Let us consider a column as shown in the below-given drawing.
Given data:
Column size = 230mm. × 300mm.
= 0.23m. × 0.30m.
Height of the column = 3m.
Before proceeding further, Go through the article👇
👀. What will be the construction cost of a 3m. height RCC column?
1. Column concreting:
The labor rate of column concreting will be between INR 600/- to 1000/- per CUM.
Let us take the average rate of INR 800/- per CUM.
The labor cost of column concreting
= [total vol. of concrete in CUM × rate/CUM.]
=[0.207 CUM × 800/-]
= INR 165.60/-
Note: The vol. of concrete is taken from the above-linked article.
2. Reinforcement:
The labor rate of column reinforcement work will be between INR 9/- to 15/- per kg.
Let us take the average rate of INR 12/- per kg.
The labor cost of column reinforcement
= [total wt. of steel in kgs. × labor rate/kg.]
= [ 23.81 kg. × 12/-]
= INR 285.72/-
Note: The wt. of steel is taken from the above-linked article.
3. Formwork:
The labor rate of column shuttering work will be between INR 11/- to 17/- per sq ft.
Let us take the average rate of INR 14/- per sq ft.
or INR 150/- per sq m.
The total area of shuttering work
= [(area of width side) + (area of length side)]
= [( 2nos. × 0.23m. × 3m.) + (2nos. × 0.30m × 3m.)]
=[ (1.38sq m.) + ( 1.80 sq m.)]
= 3.18 sq m.
The labor cost of column formwork
= [total area of formwork in sq m. × labor rate/sq m.]
= [ 3.18 sq m. × 150/-]
= INR 477/-
The total labor cost of column
= cost of [ concreting + reinforcement + formwork]
= [165.60/- + 285.72/- + 477/-]
= INR 928.32/-
