Classification System

A distribution of classes or categories created according to a common relation. In construction, there are several classification systems covering elements, spaces, disciplines, materials, among others (OmniClass is an example of a widely used classification system)

Read the term
  • Asset Class

    A category grouping Assets that share common characteristics, functions or information requirements (e.g. pumps, lifts, bridges). Asset Classes are typically defined using a Classification System and structure the Asset Hierarchy

  • Asset Hierarchy

    A Taxonomy of different Asset Scales across the Built Environment…also refer to Built Asset

  • International Framework for Dictionaries

    IFD is a library of construction terminology that defines the use of a particular 'names? (e.g. doors, windows, etc...), their types and properties in a consistent manner across countries and languages

  • ISO 12006-2

    Building construction - Organization of Information about Construction Works - Part 2: Framework for Classification (ISO 12006-2:2015)

  • ISO 12006-3

    Building Construction - Organization of Information about Construction Works - Part 3: Framework for Object-oriented Information

  • Naming Convention

    Naming conventions refer to terms used across an industry to describe an object or a property (also refer to Naming Protocol)

  • OmniClass

    OmniClass (OCCS) is a Classification System for organizing library materials, product literature and project information. OmniClass has 15 'classification tables'; some of which are incorporated from other classification systems including: MasterFormat (a classification for 'work results') and UniFormat (a classification of 'construction elements'). OmniClass is an Open Standard developed by the Construction Specifications Institute (CSI)

  • Taxonomy

    A Taxonomy is a multi-level classification (a hierarchy, tree, etc.) introduced to organize concepts according to a clear structure. As a Knowledge Content Type, it applies to publications which introduce classifications of five or more items within a structured list; and which have a clear use in assessment, learning or implementation (e.g. a classification of BIM roles, data exchange types or levels of detail)

  • Uniclass

    Uniclass 2015 is a Classification System for the UK construction industry, covering Asset Scales from facilities and infrastructure to systems and products. Its coordinated tables include Complexes (Co), Entities (En), Activities (Ac), Spaces/locations (SL), Elements/functions (EF), Systems (Ss), Products (Pr), Tools and Equipment (TE), Project Management (PM), Form of Information (FI) and CAD-related classifications (Zz).
