Useful Guidelines for the executive Planning of the Restoration Intervention

. As regards the intervention, the very deliberate choice has been made to grant clear priority to actions connected with conservation, as compared to any other type of intervention, with the objective of assuring the maximum possibility of survival to the heritage's original constituent materials. Conservation, we ought to remind ourselves, should always be taken to mean a calibrated transformation, which has been well planned and reduced to the minimum of interventive steps, both from the quantitative and qualitative points of view, and aimed at the substantial preservation of the heritage. The goal of the intervention will be eliminate all that is manifestly damaging to the heritage, and, at the same time, to add elements that will provide greater solidity and water-resistance to the material constituents of the building. This type of project involves, in order to achieve the conservation objectives, a thorough description of the tasks to perform and the products and tools to be employed in carrying them out. The plan is the result of a painstaking and systematic analysis of the monument, carried out by means of an attentive visual inspection and various surveying activities, together with a preparatory diagnosis of the degradation phenomena observed. In reference to the graphics application chosen, repeating field patterns were assigned to each of the various types of deterioration (both in the legend and in the graphic representation) which correspond to the zones affected. A table was created to complete the diagnosis and to provide a detailed account of the findings. The table takes the form of a clearly laid out range of photographic sample images showing the various types of degradation that can be found - material by material - on the elevations in question. With the goal of providing a more precise idea of the extent of each type of degradation, care was taken to isolate and enclose, within a frame, in detailed macroscopical terms (including measurements), the principal deterioration morphologies affecting the various materials. The presentation is also provided with sketches to show the causes and mechanisms which may have produced - one by one - the forms of deterioration detected; the position and identification of each photographic sample frame is also included in a single, a unified view. The macroscopic diagnosis of the monument did not entirely suffice for the acquisition of a profound understanding of the degenerative state of the heritage, particularly in regard to the more complex issues. The diagnosis, can, however, be considered a point of departure for a future, more detailed scientific investigation, which, on this occasion, for obvious reasons, it was impossible to carry out.
