If you’re planning to build a residential property in Nigeria, one of the smartest documents you can put together before you break ground is a Bill of Quantities (BOQ). In our previous guide, How to Prepare a Bill of Quantities (BOQ) in Nigeria, we walked through the full process of producing a BOQ from your architectural and structural drawings. This guide takes that one step further by giving you a practical, ready-to-adapt BOQ template for a residential building, along with a worked example you can use as a starting point for your own project.
Whether you are a first-time landlord managing a self-build, a small contractor pricing a client’s bungalow, or a young engineer preparing your first cost estimate, this template gives you a structured way to capture every item of work, material, and cost before construction starts — instead of discovering gaps in your budget halfway through the project.
What Is a Bill of Quantities Template?
A Bill of Quantities template is a standardized, reusable spreadsheet or document format that lists every measurable item of work in a building project — organized by trade or construction stage — with columns for description, unit of measurement, quantity, unit rate, and total cost. Instead of starting from a blank page for every new project, a quantity surveyor, contractor, or building owner can reuse the same structure and simply update the quantities and rates to match the specific drawing in front of them.
For residential buildings in Nigeria — bungalows, duplexes, and small blocks of flats — the template typically follows the same broad sequence construction actually happens on site: preliminaries first, then substructure (foundation), superstructure (walls and frame), roofing, finishes, and finally the mechanical and electrical installations and external works. Keeping the template in this order makes it easier to track spending against physical progress on site, which is exactly how most Nigerian contractors and clients monitor payment stages.
Why You Need a BOQ Template Before You Start Building
Many self-build projects in Nigeria run into cost overruns not because materials suddenly became expensive, but because nobody itemized the work properly before construction began. A good template solves several problems at once:
- It forces completeness. A structured template prompts you to price items that are easy to forget in a rough estimate — damp-proof membranes, lintels, rainwater goods, distribution boards — rather than just “blockwork” and “roofing” as vague lump sums.
- It standardizes contractor quotes. When you send the same BOQ format to two or three contractors or artisans, you get comparable quotes, because everyone is pricing the same quantities against the same units instead of guessing at scope.
- It supports staged payments. Because the template is broken into construction stages, it lines up naturally with payment-by-stage arrangements.
- It reduces disputes. A documented BOQ becomes the reference point if a disagreement comes up later about what was included in a contractor’s price and what was an extra.
- It speeds up material procurement. With quantities already calculated, you can request supplier quotes for cement, blocks, rebar, and roofing sheets well ahead of when they’re needed on site.
Standard Sections of a Residential BOQ Template in Nigeria
Before looking at the worked example, it helps to understand the sections a residential BOQ template is normally divided into. Most Nigerian quantity surveyors follow a structure close to this:
1. Preliminaries
Site mobilization, site clearance, hoarding/site fencing, temporary site office or store, water and electricity for construction, and contractor’s general overheads. These costs don’t attach to a specific physical element but must still be priced and paid for.
2. Substructure (Foundation Work)
Setting out, excavation to reduce levels and for foundation trenches, disposal of excavated earth, hardcore filling and compaction, blinding concrete, foundation concrete (strip or pad footings), foundation blockwork up to damp-proof course (DPC) level, and the DPC itself.
3. Superstructure (Walls and Frame)
Blockwork above DPC (typically 9-inch external walls and 6-inch internal partitions in Nigerian residential construction), lintels over openings, columns and beams where a framed structure is used, and the ground floor slab.
4. Roofing
Roof timber or steel trusses, roofing sheets (aluminum long-span, stone-coated tiles, or corrugated), fascia boards, gutters and downpipes, and roof insulation where specified.
5. Doors, Windows and Finishes
Door and window supply and installation, plastering (internal and external rendering), floor and wall tiling, ceiling (PVC or POP), and painting.
6. Electrical Installation
Wiring, conduits, distribution board and circuit breakers, sockets and switches, light fittings, and earthing.
7. Plumbing and Mechanical Installation
Water supply pipework, sanitary fittings (WC, wash hand basin, shower), soak-away and septic tank, overhead tank and plumbing accessories.
8. External Works
Compound fence walling, gate, external drainage, paving or interlocking stones, and landscaping allowances.
A well-organized template keeps each of these as its own labeled section in the spreadsheet, with a subtotal at the end of each section and a grand total at the bottom that sums every section together — plus a contingency line, typically 5–10% of the subtotal, to absorb minor price fluctuations during construction.
Sample Bill of Quantities Template for a 3-Bedroom Bungalow
Below is a simplified version of what a residential BOQ template looks like in practice, using a standard 3-bedroom bungalow as the reference project. The “Rate” and “Amount” columns are intentionally left blank — you fill these in with current local prices from your area, since material and labor costs vary significantly between states and even between towns in Nigeria.

How to Adapt This Template to Your Own Building Plan
A template only becomes useful once you customize it to your actual drawing and location. Follow this sequence:
- Start from the approved drawing, not memory. Every quantity in the template above should be recalculated from your architectural and structural drawings — wall lengths, floor areas, and opening sizes are specific to your design.
