A project construction cost estimate includes: A. The labour and material cost B. The equipment and over head cost C. The profit of the contractor D. All of these

The correct answer is D. All of these.

A project construction cost estimate includes the following:

• Labour and material cost: This is the cost of the materials and labor that will be used in the construction of the project.
• Equipment and overhead cost: This is the cost of the equipment and other overhead costs that will be incurred during the construction of the project.
• Profit of the contractor: This is the profit that the contractor expects to make on the project.

The labour and material cost is the most significant component of the project construction cost estimate. The equipment and overhead cost is also a significant component, but it is usually less than the labour and material cost. The profit of the contractor is usually a small percentage of the total project cost.

The project construction cost estimate is used to determine the total cost of the project. This information is used to make decisions about whether or not to proceed with the project, and to determine the financing for the project.
