Building system Uniclass definition
Uniclass is a voluntary classification system for the construction industry that can be used for structuring project information, such as building information models (BIM). It was created in 1997 by the Construction Project Information committee (CPIC).
The Uniclass classifications, state that:
“Systems are typically single-trade built objects made up of several products, collectively serving a common purpose, such as the load-bearing blockwork inner skin of an external wall Element. In ISO 12006-2, they roughly equate to the concept of ‘designed elements’.”
ISO 12006-2 is the international standard: Building construction -- Organization of information about construction works -- Part 2: Framework for classification.
“Systems are the collection of components that go together to make an element or to carry out a function. For a pitched roof, the rafters, lining, tiles, ceiling boards, insulation and ceiling finish comprise a system, or a low temperature hot water heating system is formed from a boiler, pipework, tank, radiators etc. A signal system for a railway has a number of components and products; and the scum removal system is part of a wastewater treatment entity.”
