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.

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

This document was prepared by Technical Committee ISO/TC 10, Technical product documentation,
Subcommittee SC 08, Construction documentation.
This third edition cancels and replaces the second edition (ISO 4172:1991), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— validation of normative references;
— provisions of wider levels of drawings;
— The replacement of the term “location drawings” by “general arrangement drawings”.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This standard sets out the requirements for representing prefabricated structures with assembly
drawings. Prefabricated structures are construction components that are more likely to be considered
as products comprising assemblies, rather than traditional components.
The purpose of this standard is to aid with the following aspects
— defining the drawing types and their hierarchy clearly;
— providing the technical rules within each type of drawings;
— giving the guidelines for the application of representation techniques.
Drawings of prefabricated structures need to consider how they collect, demonstrate, and disseminate
product information across all stakeholders, i.e., designers, engineers, manufacturers, and contractors.
Product information must support stakeholders to be able to recognize product definitions, relations,
and other requirements identified within the life cycle. Equal importance should be given to the
drawing of the products using lines, symbols, and other graphic representations, so as to organize the
information on the basis of concepts and relationships. Therefore, this document should be adopted in
coordination with ISO 7519 and other applicable standards.
ISO 7519 provides a method to organize presentation approaches centering a single given object and
therefore provide a complete information hierarchically. Here the object is a wide concept such as a
building, system, assembly, component, or part. Such a delivery method is advanced to regularize the
information stream within the supply chain by specifying a clear scope either for needs or designated
objects, conducting higher-level performances while presenting unambiguous and sufficient data by
using BIM or other CAD applications.
This standard establishes the rules for prefabricated structures following the principles in ISO 7519
whilst maintaining symbolic representation applicable in the built environment sector. Standards
relating to technical product documentation developed by ISO TC 10, as well as BIM standards by TC
59/SC 13, are considered helpful in adopting this standard.
The illustrations included in this document are intended to illustrate the text and/or to provide
examples of the related technical drawing specification. These illustrations are not fully dimensioned
and tolerance, showing only the relevant general principles.

3.1
assembly
set of related components attached to each other
Note 1 to entry: An assembly can be such an aggregation which may perform a systematic function, e.g., a
structural frame, a truss, or a modular container.
Note 2 to entry: Assembly can be a nested form which means that an assembly is possibly consisted of sub-
assemblies.
[SOURCE: ISO 6707-1:2020, 3.3.5.5, modified — Note 1 and 2 to entry have been added.]
3.2
prefabricated structure
structure erected out of prefabricated structural members (3.3)
3.3
structural member
part of a structure intended to resist forces
Note 1 to entry: Note 1 to entry: In this standard a structural member is commonly a component, sometimes an
assembly such as a modular unit or an assembled truss, which is delivered to the construction site as a purpose
part.
