Bill of quantities
Describe the building element by element, with real dimensions. Every block, cement bag and kilo of steel is derived from your geometry, not from an average.
This is the mode to use once you have drawings. If you do not have any yet, start with the quick estimator. Quick estimator

The building in a few figures
Everything else follows from these. Every quantity proposed below starts here, and every one stays editable: a figure read off a drawing beats any rule.
What do you want to cost?
Tick what you are building. Nothing appears until you tick it: if you only want the foundation, the foundation is all you fill in.
Ground and foundations
Structure
Envelope
Finishes
External works
You buy the materials and pay the workers directly. No contractor, so no contractor’s profit, but the site costs are still yours.
Not the same thing as the budget estimate’s finish level. A finish level is a different building; a procurement route is the same building bought differently. All three routes below sit inside the estimator’s economy band.
Tick at least one item above to start.
Materials schedule
Quantities pooled across every element, with site wastage added. This is what to order.

The quantities are fixed: they come from your dimensions. It is the prices that vary. Each line shows the quantity, then the unit price from the cheapest merchant surveyed to the dearest. That gap is your negotiating room, not doubt about the building. A tight range: no single line dominates the spread.
Bill total0 ₦ – 0 ₦
This bill covers materials, labour measured trade by trade, plant, transport and fees. The hours come from output rates per element, not from a percentage of the budget.
This bill measures only the works you ticked. Everything can be priced now, from the borehole to the drainage channels: what is missing is what you did not tick. Outside it: the land, the connections to the public networks, and general earthworks across the plot.
Have a technician check this take-off before you order: a mistaken dimension gets paid for in delivered materials.
