Abstract

Abstract. Baroque architecture presents considerable morphological complexities relating to structural systems, distributive characteristics, and decorative elements. Palazzo Carignano in Turin, designed by Guarino Guarini from 1679, is a quintessential example of the period. The need to comply with public works regulations, monitor the state of conservation, and document the building required to plan new integrated digital surveys and create HBIM models. The workflow developed combines integrated digital surveying methodology with HBIM modeling process, dedicated to both the structural and architectural systems, as well as the decorative elements. The Level of Accuracy (LOA), a control parameter for surveying and modeling, is central to connecting the two phases of the process and represents one of the main challenges of the research.
