This proposal has been prepared by the working group set up by the Technical Chamber of Greece and aims to provide engineers and associated professionals with a Code of Practice for the Survey and the Design of the Rehabilitation of Monuments and Urban Nuclei. The proposals are based on the experience of the group, experience gained on the Design of the Rehabilitation of Monuments and modest buildings of historical value. The paper contains the main points of the Introduction and the proposed standards concerning Structural Design covering the following aspects: -Structural Survey including Dimensional survey, Damage survey, Historical survey, Environmental survey, Soil survey, Building-materials properties and characteristics. -Appraisal of Structural Adequacy including assessment of causes of existing damage. -Structural Rehabilitation Design. All International conventions referring to the conservation of Monuments have been taken into account in this proposal and the main effort of the group has been to take into account both the special problems inherent in the Structural systems and the need to minimize intervention. Since the working group's member practice in Greece, the special inherent characteristics and features of traditional construction in the Hellenic region have been taken into account and due to the fact that the structural system most commonly found in this region is Structural Masonry, the standards have been drawn up taking this fact into account.
