BOQ preparation of civil work is the process of converting approved drawings into a structured, priced document that lists every item of construction — quantity, unit, rate, and amount — in a format that a client, bank, or tendering authority can verify line by line. Done properly, it takes a defined sequence of steps; done casually, it becomes the single biggest source of cost disputes on a project.
This guide walks through that process end to end, with the structure a civil work BOQ actually needs and a sample table you can follow.
What Does “BOQ Preparation of Civil Work” Actually Involve?
For civil work specifically, BOQ preparation covers structural and architectural items — earthwork, PCC, RCC (foundation, columns, beams, slabs), masonry, plastering, flooring, and finishing — as distinct from electrical, plumbing, or interior BOQs, which are usually prepared as separate linked documents.
| Stage | What Happens |
|---|---|
| 1. Drawing study | Review architectural + structural drawings, specifications, and BOQ scope |
| 2. Quantity takeoff | Measure every item — volumes, areas, lengths — with formula backup |
| 3. Rate application | Apply DSR (government) or current market rate per item |
| 4. BOQ compilation | List items in construction sequence with quantity × rate = amount |
| 5. Abstract & review | Roll up into a summary, cross-check totals, finalize for submission |
Step-by-Step: How Civil Work BOQ Is Prepared
- Study the drawings and specifications — note the structural grade (M20/M25), brick vs block, plaster ratio, and flooring type, since these decide which rate applies to each item.
- Break the project into work sections — earthwork, foundation, superstructure (RCC + masonry), plaster, flooring, finishing — in the order construction physically happens.
- Take off quantities for every item — Length × Breadth × Height/Depth for volumes, Length × Breadth for areas, using the drawing dimensions directly, not rounded estimates.
- Assign units correctly — Cum for concrete/excavation, Sqm for plaster/flooring, Rmt for pipes/skirting, Ton for steel, No. for fittings.
- Apply rates — DSR (Delhi Schedule of Rates or state PWD schedule) for government work, current local market rates for private clients, split into material and labour where possible.
- Calculate amounts and compile the BOQ — Quantity × Rate = Amount for every row, grouped by work section with subtotals.
- Prepare the abstract of cost — sum every section subtotal, add GST and contingency (typically 3-5%), producing the final tender/client-ready number.
💡 Where civil work BOQs go wrong most often
Quantity takeoff errors in step 3 are the single biggest source of BOQ disputes — a wrong slab thickness or missed deduction throws off every downstream number. Our BOQ & Estimation Excel Templates automate this: enter your dimensions once, and quantity, rate, and abstract all update together, with the Civil Work Estimate & BOQ Template built specifically for this exact process.
Sample Civil Work BOQ (Structure)
| S.No | Description | Unit | Qty | Rate (₹) | Amount (₹) |
|---|---|---|---|---|---|
| 1 | Earthwork excavation in foundation | Cum | 52 | 185 | 9,620 |
| 2 | PCC 1:4:8 in foundation | Cum | 7 | 5,300 | 37,100 |
| 3 | RCC M20 footing/column/beam/slab | Cum | 38 | 7,900 | 3,00,200 |
| 4 | Brick/AAC block masonry | Cum | 45 | 6,600 | 2,97,000 |
| 5 | Internal + external plaster | Sqm | 480 | 290 | 1,39,200 |
| 6 | Flooring (vitrified tile) | Sqm | 140 | 850 | 1,19,000 |
A real civil work BOQ runs far longer than this once doors, windows, painting, electrical, and plumbing items are added — this sample shows only the structural core.
Build It Yourself, or Use a Ready-Made Structure
Preparing a civil work BOQ from a blank sheet is entirely possible — the challenge is consistency across projects and keeping the quantity-rate-amount chain formula-linked instead of manually typed. Our Professional BOQ & Estimation Templates give you that structure pre-built and CPWD/DSR compliant, so you spend your time on the numbers, not the format.

Frequently Asked Questions
What is BOQ preparation in civil work?
The process of converting drawings and specifications into a priced Bill of Quantities — measuring every civil item, applying a rate, and compiling it into a structured, verifiable document.
What is the first step in preparing a civil work BOQ?
Studying the approved architectural and structural drawings and specifications, since these determine what quantities need to be measured and which rates apply.
Is a civil work BOQ the same as an electrical or plumbing BOQ?
No — each trade has its own BOQ with different item types and units, though they’re often compiled together into one project-level document with a combined abstract of cost.
Can civil work BOQ preparation be automated in Excel?
Yes — with quantity, rate, and amount linked by formula, updating one input (like a dimension or rate) automatically updates the entire BOQ and abstract, which is how our templates are built.
