RCC drawings so that you can find out the following values from the drawing :
Length of the element :
No of bars
Type of bars
Spacing between the bars.
Lap length ( horizontal/vertical)
Covers for footing/column/beam/slab.
2. Calculate the cutting length of the bars.
( total length – covers on bothside )+ development length.
W = N*CL*U
W: Weight of reinforcement
N: No of bars
CL: cutting length
You can find out Unit weight from charts or from the formula :
