Accurate volume calculation is essential in construction projects. It ensures the correct quantity of materials and cost estimation. Below is a clear and simple guide to calculating the pile cap and pile volume.

Given Data

Before starting the calculations, here is the provided data:

• Diameter of Pile = 600 mm
• Radius = 300 mm = 0.3 m
• Height of Pile = 20 m
• Number of Piles = 3

Concrete Volume of Pile

To find the volume of piles, apply the formula for the volume of a cylinder:

Formula:
π × r² × h × number of piles

Calculation:
π × (0.3)² × 20 × 3
= 3.14 × 0.09 × 20 × 3
= 16.956 cubic meters

Thus, the total concrete volume of the piles is 16.956 cubic meters.

Concrete Volume of Pile Cap

The pile cap consists of three parts: A, Bl, and Br.

Volume of Section A

Formula:
L × B × H

Calculation:
3 × 3 × 1 = 9 cubic meters

The volume of Section Bl (left)

Formula:
(1/2) × B × H × Thickness of cap

Calculation:
(1/2) × 1 × 2 × 1 = 1 cubic meter

The volume of Section Br (right)

Formula:
(1/2) × B × H × Thickness of cap

Calculation:
(1/2) × 1 × 2 × 1 = 1 cubic meter

Net Volume of Pile Cap

To find the net pile cap volume:

Formula:
Volume of A – Volume of Bl – Volume of Br

Calculation:
9 – 1 – 1 = 7 cubic meters

So, the net volume of the pile cap is 7 cubic meters.

Final Concrete Volume Summary

• Concrete Volume of Piles: 16.956 cubic meters
• Concrete Volume of Pile Cap: 7 cubic meters
