How to Read a BOQ Before You Sign a Construction Contract

Most people building a house sign the biggest financial document of their lives after reading it for twenty minutes. The Bill of Quantities, or BOQ, is that document. When you compare contractors in Mysuru, the BOQ is where the real comparison happens, because two quotations with the same headline rate can describe two very different houses.

The good news is that you do not need an engineering degree to read one. You need to know what each column means, where the gaps usually hide, and which questions to ask before you sign. If you are still shortlisting builders, our other guides on choosing and comparing contractors in Mysuru cover that earlier stage. This article assumes you have a BOQ in hand and a pen ready.

What a BOQ actually is, and what it is not

A BOQ is an itemised schedule of the work to be done. A typical line reads: RCC for footings, M20 grade, 18 cubic metres, at a stated rate per cubic metre, giving a line amount. Add up every line and you get the contract value.

What a BOQ is not is a specification. The BOQ tells you how much concrete; the specification tells you what cement brand, what steel grade and what tile range. A BOQ without a written specification behind it is only half a document. At Uniq Builders every package is built to a written specification shared during consultation, so the two can be read side by side. Ask any builder for both.

The third leg is the drawings. Quantities are calculated from drawings, so if the drawings are incomplete, the quantities are guesses. A builder who prepares working drawings for all floors before pricing, as our architectural design service does, is quoting from measurement rather than estimation.

The four columns, and what to check in each

Every BOQ line has four parts, and each has its own failure mode.

• Description. The most important column and the most abused. “Flooring, per sq ft” tells you nothing. A proper description names the material class, the grade or thickness, and the method. Vague descriptions become disputes later.
• Quantity. Check that quantities roughly match your plan. If your built-up area is 1,600 sq ft but the flooring line says 2,400 sq ft with no explanation, ask why.
• Unit and rate. Confirm the unit fits the item: concrete per cubic metre, plastering per square metre, doors per number.
• Amount. Multiply a few lines yourself. Arithmetic errors are common, and binding once you sign.

Then read what sits around the columns: the notes, exclusions and assumptions in small print at the end. This is where a low quotation earns its lowness.

Where the gaps usually hide

The same omissions appear again and again. Before signing, check whether these items are inside the price, priced separately, or missing entirely.

1. Government approvals and connections. Plan sanction, khata work, power, water and sewage connections take time and follow-up, yet many BOQs are silent on them. In every Uniq Builders package these approvals are handled by the company, with free assistance for licensing work; statutory fees are paid directly by the client, so no markup hides inside them.
2. Soil test and structural design. Structural design without a soil test is guesswork. Confirm both are expressly included.
3. Site conditions. Rock excavation, extra foundation depth and imported filling earth depend on your plot. No honest builder can price them without seeing the land, which is why we quote them separately after a free site visit. A BOQ that claims to include them sight unseen is either padded or planning a variation claim.
4. The “provisional sum” trap. Items marked provisional or “at actuals” are placeholders, not prices. A few are legitimate; a BOQ full of them is not a fixed price at all.
5. Warranty and after-handover service. If it is not written down, it does not exist. Look for a stated workmanship warranty and a service period, the way our packages include a workmanship warranty and one year of free service after handover.

Link the BOQ to the payment schedule

A BOQ tells you what you are paying for; the payment schedule tells you when. Read them together. Each payment stage should map to completed, verifiable work: foundation done, slab cast, plastering finished. Be wary of front-loaded schedules where most of the money is due before most of the work exists. Your leverage as a client is the unpaid balance, and a good schedule keeps it roughly proportional to the work remaining.

Also confirm how variations are handled. If you change a tile or add a room mid-build, the contract should say how the new rate is derived, ideally from the BOQ rates already agreed, so a change does not become a renegotiation.

Finally, anchor everything to a rate basis you understand. Our construction packages start at ₹1,999 per sq ft for Premium, ₹2,499 for Gold with complimentary interiors, and ₹2,999 for Platinum, with the final figure confirmed after a free site visit; terms and conditions apply. Whoever you build with, insist on that structure: a starting rate, a written specification, and a final figure fixed only after the site has been seen.

A ten-minute checklist before you sign

With the BOQ in front of you, check:

• Do the BOQ, the written specification and the drawings all exist, and do they agree with each other?
• Is every description specific enough that a stranger could price it?
• Do quantities broadly match your plan area?
• Are approvals, soil test, warranty and service period written in?
• Are provisional sums few and clearly flagged?
• Does each payment stage correspond to verifiable completed work?
• Is the variation procedure defined?

If any answer is no, ask for the document to be corrected before signing, not after. A professional builder will not flinch at the questions. Uniq Builders has been building since 2009 across Mysuru and five other cities, and we are happy to walk you through our own BOQ line by line. Book a free site visit and consultation, bring any quotation you already have, and we will help you read it honestly.

Frequently asked questions

Is a BOQ legally binding once I sign the contract?

Yes, once annexed to a signed contract, its descriptions, quantities and rates define what the builder must deliver and what you must pay. That is why vague lines are dangerous. Get every unclear line rewritten before signing.

What is the difference between a BOQ and a square-foot package rate?

A package rate is a pricing summary; the BOQ and written specification behind it define what the rate buys. A good builder gives you both, with the final figure confirmed after a site visit since conditions like rock or extra foundation depth vary by plot. Judge the specification, not just the headline number.

Can I ask a builder to revise their BOQ before signing?

You can and you should. Reasonable requests include tightening vague descriptions, adding brand or grade names from the specification, correcting quantities and converting provisional sums into firm prices. A professional builder treats this as normal due diligence, and reluctance to answer is itself useful information.
