In this blog, we are going to learn about types of estimation of and Cost estimation methods.The construction cost estimation can be done with the help of a project estimator.For a construction process, there are different estimation process is involved different stages of construction.

## What are the Requirements of Estimation and Costing?

- The cost estimation method gives an idea about the cost of the civil works.
- Gives an idea about the amount of time required for the finishing of the project
- In order to invite tenders for the project, a preliminary estimate should be needed.
- It also helps to control the expenditure during the execution of works.
- Using estimate we can check whether the proposed plan matches the fund available.

**Types of estimation used in cost estimation method.**

Detailed estimate involves several sub-heads and the required amount of various items.Detailed estimate prepares only after the rough estimates are approved.You can prepare these estimates with the help of a project estimator.

In this estimate cost of each material, specifications and their quantity are attached to the estimate reports.

**3.Revised Estimate**

The revised estimate is only prepared when the detailed estimate exceeds the construction cost by 5 percent.In revised estimate, the project estimator should provide the reason for the increase in the construction cost.

**4.Supplementary Estimate.**

After the detailed estimate, if you want some extra work need to do for your plan.You need to prepare a supplementary estimate for your extra work.These estimates are added to the detailed estimate.
