Rilievo laser scanner 3D per l'analisi morfologica e il monitoraggio strutturale di alcuni ambienti inseriti nel progetto di ampliamento del complesso mussale degli Uffizi a Firenze

The article presents the research activities conducted on several rooms included into the extension project of the Grandi Uffizi Museum. The research work addresses to how define accurate survey methods for monitoring the static performances and plastic deformations of the structures. The research, strongly supported by the heads of the construction works, has helped the technical reconnaissance operations on these rooms, subjected to structural reinforcements and safety measures. To achieve compliant results in line with the project requirements of the construction site it has been necessary to identify the most appropriate graphic representation methods. The main 3D laser scanner survey activities have been accompanied by specific experiences of photomodeling and intensive photographic documentation campaigns. The post production and data processing steps have produced a substantial documentation of graphic materials as floor plans, detailed sections, with the elaboration of wire frame vector drawings and ortho-photo reconstructions, 3D models for the simulation of the static performances and plastic deformations with the overlapping and comparison of the different investigation steps by implementing the reverse engineering processes. The opportunity to support the construction site from 2010 to the present, improving these methods has contributed to the deepening of detection and representation techniques for the definition of operational methods characterized by a high metrical reliability with a detailed data post production results, extremely recommended for supporting sophisticated construction sites as the Grandi Uffizi represents.
