Which of the following is NOT a division category in MasterFormat?

MasterFormat is a standardized system for organizing construction project information and specifications into divisions and categories, allowing for clearer understanding and communication among project stakeholders. The divisions within MasterFormat encompass various aspects of construction, including materials, methods, and systems used in building projects.

Site Construction, Electrical, and Mechanical are all recognized divisions in MasterFormat that specifically cater to different areas of construction. Site Construction includes all work related to the site, such as grading and site preparation. Electrical covers the work associated with electrical components, installations, and systems. Mechanical encompasses systems related to heating, ventilation, air conditioning, plumbing, and other mechanical systems.

Structural Principles, however, is not categorized as a division within MasterFormat. It does not hold the same level of recognition and does not correspond to a specific section or division as defined by the standards established in MasterFormat. Instead, structural considerations are typically included within a broader category such as the Structural division, which handles specific considerations related to building structure and design, but not under the title of "Structural Principles." This lack of correspondence makes it clear that this option does not fit within the established framework of MasterFormat divisions.
