What is BBs steel?
Bar bending schedule or schedule of bars is a tabular representation of reinforcement bar. It is generally represented for each type of R.C.C work. Bar bending schedule generally describes the particulars of bars, shape of bending with sketches and total length and weight of the bars along with their numbers.
How do you calculate BBs of steel?
Details Obtained from Structural Drawing
- Length of Footing = X.
- The breadth of Footing = Y.
- The height of the footing (Thickness) = h.
- The diameter of the Main reinforcement bars = d. m
- The diameter of Distribution Reinforcement Bars = d. d
- The spacing of reinforcement bars = s.
- Cover for reinforcement = c.
How does BBs calculate number of bars?
No of vertical bars = 6 nos. the diameter of the vertical bar = 16 mm. Diameter of stirrup = 8 mm….HOW TO CALCULATE THE QUANTITY OF STEEL IN COLUMN (BBS)
| SIDE A | SIDE B |
|---|---|
| A =500 – 2 Side clear cover A = 500 – 2 x clear cover A = 500 – 2 x 40 A = 500 – 80 A = 420 mm | B =400 – 2 x Top & Bottom cover B = 400 – 2 x clear cover B = 400 – 2 x 40 B = 400 – 80 B = 320 mm |
What is BBs and why it required for rebar work?
Table of bar bending schedule summarizes all the needed particulars of bars – diameter, shape of bending, length of each bent and straight portions, angles of bending, total length of each bar, and number of each type of bar. …
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.
Why bar bending is done?
Advantages of Bar Bending schedule There is faster execution of work at the site with the help of BBS, which reduces construction cost and time. BBS reduces reinforcement wastages in cutting. BBS helps in improving quality control at the site. It helps in stock management at the site.

What is bar bending?
Bar bending is the manufacture and bending of the steel reinforcing bars and beams, also known as rebar, used as reinforcement in concrete construction. This gives the manufacturers the proper bends and tensile strengths of the steel required to make certain shapes or other concrete constructions that are required.

What is the BBS of a bar?
It includes the cutting and bending length of bar according to bar diameter. For any heavy or complex structure, its reinforcement calculation is very difficult so we are providing a simple calculation sheet for BBS in Excel sheet.
What is Barbar bending schedule?
Bar Bending Schedule is a list of bar according to the drawing of any structure or element. It includes the cutting and bending length of bar according to bar diameter. For any heavy or complex structure, its reinforcement calculation is very difficult so we are providing a simple calculation sheet for BBS in Excel sheet.
What is the importance of the BBS in steel engineering?
BBS helps to estimate the total quantity of steel required for the construction of building or structure. It helps to quote for tender the cost incurred by steel. Finding the cutting length and bending length in reinforcement detailing improves the quality of construction and minimize the wastage of steel, makes an economic construction
