An adequate diagnosis and critical survey are the basic initial steps to establish the state of conservation of a property or heritage complex. Through the exhaustive collection of antecedents in the field, laboratory analysis and historical studies, the objective parameters are obtained for the development of a future restoration or intervention project, and for deciding heritage protection measures.
