BOQ Full Form (Bill of Quantities)

BOQ stands for Bill of Quantities — a tabulated document that lists every item of work in a project, with its quantity, unit, rate and amount. It is the backbone of tendering, cost control and billing: contractors quote against it, and running bills are checked against it.
What a BOQ contains
For every item of work, a BOQ line gives:
| Column | Meaning |
|---|---|
| Description | The work item (e.g. "M20 RCC in columns") |
| Unit | How it is measured (m³, m², kg, running m) |
| Quantity | The measured quantity |
| Rate | Cost per unit |
| Amount | Quantity × Rate |
The quantities are measured to a standard method — IS 1200 — so that everyone computes and deducts them the same way, and the totals can be checked rather than argued.
Why a BOQ matters
- Tendering: contractors fill in their rates against the same item list, so bids are comparable.
- Cost control: the priced BOQ is the budget; deviations show up against it.
- Billing & reconciliation: running bills are measured against the BOQ, and materials issued are reconciled against what the measured work should have consumed.
For a house, a BOQ is what turns a rough per-sq-ft figure into an item-by-item budget you can hold a contractor to — the same idea as our material bill and cost breakup, formalised.
Frequently asked questions
What is the full form of BOQ? Bill of Quantities — an itemised list of every work item with its quantity, unit, rate and amount.
What is the purpose of a BOQ? It lets contractors bid against the same item list, sets the project budget, and provides the basis for measuring running bills and reconciling materials.
How is a BOQ prepared? By measuring quantities from the drawings to a standard method (IS 1200 in India), then pricing each item with a rate to get the amount.
What is the difference between a BOQ and an estimate? An estimate is an approximate total cost; a BOQ is the detailed, item-wise breakdown of quantities and rates that the estimate and the bills are built on.
