Abstract
Abstract. Relevant cultural heritage buildings have been subject to numerous maintenance interventions over the years. Building Information Modelling (BIM) technology is already part of the construction industry especially in the design phase and is considered as a very useful tool. From a survey with an Unmanned Aerial Vehicles (UAVs), using photogrammetry is possible to determine characteristics such as sizes and shape object, volumes, areas, distances, elevations and furthermore the reconstruction of high-quality model. A whole integration between the two methods will be a “game changer” for the construction sector. Moreover, old buildings have complex architecture, with high and particular details that today's BIM software’s aren’t able to perfectly represent today.In this paper, we present a methodology to integrate into BIM environment a 3D reconstruction as-built drawings of an old church using photogrammetric techniques, in order to find a solution to reproduce the complex details present in ancient buildings.

Relevant cultural heritage buildings have been subject to numerous maintenance interventions over the years
The use of Building Information Modelling (BIM) for documentation and management of historical building presents different advantages: archive of historical documents, single access point for all data, support for technical analysis, support for scheduling maintenance interventions, promotion of cultural heritage, through the sharing of the model on the web or the realization of virtual or augmented reality applications, monitoring of degradation, simulation of response to catastrophic events etc
It is well suited to the modeling of point clouds generated by geomatics procedures such as, for example, photogrammetry from Unmanned Aerial Vehicles (UAVs)
Summary
Relevant cultural heritage buildings have been subject to numerous maintenance interventions over the years. A process originally conceived for new buildings can represent a valid tool for existing buildings with the correct adaptation, especially in a historical period with particular focus on restoration In this perspective the possibility to use the advantages of the information management guaranteed by the BIM, in the context of existing constructions became strategic. Applying BIM methodologies to existing buildings, we can manage in a coherent and coordinated way all the phases of the building life, according to a life-cycle approach In this context, it is essential to resort to the peculiarities of BIM for the existing, for which the documentation of places, technologies and materials is increasingly important for the preservation of historical and cultural heritage. Another approach (defined Scan-to-BIM) according to which the geometric components derived from the survey are obtained locally without resorting to libraries of objects already precompiled
