Building construction - Organization of information about construction works - Part 2: Framework for classification (ISO 12006-2:2015)

ISO 12006-2:2015 defines a framework for the development of built environment classification systems. It identifies a set of recommended classification table titles for a range of information object classes according to particular views, e.g. by form or function, supported by definitions. It shows how the object classes classified in each table are related, as a series of systems and sub-systems, e.g. in a building information model.
ISO 12006-2:2015 does not provide a complete operational classification system, nor does it provide the content of the tables, though it does give examples. It is intended for use by organizations which develop and publish such classification systems and tables, which may vary in detail to suit local needs. However, if this part of ISO 12006 is applied in the development of local classification systems and tables, then harmonization between them will be facilitated.
ISO 12006-2:2015 applies to the complete life cycle of construction works, including briefing, design, documentation, construction, operation and maintenance, and demolition. It applies to both building and civil engineering works, including associated engineering services and landscaping.

Hochbau - Organisation des Austausches von Informationen über die Durchführung von Hoch- und Tiefbauten - Teil 2: Struktur für die Klassifizierung (ISO 12006-2:2015)

Dieser Teil von ISO 12006 definiert eine Struktur für die Entwicklung von Klassifizierungssystemen für die gebaute Umwelt. Er enthält einen Satz von empfohlenen Titeln von Tabellen für eine Reihe von Informationsobjektklassen für die Klassifizierung nach bestimmten Aspekten, z. B. Form oder Funktion, die durch Definitionen unterstützt sind. Er zeigt die Beziehungen zwischen den in jeder Tabelle enthaltenen Objektklassen als Reihe von Systemen und Untersystemen, z. B. in einem Gebäudedatenmodell.
Dieser Teil von ISO 12006 enthält kein vollständiges System für die Klassifizierung von Operationen und keine Tabelleninhalte, auch wenn Beispiele angegeben sind. Er ist zur Anwendung durch Organisationen vorgesehen, die derartige Klassifizierungssysteme und  tabellen erarbeiten und veröffentlichen, deren Details abhängig von örtlichen Bedürfnissen variieren können. Sollte dieser Teil von ISO 12006 jedoch bei der Entwicklung von örtlichen Klassifizierungssystemen und  tabellen angewendet werden, so wird die Harmonisierung der Systeme und Tabellen erleichtert.
Dieser Teil von ISO 12006 gilt für den kompletten Lebenszyklus von Bauwerken einschließlich Projekt-beschreibung, Bemessung und Konstruktion, Dokumentation, Errichtung, Betrieb und Instandhaltung sowie Abriss. Er gilt für den Hoch- und Tiefbau einschließlich der damit verbundenen ingenieurtechnischen Dienstleistungen und Landschaftsgestaltung.

Construction immobilière - Organisation de l'information des travaux de construction - Partie 2: Plan type pour la classification (ISO 12006-2:2015)

La présente partie de l'ISO 12006 définit un cadre pour l'élaboration de systèmes de classification du cadre bâti. Elle identifie un ensemble d'intitulés de tableaux de classification recommandés pour une série de classes d'objets d'information en fonction de points de vue particuliers, par exemple par forme ou fonction, avec l'appui de définitions. Elle montre comment les classes d'objets répertoriées dans chaque tableau sont liées, sous la forme d'une série de systèmes et de sous-systèmes, par exemple dans un modèle d'informations de la construction.
La présente partie de l'ISO 12006 ne fournit pas de système de classification opérationnel complet, ni le contenu des tableaux, bien que des exemples soient donnés. Elle est destinée aux organismes qui élaborent et publient de tels systèmes et tableaux de classification, dont les détails peuvent varier en fonction des besoins locaux. Toutefois, si la présente partie de l'ISO 12006 est appliquée pour l'élaboration des systèmes et des tableaux de classification locaux, cela facilitera alors leur harmonisation mutuelle.
La présente partie de l'ISO 12006 s'applique à l'ensemble du cycle de vie des travaux de construction, comprenant la préparation, la conception, la documentation, la construction, l'exploitation, la maintenance et la démolition. Elle s'applique aux bâtiments et ouvrages de génie civil, y compris les services d'ingénierie et d'aménagement paysager connexes.

