Build a unit rate the way a tender does — material + labour + machinery, plus water/sundries and the contractor's overhead and profit. Enter the per-unit costs and see exactly where the rate comes from.

Where the rate comes from
This is the analysis-of-rates structure CPWD and PWD tenders use. Enter the per-unit material and labour from the current material rates and labour rates — the water/sundries (~1.5%) and the 10–15% overhead-and-profit on top give the billed rate.
How it works (analysis of rates)
- Prime cost = material + labour + machinery for one unit of work.
- Water & sundries ≈ 1.5% of the prime cost.
- Overhead + profit ≈ 10–15% on top — the contractor's margin.
- Unit rate = prime + sundries + overhead & profit. Multiply by the quantity for the total.
Worked example
For 1 m³ of RCC — material ₹6,000, labour ₹1,500, machinery ₹200:
- Prime cost = ₹7,700; + 1.5% sundries = ₹7,815
-
- 15% overhead & profit ≈ ₹8,988 per m³
- For 10 m³, the total is about ₹89,878
Frequently asked questions
What is rate analysis in construction? Working out the rate for a unit of work by adding up its material, labour and machinery, then the water/sundries and the contractor's overhead and profit — the basis of every tender and BOQ rate.
How much overhead and profit is added? Usually 10–15% on top of the prime cost plus sundries, covering site establishment, supervision, tools and the contractor's margin.
Why add 1.5% for water and sundries? Water for curing and mixing, small tools and consumables that are real costs but too small to bill line by line — added as a percentage of the prime cost.
Where do I get the per-unit rates? Take current material rates from the price lists and labour from the labour-rate pages, work out how much of each a unit of work needs, and enter the totals here.
