What are standard material elements that regularly group together called?

The term that refers to standard material elements that regularly group together is "Assemblies." In construction and architecture, an assembly consists of a combination of individual components that work together to fulfill a specific function or purpose within a building or structure. For example, a wall assembly might include framing members, insulation, sheathing, and finish materials all grouped together because they collectively constitute a wall.

Assemblies are widely used in construction documentation to simplify the design and construction process by allowing designers and builders to reference groups of components rather than detailing each individual part. This approach helps streamline material estimates, cost calculations, and assembly instructions since it encapsulates all necessary components into a single entity.

The other terms may relate to construction or manufacturing, but they do not specifically denote a grouping of standard material elements as commonly defined in construction practices. Kits may imply a packaged set of components but do not necessarily emphasize the assembled nature or regularity of the items. Parts refer to individual components of a system without the indication of their grouping. Bundles could also refer to a collection but lacks the specificity and functionality that assemblies provide in construction documentation.
