From the table, the main factors influencing cost estimating decision are complexity of the project, scale and scope of construction, market conditions, method of construction, site constraint, client financial position, buildability and location of the project .
What are the factors of estimate?
An estimating factor is a parameter that is used in an estimating formula to calculate the estimated effort for a task or work breakdown element . Estimating factors used in Engineering Method Composer are: Name. The name of the estimating factor.
What are the factors that affect cost estimation?
The top ten factors affecting the accuracy of cost estimate are clear and detailed drawings and specification, experience of pricing construction projects, perception of estimation importance, equipment (cost/availability/performance) , project complexity, clear scope definition, accuracy and reliability of cost ...
What is a cost estimate?
Cost estimation in project management is the process of forecasting the financial and other resources needed to complete a project within a defined scope. Cost estimation accounts for each element required for the project—from materials to labor—and calculates a total amount that determines a project’s budget.
What are the several factors that might affect the accuracy of the estimated materials in building construction?

What indicates the accuracy of cost estimate?
Since a cost estimate is the approximation of the cost of a project or operation, then estimate accuracy is a measure of how closely the estimate is able to predict the actual expenditures for the project or operation . This can only be known after the project is completed.
Which factors control the cost of a project?
- High Raw Materials Prices.
- Control of Inventory.
- No control over Wage.
- Uneconomic size of Plant.
- Underutilization of Capacity.
- Credit System.
- Delay in issuing license.
- Unseen overheads.
What is purpose of estimate?
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 three basic types of cost estimating?
Understanding the Three Major Categories of Cost Estimates
Cost estimates are broken down into three categories that serve one of three basic functions: design, bid, and control . To establish a project’s financing, you must start with a design estimate or a bid estimate.
What should be included in an estimate?
- Job description. Explain the work you’ll be doing. ...
- Materials and labor. Provide a high-level view of the necessary materials and labor and the costs for each. ...
- Total cost. Clearly and correctly tally up the total costs of the project.
- This is a big one. ...
- Sales and company contact info.
Which of the following is the most important factor that can affect accuracy of cost estimation?
The survey revealed the most significant factors that affect the estimation accuracy are: The level of experience of estimation team , Client’s financial capabilities, experience of the project’s team, time allowed for estimation, complexity and constructability of the project, and the availability and prices for labor ...
