Number	Where to get the REAL figure	Status
All-in build cost $/sqft	IMAJ (builders assoc.) · a JIQS quantity surveyor	⚠ QS quote
Site infra (roads/water/power/drainage/terracing per lot)	Civil contractor quote · NWA/NWC/JPS developer guides	⚠ no published JA figure

Honest verdict: material prices, duties, permit & title fees, and the FX are verified from real JA sources (above). The build-$/sqft, site-infrastructure, specialty-item, and sale-price numbers in the calculator are DRAFT estimates — this page is where you replace them with real quotes. NOAH will always cite a source or mark a number unverified — never present an estimate as fact.
