Directives for a Correct Diagnosis

Abstract

A special Working Group, to study and develop standars related to Building Restoration, Rehabilitation and Maintenance, was formed in January 2001 in AENOR (Spanish Association for Codes and Standars) under the management of the Department of Building Construction of the School of Architecture of Madrid (DCTA-UPM). Three groups were organized to deal with different topics: Diagnosis, Techiques and Materials, and Maintenance.
In this paper the differents topics in which the Diagnosis Subgroup is working are described: historical studies, constructive description of the building and building pathology. These will be basic to carry out a correct diagnosis of any type of building, whether it is historic or not. In the development of such topics, the recognizable architectural values are justified as they are prior to the diagnosis stage.
As an example of the subgroup work, several pathology cards are shown which include: longitudinal cracks of mechanical origin in beams of concrete structures, façade closings and claddings, and general symptoms of installation services.
