A civil BOQ collection page is arithmetic, not guesswork: quantity × rate for each line, a subtotal, and the percentage add-ons your commercial team has agreed. This tool keeps that chain transparent so the total can be traced back to every line item.

Method and assumptions

  • amount_i = quantity_i × rate_i
  • subtotal = Σ amount_i
  • after preliminaries = subtotal × (1 + preliminaries%)
  • after overhead & profit = after preliminaries × (1 + OH&P%)
  • total = after overhead & profit × (1 + contingency%)
  • Quantities and unit rates are entirely user-entered from the project's own take-off and quotations; the tool assumes no market price.
  • Preliminaries, overhead & profit and contingency percentages are applied cumulatively on the subtotal, matching standard BOQ collection-page practice.
  • A preliminary decision-support estimate: the result does not replace an approved design calculation or review by a competent authority.

Frequently asked questions

Does ALASOS supply unit rates?
No. There is no price database anywhere in the tools. Every rate is entered by you in USD from your own market data.
How are the percentage add-ons applied?
Cumulatively: preliminaries on the subtotal, overhead & profit on the result, then contingency on that — the standard collection-page sequence.
Can I consolidate several disciplines?
Yes, with the Multi-Discipline BOQ Generator, which rolls up per-discipline subtotals and applies the same add-on chain.
