ORGANIZATION: Construction Specifications Institute
This project is being ccordinated by the Construction Specifications Institute - CSI. Please contact the chair to become involved in the update of any of the tamles of Omniclass:
Table 11 - Construction Entities by Function
Construction Entities by Function are significant, definable units of the built environment comprised of elements and interrelated spaces and characterized by function.
Table 12 - Construction Entities by Form
Construction Entities by Form are significant, definable units of the built environment comprised of elements and interrelated spaces and characterized by form.
Table 13 - Spaces by Function
Spaces by Function are basic units of the built environment delineated by physical or abstract boundaries and characterized by function.
Table 14 - Spaces by Form
Spaces by Form are basic units of the built environment delineated by physical or abstract boundaries and characterized by physical form.
Table 21 - Designed Elements
An Element is a major component, assembly, or "construction entity part which, in itself or in combination with other parts, fulfills a predominating function of the construction entity" (ISO 12006-2). Predominating functions include, but are not limited to, supporting, enclosing, servicing, and equipping a facility. Functional descriptions can also include a process or an activity. A Designed Element is an "Element for which the work result(s) have been defined." (ISO 12006-2).
Table 22 - Work Results
Work Results are construction results achieved in the production stage or phase or by subsequent alteration, maintenance, or demolition processes and identified by one or more of the following: the particular skill or trade involved; the construction resources used; the part of the construction entity which results; the temporary work or other preparatory or completion of work which is the result.
Table 23 - Products
Products are components or assemblies of components for permanent incorporation into construction entities.
Table 31 - Phases
Life cycle phases are often represented by two terms used somewhat interchangeably in our industry. For the purposes of clarity and standardization, OmniClass defines these terms:
Stage: A categorization of the principal segments of a project. Stages usually are: Conception, Project Delivery Selection, Design, Construction Documents, Procurement, Execution, Utilization, and Closure.
Phase: A portion of work that arises from sequencing work in accordance with a predetermined portion of a Stage. For purposes of usage in OmniClass classifications, a Stage is a higher-level of categorization and a Phase is a subordinate level of titling within a Stage.
Table 32 - Services
Services are the activities, processes and procedures relating to the design, construction, maintenance, renovation, demolition, commissioning, decommissioning, and all other functions occurring in relation to the life cycle of a construction entity.
Table 33 - Disciplines
Disciplines are the practice areas and specialties of the actors (participants) that carry out the processes and procedures that occur during the life cycle of a construction entity.
Table 34 - Organizational Roles
Organizational Roles are the functional positions occupied by the participants, both individuals and groups, that carry out the processes and procedures which occur during the life cycle of a construction entity. Table 34 can be combined with Table 33 – Disciplines, to provide a full classification of each participant in the creation and support of a facility.
Table 35 - Tools
Tools are the resources used to develop the design and construction of a project that do not become a permanent part of the facility, including computer systems, vehicles, scaffolding and all other items needed to execute the processes and procedures relating to the life cycle of a construction entity.
Table 36 - Information
Information is data referenced and utilized during the process of creating and sustaining the built environment.
Table 41 - Materials
Materials are substances used in construction or to manufacture products and other items used in construction. These substances may be raw materials or refined compounds, and are considered subjects of this table irrespective of form.
Table 49 - Properties
Properties are measurable or definable characteristics of construction entities.
