ISO/CD 22040-3

Abstract

The proposed document provides the life cycle management of concrete structures particularly focusing on the execution stage on the basis of the framework and general principles specified by ISO 22040. This document is applicable to not only newly constructed structures but also existing structures when their life cycle is restarted. This document specifies on how performance requirements should be considered at the execution stage and also how the basic LCM scenario should be updated. Management items at the execution stage are clearly defined and information that may be fed back to the design stage and be transferred to the use stage is described.
