Questions
Why do I need to enter the rate?
Construction rates change frequently with cement, steel and labour prices and differ by city and finishing level. A current local quote is far more reliable than a national average.
What is covered area?
The total built floor area across all storeys, not the plot size. A 10-marla double-storey house may have 2,000–2,500 sq ft covered.
