A Bill of Quantities (BOQ) is an itemised schedule listing every material, quantity, unit rate, and labour task in a construction project. In Pakistan, a detailed BOQ protects homeowners by fixing scope, exposing hidden costs, preventing mid-project price hikes, and giving you a measurable basis for payments and variations.
This guide explains what a proper construction BOQ looks like in the Islamabad and Rawalpindi market, the specific risks it removes, how it compares to lump-sum and per-sqft contracts, and the red flags to reject before you sign anything.
What a Bill of Quantities Actually Contains
This section defines a BOQ in plain language and lists the standard columns and sections you should see in any Pakistani construction document. A BOQ is not a sales quote — it is a measured schedule, derived from the architectural and structural drawings, that every line of the contract sum can be traced back to.
A standard residential BOQ uses five columns: item description, unit, quantity, unit rate (PKR), and amount. Units follow site conventions — cft for concrete and excavation, sft for plaster and tiles, rft for skirting and pipes, kg for steel, and “number” for doors, windows and fixtures.
Items are grouped into sections that follow the order of construction, in line with Composite Schedule of Rates conventions used by Pakistani quantity surveyors:
- Earthwork and foundation
- RCC (columns, beams, slabs)
- Brickwork and blockwork
- Plaster and finishes
- Flooring and tiles
- Doors and windows
- Electrical conduiting and fixtures
- Plumbing and sanitary
- Paint and external finishes
Compare this to a lump-sum quote — for example, “10 Marla grey structure at Rs. 3,400 per sqft” or “complete house with standard finishing at Rs. 7,500 per sqft.” The per-sqft model is useful for early budgeting, and at DevPro’s house construction service we publish three transparent tiers — Rs. 7,500 per sqft (Standard), Rs. 8,800 per sqft (Premium), and Rs. 10,600 per sqft (Luxury) — but the BOQ is what makes those numbers enforceable on site.
Why a Detailed BOQ Protects You — Five Real Risks It Removes
Homeowners without a BOQ usually lose money in five predictable ways. Each one maps directly to a clause or line item in a properly drafted document.
- Scope creep. A vague quote that says “complete bathroom” lets the contractor argue later that the second mirror, the towel rail, or the geyser connection was “extra.” A BOQ lists each fixture by name and quantity, so the scope is closed before work starts.
- Material downgrade. Without a brand and grade locked in writing, a “standard tile” can become any tile in the market. A proper BOQ specifies steel grade (Grade 60 deformed bars), cement brand (e.g. DG, Bestway, Lucky), brick class (first-class machine-made), and tile origin (local vs imported).
- Quantity inflation. Steel and concrete quantities should come from a take-off sheet against the structural drawings — not from a thumb-rule estimate. A measurable BOQ lets you re-check on site that the kgs of steel actually delivered match the kgs being billed.
- Mid-project rate hikes. When cement or sariya prices move during the build, an undisciplined contractor asks for a top-up. A BOQ with fixed unit rates for the project duration removes this conversation; only quantities can be re-measured, not the rate.
- Payment disputes. Without measured work, payment milestones become arguments. A BOQ-based contract ties each tranche to a specific deliverable — DPC level, slab cast, plaster complete — so both sides know exactly what triggers the next payment.
BOQ vs Lump-Sum vs Turnkey Contracts in Pakistan
This section compares the three contract types Pakistani contractors typically offer and shows where BOQ-based agreements sit. The right format depends on how much certainty you need on scope and how much risk you are willing to carry on quantities.
| Contract type | How priced | Risk to owner | Best for |
|---|---|---|---|
| BOQ-based | Each item priced by unit rate × measured quantity | Lowest — every rupee is traceable | Custom houses, commercial, institutional |
| Lump-sum | One fixed total against a defined scope | Medium — disputes start when scope is unclear | Tight scopes with detailed drawings |
| Turnkey / per-sqft | One rate per covered sqft (e.g. Rs. 7,500–10,600 per sqft) | Medium-high — depends on tier definition | Standardised builds, early budgeting |
Per-sqft contracts are perfectly workable when the tier is properly defined. Our published rates — Rs. 7,500 per sqft (Grey + Standard B), Rs. 8,800 per sqft (Grey + Premium A), and Rs. 10,600 per sqft (Grey + Luxury A+) — are backed by a BOQ that lists exactly what each tier delivers. Use the 2026 cost calculator for Islamabad and Rawalpindi for a tier-based ballpark, then ask for the BOQ behind it before you commit.
