Buildings and civil engineering works — Modular coordination — Module
This document establishes the values of basic module, multimodules for horizontal coordinating dimensions and sub-modular increments for use in modular coordination of buildings. This document also specifies preferred vertical modular dimensions, series of preferred multimodular sizes for horizontal dimensions for all types in accordance with general principles and rules for modular coordination.

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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 59, Buildings and civil engineering works.
This first edition cancels and replaces ISO 1006:1983, ISO 1040:1983, ISO 6512:1982, ISO 6513:1982
and ISO 6514:1982, which have now been merged into one document with a new logical structuring.
There is no technical change compared with the previous versions.
Any feedback or questions on this document should be directed to the user’s national standards body. A
