The frescoes, the statues and the facades with their heavy doors are the most admired works of art in historical structures. Dottor dedicates the complexity of its survey techniques and great specialisation to them that each high-value intervention requires.
Historical research on the creator of the work and laboratory analysis aimed at establishing the chemical composition of the materials and the degree of conservation of the building are therefore seen to be fundamentally important.

The choices made regarding the different phases of the project are born out of the in-house and external people who are involved talking to each other.
The decisions agreed upon are a safeguard of quality.
