How to Read Your Contractor's BOQ — Line by Line

Last updated July 2026 · 12 min read · By Ghar Ka Budget Editorial Team

If your contractor handed you a single number — "₹38 lakh for civil work, sir" — and you signed it, you're going to be charged extra for things you assumed were included. Here's the document that prevents that, and how to actually read it.

TL;DR A BOQ (Bill of Quantities) is the line-item breakdown of every construction activity, with rates and quantities. Demand one before signing. This article walks through a sample BOQ for a 2,000 sqft house line-by-line, flagging the items contractors most often inflate, miss, or hide.

What a BOQ actually is

A Bill of Quantities is a structured document with five columns: item description, unit of measurement, quantity, rate per unit, and total amount. Every construction activity gets its own row. A complete BOQ for a 2,000 sqft independent house should run 80–150 line items grouped into 12–18 sections.

This isn't optional paperwork. The BOQ is the document you'll use to:

Indicative numbers for a Standard quality 2,000 sqft house in Pune outskirts (May 2026). Your contractor's BOQ will look similar in structure.

Section 1 (excavation): the easy stuff

Excavation rates are commodity-priced. Cross-check with the CPWD SoR (Item No. 2.4 series in the standard schedule) — your contractor should be within 10–15% of CPWD rates. Anti-termite treatment is the most commonly forgotten item — make sure it appears, separately, with a per-sqm rate.

Sections 2–4 (RCC work): the most expensive, most often padded

Items 2.2 and 4.1 each say "including 1% steel reinforcement." This phrasing is the most common point of dispute. Always insist that steel reinforcement be a separate, explicit line item — by weight (kg) and grade (Fe500 / Fe550) — not "included" in concrete rate. When it's hidden inside concrete rates, the contractor has flexibility to substitute lower-grade or less steel later, with no audit trail.

Reinforcement steel for a 2,000 sqft house is typically 4,500–6,000 kg. At ₹68–82/kg in May 2026, this alone is ₹3–5 lakh. Hidden inside concrete rates, you can't audit it.

Red flag — line 4.3 in our sample: "Reinforcement steel — extra over Fe500 included above" with no rate. This is deliberately vague. Force the contractor to: (a) declare total steel weight and grade, (b) split it into footing, columns, slab, lintels separately, (c) attach a steel bar bending schedule (BBS) from the structural engineer.

Section 5 (brick & plaster): watch the brick class

Item 5.1 says "Class A bricks." Verify on site — many contractors substitute Class B or C bricks (₹2–3 cheaper per piece, but 30–40% lower compressive strength). At ~1,200 bricks per cum and 22 cum of wall, the contractor's saving from substitution is ₹50,000–70,000 — and you don't notice until 5 years later when walls develop cracks.

Plaster thickness: external should be 20mm double-coat, internal 12mm single-coat. Anything thinner is sub-standard.

Section 6 (flooring): tile material vs labour split

The line item "vitrified tile — material rate ₹65/sqft, laying ₹35/sqft" is good — it shows the breakdown. If your BOQ shows just a flat "₹100/sqft for tiling work," demand the split. Contractor markup on tile is the single largest source of overcharging in interiors. Buy tiles yourself from the dealer (Kajaria, Somany, Orient Bell) — saves 15–25%.

Section 7 (doors & windows): teakwood vs other

The main door line says "teakwood frame + flush shutter — ₹28,000." Watch out: "teakwood" can mean Burma teak (genuine, ₹4,500/cft) or African Sapele (look-alike, ₹2,200/cft) or Ghana teak (cheaper still). Specify the teak species in writing. Same for flush shutters: BWR-grade plywood (boiling water resistant) vs IS:303-grade — substantial difference in monsoon performance.

Section 8 (plumbing): the "lump sum" trap

Item 8.1 — "Plumbing rough-in — LS — ₹95,000" — is the worst kind of line item. "LS" (lump sum) means the contractor gets to define what's included. Disputes always end with "that's not included in my LS." Force the contractor to break this into specific items: number of CPVC concealed lines, number of fittings, taps, drainage points, water heater provision, with brand and spec for each. This may double the line count but eliminates 80% of mid-project surprise costs.

Section 9 (electrical): per-point or LS?

"Electrical rough-in" charged per point (item 9.1) is good. A "point" = one switch, socket, or fixture. A 2,000 sqft house typically needs 65–80 points. ₹680/point is standard for concealed wiring with PVC conduit. If your BOQ says "electrical work LS ₹X" with no point count, it's unauditable.

Branded modular switches are usually quoted as a separate LS (item 9.2 here). "Anchor / Havells / Legrand" all have a 6× spread in price within their own ranges. Get the contractor to specify the exact series (e.g., "Anchor Roma Classic" or "Havells Crabtree Athena") — without that, you'll get the cheapest variant.

