Variables Explained
| Input | What it means |
|---|---|
| Construction Type | Choose the applicable option; it determines which relationship or conversion the page applies. |
| Covered Area | Surface size in square units. Covered area is different from a plot’s total land area. |
| Number of Floors | Number of floor levels included in the total covered-area assumption. |
| Cement (per bag) | Use the measured or stated value for this item, with the unit or category shown beside the field. |
| Bricks (per 1000) | Use the measured or stated value for this item, with the unit or category shown beside the field. |
| Sand (per cft) | Use the measured or stated value for this item, with the unit or category shown beside the field. |
| Crush (per cft) | Use the measured or stated value for this item, with the unit or category shown beside the field. |
| Steel (per ton) | Use the measured or stated value for this item, with the unit or category shown beside the field. |

Worked Example
Two floors of 1,000 ft² each at an assumed rate of 150 per ft² give a base estimate of 300,000 before extra allowances.

Why Use This Calculator?
Treat the result as a planning allowance. A measured bill of quantities and current supplier quotes are needed to price a specific design.
7
Common Mistakes
- Avoid counting floor area twice. Unit rates and material quantities vary with drawings, specification, location and date.

Frequently Asked Questions
Is this a contractor’s quote?
It is an estimate from the inputs and assumptions on this page. It does not establish a scope of work, an agreed price or the actual quantities required by the drawings.
When should I round a measurement?
Carry the measured values and conversion factors through the calculation first. Round the final result to a precision justified by the original measurements.
