Electrical estimating is a process used by electricians, construction managers and engineers to determine the amount and cost of electricity required for a specific location or process. … This tool is designed for use by electricians, architects and electrical engineers.
What is an estimate in electrical engineering?
The method of computation of all required engineering materials and the expenditure likely to be incurred in carrying out a given work before the actual execution of work is called estimation. Hence an estimation includes calculation of quantity involved and quality aspects of the material required.
What is the purpose of estimating and costing in electrical engineering?
Estimating and costing thus serves the number of purposes in the construction process including preparation and finalize of bids and cost control. The main purpose is to provide to volume of work for cost control and to see that the adequate options of materials are explored during the execution of the project.
What is meant by estimation in engineering?
ESTIMATION Estimation is the scientific way of working out the approximate cost of an engineering project before execution of the work. • It is totally different from calculation of the exact cost after completion of the project.
What is estimating used for?
Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.
How do you estimate an electrical job?

What is difference between estimating and costing?
Estimating and Costing Definition
Estimating and Costing are closely the same things. The estimate is defined as the process of calculating or computing the various quantities and the expected expenditure to be incurred on a particular work or project. The estimate gives the probable cost of the work.
What is the purpose and importance of estimates?
The purpose of an estimate has a different meaning to different people involved in the process. To the owner, it provides a reasonable, accurate idea of the costs. This will help him or her decide whether the work can be undertaken as proposed, needs to be modified, or should be abandoned.
What are the types of estimation?
In this article, we’ll cover the following types of estimates:
- Preliminary Estimate.
- Detailed Estimate.
- Quantity Estimate.
- Bid Estimate.
Which data is required to prepare an estimate?
Data required for preparation of estimate:
- (i) Complete Set of Detailed Drawings: …
- (ii) Specifications of Items of Works: …
- (iii) Prevalent Rates of Items of Construction: …
- (iv) Standard Mode of Measurement: …
- (v) Details of foundation strata likely to encounter.
- (vi) The exact location of the work site.
What are the elements of estimation?
Most often cost estimating professionals break down the total cost of a project into these three elements: Direct Cost, Indirect Cost, and Markup. The relationship between the two models is Labor & Materials components are considered direct costs, overhead is indirect and profit fits in the markup category.
