A lump sum, no quantities
Many quotes give one total. You cannot see how many bags of cement or kilos of steel it counts, so you cannot check it.
For people building their own home
Know exactly how much your house needs
before you place the order.
Tell us the size of your house. We work out its frame the way an engineer would, then tell you how much concrete, steel, cement, bricks and sand it needs. Exact quantities, so every quote you get can be checked against them.
- Exact quantities. Add your own rates to see the rupees.

- Checked against Indian Standards
What does the frame of your house look like?
The frame is the part that holds the house up: foundation, columns, beams and slabs. Move the sliders and see how an engineer would lay it out.

Laying out the frame…
This is the shape of the frame for a typical plot, with columns about every 3.75 m. Your own plot and plan will change it. How much concrete, steel and cement the frame takes is in the full report.
Want the quantities for your own plan?
The full report sizes every footing, column, beam and slab for your plot, then counts the concrete, the steel by bar size, and the cement, sand and aggregate to buy. Exact quantities. Add your own rates to see the rupees.

A typical plot is taken to be 1.3 times as long as it is wide. Columns go about every 3.75 m, which is usual for houses, and never more than 5 m apart. The full report goes on to size each member to IS 456:2000, IS 875 and IS 1893 and counts the materials.

Before you sign anything
Why quotes are so hard to check
It is not always dishonest. A quote just rarely says how much of anything it counts. Here is what gets in the way.
One rate per sq ft hides the details
A single rate per sq ft sounds simple. But brick counts, mortar mix and pipe sizes can quietly change inside it.
Five trades, five lists, no total
Structure, brickwork, electrical, plumbing and interiors are each counted their own way. Nobody puts them into one list of what to buy.
The house, step by step
Eight steps. One list.
Watch a small house go up in the order it is really built: the concrete frame first, the walls after, the finish last. Every step is something you have to order, so you know what a quote should count.

Play with the numbers
Three small tools you can use right now. Move a slider, see the answer, and open “Show the calculation” only if you want to see how it was worked out.
Steel rings in a column
Inside a column, tall steel bars are held in place by small steel rings called ties. Rings are an easy place to quietly save steel, so it helps to know how many there should be. Move the controls and watch the count change.
Width of the column
Ring spacing, middle of the column
Steel rings in one column
26rings
6 more than rings spaced evenly at 150 mm. The extra rings are what keep a column strong in an earthquake.
How we got this
- Ring spacing near the ends
a quarter of 350 mm is 87.5 mm, but never more than 100 mm87.5 mm - Rings near the two ends
500 mm · each end zone is the largest of: the column width, a sixth of the height, or 450 mm12 - Rings in the middle
150 mm14 - Rings per column26
- If evenly spaced at 150 mm
3000 mm ÷ 150 mm20
Near the ends of a column the rings sit closer: a quarter of the column width or 100 mm apart, whichever is less. This shows how the rule works; it is not a structural design. Concrete cover over the steel is at least 40 mm in a column.

How many bricks does my wall need?
A one-brick wall takes 94 to 104 bricks for every square metre, depending on the size of the brick, because the wall is two bricks deep behind the face you see. Pick your brick and wall, then watch one metre go up.

What strength of concrete do I need?
Concrete is sold by grade, like M20 or M25. The number is how hard a test cube can be squeezed after 28 days before it cracks. The harsher the site, the stronger it must be. Pick your site and the size of the pour, then crush the cube.

How harsh is your site?

For the 12 m³ you are pouring, plan on about 96 bags of cement. Your site sets this minimum, so a weaker mix is not allowed.

M20 uses the nominal-mix cement figure of 8 bags per m³ (CPWD Analysis of Rates 2014). Grade number = characteristic compressive strength in N/mm². The gauge shows that value, not a lab result. Water is a ceiling, not a target. Code ceiling on cement: 450 kg/m³.

Check a quote
Does your contractor’s quantity hold up?
A price only means something if you know what it counts. Ask your contractor for the quantities behind the quote: bags of cement, kilos of steel, cubic metres of concrete. Our report counts the same things for your house, with an honest range, and tells you for each line whether it is low, inside the range or high.
Which line of the quote?
Where does it sit against our range?
Low endMost likelyHigh endYour quote · Steel
Above our range. Ask how the weight was worked out: from cutting lengths with laps, or from a thumb rule. Check that wastage and binding wire are not counted twice.
A picture of how a line reads. The numbers for your own house are in the report. This covers only the frame: footings, columns, beams, slabs and stair. It is not a formal quotation, a rate check or a structural approval.
Why there is a range at all
A quantity worked out from a drawing is still not one exact number: bar lengths are cut and lapped on site, shuttering is reused, and some wastage is unavoidable. The report therefore gives a range around its most likely figure. It is wider for steel and shuttering, which are decided on site, than for concrete, which is measured from the drawing.

Free calculators vs NirmanShastra
How we compare with free calculators
A free calculator is fine for a rough idea. Here is what you get when you want quantities you can take to your contractor.

How the quantities are worked out✕A rough rate per square foot✓The frame is laid out and sized to the Indian Standards, member by member, on our servers

Prices, rates and labour✕City averages that go out of date✓None of ours. If you want the rupees you type your own dealer’s rates, so nothing goes stale and nothing is guessed about your local market. Labour, transport and taxes are not included

The arithmetic is the same everywhere. What differs is how much of the house it looks at, and whether it shows its working.
Built on Indian Standards
Every number follows the official rulebook
The quantities in your report are not guesses. They are worked out from the Indian Standards listed here, published by the Bureau of Indian Standards, the same rules your engineer works to. You never have to read them. They are here if you want to check.
The 28 standards behind the reports
Ticked · 0 / 28See every clause
Press a standard to tick it off as you check it. A few of the values the free calculators use: M20 concrete is a 1 : 1.5 : 3 mix (not 1 : 2 : 4). The dry volume factor for concrete is 1.54, and for mortar 1.1.
Pay per report. Start free.
On a house costing ₹30–80 lakh, a single wrong line in a quote (10 extra bags of cement, or 100 kg of extra steel) usually costs more than the report.
