What is the correct sequence of preparing an estimate? 1. Detailed estimate 2. Approximate estimate 3. Supplementary estimate 4. Revised estimate Correct Answer 2, 1, 3, 4

Explanation:

Types of estimates

Characteristics/Properties

1. Supplementary estimate

 

While a work in progress some additional works may be thought necessary for the development of a project which was not foreseen when the original estimate was framed, the estimate when prepared to cover all such works are known as a supplementary estimate.

2. Cube Rate Estimate

This type of estimate done by multiplying the volume of the building by the unit cubic rate achieved from the previously (also recent) estimate.

3. Plinth Area Estimate
  • Plinth area estimate can be achieved by multiplying the values of plinth length, plinth width & plinth area rate. Here the plinth area is referred to as the external plinth area of the building at floor level.

4. Revised estimate

When sanctioned estimate is exceeded by more than 5% either from rates being found insufficient due to change in the price level or from any cause except important structural alterations.

5. Preliminary estimate/Approximate estimate

An approximate estimate made to find out the approximate cost in a short time.

6. Complete estimate

An estimate of all the items which are related to the work in addition to the main contract or the detailed estimate.

7. Detailed Estimate

Includes the quantities and cost of everything required for satisfactory completion of work.

 

The correct sequence of preparing an estimate is Approximate estimate, Detailed estimate, Supplementary estimate, and Revised estimate.
