The ongoing rapid urbanization has led to the emerge of several complex infrastructures distinguished by multi-dimensional and overlapping property rights. The option of integrating BIM data into LA, aligned with international standards and able to handle the three-dimensional (3D) aspect of cadastral objects utilizing contemporary technologies, may be of a great importance. The main objective of this paper is to investigate the potential integration of the Building Information Model (BIM) and the Industry Foundation Classes (IFC) standard, with the international standard of Land Administration Domain Model (LADM ISO 19152 2012), in order to provide a unified solution for the registration and visualization of 3D spatial and sematic information regarding the complex Rights, Restrictions and Responsibilities (RRR) in the new complex constructions. The proposed solution aims to exploit the available 2D plans for the generation of BIMs; and rely on international LADM's constructional guidelines to provide a standardized cadastral database harmonized with the national Greek cadastral and the legal framework and aligned with the current Greek building code. The proposed framework is tested for two multi-storey buildings. The first results are promising constituting an important tool, for the implementation of 3D cadastres. |

In this paper, the potential linkage between the BIM, the LADM, and crowdsourcing techniques is investigated in order to provide an effective technical solution for the integration of large new constructions into 3D crowdsourced cadastral surveys.

Gkeli, Maria; Potsiou, Chryssy; Ioannidis, Charalabos BIM data as Input to 3D Crowdsourced Cadastral Surveying-Potential and Perspectives Proceedings Article In: 2021. Abstract | Links | BibTeX | Tags: 3D cadastre, BIM, Crowdsourcing, Land administration @inproceedings{nokey,So far traditional procedures have often led to increased costs and long delays in the 2D cadastral surveying procedures, making the completion of first registration difficult or even impossible for many countries. In the meantime, the ongoing urbanization has led to the construction of complex buildings with multi-dimensional property rights even in countries with poor and incomplete 2D land administration systems (LAS). This new urban reality though, requires the establishment of modern 3D LAS to protect and secure property Rights, Restrictions and Responsibilities (RRRs) within the three-dimensional environment. Fortunately, crowdsourcing and VGI have recently claimed a critical role as a reliable methodology with an increased potential for affordable and fast systematic registration of both 2D and 3D cadastral data. It has also become clear that a nationwide cadastral system may be comprised of various datasets of varying geometric accuracies integrated together in a fit-for-purpose whole. In the meantime, many cities, regardless of the progress in establishing good land administration systems, are mapped in 3D at various levels of detail and have complex buildings designed, constructed and managed by Building Information Modeling (BIM). Linking cadastral information to the 3D digital representations of the man-made environment could be a promising approach in order to define, declare and visualize the complex 3D cadastral space units. The integration of geospatial information derived from existing BIM with the LAS and the use of crowdsourcing methodology to identify the 3D cadastral objects and declare related rights and other necessary information, may significantly speed up the implementation of multipurpose 3D LAS. Utilizing the Information and Communication Technology (ICT) tools, low-cost equipment, crowdsourcing techniques, web services, open-source software and BIM, the development of a reliable, qualitative and affordable solution for the initial implementation of a 3D cadastre is feasible. This research focuses on how BIM information and crowdsourcing techniques can be combined together to improve the compilation process of a 3D cadastre. The main objective is to investigate and discuss how these domains may interact and cooperate to serve the needs of the systematic 3D Cadastral registration. An innovative 3D crowdsourced cadastral procedure which will also integrate available BIM data is designed, tested and evaluated, aiming to save time and funds and provide a solution for the initial registration and visualization of 3D cadastral data. An open-sourced web application for the visualization and manipulation of BIM data is developed and tested. The user of the application is able to zoom in and out of the scene, make 3D measurements, create vertical and horizontal slices of the building in order to reveal hidden entities, helping him/her to recognize and identify each property unit, and finally insert all the necessary cadastral information, updating the system with new data.

Abstract | Links | BibTeX | Tags: BIM, Greece, Policies, Public sector, Task group @article{Bakogiannis2020,The construction sector is of strategic importance for the European Commission. This is the reason why there is a special interest in the development of this sector which is attempting to transform into a more sustainable one in order to face various challenges. In this context, European Directive 2014/24/EU brings to the foreground of the European institutional framework the term building information modelling (BIM), that it is widely used in many countries across Europe. In Greece, the situation seems to be different, not only because it has not been applied in practice but also because of some special features of the way the construction sector functions. This paper presents the BIM use-level in Greece and the way with which it could be better integrated in the construction sector. Through this review we make a brief assessment of the strategy developed in order for the BIM to be integrated in Greek building procedures. Furthermore, we focus on specific issues, like the extended informal housing phenomenon, and on factors that cannot easily be standardized that create problems in BIM use. Finally, through an initial market analysis we underline the role of academic institutions for integrating BIM across Greece. |
