How should doors be grouped on an estimate?

Grouping doors by material type and purpose is an essential practice in construction estimating. This approach helps in accurately assessing the cost and requirements for each type of door necessary for the project. Different materials (such as wood, metal, or fiberglass) may have distinct costs associated with them, as well as varying installation techniques and maintenance needs. Additionally, categorizing doors by purpose—such as interior, exterior, fire-rated, or security doors—ensures that the estimator is considering not only the material but also the door's function within the building's design.

This method enables a more streamlined estimating process, facilitating clear communication among stakeholders, accurate budgeting, and more effective project management. For instance, fire-rated doors will have specific code compliance requirements that differ from standard internal doors, which influences both cost and installation schedule. Thus, grouping by material type and purpose is not only practical but essential for a comprehensive and precise estimate.
