Building element

Uniclass is a voluntary classification system for the construction industry that can be used to structure project information, such as building information models. It was created in 1997 by the Construction Project Information committee (CPIC).

According to the Uniclass classifications, ‘elements’ are:

“…multi-trade built objects, made up of several systems, collectively serving a common purpose. They start life as un-designed objects such as ‘external walls’ with performance attributes such as U-values attached, but become steadily more defined as design decisions are made during the project.”

The most recent version of Uniclass, Uniclass 2015, (maintained and updated by the NBS) suggests that:

“Elements are the main components of a structure like a bridge (foundations, piers, deck) or a building (floors, walls and roofs).”
