The investigations that are made on a building for conservation purposes need an importantwork that is transcribed in a variety of numerical and printed data: surveying data andscientific imagery, damage mapping, photographic collections, historical archives, physicaland chemical data etc. Given the difficulty to collect, compare, analyse and validate dataprior to restoration, the approach we present aims to mobilize various disciplines(architecture, conservation, mechanics, and computer sciences) to define a novelinformation processing chain including metric surveys, analysis of surfaces, geometricmodels of structures, heterogeneous documentary sources management, temporal data, etc.By the way of MONUMENTUM project which is an on-going research project (2013-2017) funded by ANR (French National Agency for Research), we are designing anddeveloping an open and expandible web platform for the capitalisation and the managementof knowledge needed for the understanding and analysis of degradation phenomenaaffecting historic buildings. This objective requires the definition of a common andcontinuous process that establish a technological and conceptual interconnection betweenthe stages of 3D digitization, semantic annotation and structuring of the geometric model(including multi-layers analysis of surfaces), characterisation of the state of the buildingand management of restoration actions. Based on three case studies that presentconservation issues on stones (Castle of Chambord and Caromb’s church in France) andwall paintings (Notre-Dames des Fontaines’ chapel in France), it concerns the image-basedmodellingof architectural heritage, the development of a 3D information system for the management of conservation data and also a numerical modelling tool (FEM-DEM) for thephysical and structural analysis.
