- 2
  
  2.5%
- 3
  
  4.0%
- 4
  
  5.0%
Answer: 4
Explanation:
A Revised Estimate is prepared when the expenditure of a work is likely to exceed the amount of the original sanctioned estimate by more than 5%, due to:
- Increase in rates of materials or labour
- Change in quantities
- Alteration in design or specifications
Therefore, if the cost exceeds the sanctioned estimate by 5% or more, a revised estimate is required.

✅ Answer: 4. 5.0%

Exam Tip
- Revised Estimate → Excess over sanctioned estimate > 5%
- Supplementary Estimate → For additional items not included in the original estimate.
10) Question.

The most reliable estimate is
Answer.
- 1
  
  Detailed estimate
- 2
  
  Preliminary estimate
- 3
  
  Plinth area estimate
- 4
  
  Cube rate estimate
Answer: 1
Explanation:
A Detailed Estimate is the most reliable estimate because:
- It is prepared from complete drawings and specifications.
- Quantities of all items are worked out in detail.
- Rates are applied item-wise.
- It gives the most accurate cost of the project.
Other estimates are approximate:
- Preliminary Estimate → Rough estimate for administrative approval.
- Plinth Area Estimate → Based on plinth area rate.
- Cube Rate Estimate → Based on volume of the building.
Reliability Order
1. Detailed Estimate ✅ (Most accurate)
