The document most builders will never give you
A Bill of Quantities is the most important document in your construction project. It lists every single element every material, every system, every finish with brand names, grades, quantities, and costs attached to each item.
It is the document that makes a builder fully accountable for what they quoted. And it is the document that most Chennai builders will not give you because it removes their flexibility to substitute cheaper materials or add charges mid-project.
At LB Construction, every project begins with a complete BOQ. It is not a special arrangement or a premium add-on. It is how we work because it is what every client deserves.
BOQ vs a construction estimate the difference that costs lakhs
A construction estimate gives you a number. "Approximately ₹1.2 crore." It does not tell you what materials will be used, what brands will be specified, or what happens if prices change. It is a starting point not a commitment.
A Bill of Quantities is a contract. It specifies every material by name and grade, every quantity, every cost. It cannot be interpreted loosely because there is nothing loose about it. When you approve a BOQ, both you and the builder know exactly what is being built and what it costs.
The difference, on a typical Chennai residential project, is the difference between a final bill that matches your budget and one that is 30 to 40 percent higher than you expected.

We visit your plot and test the soil before we prepare any cost figure. The foundation type and therefore the structural cost cannot be accurately estimated without this data.
Your floor plan and specifications are confirmed. We use 3D design and VR walkthroughs to ensure you approve the design before we cost it.
A complete, line-by-line Bill of Quantities is prepared covering every category above.
We walk through the BOQ with you every line. You ask questions. We clarify. You understand exactly what you are getting and exactly what you are paying.
You approve the BOQ. This is the baseline for your project. Nothing is substituted without your written approval.
We build to the BOQ. Every material delivery is verified against the specification. If any item costs less than quoted, the saving is yours.
BOQ stands for Bill of Quantities. In construction, it is a comprehensive, itemised document listing every element that goes into a building project — with quantities, specifications, and costs for each item.
Yes. LB Construction prepares a full BOQ estimate at no charge, with no obligation to proceed. The estimate is our way of demonstrating transparency before you make any commitment.
A construction estimate is a rough cost projection — typically a rate per sqft applied to your floor area. A Bill of Quantities is a comprehensive specification of every element in your home with exact brands, grades, quantities, and costs. A BOQ is far more reliable and holds the builder to account.
Any change is handled through a formal change order — a documented agreement on what is changing, the cost impact, and your approval. Nothing changes without your sign-off.
Yes — and this is exactly what we encourage. A BOQ from us gives you a specification baseline. You can take that specification to any other builder and ask them to price the same items. This makes the comparison meaningful.
Our contract defines how material price movements are handled. Significant price changes in specified materials are communicated to you and handled through a formal change order that requires your approval before any additional cost is incurred.
No obligations. No hidden charges. Just a complete, honest cost breakdown for your project.
