Historical and precious buildings’ restoration work and structural consolidation s is one of Razzetti e Bosazza’s specialties. The execution of restoration, preservation or simple maintenance work, is becoming more and more an extremely specialised process. This is why fully qualified personnel, continuous professional trainings and new technologies are needed, always entirely abiding by the architectural and environmental values and without altering the buildings’ nature. For restoration work the first step is an initial fact-finding phase, which includes a preliminary study of the object of interest and its constitutive elements. The following phases are those of pre cleaning and, if necessary, pre consolidation, to then move to the proper cleaning, removal of possible not compatible works and integrations; the last phases relate to consolidation and final protection application. Restoration projects are fully documented and produced according to the authority’s directions.
