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
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

ISO 6707-4:2021(E)
Introduction
With the growth in the number of international construction projects and the development of the
international market in construction products, there is an increasing need for agreement on a common
language. The objective of the ISO 6707 series is to provide a consistent language for use by the various
professions involved in the construction industry.
ISO 6707-1 defines general terms related to buildings and civil engineering works. This document
establishes preferred terms and concepts related to facility management for buildings and other types
of construction works.
This document is intended as a complement to ISO 41011. Some terms from ISO 41011 of particular
relevance to this document have been reproduced. It is assumed that users will continue to use that
document as reference for facility management terms generally.
For this document, reference is made to existing ISO definitions. Deviations maintain the original
intention, whilst facilitating their interpretation in the context of facility management related to
buildings and civil engineering works.
Consideration has also been given to the way in which electronic processes are being increasingly
employed and how this has an impact on the work of those engaged in facility management.

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
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

ISO/FDIS 6707-4:2021(E)
Introduction
With the growth in the number of international construction projects and the development of the
international market in construction products, there is an increasing need for agreement on a common
language. The objective of the ISO 6707 series is to provide a consistent language for use by the various
professions involved in the construction industry.
ISO 6707-1 defines general terms related to buildings and civil engineering works. This document
establishes preferred terms and concepts related to facility management for buildings and other types
of construction works.
This document is intended as a complement to ISO 41011. Some terms from ISO 41011 of particular
relevance to this document have been reproduced. It is assumed that users will continue to use that
document as reference for facility management terms generally.
For this document, reference is made to existing ISO definitions. Deviations maintain the original
intention, whilst facilitating their interpretation in the context of facility management related to
buildings and civil engineering works.
Consideration has also been given to the way in which electronic processes are being increasingly
employed and how this has an impact on the work of those engaged in facility management.
