Abstract. The digitisation projects of architectural heritage are a field of research continuously evolving and updating in parallel to technological innovations that allow to progressively boost the challenges and requirements of geometric and semantic richness of the related digital configuration of results. Among the arduous tasks under observation, there is the increasing need to harmonize and make the spatial and heterogenous information aspects cooperating. This paper focuses on the procedures for structuring an information system based on the as-built modelling strategy applied on a particularly relevant example of reinforced concrete architecture, which presents the bearing structure of the structural elements featured by complex geometries and roofing conceived as ferrocement wavy elements and therefore equally unusual as a construction system. The entire project refers to a conservation plan that involves structural non-destructive investigations that inquiry the state of health of the structures and their seismic performance. The purpose is to structure a parametric system, based on HBIM technology, which enables the archiving of investigations and results in order to strengthen direct spatial reference between geometric elements and structural analysis results, based also on image and range-based surface analyses, in the direction of a digital twin of the architectural complex.
