BOQ for interior works: format, structure and how to automate it

What a BOQ actually is

A Bill of Quantities (BOQ) is an itemised breakdown of every piece of work in a project, with the
quantity, the unit of measurement, the rate and the resulting amount. For interior work it usually
sits between the design and the contract: the design says *what it looks like*, the BOQ says
*what it consists of and what it costs*.

It does four jobs at once, and most disputes come from forgetting that:

1. Prices the work so you can quote with a known margin
2. Defines scope so both sides agree what is and isn't included
3. Drives procurement — material quantities come from it
4. Drives billing — milestone and RA bills reference it

Standard structure for interior works

Most Indian interior BOQs follow this shape. Group by room, then by work category within the room —
this is what clients find easiest to read and approve.

Typical grouping

• Civil and false ceiling — demolition, gypsum, POP, cornices
• Carpentry and joinery — wardrobes, TV units, kitchen carcass, storage
• Finishes — laminate, veneer, paint, wallpaper, tiling
• Electrical — points, fixtures, wiring, automation
• Plumbing and sanitary — where in scope
• Furniture, loose and soft furnishing — often a separate BOQ
• Miscellaneous — transport, labour, site cleaning, contingency

Units: the most common source of dispute

Units feel trivial and cause more argument than rates do. Be explicit about which basis you use, and
state it on the BOQ itself.

• sqft on carpentry — state clearly whether it is *shutter area* or *developed area*. The

difference on a full home can be lakhs.

• rft on counters and skirting — confirm whether returns and edges are counted.
• nos for fixtures — specify make and model, or you have quoted a price against an unknown.
• Lump sum items — always attach a description of what is included, or a lump sum becomes an

open-ended obligation.

Six mistakes that cost margin

1. No version control. BOQ_final_v3_FINAL.xlsx is the industry joke because it is the industry

reality. If you cannot prove which version the client approved, you will absorb the difference.

1. Rates hard-typed per project. Without a central rate library, every BOQ re-prices from memory

and margin drifts silently between projects.

1. Exclusions left verbal. Anything you are *not* doing belongs in writing, in the BOQ.
2. No provisional sums. Items that genuinely cannot be measured yet should be stated as

provisional, not guessed and buried.

1. BOQ divorced from procurement. If material orders are typed separately, over-ordering is

invisible until the project is over.

1. No link to billing. When a milestone bill does not reference BOQ line items, every RA bill

becomes a negotiation.

How to automate it

The Excel template is not the problem — the *re-keying* is. Automation is worth it at the point where
these become true:

• You run more than about four concurrent projects
• More than one person edits a BOQ
• You bill in stages against the BOQ
• You want procurement to derive from the BOQ rather than be typed again

What a system should give you over a spreadsheet:

A note on AI-drafted BOQs

AI can produce a credible first draft from a requirement brief or a drawing, and that saves real
hours. It cannot know your rates, your exclusions or your client's history — so treat it as a
starting point that a human prices and checks, never as an output you send.

The safe pattern: AI drafts the item list and quantities, your team applies the rate library and
edits exclusions, and the versioned document goes out for approval.

Summary

A good BOQ is specific about units, explicit about exclusions, versioned, and connected to what
happens next — ordering and billing. Whether you do that in a spreadsheet or a system is a question
of scale, not sophistication. Below four concurrent projects, a disciplined spreadsheet is fine.
Above it, the re-keying costs more than the software.
