The ongoing urbanization has led to the emergence of several complex constructions and multi-dimensional property rights. Traditional cadastral procedures cannot meet the demands of this new reality, leading to increased costs and long delays. Exploiting the capabilities of the latest technologies, mobile services (m-services), Building Information Models (BIMs), open-source software (OSS) and the international standard of Land Administration Domain Model (LADM ISO 19152), the development of a reliable, qualitative and affordable solution for the implementation of 3D Cadastres, is feasible. The utilization of crowdsourcing techniques for the implementation of fit-for-purpose 3D cadastral surveys, utilizing the currently available 2D geospatial infrastructure, has already been proved to provide qualitative results. Integrating BIM data with cadastral information derived from crowdsourcing techniques, may significantly speed up the implementation of 3D Cadastres, providing a better visual understanding of 3D property rights. In this paper a LADM-based technical solution for the initial acquisition, registration and representation of 3D crowdsourced cadastral data (re-)using existing BIM and m-services, is developed and presented. A practical experiment is conducted for a multi-storey building in an urban area of Athens, Greece. The main conclusions refer to the usability, the perspectives and the reliability of the proposed framework, are discussed and presented.
