Quantity surveyors quote BOQ preparation fees in three different ways, and which one a client encounters often just comes down to firm preference rather than project type. Understanding all three helps you compare quotes on equal footing.
Three Fee Structures Compared
| Model | How It’s Calculated | Example (2,000 sq ft, ₹40L project) |
|---|---|---|
| Per sq ft | Built-up area × rate | 2,000 × ₹5 = ₹10,000 |
| Percentage of cost | Estimated project cost × % | ₹40,00,000 × 1% = ₹40,000 |
| Lump sum | Fixed quote based on scope discussion | ₹15,000-₹25,000 (negotiated) |
Notice how differently these land on the same project — percentage-of-cost fees can run several times higher than per-sq-ft fees on a high-spec build, since the fee scales with finish quality, not just area.
Which Model Should You Ask For?
- Standard residential/commercial project — per sq ft is usually most predictable and easiest to compare across quotes.
- High-spec or luxury project — watch out for percentage-of-cost quotes, since they scale with finish cost, not BOQ effort.
- Small, well-defined scope — lump sum gives cost certainty upfront with no surprises.

Frequently Asked Questions
What is the most common BOQ preparation fee structure in India?
Per square foot is most common for residential and small commercial projects; percentage-of-cost is more common for larger or high-spec projects.
Is percentage-of-cost fee negotiable?
Yes — percentage rates (typically 0.5-2%) are usually negotiable, especially for larger projects where the absolute fee becomes significant.
Can I switch between fee models when getting quotes?
Ask each quantity surveyor to quote in the same model (or convert their quote to a per-sq-ft equivalent) so you can compare fairly.
