The paper evidences the importance of a correct
survey, adjusting new technologies to the historicalarchitectural
needs. Thanks to the laser scanner technology it
is possible to plan the best positions of the instrument in order
to acquire the information of an architecture. Although the
laser is able to register data of the most surfaces of an
architecture, it is subject to different issues that could
compromise a good survey activity. New integrations were
performed in the S. Zenone chapel for acquiring data in

The sinkhole known as 'Pozzo del Merro' possesses unusual, geological and natural features, providing an important opportunity to study the geological and hydrological characteristics of the area, and, at the same time, to preserve an ecosystem inhabited by rare species. The site has been the object of numerous studies carried out by scholars from a wide range of disciplines, but a true morphological survey has not been performed until now due to logistical difficulties that include the lack of adequate measuring positions and the difficulty of establishing a clear view between points.

In Europe, the attention to efficiency and safety of international railway freight transport has grown in recent years and this has drawn attention to the importance of verifying the clearance between vehicle and lining, mostly when different and variable rolling stock types are expected. This work consists of defining an innovative methodology, with the objective of surveying the tunnel structures, verifying the clearance conditions, and designing a retrofitting work if necessary.
