摘要：Operative interventions are frequently required in the field of estimation in the case of real estate that have exhausted their original function but that can be redesigned or adapted to accommodate new functions and new uses. For example, there are urban buildings of the old town center with property unit in size and type not cheaper, often completely lacking in modern technological systems such as lift, heating, air conditioning, etc. Obviously it is hardly necessary to point out that these technical problems of estimation are here only in reference to the cases of destination allowed and in the full compliance with the standards of urban planning tools in place.
