Abstract. The paper presents the case study of the survey of the sail vaults of the main building of the Forest Research Institute in Dehradun. The building has been acquired with photogrammetric and laser scanner techniques during the Ground Based 3D Modelling (Photogrammetry and TLS) tutorial, at the ISPRS TC V Mid-term Symposium held in Dehradun, India in November 2018. The acquired data was then used for a structural evaluation of masonry vaults. The 3D model, built using the point cloud data, has been used in an open source finite element analysis software to develop a numerical model and comparative analyses have been carried out. The objective of numerical analysis is assessing both the benefits of structural meshes generated directly from point cloud data and the structural behaviour of the masonry vaults.
