BOQ & rate analysis in Nepal — the complete working guide

What a BOQ actually is (and what it is not)

A Bill of Quantities is the priced skeleton of a construction project: every measurable item of work — excavation, PCC, RCC, brickwork, plaster, painting — listed with its unit, its quantity taken off from the drawings, and a rate. Quantity times rate gives the amount; sections subtotal; the bill totals. That is the entire mechanism.

What a BOQ is not: a guess. When a client or a government office questions your price, the defence is never ‘that is the market rate’ — it is the rate analysis sheet behind each item showing exactly which materials, how much labour and what equipment the rate was built from. The BOQ is the summary; the rate analysis is the proof.

Rate analysis, the DUDBC-norms way

In Nepal, rate build-up follows the norms published by DUDBC (Department of Urban Development and Building Construction) and district rate schedules. The idea: for one unit of an item — say 1 m³ of M20 concrete — the norms tell you the resource quantities it consumes. You multiply each quantity by your district's current market rate, sum them, and that is the item's direct rate.

A typical build-up for 1 m³ of M20 (1:1.5:3) concrete: about 8.4 bags of cement, 0.45 m³ sand, 0.9 m³ aggregate, roughly 0.18 mason-days and 1.2 unskilled labour-days, plus mixer and vibrator time. At Rs. 850 a bag, Rs. 2,800/m³ sand and Rs. 3,200/m³ aggregate with Rs. 1,500 mason and Rs. 1,000 labour wages, the material-plus-labour rate lands around Rs. 12,000–13,000 per m³ before overheads — which is why a rate quoted far below that should worry everyone in the room.

The crucial habit: keep ONE resources table with today's market rates, and let every item's rate reference it. When cement jumps Rs. 60 a bag — and it will — you change one number and the whole bill re-prices. Engineers who hard-type rates into every row re-do the entire estimate instead.

Overhead & profit, and Nepal's 13% VAT

Direct cost is not the quotation. On top of the summed direct amounts you add overheads and profit — site supervision, office costs, financing, and the margin that keeps the firm alive. 15% is the common figure in Nepali practice; public entities often cap or prescribe it, so check the tender conditions.

Then VAT: 13% on the subtotal (direct cost + O&P) for VAT-registered work. Presenting it as its own labelled line — not buried inside rates — is both correct practice and what clients and auditors expect to see. The standard build-up reads: direct cost → + O&P% → subtotal → + 13% VAT → grand total.

How to build a BOQ in the free calculator, step by step

Step 1 — open the calculator (calenote.app/tools/boq-calculator, free, no sign-up) and name the project. Step 2 — open ‘Resources & rates’ and enter your district's current market rates for the materials, labour and equipment you will use. Step 3 — add sections the way the work packages break down (earthwork, concrete, masonry, finishing), then add items under each with unit and quantity from your take-off.

Step 4 — for each major item press the RA (rate analysis) button and enter the per-unit resource quantities from the norms; the item's rate turns green and computes itself. Minor lump-sum items can keep a manual rate. Step 5 — set your overhead & profit percentage, toggle 13% VAT if applicable, and read the grand total. Step 6 — export to Excel: the quotation sheet is client-ready, and the second sheet carries the full rate build-up of every analysed item as your supporting document.

Everything saves in your browser automatically, so you can close the tab mid-estimate and come back. Export to Excel for anything you must keep permanently — browser storage is convenience, not an archive.

The mistakes that sink estimates

Forgetting wastage — norms quantities are theoretical; sand washes away, bricks break, timber gets cut wrong. Bake realistic wastage into the recipe quantities rather than hoping the margin absorbs it. Mixing units — an item measured in m² priced with a per-m³ rate has ended careers; write the unit next to every rate. Copying last year's rates — cement, rebar and wages in Nepal move fast; re-check the resources table against current district rates before every submission.

And the quiet one: applying O&P inside individual rates AND again at the bottom. Double-counted margin makes you uncompetitive without you ever seeing where. Keep rates as pure direct cost and apply O&P once, visibly, at the end — which is exactly how the calculator is wired.
