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).

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.
