The research will deal with new methods about project and digital strategies: first starting from digital survey, operated with 3D laser scanner and photogrammetry procedures, allowing, through various operations, coordinated in a workflow to obtain a single point-cloud, derived from the alignment of all scan, to generate a complex 3D model, so called Building Information Model for Heritage (BIM-H).

The present research project aims to investigate and systematize, the new digital restitution strategies of the fortification existing through laser scanning and digital mapping, in particular, on military structures, as well as reflect on the problem of protection and managing this specific kind of built heritage today so far from the motivations that once determined its construction.

Choosing two case studies, belonging to the coastal fortifications system of Northern Sardinia, built in the same historical period, Forte Cappellini and Punta Rossa, analyze the common constructive characters, the relationship with nature and their current state of conservation, going to verify the possibility of sharing methodologies and strategies of appropriate project.

Passing from an isolated and static vision of work files to one that will be shared and dynamic, it will be possible to offer “food for thoughts” in various areas and disciplines related to Architecture, which will be able to interface simultaneously and work in progress, enriching its content and know-how.

The outcome of the study will allow to recognize the emergence of a new strategy of scientific investigation and design able to positively influence the protection and conservation of military architecture of our peninsula, suggesting theoretical and operational guidelines of different nature, often in shorter times and with results almost unimaginable before, allowing for further analysis and developments the same model in future.
