOP CAGE16MM
DIA= 4nos.x 1.58kg x
__________Mtr = kgs.
MAIN BAR BOTTOM CAGE12MM
DIA= 8nos.x 0.89kg x _________Mt = kgs.
MAIN BAR TOP CAGE16MM
DIA= 4nos.x 0.89kg x __________ Mtr
= kgs.
INNER RING 12MM DIA =
1.46Mtr x 0.89kg x
nos. = kgs.
Helicals 8mm dia =______/0.15 x 1.80mtr x 0.39kgs = kgs.
L- Beand 16mm dia= 4nos.x
1.58kg x 0.250Mtr = kgs.
Total= kgs.
