Bar Bending Schedule – Importance, advantages, Preparation

What is Bar Bending Schedule (BBS)?

Bar bending schedule is a list of reinforcement bars in a tabular form giving the particulars of bars, the shape of bending with sketches, length of each, total length and total weight. 

Usually, for each type of RCC work, a schedule of bars is usually prepared. With the help of BBS, the requirements of different sizes and lengths of bars may be known and may be arranged and bent-up during the time of construction. It gives information about

  • Particular of size and type of bars
  • The shape of bending with a sketch if any
  • Number of sets or numbers of bars of each set
  • Length of each and total length in running meter
  • Weight per unit length and total weight.

Importance of Bar Bending Schedule

As we know the cutting and bending of steel bar is done by labour at the site. The labour working on site are not so technically sound so it is difficult to explain them with the help of drawing. 

There are chances of wrong cutting and bending of steel. With the help of BBS, it is very easy to explain to them because in BBS shape and cutting length of bars is given. 

A supervisor can easily guide the labours and required work can be done by them as per structural design requirement and specification.
