What does 'fitting takeoff' refer to?

Fitting takeoff refers to the essential process of determining the quantity, size, and type of fittings required for a plumbing job. This process is critical in project planning and budgeting, as it directly impacts the material requirements and costs associated with the installation. By accurately identifying what fittings are necessary, a pipefitter can ensure that the project proceeds smoothly without delays caused by shortages or errors in material ordering. Additionally, this step is fundamental for creating a comprehensive plan that aligns the project's specifications with industry standards and regulations.

The other options touch on related aspects of plumbing and fittings but do not capture the core definition of fitting takeoff. Calculating costs is important for budgeting but comes after the takeoff process. Measuring angles is part of the installation phase rather than the initial assessment of fittings needed. Estimating installation time is relevant for project scheduling but does not pertain to the initial determination of fitting specifications.
