Measurement sheet format: columns, worked examples, and how it feeds the RA bill

A BOQ says what a fit-out should contain. An RA bill asks to be paid for what it does contain so far. The document in between, which proves how many square metres of tile, paint and ceiling actually went in, is the measurement sheet. On government work it ends up in the measurement book (MB). On private interior jobs it’s often a spreadsheet tab or a signed printout. Either way, every rupee you bill rests on it.

What a measurement sheet is

A measurement sheet is the site record of executed work. For each BOQ item, it lists every location where the work was done, with its dimensions and the quantity they produce. Three things make it useful:

• It’s tied to the BOQ. Every line carries a BOQ item number and the BOQ’s unit. A measurement that maps to no BOQ line is either a variation that needs approval or work nobody agreed to pay for.
• It shows the working. “Flooring: 120 sqm” is a claim. “Open office 9.60 × 7.50 = 72.00” is evidence that anyone can re-measure.
• Both sides agree it. In CPWD contracts, the contractor records the measurements and the Engineer-in-Charge checks them. With a computerised measurement book, both then sign with dates in token of their acceptance.

Strictly, the sheets are the working pages and the MB is the bound record they end up in. Under CPWD’s General Conditions of Contract 2023, checked sheets are submitted as a bound measurement book with machine-numbered pages, and no cutting or overwriting is allowed after that. On a private fit-out, a numbered and signed set of sheets does the same job.

The measurement sheet format

Column	What it holds
Item no.	The BOQ item it belongs to, which links it to the rate
Description / location	What was done, and where
Nos	How many identical units (two identical cabins = 2)
Length (m)	First dimension
Breadth (m)	Second dimension
Height / depth (m)	Height for walls, depth or thickness for volumes; blank for floor and ceiling areas
Quantity	Nos × L × B × H, using the dimensions that apply
Unit	The same unit as the BOQ line: sqm, rmt, cum, nos

Three conventions keep it clean:

• Consistent order: length, then breadth, then height or depth. IS 1200, the BIS method of measurement for building and civil engineering works, has long asked for that sequence.
• Two decimals: dimensions to the nearest 0.01 m and areas to the nearest 0.01 sqm, the precision IS 1200’s trade parts have long used.
• Deductions on their own lines. Measure the gross area, then write each deduction as a separate line in brackets, so the checker can see what was taken out.

Agree the rules before you measure. Whether an opening gets deducted is a rule, not a judgement call. CPWD contracts measure to their specifications first (unless the item description says otherwise), then to the relevant BIS method of measurement, then to a mutually agreed method. Private clients often write the rule into the BOQ. One SBI branch-interior BOQ, for example, does not deduct false-ceiling cut-outs smaller than 0.5 sqm each. Whatever applies on your job, write it at the top of the sheet.

Worked examples: flooring, painting, false ceiling

Columns that don’t apply are left out below. Flooring (BOQ item 2: vitrified tiles, sqm, ₹1,180), measured as laid:

Item	Description	Nos	L (m)	B (m)	Qty (sqm)
2.1	Open office	1	9.60	7.50	72.00
2.2	Cabins (identical)	2	4.20	3.00	25.20
2.3	Conference room	1	4.80	3.75	18.00
2.4	Pantry	1	2.50	2.40	6.00
2.5	Deduct: service shaft	1	1.20	1.00	(1.20)
	Net to date				120.00

120.00 sqm × ₹1,180 = ₹1,41,600. Skirting is usually its own BOQ line, often in running metres with the height stated, as older editions of IS 1200’s flooring part specify. Don’t fold it into the floor area.

Wall painting (BOQ item 5: plastic emulsion, two coats, sqm). There are two identical 4.20 × 3.00 m cabins, painted up to the 2.70 m ceiling level. For walls, the length is the perimeter: 2 × (4.20 + 3.00) = 14.40 m.

Item	Description	Nos	L (m)	H (m)	Qty (sqm)
5.1	Cabin walls (perimeter)	2	14.40	2.70	77.76
5.2	Deduct: doors	2	1.00	2.10	(4.20)
5.3	Deduct: windows	2	1.50	1.20	(3.60)
	Net				69.96

The rule here deducts openings over 0.5 sqm and ignores smaller ones, such as switchboards. Painting rules can be far more detailed. The 1994 edition of IS 1200’s painting part, for instance, deducted openings of 0.5 to 3 sqm from only one face of a wall finished alike on both sides. BIS revised that part in 2024, so name the rule rather than assume it. Keep ceilings on a separate line from walls.

