How to create BBS for neck column calculation

This construction video briefly describes how to produce bar bending schedule for measuring the quantities of neck column.

Neck column stands for a column that is located among foundation and grade beam. It originates from footing and finishes at the ground level.

Here the depth of neck column is taken as 1500 mm. If it is viewed from top position, the length is taken as 0.3 m, breadth 0.45 m and depth 1.5 m.

The volume of concrete can be detected with the following formula :-

Length x breadth x depth m3 = 0.3 x 0.45 x 1.5 m3

Shuttering Area = (Length + Breadth) x 2 x Depth m2
= (Peripheral area of neck column) m2
= (0.3 + 0.45) x 2 x 1.5 m2 = 2.25 m2

Bitumen Paint Area = (Length + Breadth) x 2 x depth m2
= (Peripheral area of neck column)
= 2.25 m2

To get complete details for the calculation, go through the following video.