How to Read a Construction BOQ — A Line-by-Line Walkthrough
This section takes a single residential BOQ line and explains every field so a non-technical client can audit their own document. Once you can read one line, you can read all of them.
A typical RCC slab line reads like this:
RCC 1:2:4 in roof slab, including shuttering, cutting, bending and binding of steel — Unit: cft — Qty: 1,250 — Rate: [unit rate from contractor] — Amount: [Qty × Rate]
Here is what each field tells you:
- Item description. Mix ratio (1:2:4 is one part cement, two parts sand, four parts crush), location (roof slab), and what is included in the rate (shuttering, steel bending and binding).
- Unit. Concrete is billed in cubic feet (cft) in most Pakistani BOQs. Plaster and flooring are in sft. Steel is separated and billed in kg.
- Quantity. Should come from the structural drawings, not a thumb-rule. Ask for the take-off sheet.
- Unit rate. Should be locked for the project duration. If escalation is allowed, the clause must say so explicitly.
- Amount. Quantity × rate. The sum of all amounts should match the contract total to the rupee.
The grey-structure portion of a residential BOQ should include foundation, columns and beams, brick walls, roof slab, underground water tank, and basic plumbing and electrical conduiting — exactly the scope our grey rate of Rs. 3,400 per sqft is built around. Items commonly missing from weak BOQs: steel grade, cement brand, brick class, tile origin, and sanitary brand. If any of those are absent, the document is not protecting you.
What a Good BOQ Looks Like for a 10 Marla House in Islamabad
This section gives a concrete picture of BOQ size and structure for a typical Islamabad or Rawalpindi build. A 10 Marla house has roughly 3,400 sqft of covered area (double-storey), which at the Standard tier of Rs. 7,500 per sqft works out to an indicative total around Rs. 2.55 Cr, with the calculator’s ±8% spread giving a realistic range. See the house construction cost breakdown for 2026 for the full per-tier math.
A residential BOQ at this scale typically contains:
- A grey-structure section covering foundation, columns and beams, brick walls, roof slab, underground water tank, basic plumbing and electrical conduiting
- A finishing section covering flooring and tiles, plaster and paint, woodwork and kitchen, doors and windows, sanitary and bathroom fixtures, electrical fixtures and fittings
- A separate steel schedule in kg, broken down by member
- A door and window schedule with sizes, frame type and shutter material
- A sanitary schedule listing brand and model for WCs, basins, taps and showers
- A summary page where all sections roll up to the contract total
Real-world examples from our completed work — the Mediterranean Villas and Georgian Villas at Capital Smart City, both 10 Marla double-storey, 5-bedroom luxury builds — used BOQs structured exactly this way, with grey and finishing scope priced separately so the client could see where every rupee landed.
Red Flags in a BOQ — What to Reject Before Signing
A weak BOQ is sometimes worse than no BOQ, because it dresses up a loose scope in formal-looking columns. Reject any document showing the following:
- Vague descriptions like “internal works” or “as per site requirement”
- Missing brand and grade for steel, cement, bricks, tiles or sanitary
- No unit specified (just “1 lot” or “complete”)
- Lump-sum lines hidden inside an otherwise itemised BOQ
- No variation order clause explaining how additions and deletions are priced
- No escalation clause (or, conversely, an open-ended escalation clause)
- No reference to the architectural and structural drawing numbers
- A contract total that does not match the line-item sum
- No signature, company stamp or dated page numbers
- No payment milestone schedule tied to measured work

How DevPro Prepares Your BOQ
This section explains DevPro’s BOQ process so you know what to expect when requesting a quote. We follow the same five steps on every residential project:
- Drawings reviewed. Architectural and structural drawings are reviewed together so quantities reconcile across both sets.
- Quantities taken off drawings, not estimated. Concrete, steel, brickwork, plaster and flooring are calculated from drawings — not back-calculated from a sqft rate.
- Material brands proposed in three tiers. B (Standard), A (Premium) and A+ (Luxury) options for cement, steel, tiles, sanitary, electrical and woodwork — so you can mix tiers across sections if you want to.
