How construction work
is actually priced.

Two contractors can quote the same building and produce numbers that are not comparable, because they are not pricing the same arrangement. Before comparing any figures at all, it is worth knowing which of the three you are being offered.

The three arrangements

Almost every construction contract in India is a version of one of three things. In a labour rate contract the client buys materials and the contractor supplies labour and supervision. In an item rate contract the contractor supplies both, priced element by element against measured quantities. In a lump sum contract the contractor supplies both for a single price covering a defined scope.

They differ in who carries the risk of quantities being wrong, of material prices moving, and of the drawings changing. That is the only difference that matters, and it is worth being explicit about it rather than choosing by which number looks lowest.

Labour rate

The contractor is paid for labour and supervision, usually per square foot of built-up area or per unit of work. The client buys cement, steel, aggregate, blocks and everything else directly.

1. What it suits A client who has the time to procure, the storage to hold material on site, and someone who can check what arrives. It is common for self-built houses and for owners already in the trade.
2. Where the risk sits With the client. If material runs out mid-pour, or the wrong grade arrives, or theft occurs from the site store, it is the client's problem and the client's cost.
3. What it hides The rate looks low because it is only part of the job. Comparing a labour rate against an item rate is comparing a component against a total.
4. What to watch Wastage. When the contractor is not buying the material, nothing in the arrangement rewards using less of it. Agree how wastage is measured before work starts, not when the third cement order is placed.

Item rate

Each element of work is priced separately - excavation per cubic metre, concrete per cubic metre, plaster per square metre, steel per kilogram - and the contractor is paid for the quantity actually executed, measured and recorded.

1. What it suits Work where the design is reasonably settled but exact quantities will only be known as the job proceeds. It is the standard arrangement for most contracted building work for good reason.
2. Where the risk sits Shared. The contractor carries the rate, the client carries the quantity. If more excavation is needed than expected, the client pays for more excavation at an agreed rate rather than negotiating a new price under pressure.
3. Why it is checkable Every variation has a rate already attached to it, so a change in scope becomes arithmetic rather than an argument. This is the main practical advantage and it is worth a great deal when something changes at month seven.
4. What to watch Measurement. An item rate contract is only as good as the record of what was measured and when. Agree who measures, how often, and what happens when the two sides disagree.

An item rate schedule also tells you what is not in the price. Anything absent from the list was not priced, and it will arrive later as a variation.

Lump sum

One price for a defined scope. The contractor absorbs the quantity risk and usually the material price risk over the contract period.

1. What it suits A complete drawing set and a specification that is genuinely finished. Fit-outs, repeat unit types and works with a hard opening date are the usual candidates.
2. Where the risk sits With the contractor - which means it is priced in. A lump sum for a scope nobody has fully defined is either padded to cover the unknown or heading for a dispute when the unknown appears.
3. Why it is attractive It gives the client one number to plan around, and for a fixed opening date that certainty can be worth more than the premium.
4. What to watch The scope definition is the contract. If it is a paragraph, the price means very little. If it is a drawing set and a specification, it means a great deal.

Which one fits

The question that decides it is not budget. It is how complete the drawings are.

• If the structural design and drawings are finished and will not move, a lump sum is available and gives the most certainty.
• If the design is settled in principle but quantities will firm up during execution, item rate is usually right.
• If the client wants to buy material directly and has the capacity to manage it, labour rate works - and is genuinely cheaper only if that capacity actually exists.
• If the drawings are not finished, no arrangement fixes that. A price against incomplete drawings is an estimate against assumptions, whatever it is called.

What to settle first

Whichever arrangement is used, a few things belong in the agreement rather than in memory.

1. What is included In writing, item by item. Most disputes are about scope, not about rates.
2. How variations are priced The rate for extra work, agreed before any extra work exists. Negotiating it afterwards never goes well for the client.
3. How and when measurement happens Who records it, how often, and what happens when the two sides read the same wall differently.
4. Payment against progress Tied to work completed and measured, not to the calendar.
5. What material testing is required Concrete cube tests and steel test certificates, and who pays for them.
6. What handover means The snagging list, who prepares it, and what has to be closed before the final payment is released.

None of this requires trusting anyone less. It makes the job easier to run for both sides, because the awkward conversations happen while they are still cheap.
