Answer 1

Explanation:

A Revised Estimate must be prepared under the following primary conditions:

When there are material deviations from the original proposal
This is the core reason stated in CPWD Works Manual, Schedule of Rates, and PWD Code.
Material deviation means:
- Changes in design
- Change in scope of work
- Change in site conditions
- Substitution of materials
  Even without exceeding cost, this alone is a valid and mandatory reason.

Additional Information

When a sanctioned estimate is likely to exceed by more than 5% either from the rates being found insufficient or from cause whatsoever except important structural alteration.
When the expenditure of works exceeds or is likely to exceed by more than 10% of the administrative approval (for work more than 5 lakhs/-)