Section 10 (painting): coat count is everything

Always insist on "putty + primer + 2 coats emulsion" in writing. Single-coat is the most common contractor short-cut and looks visibly streaky in 2–3 months. Specify the paint product line: not just "Asian Paints" but "Asian Paints Tractor Emulsion" (basic) or "Royale" (premium) — the same brand has a 5× price spread.

Section 11 (waterproofing): get the membrane spec

"Brickbat coba" is the traditional terrace waterproofing method (item 11.1). Modern alternatives include APP membrane (₹120–180/sqft), polyurethane coatings (₹80–120/sqft), and crystalline waterproofing (₹250+/sqft). Specify which method, brand, and warranty — most premium products carry 7–10 year warranty when professionally applied.

Section 12 (sundries): the items contractors often "forget"

Item 12.1 (scaffolding) saying "included in items above" is a major red flag. Scaffolding for a G+1 house typically costs ₹40,000–80,000 in pipe scaffolding rental + erection labour. If it's not a separate line item, the contractor will likely charge it as "extra" mid-project, claiming it wasn't in your scope.

Other items contractors routinely omit and then bill separately:

Insist that each of these appears as a separate line item, even if the rate is ₹0 or "included." That way, when a dispute arises, you can point to the line.

Cross-checking BOQ rates: three sources

For any BOQ rate that looks high, cross-check against:

SourceWhat it gives youHow accurate vs market
CPWD Schedule of Rates (SoR)Government benchmark for every construction line item, India-wideTypically 10–20% below market
State PWD ratesState-specific benchmark; slightly more current than CPWDWithin 5–10% of market
Hardware shop quoteDirect material price (cement, steel, tile, paint)Bang on. Use for material lines only.

The CPWD SoR is publicly downloadable as a PDF — search "CPWD Schedule of Rates 2026" on your search engine. State PWD SoRs are on each state PWD website.

Comparing 3 contractor BOQs: what matters

Don't compare on totals. Compare line-by-line. A contractor whose grand total is ₹1.5 lakh higher might actually be cheaper if they include scaffolding, BBS, and curing that the other two are quietly leaving out. Build a side-by-side spreadsheet:

Outliers go both ways. A contractor 30% below median on PCC rate is not necessarily "cheaper" — they might be using cement grade lower than what they wrote, or sand of lower quality. Below-market rates are equally suspicious as above-market ones.

The one BOQ payment-schedule clause every owner should add

In your contract, link milestone payments to BOQ completion — not to dates. Specifically:

Final 5% is held for 90 days post-handover to address any defects (this is called the "defect liability period" payment). Do not pay this until you've gone through one full monsoon and verified no leaks.

Frequently asked questions

My contractor refuses to give a BOQ. What now?
Walk away. A contractor who can't produce a BOQ either doesn't have the operational discipline to run a project predictably, or doesn't want you to audit their margins. Both are dealbreakers. Find a contractor who works with BOQs as standard. Established contractors with engineering backgrounds always have BOQs ready; informal "contact thekedar" contractors usually don't.
Do I pay extra to get a BOQ prepared?
Sometimes. Some contractors charge ₹5,000–15,000 to prepare a detailed BOQ before signing — and adjust this against the final bill if you proceed with them. This is reasonable; preparing a real BOQ takes 8–15 hours of an engineer's time. What's NOT reasonable: charging for the BOQ and then refusing to share line-item rates "because that's our internal pricing." If you've paid for the BOQ, you own the document.
Can I prepare the BOQ myself and get contractors to fill in rates?
Yes — and this is actually best practice. Hire a consulting civil engineer for ₹15,000–35,000 to prepare a quantity take-off from your architect's drawings, then send the BOQ template to 3+ contractors for rate-only quotes. This guarantees apples-to-apples comparison. CPWD publishes a standard BOQ template you can adapt; many architects also provide BOQ templates as part of their full service.
What's the difference between BOQ and BoM?
A Bill of Materials (BoM) lists only materials and quantities — no labour, no rates. It's a procurement document. A BOQ includes both materials and labour, with rates and totals. It's a contracting document. For your home construction, you want a BOQ. A BoM alone leaves all labour costs negotiable.
Is GST included in BOQ rates?
It depends on whether the contractor is registered under GST. If your annual project value is above ₹20 lakh and the contractor is GST-registered, they'll quote rates excluding GST and add 18% on top (some construction services are 12% under composition; verify with your contractor's tax consultant). For smaller projects or unregistered contractors, GST doesn't apply — but neither will they give you proper invoices, which can complicate any future home loan or property registration. Always verify GST treatment in writing before signing.
