Given Data

• Diameter of Pier: 1.1m
• The thickness of the Pier Cap: 1.5m
• Height of Pier: 5m

Volume of Pier

To determine the volume of the pier, use the cylindrical volume formula:

The volume of Pier Cap

The pier cap consists of two areas, A₁ and A₂.

Calculating A₁

Calculating A₂

or 

Area rectangle

1.2 x 0.5 = 0.6m2

Area triangle

0.5 x 1.9 x 0.5 x2 (for 2 triangle) = o.95m2

0.6 + 0.95 = 1.55m2

Total Area of Pier Cap

Pier Cap Volume

Total Concrete Volume

Summing up both volumes:

 Vtotal = 4.05 + 6.075 = 11 cubic meters.

Conclusion

The total concrete required for the pier and pier cap is approximately 11 cubic meters. This calculation ensures accurate material estimation for construction projects.
