SHEET 01 · THE PROBLEM

CL. 1.0 — WHY BUDGETS FAIL

The three problems no contractor will tell you

Your contractor's quote is a black box

Most contractors give lump-sum quotes. No breakdown. No quantities. No way to verify if they're stealing cement bags or inflating steel tonnage.

Per square foot pricing hides fraud

₹1,800/sqft sounds simple. But it hides inflated brick counts, wrong mortar ratios, oversized pipe diameters — all ways contractors pad their pockets invisibly.

Five phases, zero unified picture

Structure, masonry, electrical, plumbing, interior — five contractors, five quotations, no reconciled total. You have no idea where ₹15 lakhs went.

FREE CALCULATORS vs NIRMANSHASTRA

CL. 3.5 — COMPETITIVE COMPARISON

Why NirmanShastra beats free calculators

Free online calculators steal your phone number and sell it to contractors. Here's what you actually get.

Feature	Free Online Calculators	NirmanShastra (₹499/phase)
Calculation method	✗Per sqft thumb rule — meaningless averages	✓Exact item-wise BOQ based on IS 456, IS 732, IS 1172
Material quantities	✗Vague guesses (₹8L for cement)	✓Exact: 412 bags OPC 53, 2.4 tonnes Fe500D steel
IS Code compliance	✗None — not even mentioned	✓25 IS codes verified, every quantity traceable to a specific clause
Contractor accountability	✗Zero — they sell your data to contractors	✓Line-by-line comparison — catch overcharging to the decimal
Local rates	✗Fixed city averages you cannot change	✓You enter local dealer rates — India average pre-filled as benchmark
CPWD labour	✗Not included	✓14 CPWD trades, productivity rates, fully editable
PDF report	✗No PDF — just a number on screen	✓Professional 10-page PDF with BOQ, IS compliance, site checklist
Your data	✗Sold to contractor lead networks	✓Never sold. Your project data is yours.

The math is universal. IS codes don't change by city. Only the rates do — and you control those.