Introduction
0.1 Background
This part of ISO 12006 was first produced when there was little international standardization of
classification systems for construction. Now, several national classification systems have been
developed, for example, in North America, Scandinavia, and the UK, that implement the 2001 edition.
Lessons learned in these implementations have been applied in this second edition.
This part of ISO 12006 has also been revised to take into account developments in information technology
(notably building information modelling) and construction procurement (for example, design-build
and design-build-operate). It has been extended and definitions have been refined to better serve all
construction sectors, including building, civil engineering, and even process engineering. However, it
continues to serve traditional information technologies and procurement methods.
A survey conducted as part of the work towards this edition showed that the most widely used
classifications remain work results (mainly for specifications) and elements (mainly for cost analysis).
They are also the most widely varied classification tables not only in their itemization and structure but
also in the range of purposes to which they are put. There are other classifications, potentially just as
important, which are used to a lesser degree, e.g. for construction products and properties.
0.2 The need for standardization
Building information modelling and modern forms of procurement require all these construction
object classes to be used, along with many others. Building information modelling, in particular, is
about exchange of information of all types along the project time line and between participants and
applications. This is also the case for cooperative forms of procurement. For this exchange to be
successful, a complete and consistent approach to construction object classification is required within
the project, and between projects. This part of ISO 12006 is intended to facilitate this exchange.
Information types include geometrical data, functional and technical data, and cost data and
maintenance data. The project timeline runs from inception to eventual demolition. Participants include
clients, designers, authorities, constructors, end users, and operators. Applications include modelling,
specification, product information, and cost information systems. Even now, there is still pressure for
each of these to retain, or even develop, its own classification silo. This is not sustainable.
While national classifications that implement this part are still likely to differ in their detail (for
example, due to differences in construction culture and legislation), mapping between them should be
fairly straightforward. This is because they will be using the same overarching classification framework
and construction object class definitions. This, in turn, will help with international construction project
work (with participants from many countries), and with development of applications intended to be
used internationally.
0.3 The content of this part
This part of ISO 12006 defines a framework for construction-sector classification systems and identifies
a set of recommended classification tables and their titles for a range of construction object classes
according to particular views, supported by definitions.

Part 2:
Framework for classification
1 Scope
This part of ISO 12006 defines a framework for the development of built environment classification
systems. It identifies a set of recommended classification table titles for a range of information object
classes according to particular views, e.g. by form or function, supported by definitions. It shows how
the object classes classified in each table are related, as a series of systems and sub-systems, e.g. in a
building information model.
This part of ISO 12006 does not provide a complete operational classification system, nor does it provide
the content of the tables, though it does give examples. It is intended for use by organizations which
develop and publish such classification systems and tables, which may vary in detail to suit local needs.
However, if this part of ISO 12006 is applied in the development of local classification systems and tables,
then harmonization between them will be facilitated.
This part of ISO 12006 applies to the complete life cycle of construction works, including briefing, design,
documentation, construction, operation and maintenance, and demolition. It applies to both building
and civil engineering works, including associated engineering services and landscaping.

4 Basic principles
4.1 Object and process model
This text is supported by Figure 1.
The starting point for the design of construction complexes and construction entities is a need.
Documentation of user activities and functional requirements is an important part of the information
needed in the construction process. However, classification of user activity is considered outside the
scope of this International Standard.
The different classes in the standard are related in a basic process model which states that a construction
process uses construction resources to achieve construction results. It creates a principal structure
for the classes of greatest interest. The stage of the construction process lifecycle characterizes a
construction process. There are four main types of construction processes: pre-design process, design
process, production process, and maintenance process.
Construction entities enable user activities and functional requirements. They can be aggregated into
construction complexes. Construction entities consist of construction elements which can be made up
of parts in several levels of complexity.
A space is an activity space, a built space, or a construction space. A built space is defined by construction
results. Spaces can have spatial relationships such as ‘contained in’ or ‘adjoining’.
Construction resources comprise construction products, construction aids, construction agents, and
construction information. The difference between a construction resource and a construction result
is a question of its relation to a construction process and not of difference in object class. For example,
construction information may be used as a resource to inform and control a construction process, or
may be the result of such a process itself.
Construction objects have construction properties. Properties are represented as attributes in
construction information.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

Introduction
0.1 Background
This part of ISO 12006 was first produced when there was little international standardization of
classification systems for construction. Now, several national classification systems have been
developed, for example, in North America, Scandinavia, and the UK, that implement the 2001 edition.
Lessons learned in these implementations have been applied in this second edition.
This part of ISO 12006 has also been revised to take into account developments in information technology
(notably building information modelling) and construction procurement (for example, design-build
and design-build-operate). It has been extended and definitions have been refined to better serve all
construction sectors, including building, civil engineering, and even process engineering. However, it
continues to serve traditional information technologies and procurement methods.
A survey conducted as part of the work towards this edition showed that the most widely used
classifications remain work results (mainly for specifications) and elements (mainly for cost analysis).
They are also the most widely varied classification tables not only in their itemization and structure but
also in the range of purposes to which they are put. There are other classifications, potentially just as
important, which are used to a lesser degree, e.g. for construction products and properties.
0.2 The need for standardization
Building information modelling and modern forms of procurement require all these construction
object classes to be used, along with many others. Building information modelling, in particular, is
about exchange of information of all types along the project time line and between participants and
applications. This is also the case for cooperative forms of procurement. For this exchange to be
successful, a complete and consistent approach to construction object classification is required within
the project, and between projects. This part of ISO 12006 is intended to facilitate this exchange.
Information types include geometrical data, functional and technical data, and cost data and
maintenance data. The project timeline runs from inception to eventual demolition. Participants include
clients, designers, authorities, constructors, end users, and operators. Applications include modelling,
specification, product information, and cost information systems. Even now, there is still pressure for
each of these to retain, or even develop, its own classification silo. This is not sustainable.
While national classifications that implement this part are still likely to differ in their detail (for
example, due to differences in construction culture and legislation), mapping between them should be
fairly straightforward. This is because they will be using the same overarching classification framework
and construction object class definitions. This, in turn, will help with international construction project
work (with participants from many countries), and with development of applications intended to be
used internationally.
0.3 The content of this part
This part of ISO 12006 defines a framework for construction-sector classification systems and identifies
a set of recommended classification tables and their titles for a range of construction object classes
according to particular views, supported by definitions.

