4. Five

The correct answer is: Four

In estimating, there are four basic categories of units that are commonly used. These categories include: 1. **Physical Units**: These are measurable quantities such as cubic meters, linear feet, or pounds that directly correspond to the items being estimated. 2. **Cost Units**: These focus on the cost associated with physical units. Cost units help in determining the total expenditure needed for materials, labor, and overhead. 3. **Time Units**: These units relate to the duration required to complete various tasks or segments of a project. They are essential for understanding the scheduling and delivery timelines. 4. **Labor Units**: These involve the amount of labor required to achieve specific outputs, often expressed in man-hours or work shifts. Understanding these four categories allows estimators to create more accurate and comprehensive estimates, as each type of unit contributes essential information to the overall assessment of a project's requirements and costs.
