Peshawa Mohammed is a PhD researcher at Technology University Dublin. With over a decade of experience in the geospatial and construction sector, he has acquired expertise in utilizing various geospatial surveying tools and techniques to enhance digitalization in construction projects. His enthusiasm for digitalization has driven him to pursue a PhD, aiming to harness the potential of integrating BIM with geospatial data. Presently, his research revolves around the integration of Building Information Modeling (BIM) and geospatial data to develop Ireland's 3D Land Administration Systems (LAS), thereby fostering more efficient urban development. Moreover, his research extends to serve as a foundation for creating digital twins of the cities and achieving the smart city goal.
What to expect during the event
Over the past two decades, rapid urbanization and increasing number of high-rise buildings and complex infrastructures in urban areas have revealed the limitations of conventional two-dimensional (2D) cadastral systems in accurately representing these areas and have also shown the need for an alternative three-dimensional (3D) system. The goal of 3D cadastres is to register, manage, and present the spatial attributes of volumetric legal entities in a 3D digital information environment. The use of the digital 3D models facilitates the transition from 2D to 3D cadastre. 3D digital models are usually created in different environments for various purposes. Among the 3D models, Building Information Modelling (BIM), and, specifically the Industry Foundation Classes (IFC), provides powerful tools for modelling the physical and legal aspects of singular urban structures. Despite its effectiveness in modelling building structures, BIM technology has limitations in capturing the topological relationships between buildings at a city level. As a result, performing spatial inquiries and analyses on BIM models for cadastral purposes can be challenging. Geographic Information Systems (GIS), and specially CityGML format, provide efficient tools for creating 3D models that can be utilized to address the topological relations and conduct spatial analysis at the city scale. To address these shortcomings in BIM models, they must be integrated with or converted into GIS models. Integrating BIM and GIS models GIS has the potential to support a transition to 3D cadastral systems and to move a step forward towards achieving smart city ambition
