Basic BOQ Generator

About this tool

Build a simple bill of quantities for a small job: sections or trades, item descriptions, units, quantities and your own rates. Add a waste allowance to material items, a contingency and tax, and see totals by section. The BOQ stays in your browser and can be exported as CSV or printed.

How it works

• Each item amount is quantity times rate. For lines ticked as material items, the amount is raised by the waste percentage.
• The items subtotal adds up all amounts. Contingency is a percentage of the subtotal, and tax is a percentage of the subtotal plus contingency.
• Totals by section show how many items each section has, its amount and its share of the subtotal.
• Items without a rate count as zero and are named in a note, so they are not forgotten.

This is a preliminary estimate for planning and shopping lists. It is not a structural design, a safety check or a building-code approval. Ask a qualified professional before you build.

Common questions

Where do the rates come from?

From you: recent supplier or contractor quotes, or your own past jobs. The tool has no built-in rates, because prices change by place and over time.

Which items should get the waste allowance?

Tick materials that are cut, mixed or broken on site, such as blocks, tiles or concrete, and leave labour-only items unticked. Choose the percentage from your own experience or your supplier's advice.

Is this the same as a professional BOQ?

No. It is a basic list for planning and comparing quotes. A quantity surveyor's BOQ follows a set method of measurement and is checked against the drawings.
