Importance of rate analysis; how rates taken

Short answer

Rate analysis gives unit rates for estimates, shows material/labour/machinery per unit, and supports tender evaluation, variations and cost control. Rates are taken from departmental norms, District Rate or market survey, plus transport, then 15% overhead/profit and 13% VAT are added.

Why is analysis of rate important for civil engineering work? Also, explain how rates are taken for analysis.

Importance of rate analysis

  • It gives the unit rate of every item of work, without which an estimate or a bill cannot be prepared.
  • It gives the materials, labour and machinery per unit, so procurement and planning can be done.
  • It is the basis for evaluating tenders, valuing variations and settling extra-item rates.
  • It allows comparing alternative designs and methods and keeps the cost under control.

How rates are taken

  1. The quantity of materials, labour and equipment per unit of work is taken from the departmental norms (DUDBC norms for buildings, Department of Roads norms for road work).
  2. The rates of the materials and labour are taken from the District Rate of the concerned district (or from a market survey if the material is not listed).
  3. Transport is added for the lead from the source to the site.
  4. Cost per unit = norm x rate for each resource; the sum is increased by 15% contractor's overhead and profit.
  5. VAT (13%) is added in the estimate.
