What is construction estimating?

Construction estimating refers to the determination of the amount of money needed for the completion of construction work. This involves estimating costs relating to materials, human resources, machines, and other items. There is a need to develop a realistic budget so that the project does not exceed the planned cost. 

Estimators collect all the data for example from the blueprints and specifications to establish the quantities and prices of the materials. They also look at the cost of labor which includes the money that may be used to pay workers and time used to accomplish the work. Furthermore, these include what is required for equipment like machines or implements. To make their estimations more precise, most estimators apply specific software.

Different Types of Construction Estimates

There are several different types of construction estimates, each serving a specific purpose. The type of estimate you use will depend on the stage of the project and the level of detail required. Some common types of construction estimates include:

1. Preliminary Estimate:

Also known as a conceptual estimate, this type of estimate is typically done during the initial stages of a project. It provides a rough cost estimate based on limited information and is used to determine the feasibility of the project.

2. Detailed Estimate:

A detailed estimate is a more comprehensive and accurate estimate that takes into account all aspects of the project. It involves a thorough analysis of the project scope, materials, labor, and other associated costs. Detailed estimates are typically used for budgeting and planning purposes.

3. Bid Estimate:

A bid estimate is prepared when a contractor or construction company is submitting a bid for a project. It includes a detailed breakdown of costs, allowing the client to compare different bids and make an informed decision.

4. Change Order Estimate:

Change order estimates are prepared when there are changes or additions to the original project scope. These estimates help determine the cost implications of the changes and ensure that the project stays within budget.

Using the appropriate type of estimate for each stage of the project is essential for accurate cost estimation and effective project management.

Process for Creating a Construction Estimate
