What is the primary basis for estimating costs in construction projects?

The primary basis for estimating costs in construction projects often relates to specific measurable units, making the concept of cost per cubic yard highly relevant. This approach allows contractors to quantify the volume of materials required for a project, which is particularly beneficial for estimating expenses related to concrete, soil, and other volumetric materials. By determining the cost associated with each cubic yard, contractors can create accurate forecasts for materials needed, thus providing a reliable framework for overall project costs.

Using a measurement like cost per cubic yard helps standardize estimates across various types of projects. It allows contractors to calculate not only the material costs but also helps in budgeting for additional factors such as labor and equipment based on the amount of material needed.

The other options, while related to estimating costs, do not provide the same level of granularity and precision as cost per cubic yard. For instance, fixed rates per project may be useful for straightforward projects but do not account for variations in material use effectively. Similarly, hourly wage for workers lacks the necessary scope by focusing solely on labor without considering material costs. The overall project budget can encompass broader financial factors but is less precise in estimating specific construction costs compared to direct material costs. Thus, the practice of estimating costs based on cost per cubic yard is vital for
