Bill of Quantities

BOQ Full Form in English, letter by letter

BOQ is the Bill of Quantities, an itemised list of measured work and materials that contractors price when bidding for a construction tender.

BOQ Full Form in Indian Languages

Open a PWD or NHAI tender and the pages that decide the price are the BOQ, the Bill of Quantities. Here is the name in six Indian languages.

What sits inside a Bill of Quantities

A Bill of Quantities (BOQ) is an itemised list of the work, materials, labour and equipment a construction project needs. The client's consultant prepares it from the drawings and the specification. Each line gives a description, a unit of measurement such as square metre, cubic metre or kilogram, and a quantity.

It is normally arranged in sections: preliminaries and site establishment, the main structure, finishes, services such as electrical and plumbing, and external works. The consultant measures the quantities. The rate and amount columns are left blank for bidders to fill.

How the BOQ drives the tender

Each contractor quotes a rate against every item, and the quantities multiply out to a total bid. Because every bidder prices exactly the same quantities, the bids can be compared line by line. That is the whole purpose of the document.

The BOQ keeps working after the award. Work is measured on site and paid at the quoted rates, and a change in scope is priced with the same rates unless the change needs a fresh rate. Provisional sums cover items that are not yet defined, and daywork rates cover small jobs paid by the hour or day.

Contractors read the BOQ for what it leaves out as much as for what it contains. Notes at the start of each section often say what the rate must include, such as scaffolding, curing or lead and lift of materials, and a rate quoted without reading them can turn into a loss.

A small worked example

Suppose a school boundary wall tender lists 120 cubic metres of brick masonry in cement mortar. One bidder quotes 6,500 rupees per cubic metre and another quotes 6,200. The amounts are 7,80,000 and 7,44,000 rupees. These figures are only for illustration, but the method is real: quantity multiplied by rate, line after line, then added up with taxes and any percentage the tender document asks for.

If the engineer later orders the wall to be built 10 metres longer, the extra masonry is measured and paid at the same quoted rate. If the work involves an item that is not in the BOQ at all, a new rate is agreed, usually by analysing the cost of labour, materials and machinery.

BOQ practice in Indian government tenders

State PWDs, NHAI, municipal bodies and central public works departments publish tenders with BOQs on e-procurement portals. Bidders often quote a percentage above or below the department's Schedule of Rates, such as the CPWD Delhi Schedule of Rates, instead of building every rate from scratch. The department's own estimate is prepared from the same rate book.

Quantities are generally measured as per the Bureau of Indian Standards code IS 1200, which lays down the methods of measurement for building and civil engineering work. Tenders for roads, bridges and canals follow the measurement rules in their own specifications.

Some tenders are item-rate, where each BOQ line is priced, and others are percentage-rate, where one overall percentage is quoted over the department's estimate. Lump-sum contracts price the whole job against drawings with no itemised quantities. Read the tender notice to see which type applies.

BOQ versus the documents around it

A Schedule of Rates is a price list with no project quantities. An estimate is the client's own projection of cost made before tendering. The measurement book is the PWD's on-site record of work actually executed, used for bill payments and audit. The BOQ sits between these as the priced contract document.

Tenderers and clients both watch for unbalanced bidding, which means a very high rate on work done early and a very low rate on work done later. It distorts payments and signals risk, and consultants usually check for it before accepting the lowest total.

Who prepares a BOQ, and why the skill pays

Quantity surveyors and civil engineers prepare BOQs from drawing sets, spreadsheets and estimating software, checking each measurement against the latest drawing revision. A missing item or a wrong unit can move a bid by lakhs of rupees.

Estimation and costing is a core subject in civil engineering diplomas and degrees, and it features in exams such as SSC JE and RRB JE. Students who can read and prepare a BOQ before they reach a site office are a step ahead of those who learn it on the job.

Before bidding on any tender, read the BOQ notes and the units line by line and compare the quantities with the drawings. Most disputes after the award start with an item that was priced without reading what the rate was meant to include.
