Abstract:
Built Information Modeling (BIM) is quickly becoming a standard in managing and documenting the built world for development and maintenance, but when applied, this solution may be consuming and expensive. The procedure proposed can be considered as an entry level alternative to BIM technology in situation with critical budget and in need to move later towards a more complete BIM solution. In the next future the BIM approach (based on the interoperability of data) will be more present and integrated, becoming a new paradigm in design interventions, maintenance plans as well as being easily accessible via VIM (Virtual Information Modeling) tools. The case study presented focuses on the investigation of the geometric aspects and informative surveys (via 3D laser scanning and photographic acquisition) of the walls of Kyrenia-Girne Castle in North Cyprus. Evolving from the two surveys, a simple procedure was created to allow the insertion of additional punctual information from different means to complement and enrich the geometric modeling, such as type of constructive technique and materials of the walls, colors, static functions, state of conservation and photographs, to get to the final aim of the research which is the walls dating. With this premise it is possible to propose solutions that, starting from digital survey data, can provide rapid and effective information, ensuring results that can be cross-referenced. The use of Autodesk Recap provided the possibility to link photographic images, external links like references, data, PDF files, to specific points within the point cloud. The resulting version of the point cloud is compliant with the use of Autocad, 3D Studio Max and especially in integration with Autodesk Revit; it may influence positively the construction of a full BIM model, exploiting data gathered and linked to the point cloud for the creation of the general models and its families.

Relevance for the conference: A low cost approach to documenting and sharing data from digital survey for research and restoration purposes
Relevance for the session: An alternative approach to organizing data with operators of various skills and abilities
Innovation: Use of available tools and definition of procedures in a yet not well explored and exploited software, with the intent to share it with architects, archaeologists, cultural heritage experts
