Implementation and Management of Structural Deformations into Historic Building Information Models.

Building Information Modeling for the conservation and maintenance of architectural and cultural heritage is a great scientific debate nowadays. The creation of an HBIM model allows managing the geometry of the building and exchanging information between the experts involved in the conservation of historic buildings. This paper fosters the creation of an as-built-HBIM containing detailed structural deformations, for which modeling processes with scarce presence in the scientific literature are required. In this sense, two modeling procedures for a structural HBIM Project are proposed for the Pavilion of Carlos V in the Real Alcázar in Seville, Spain. Also, two states of the structural HBIM Project of the Pavilion are geometrically analyzed: 1) theoretical-HBIM, without deformations, generated by using measurements from documentary sources, and 2) as-built-HBIM created from point clouds from terrestrial laser scanning and photogrammetry. The results of this paper show significant structural discrepancies in the geometry between both HBIM Projects. [ABSTRACT FROM AUTHOR]
