This part of ISO 12006 defines a framework and a set of recommended table titles supported by definitions, but not the detailed content of these tables. It is intended for use by organizations which develop and publish classification systems and tables on a national or regional basis. This part of ISO 12006 applies to the complete life cycle of construction works, including design, production, maintenance and demolition, and to both building and civil engineering. It identifies classes for the organization of information and indicates how these classes are related. This part of ISO 12006 lists the tables which are recommended to be developed and used to classify the members of each class according to particular views or principles of specialization and gives examples of entries which might occur in these tables. It does not provide a complete operational classification system. Classification tables may vary in detail to suit local needs.
