How do you prepare bar bending schedule and also write down the advantage?

Advantages of Bar Bending schedule

  1. There is faster execution of work at the site with the help of BBS, which reduces construction cost and time.
  2. BBS reduces reinforcement wastages in cutting.
  3. BBS helps in improving quality control at the site.
  4. It helps in stock management at the site.

What is the purpose of preparing BBS?

Bar Bending Schedule helps the quantity surveyor to consolidate the number of bars required of each bar type. This leads to an estimation of the quantity of steel, which translates to the cost requirements for steel work. Hence, BBS is used by the contractor who orders the reinforcements as well.

How do you take BBS?

To understand clear, Here I am considering the below structural member RCC Column and preparing a BBS for it….How to Prepare Bar Bending Schedule:

BBS of Column
No. of Bars used 1. Main bars = 4 2. Stirrups = 30
Cutting length 1. Main bars = 3.16m 2. Stirrups = 2.64m

How do you solve a bar bending schedule?

Bar Bending Schedule for Reinforced Concrete Beam

  1. Length of B1 = clear distance between walls + 2 x width of walls – 2 x bar cover + 2 x bend length.
  2. Length of bar B2: A + B + C = 4000 + 2 x 230 – 2 x 40 + (1.414xH – H)
  3. B2 = 4000 + 2 x 230 – 2 x 40 + (1.414×334 – 334) = 4518.3 = 4520mm.

What is BBS construction?

Bar Bending Schedule (BBS) helps to determine the quantity of steel required in construction of your house. This helps to get the accurate estimation of steel. Once the calculation of cutting and bending is done it reduces the wastage of steel and it becomes economic.
