Types of Interventions on Historical Monuments, Approached in the Context of Their Conceptual and Content Precision

The current investigation focuses on a particular type of buildings – existing properties, unclassified and classified as historical monuments, with an emphasis on the latter. From the perspective of protecting and enhancing their heritage component, of respecting quality requirements in construction, the issue of intervention works on this type of edifices is analyzed. At all stages of an intervention, starting with the beginning of the design, a single linguistic code becomes necessary as support for the exchange of information, cooperation, communication at the level of the teams of specialists and related stakeholders. Interventions involve a complex activity with multi-, inter- and transdisciplinary participation, where often routine gives way to innovative approaches or high skills prerequisites, and where uncertainties – especially in the early stages of design – are much more numerous and extensive than in the case of projects for new buildings or on existing unclassified buildings. Here, the architect’s missions and their relevance are configured sui generis, considering the specific character of the project, the type of interventions aimed for, the limitations, conditions and alternative measures imposed by the requirements of preserving the cultural attributes. From the perspective of the defining notes of a specialized language, in this paper, we analyzed the terms that define the variety of interventions on existing buildings and which are materialized in their definitions and classifications. We studied the extent to which, through the definitions and classifications assigned, the various types of interventions included in the specific legislation of immovable cultural heritage and that of civil buildings in general, in other documents and specialized studies, comply with these demands, the difficulties encountered and their nature, possible complementary alternatives with a remedial role. The paper concludes by suggesting potential areas of improvements on this topic and with proposals for future investigations.
