Which two activities are major parts of a takeoff?

The correct choice, which identifies counting and measuring as major parts of a takeoff, highlights the essential activities involved in quantifying materials and quantities needed for a construction project. A takeoff is the process by which all the quantities of materials needed to complete a project are determined from the construction documents.

Counting refers to the act of identifying and quantifying each item specified in the plans, such as fixtures, fittings, and other discrete elements. Measuring involves determining the physical dimensions of materials or spaces, allowing for accurate assessment of quantities, such as square footage for flooring or linear footage for piping. Together, these activities form the basis of an accurate takeoff, which is crucial for subsequent processes like estimating costs and preparing for procurement.

The other options contain activities that, while they are essential in the overall construction process, do not directly pertain to the takeoff itself. For instance, pricing and estimating relate to the financial assessment of project costs after quantities have been determined. Scheduling and planning focus on the timeline and sequence of tasks in project execution, which again occurs after the takeoff is complete. Similarly, coordinating and specifying involve managing various aspects of the project but are not part of the foundational activities involved in measuring and counting quantities.
