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
The ISO 15686 series on buildings and constructed assets, including service life planning, is an essential
contribution to the development of a policy for service life planning of buildings and constructed assets.
This part of ISO 15686 establishes the basic procedures necessary for the service life planning process
of buildings. However, for this to occur it is considered that an information system is needed. An
information management system suitable for carrying out the service life planning process needs to
meet a number of rigorous requirements including being able to
— capture enough information and support the methods needed to calculate the effect of the
environment (and microclimate) on the building materials and components used,
— define maintenance schedules for different qualities of building materials installed under different
environmental conditions.
— apply life cycle costing methodologies using the captured data to calculate the benefits of using
either high performance materials with little maintenance or lower performance materials with
better maintenance procedures. Procedures need to be able to take ease of replacement and
demolition into account,
— incorporate new knowledge and predictive methods for material performance and maintenance
without affecting methods and data structures that enable calculations based on current knowledge,
— support interoperability between software applications, and
— be used by designers, constructors, owners, operators and demolishers throughout the construction
lifecycle.
Practically, this means applying the technology that is generally being termed Building construction
Information Modelling (BIM) systems. BIM and the use of software applications that enable it is becoming
a normal way of working within the construction industry. It offers significant benefits including the
ability to work with construction components and assemblies as objects that encapsulate both shape
(in the form of geometric information) and other information about performance, delivery, operation
and more. Performance can include information about durability and sustainability metrics. This
offers powerful capabilities for dealing with these key areas of interest at every level from individual
component to constructed facility.
This standard is particularly concerned with the provision of information for service life planning.
It proposes structures for the capture and exchange of service life planning information based on
the Industry Foundation Classes (IFC) standard for information exchange and sharing and on the
Construction Operations Building Information Exchange (COBie) standard.
The standard starts by providing the service life planning context within which it is prepared. Each-
subsequent section covers a stage of the lifecycle of service life information, starting with its measurement
