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.

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)

  1. Prime cost = material + labour + machinery for one unit of work.
  2. Water & sundries1.5% of the prime cost.
  3. Overhead + profit10–15% on top — the contractor's margin.
  4. 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.