- Adjust the sections to match your building type. A duplex will need an extra floor slab, staircase, and additional structural items (columns, beams, upper floor blockwork) that a bungalow template won’t include.
- Source current local rates. Get at least two to three supplier and artisan quotes in your specific location — Lagos, Abuja, Port Harcourt, and smaller towns can have significantly different material and labor rates.
- Separate materials from labor where possible. Some contractors prefer combined rates; others price materials and labor separately. Decide this upfront and be consistent across the whole document.
- Add a contingency line. Cement, steel, and roofing sheet prices can move within a single project timeline. A 5–10% contingency protects your budget from these swings.
- Have it reviewed. Even a well-built template benefits from a second pair of eyes — ideally a registered quantity surveyor or civil engineer — before you use it to negotiate with contractors.
Common Mistakes to Avoid When Using a BOQ Template
- Copying quantities directly from another project. Two “3-bedroom bungalows” can differ significantly in wall length, opening sizes, and finishes. Always recalculate from your own drawing.
- Leaving out preliminaries and contingency. These are easy to skip in a rough template but can add 10–15% to your true project cost if ignored.
- Mixing units inconsistently. If blockwork is measured in m² in one section and per block elsewhere, contractors will price it inconsistently and you’ll struggle to compare quotes.
- Using outdated rates. Material prices in Nigeria can shift within months. A template with rates from a previous project can badly understate your current budget.
- Treating the BOQ as fixed once written. Site conditions — such as unexpectedly poor soil requiring deeper foundations — can change quantities. The BOQ should be a living document during construction, not a one-time exercise.
Template vs a Custom BOQ from a Quantity Surveyor: Which Do You Need?
A generic template like the one above is genuinely useful for early budgeting, comparing rough contractor quotes, and understanding what a residential BOQ should contain. However, it has limits. Here’s how to decide which approach fits your situation:
| Situation | Best Approach |
|---|---|
| Early-stage budgeting before drawings are finalized | Generic template, adjusted for building size |
| Comparing rough quotes from multiple artisans | Generic template with locally sourced rates |
| Applying for a construction loan or mortgage | Custom BOQ prepared by a registered quantity surveyor |
| Complex design (split levels, large spans, non-standard structure) | Custom BOQ from a quantity surveyor/structural engineer |
| Formal contract with a building contractor | Custom BOQ tied to the actual approved drawing |
If your project is moving from the planning stage into an actual contract with a builder, it’s worth reading our companion guide, How to Prepare a Bill of Quantities in Nigeria, which explains the full measurement and take-off process a quantity surveyor follows to turn your drawing into a fully priced BOQ.
Getting a Professional BOQ Prepared for Your Project
A template gets you organized, but nothing replaces a BOQ that has been properly measured against your specific drawing by someone qualified to do it. At StructoTag, we help residential clients across Nigeria turn approved architectural and structural drawings into accurate, contractor-ready Bills of Quantities — with realistic, location-specific rates and a structure that supports staged payments and clean contractor negotiations. If you’d rather not build your BOQ from scratch, or you want a second opinion on one you’ve already prepared, that’s exactly the kind of engagement we take on.
Frequently Asked Questions
Can I use this template for any type of residential building?
The structure (preliminaries, substructure, superstructure, roofing, finishes, MEP, external works) applies broadly, but the quantities must be recalculated for your specific building. A duplex, for example, needs additional sections for upper floor slabs, staircases, and extra structural framing that a single-storey bungalow template won’t include.
Where do I get accurate rates to fill into the template?
Get quotes directly from material suppliers and artisans in your specific location, and cross-check against recent projects of similar scope nearby. Rates in Lagos or Abuja can differ noticeably from rates in smaller towns, so avoid using rates from an unrelated location or an old project.
Is a BOQ template a legal requirement for building in Nigeria?
No — a BOQ is not a statutory requirement for building approval in the way that architectural and structural drawings are. It is, however, standard professional practice for cost control, and lenders or investors will often ask for one before releasing construction funds.
How much does it cost to have a professional BOQ prepared?
This varies with project size and complexity, and is usually charged as a percentage of estimated project cost or as a flat professional fee. Our guide on how to prepare a BOQ in Nigeria covers this in more detail, or you can reach out to us directly for a quote specific to your project.
Should I give the same BOQ to every contractor I’m getting quotes from?
Yes — using the same BOQ (same quantities, same units, same scope) for every contractor you’re comparing is the only way to get quotes you can fairly compare side by side. If each contractor works from a different description of the job, their prices won’t mean the same thing.
A Bill of Quantities template won’t replace the judgment of a qualified quantity surveyor or civil engineer, but it gives you — as a building owner, landlord, or small contractor — a structured starting point for thinking about cost before the first block is laid. Use the sample above as a framework, recalculate the quantities against your own drawing, source current local rates, and don’t skip the contingency line. And when your project moves from rough budgeting into an actual contract with a builder, invest in having a proper, drawing-specific BOQ prepared — it’s one of the cheapest forms of insurance against cost overruns on a Nigerian building project.
