Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Net concrete = cylindrical hole volume − embedded post volume. Quantity and allowance are applied before ready-mix conversion and bag rounding.
FAQ
Concrete Bollard Footing Calculator questions
Why subtract bollard displacement?+
The embedded post occupies space that would otherwise be filled with concrete.
Does this determine the required footing size?+
No. Soil, loading, reinforcement and embedment require project-specific design.
Can I estimate sleeved bollards?+
Use the outside diameter of the embedded sleeve or assembly.
