Geomatic Data Turned Into BIM for the Preservation of a Multicultural Building

Disseminating detailed and accessible information about the built heritage is fundamental to help understand the value and meaning of that heritage to society. To this end, the use of historic BIM (HBIM) is an emerging technology that enables engineers and relevant practitioners to understand, document and virtually reconstruct the heritage monument. This paper explores the effectiveness of the implementation of BIM with a practical application of the Sarlidje Palace Hotel, a listed building constructed circa 1909 on the island of Lesvos, Greece. Detailed geometric documentation using surveying and laser scanning was performed to obtain the essential spatial information. The 3D model was created within the Building Information Model (BIM) using collected data and existing CAD plans. The great complexity of the building required the creation of several new families besides the existing BIM Families. The BIM also allowed the modelling of the pathology of the building, which enables further understanding of the construction and provides a guide for interventions.
