Non-destructive testing and historic building information modelling for the structural diagnosis of the church of the society of Jesus in Cusco, Peru

This paper aims at presenting the results of a set of non-destructive tests (NDT) applied to an emblematic stone masonry church and the generation of a 3D parametric model to store and visualise structural diagnosis information following the historic building information modelling (HBIM) framework. Reverse engineering techniques were applied to obtain a precise point cloud of the church. NDT results exposed that the church currently presents several structural anomalies such as cracks, efflorescence, and moisture, among others. In addition, the mechanical characterisation showed that the masonry walls and pillars have an elasticity modulus within the expected range. Furthermore, with the application of operational modal analysis (OMA), it was possible to identify three modes of vibration of the structure. The representation of all the non-geometric information inside the HBIM model plus the generation of a custom plugin allowed the visualisation and adequately managing of the structural diagnosis information of the project.