Part 2:
Framework for classification
1 Scope
This part of ISO 12006 defines a framework for the development of built environment classification
systems. It identifies a set of recommended classification table titles for a range of information object
classes according to particular views, e.g. by form or function, supported by definitions. It shows how
the object classes classified in each table are related, as a series of systems and sub-systems, e.g. in a
building information model.
This part of ISO 12006 does not provide a complete operational classification system, nor does it provide
the content of the tables, though it does give examples. It is intended for use by organizations which
develop and publish such classification systems and tables, which may vary in detail to suit local needs.
However, if this part of ISO 12006 is applied in the development of local classification systems and tables,
then harmonization between them will be facilitated.
This part of ISO 12006 applies to the complete life cycle of construction works, including briefing, design,
documentation, construction, operation and maintenance, and demolition. It applies to both building
and civil engineering works, including associated engineering services and landscaping.

4 Basic principles
4.1 Object and process model
This text is supported by Figure 1.
The starting point for the design of construction complexes and construction entities is a need.
Documentation of user activities and functional requirements is an important part of the information
needed in the construction process. However, classification of user activity is considered outside the
scope of this International Standard.
The different classes in the standard are related in a basic process model which states that a construction
process uses construction resources to achieve construction results. It creates a principal structure
for the classes of greatest interest. The stage of the construction process lifecycle characterizes a
construction process. There are four main types of construction processes: pre-design process, design
process, production process, and maintenance process.
Construction entities enable user activities and functional requirements. They can be aggregated into
construction complexes. Construction entities consist of construction elements which can be made up
of parts in several levels of complexity.
A space is an activity space, a built space, or a construction space. A built space is defined by construction
results. Spaces can have spatial relationships such as ‘contained in’ or ‘adjoining’.
Construction resources comprise construction products, construction aids, construction agents, and
construction information. The difference between a construction resource and a construction result
is a question of its relation to a construction process and not of difference in object class. For example,
construction information may be used as a resource to inform and control a construction process, or
may be the result of such a process itself.
Construction objects have construction properties. Properties are represented as attributes in
construction information.

4.2 Classification and composition
Classification systems may, apart from a level order of specialization (classes and subclasses), also have
a level order of composition, called compositional structuring. See Figure 2.

4.3 Classification (type-of)
The purpose of classifying is to distinguish between objects in a collection based on properties of
interest. Classes are defined by attributes representing the properties of interest.
Initially, the properties common to the whole collection must be determined. The resulting class is
the most general in the classification. Then, the general class may be subdivided into more specialized
classes in several steps based on differences in properties of interest.

---------------------- Page: 16 ----------------------
oSIST prEN ISO 12006-2:2019
ISO 12006-2:2015(E)

The subdivision results in classes that run from the general to the specialized. The classes are ordered
in levels determined by the relation type-of, where specific classes are types of more general classes.
The classified objects are members of the classes.
4.4 Systems and compositional structuring (part-of)
The concept of system is not linked to any specific domain, but is to be used in a broad sense.
In the context of this International Standard, all objects can be seen as systems.
The system approach allows a designer to handle wholes (as distinct from parts). By identifying related
systems, the relationships among these can be determined, and monitored, e.g. to ensure that all systems
operate correctly. Examples of relationships are input to or output from a system to its environment.
EXAMPLE Load-bearing system, roof system, wall system, HVAC system, drainage system, electrical system,
communication system, transportation system, planting system, painting system, hospital system, ecosystem,
landscape system, repair system, management system, educational system, window system, suspension system,
hinge system, fan system, prefabrication system, procurement system.
Systems can consist of sub-systems in different compositional levels. By subdividing or structuring a
system in sub-systems, using part-of relations, large sets of information in a complex design can be
handled in smaller parts. Compositional structuring may, thus, provide an overview of a system, e.g. for
the purpose of understanding, establishing, and modifying. A system of systems brings together a set of
systems for a task that none of the systems can accomplish on its own.
An object is a part if when added to a whole, the whole still remains, e.g. if a brick is added to or subtracted
from a wall system, the whole is still a wall system, or if a wall system is added to a construction entity,
the whole is still a construction ent