False ceiling (BOQ item 3: grid ceiling, sqm, ₹950), finished over part of the job so far:

Item	Description	Nos	L (m)	B (m)	Qty (sqm)
3.1	Open office, bay A	1	9.60	5.00	48.00
3.2	Cabin 1	1	4.20	3.00	12.60
3.3	Deduct: duct opening	1	1.20	0.50	(0.60)
3.4	Light fittings, 0.36 sqm each	12	—	—	not deducted
	Net to date				60.00

60.00 sqm × ₹950 = ₹57,000. This applies the SBI-style 0.5 sqm cut-out rule: the 0.60 sqm duct opening is deducted, and the light fittings are not. The fittings are still listed, which shows the checker the rule was applied and not forgotten.

How the measurement sheet feeds the RA bill

The sheet’s totals go into an abstract, with one line per BOQ item and the cumulative quantity measured to date. The RA bill works on those quantities:

BOQ item	Rate (₹)	Measured to date	Previously billed	This bill (qty)	This bill (₹)
Gypsum partition (sqm)	1,450	40.00	24.00	16.00	23,200
Vitrified flooring (sqm)	1,180	120.00	60.00	60.00	70,800
Grid false ceiling (sqm)	950	60.00	30.00	30.00	28,500
Total					1,22,500

These are the same three lines as in our RA bill guide. The measurement sheet is where its “qty executed to date” column comes from, before retention, advance recovery and GST are applied.

Two habits keep the hand-off clean. First, measure cumulatively. If each sheet covers only one month, someone has to add them up across bills, and that’s where quantities get counted twice or dropped. Second, cite the sheet or MB page on every bill line. On CPWD works estimated above ₹20 lakh, RA bills are submitted by a date fixed each month, on the basis of the recorded measurements, and the measurement book is entered in the Division Office’s register before the bill is submitted for payment.

Checking and sign-off

These practices follow CPWD’s General Conditions of Contract 2023, and they work just as well on a private fit-out:

1. Measure jointly, at an agreed interval. The contractor records the measurements and the client’s engineer checks them, on a programme agreed in advance, not all in bill week.
2. Get dated signatures from both sides. For a computerised measurement book, CPWD requires them from the Engineer-in-Charge and the contractor or their representatives. Until both have signed, a sheet is only a draft.
3. Never overwrite. CPWD allows no cutting or overwriting in the final book. An error means a fresh book, after the old one is cancelled. On a private job, strike through, rewrite and initial.
4. Measure before you cover up. CPWD requires at least seven days’ notice before work is covered. Work covered without that notice or written consent is uncovered at the contractor’s cost, or not paid for. Screeds under tiles and concealed conduits are typical examples.
5. Don’t treat payment as final. Under CPWD’s conditions, checking and interim payment are not conclusive. The contractor stays liable for over-measurement until the defects liability period ends.

Where measurement leaks money

1. Work nobody measured. Covered-up layers, small items, and the corner finished after the measurement walk all fall off the bill. If it isn’t on a sheet, you can’t bill it.
2. Rules argued after the fact. If deductions weren’t agreed up front, every sheet becomes a fight over gross versus net.
3. Measured work with no BOQ line. An extra partition the client asked for on WhatsApp can be measured perfectly and still get stuck at billing, because there’s no approved rate for it. An approved variation is what gives a measured quantity an agreed price.

Keeping measurement, BOQ and bills on one baseline

Each of those leaks happens at a hand-off: from site to sheet, from sheet to abstract, or from variation to BOQ. Boqos is built around those hand-offs for interior fit-out firms. The BOQ is generated from scope and locked as the estimate, and every variation is documented, priced and client-approved before the work starts. Daily progress reports and site photos are linked to the project’s commercial record, and invoices go out against approved milestones.

A disciplined spreadsheet still works fine for one site. Once you’re running several, our BOQ software guide compares the options.

The short version

A measurement sheet is the signed, line-by-line proof of what was built: BOQ item, location, Nos × L × B × H, quantity and unit. Deductions go on their own lines, dimensions are to 0.01 m and totals are cumulative to date. Its totals feed the RA bill’s “executed to date” column. Agree the rules first, measure jointly, sign and date, and never let work be covered before it’s measured.
