Abstract
The project proposal is based on the contextual and technological origins of BIM (Building Information Modelling) and GIS (Geographic Information System). It explores the data and technological integration and upgrading of geodetic data into three dimensions (3D). Upgrading and connecting geodetic data with BIM is termed by the European association EuroSDR (European Spatial Data Research) as GeoBIM. The research problem arises from the traditional role of geodesy, which collects real estate data, public infrastructure and topography in 2D, 2.5D and 2D+1D, where altitude is only an object attribute. Exceptionally, geodetic data sometimes are in 3D form, but with low level of detail (Lod, Level of Detail). In the case of BIM concept, which is increasingly used by modern construction experts in the whole process of construction and maintenance, 3D data with a high degree of detail is one of the fundamental requirements of the recording of the built objects. In this case, BIM allows you to monitor the object in time (4D), with costs (5D) and with the data about management and maintenance (6D/7D), which comprises a full life cycle of the object. It is therefore necessary to investigate the format of the upgrade or reorganization of geodetic data and their reconciliation with the BIM concept, which means a merger and data transfer from GIS to BIM and vice versa. Geodetic data thus become more useful for the construction profession, and detailed construction data from BIM can serve to maintain and complete geodetic databases. The aim of the project is to research and test the concept of GeoBIM, from the aspect of technology and organization of data acquisition, geometric and topological adjustments, and legislative frameworks. Taking into account the responsibilities and tasks of the client and the expected cost of the adjustment process, the key is to upgrade geodetic data to 3D form, where it is reasonable. The results of the research will, inter alia, give an evaluation of the scope of data and technological adjustments for integration with the BIM concept, the proposal for guidelines for the contracting authority and the results of the pilot design for the cadastre of buildings (KB), topography and public infrastructure (PI). The project will be divided into 5 work packages (WP) with total of 15 activities: WP 1: Areas of GeoBIM design, WP 2: Methodology for adjusting geodetic data and processes - support to the concept of GeoBIM, WP 3: Test upgrade of geodetic data, WP 4: Evaluation of results with suggestions, WP 5: Dissemination of project results. In the first WP, the definitions, purpose and current use of GeoBIM will be analyzed. The use of KB, PI and topography datasets will be researched, the additional usage options will be described, and the legislative framework for implementation will be examined. The status of introducing the concept of GeoBIM in Europe and the results of the recently completed projects of GeoBIM within EuroSDR will be described. In the second WP, a methodology for adjusting geodetic data and processes will be created. Further research will study the upgrade of geodetic data for greater interoperability with BIM, the transformation of data from BIM of newly built objects for modernizing geodetic collections and the tools for upgrading geodetic data models. In the third WP, two tests of geodetic data will be carried out, namely the collections of PI and KB, by upgrading in the 3D structure with the option to transfer data into the BIM environment. In the fourth WP, the geodetic data and technologies for upgrading will be evaluated in the concept of GeoBIM, with the impact on the organization of the geodetic service. The guidelines for support of BIM will be developed. The evaluation of legal bases will be given. In the fifth WP, dissemination of results will be performed by reporting to the client and the presentation to the professional public.
