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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)

Introduction
ISO 22040 covers the stages of structural planning, design, execution, use and end-of-life of structures. In
life cycle management (LCM), the natural environment, variable actions, and importance of the structure
should be appropriately considered throughout the period of use of the structure.
This document provides LCM at the execution stage for all kinds of concrete structures or their components.
Execution involves many uncertain factors, with a great deal of information being recorded until
completion. Information obtained during the execution stage is appropriately confirmed and fed back to
subsequent execution processes. This is essential also from the aspect of PDCA (plan-do-check-act) at the
execution stage. Utilization of such information for maintenance of structures and design and execution of
similar structures is also important. Such information is also expected to be utilized for reuse or recycle
of component members and materials at the demolition stage of structures, contributing to mitigation of
environmental burdens.

4 Life cycle management in execution stage
4.1 General
The performance requirements for a concrete structure shall be established based on ISO 2394 and
ISO 19338. The environmental management at the execution stage shall be implemented based on the
ISO 13315 series. The structure shall be constructed to satisfy the performance requirements established
at the structural planning and design stage, while securing safety of execution work, which shall be in
accordance with ISO 22965-2 and ISO 22966. Meanwhile, execution involves many uncertain factors,
requiring consideration of the case where the execution quality does not meet the design preconditions. It is
also necessary to anticipate the possibility that potential defects can impair the durability of the structure
in the future. It is, therefore, crucial to record the information obtained during the execution stage.
The basic management flow chart at execution stage is presented in Figure 1.
This document establishes that the execution information includes not only the execution plan and execution
specification but also the materials used, properties thereof, details of execution, meteorological data, and
quality control records. These pieces of information shall be recorded and stored as information necessary
for future LCM and transferred to the use stage for sufficient maintenance work.
Upon completion or at the beginning of the use of the structure, it shall be confirmed whether the matters
established at the design stage are achieved and whether execution has been appropriately carried out. This
is the first assessment during maintenance work at the use stage. If any defect is found, then repair shall be
conducted as required. The subsequent LCM scenario shall be corrected at this point.

4.2 Indicators for life cycle management
In LCM, indicators necessary for assessing the LCM scenario shall be appropriately established with respect
to the sustainability factors in the social, environmental, and economic aspects. These indicators shall be
calculated based on the LCM period.
Prior to execution, the constructor should ascertain the service life required for the structure and should
formulate execution and inspection plans to achieve the service life, in considerat
