Reading a structural quote: cement grades, steel weight and what is padded
Two quotes for the same frame can differ by a third, and the reason is rarely the rate.
Structural work is where a homeowner has the least intuition and the largest sum at risk. The good news is that it is also the most measurable part of a build. Concrete is quoted in cubic metres, steel in kilograms, and both are computable from the drawings before anyone quotes.
For a typical Indian residential frame, steel consumption lands somewhere around 3.5 to 5 kg per square foot of built-up area. Below three, ask what has been left out. Far above five, ask whether the design is over-reinforced because nobody wanted to do the calculation properly. Neither answer is automatically wrong, but both deserve a reason.
Grade matters and is easy to check. M20 and M25 are the usual concrete grades for residential slabs and columns; the mix design and cube test results should be on record. Fe500D steel is standard. A quote that does not state grades is not a specification, it is a wish.
The single most useful thing you can do is get the bar bending schedule. It converts an argument about price into an argument about quantity, which is a much easier argument to win.
