What is Bar Bending Schedule and Why Do You Need It?

Bar bending schedule, or BBS, is a list of reinforcement bars for any structural element that gives the mark, type, size, location, length, number, and bending details of each bar or fabric. It is a tabular representation of each reinforcement bar used in reinforced concrete work. It is also called scheduling.

Bar bending schedule provides details of reinforcement cutting and bending length. It helps in improving quality control at the site, reducing reinforcement wastages, estimating steel quantity, managing stock, and auditing reinforcement. It also allows cutting and bending of reinforcement at the factory and transporting them to the site, which increases faster execution and reduces construction time and cost.

Bar bending schedule is used for different structural elements such as beams, columns, slabs, foundations, staircases, etc. It is prepared in accordance with the respective detailing standard codes such as BS 8666: 2020 in the UK, IS 2502: 1963 in India, ACI 315-99 in the US, etc.

How to Prepare a Bar Bending Schedule?

Preparation of bar bending schedule should begin with the appropriate study of the reinforcement detailing drawings. All inconsistencies or errors discovered in the drawing should be reported to the detailer, because the details of the structural drawing and the bar bending schedule should be synchronised.

The basic steps and formulas for BBS preparation are as follows:

• Find the number of reinforcement bars to be used

• Find the cutting length of each bar using the formula: Cutting length = Total length Bend deduction

• Find the number of stirrups or distribution bars if it is a beam or slab respectively

• Find the bend length using the formula: Bend length = Angle/360 x (Dia x π)

• Find the hook length using the formula: Hook length = 9d for 90 hook or 12d for 135 hook

• Find the lap length using the formula: Lap length = 40d for tension bars or 50d for compression bars

• Find the development length using the formula: Development length = φ x σbd / (4 x τbd)

• Find the total length and weight of each bar using the formula: Total length = Cutting length + Bend length + Hook length + Lap length; Weight = Total length x Unit weight

• Summarize all the details in a tabular form with headings such as Bar mark, Shape code, Dia, No. of bars, Cutting length, Total length, Weight, etc.
