This is a very useful construction article for construction professionals. The article will provide detailed guidelines for preparing bar bending schedule for steel.

Bar bending schedule alias schedule of bars refer to a list of reinforcement bars concerning a specified RCC work item. Bar bending schedule delivers the reinforcement calculation toward reinforced concrete beam. It is demonstrated in a tabular form. The table sums up all the required particulars of bars which range from 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.

Here, in this article, the diameters of steel bars are taken as 8 mm, 12 mm, 16 mm, 20 mm and 24 mm.

In bar bending schedule, there are several heads like serial number, description (provide beam, slab for which steel quantities should be measured), number of bars (how many numbers do you have), diameter, length (steel), unit weight (steel), total weight and remarks.

The following formula should be used to find the unit weight of steel per meter.

D²/162

Therefore, for 8 mm dia, unit weight will be 82/162 = 64/162 = 0.395 Kg/per meter

You can use this formula for other diameters of the steel bars.

In description, put Beam i.e how many steel quantities are required for beam. In number section provide the numbers of bars (here 1 is given). In dia section, give 8 mm. In length section, put 14 ft as length of steel and convert it to meter by dividing it with 3.28 as 3.28 ft is present in 1 meter. After dividing we get 4.307. The unit weight is 0.395 (this is the per kg length of steel for 8 meter dia). Now, to get total weight, multiply unit weight with length i.e. 0.395 x 4.307 = 1.701 kg.