- Rates locked for project duration. Unit rates are fixed; quantities are re-measured against actual work.
- Payment milestones tied to measurable progress. Each tranche is released against a defined site stage, not a calendar date.
We are PEC-registered (C5/E 29168), DHA-registered (6684, Category C-5) and FWO-enlisted (T-5491), with 10+ years of experience and 50+ projects delivered across Islamabad and Rawalpindi. You can request a free BOQ from DevPro once your architectural drawings are ready — typically returned within a working week.
BOQ for Commercial and Institutional Projects
Commercial and institutional BOQs follow the same logic as residential but add several specialised sections that change the document length and structure significantly. Expect dedicated chapters for fire alarm and firefighting systems, networking and structured cabling, CCTV, public address (PA) systems, HVAC, and façade works — each with its own units, brands and testing-and-commissioning lines.
Our completed Forces School Boys Campus in Blue World City (46,000 sft) used a BOQ that combined civil works with fire alarm, firefighting, networking, CCTV and PA systems under a single contract. The ongoing Forces School Girls Campus (4-storey frame structure, 11,500 sft), Sector Shops Mini Commercial (4-storey, 10,500 sft), and Blue Square Commercial Shops (21 dealer shops) follow the same multi-section BOQ structure. Even pure infrastructure work — like our DHA Islamabad project with 40 manholes and 2,876 ft of 9-inch RCC pipeline — is priced item-by-item against measured quantities. See our commercial construction services page and completed and ongoing DevPro projects for the full portfolio.
Frequently Asked Questions
What is BOQ in construction in Pakistan?
A BOQ, or Bill of Quantities, is an itemised schedule listing every material, labour task, unit, quantity and unit rate in a construction project. In Pakistan, it is the document contractors and quantity surveyors use to price work against architectural and structural drawings, and it becomes the measurable basis of the construction contract once signed.
Who prepares the Bill of Quantities — the contractor or the client?
The BOQ is typically prepared by the contractor’s quantity surveyor or an independent QS hired by the client, working from the architect’s and structural engineer’s drawings. The client then reviews it, negotiates rates and inclusions, and signs it as part of the contract. On larger projects, owners often hire a separate third-party QS to verify quantities.
What is the difference between a BOQ and an estimate?
An estimate is a single approximate figure given for early budgeting — useful for deciding whether to proceed, but not binding. A BOQ is a line-item schedule with measurable quantities and locked unit rates that becomes part of the construction contract. Estimates can swing widely; a properly drafted BOQ commits both parties to specific numbers.
How long should a residential construction BOQ be?
A 10 Marla to 1 Kanal house BOQ in Islamabad or Rawalpindi typically runs into the order of one to two hundred line items, split between grey structure, steel schedule, finishing, doors and windows, sanitary, and electrical. Shorter than that, and the document is probably grouping items into lump-sum lines that hide scope. Length depends on how granular the brand and grade specifications are.
Can a BOQ change after the contract is signed?
Quantities can change — they are re-measured against actual work executed on site, which is the normal mechanism for honest adjustment. Unit rates stay fixed for the project duration unless an escalation clause says otherwise. Any change in scope (new room, upgraded finish) goes through a written variation order priced against the BOQ’s existing unit rates.
Is a BOQ required for DHA Islamabad construction approvals?
DHA Islamabad’s construction approval process focuses on drawings, NOCs, fees and structural compliance rather than the BOQ itself, which is a private contract between owner and contractor. That said, having a detailed BOQ is essential for protecting yourself during the build. See the DHA Islamabad construction guide for the full approval checklist.
How do I verify the quantities in my contractor’s BOQ?
Ask for the take-off sheet — the working document that shows how each quantity was derived from the drawings. Cross-check headline items (concrete in cft, steel in kg, brickwork in cft, plaster in sft) against the architectural and structural sets. For projects above 10 Marla, it is worth hiring an independent quantity surveyor for a half-day review before signing.
Does DevPro provide a free BOQ?
Yes — DevPro provides a detailed BOQ on request once your architectural and structural drawings are shared, at no cost and with no obligation to proceed. The document includes itemised grey and finishing scope, brand options across our three tiers (B, A, A+), and a payment milestone schedule. Reach out via our contact page to request yours.
