How to exploit BIM/IFC for 3D registration of ownership rights in multi-storey buildings: an evidence from Turkey
No full textThe condominium rights, which is a special ownership type that can only exist in the buildings that have an occupancy permit, are needed to be examined and depicted as three-dimensional (3D) in order to prevent misinterpretations and disputes regarding Rights, Restrictions, and Responsibilities (RRRs). This paper, therefore, aims to provide the model that extends the Industry Foundation Classes (IFC) schema by referencing Land Administration Domain Model (LADM) in the sense of reusing the Building Information Modeling (BIM)/IFC model of the building for 3D registration of condominium rights in Turkey. The results of the study show that there is a solid potential to benefit from BIM/IFC model in order for both 3D representation of the ownership rights in the multi-storey buildings and obtaining the semantics of the condominiums in terms of wide ranges of attributes such as area, volume, land share, and RRRs.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.GIS Technologi
3D modelling of subsurface legal spaces and boundaries for 3D land administration
No full text<p>The increasing trend of urbanization results in various problems regarding enabling the livable cities such as traffic congestion, environmental pollution, and inadequate disaster preparedness. These problems are considerably related to deficiencies in the aboveground usable areas that can be exploited for the development of urban areas. Underground development is one of the strong solutions to cope with the aforementioned problems. The holistic planning of underground space is an important factor in ensuring the efficient use of underground space. Land administration that deals with the cadastral rights, restrictions, and responsibilities (RRRs) on the surface and subsurface is highly significant in the context of planning the underground space. By nature, there is a need for three-dimensional (3D) ownership information below the surface in order to carry out the analyses within planning studies regarding different aspects such as the existing subsurface structure and environmental impacts. This paper therefore enriches the core data model of the CityJSON standard such that it allows for 3D modelling of legal spaces and boundaries in the subsurface. It presents the usability of the proposed extension by visualizing the underground cadastral RRRs in 3D through the created and validated CityJSON file based on this extension. The practical opportunity arising from the use of CityJSON files derived from the developed extension is demonstrated. Different case studies are presented including the compliance checking regarding the designed underground tunnel within building permitting. The results of this study show that integrated 3D land administration including subsurface can contribute to the facilitation of the overarching planning of underground space.</p>
The Role of Open Standards in Digital Building Permitting, 3D Registration of Condominium, and Update of 3D City Models
No full textDigitalization is being adopted in many public services to increase the efficiencies of the required operations. Regarding this, there is an important interest in digitalizing the current building permit procedures since most of the buildings are designed digitally and as three-dimensional (3D). In addition, several countries are making an effort to realize the transition from two-dimensional (2D) cadastre to 3D cadastre. This is because 2D delineation of the legal rights may remain incapable to reflect the reality with respect to property ownership in multipartite buildings. The 3D city models should also be kept updated to effectively manage the occasions (e.g. natural disasters) and services (e.g. waterworks) in the living areas. In this sense, the open data standards (e.g. CityGML and Industry Foundation Classes (IFC)) have a vital role to enable interoperability between different domains such as Architecture, Engineering, and Construction (AEC) and Land Administration (LA). In this context, this chapter aims to show the current situation and opportunities on how to efficaciously benefit from open data standards for three significant issues. The issues can be listed as, 1) digitalizing the building permit procedures, 2) registering the condominium as 3D, and 3) updating the 3D city models. The examination in the chapter concerns the cases for Turkey
Unveiling the actual progress of Digital Building Permit: Getting awareness through a critical state of the art review
No full textGrowing interest is awarded to the digitalization of the building permitting use case and many works are developed about the topic. However, the subject is very complex and many aspects are usually tackled separately, making it very hard for traditional literature reviews to grasp the actual progress in the overall topic. This paper unveils the detailed state of the art in Digital Building Permitting (DBP) by critically analysing the literature by means of a set of coding tags (research progress, implementation, affected DBP workflow steps, ambitions addressed) assigned by a multidisciplinary team. The executed research shows that the mainly addressed aspects of the digitalization of building permit process are the technologies to check the compliance of design proposals against regulations, followed by the digitalization of regulations. Improvable aspects identified in the entire building permit system are instead e.g. the involvement of officers, scalability of solutions and interoperability of data, intended both as data validation and as integration of geospatial data with building models.Urban Data Scienc
DEVELOPMENT OF 3D WEB GIS APPLICATION WITH OPEN SOURCE LIBRARY
No full textToday, thanks to the internet connection, the borders are disappearing and accessing information is more comfortable. Instead of desktop applications, number of web-based applications which can be seen instant changes by all users are increasing day by day. The diversity of web-based applications that are currently used in presenting spatial information to users is also spreading. Using open source libraries, developers can develop web applications for their own purposes. Three dimensional (3D) visualization on web is a commonly used approach in geographic information systems (GIS) applications. In this article, it is aimed to develop a 3D web application using open source library. Vector data layers containing attribute data on global, country and city levels are visualized on web application. The raster data layers produced in the most suitable site selection and mapping of land valuation process results are also visualized on the web application in three dimensional. It is pointed that the output products obtained from different studies can be accessed and visualized through the web browser without installing an additional program or add-ons on the users' computers
3D Registration of Apartment Rights Using BIM/IFC: Comparing the Cases of the Netherlands, Saudi Arabia, and Turkey
No full textΤhe built environment has a vast and ever-growing number of complex and multi-layered buildings and other structures. The number of those is growing because of the increasing pressure on the limited space in cities. It is important to note that different professional sectors are involved in the realization of a new building. These sectors are mainly the Architecture, Engineering, Construction, and Owner Operator (AECOO), and land administration, which covers the cadastral registration, spatial or zoning plans, as well as property valuation. Noteworthy to mention at this point is, that today the subdivision plans regarding apartment rights in buildings are to be provided on the floor plans as submitted with the building/construction permit request. These plans show the apartment boundaries as twodimensional (2D) representations, which are insufficient to clearly and completely describe the ownership rights in multi-storey buildings. What is more, the building parts obtained from 2D representations are also inadequate to estimate the valuation of these apartments in both taxation and selling/buying processes. Considering that digitalization and consequently digital data are becoming more and more the norm in the AECOO industry, including the building permit requests, there is an opportunity to exploit Building Information Model (BIM), specifically Industry Foundation Classes (IFC), in the registration of apartment rights in three-dimensional (3D) representations. To investigate the opportunity, this study will further analyze the cases of the Netherlands, Saudi Arabia, and Turkey by revealing the similarities and discrepancies with respect to the registration of apartment rights in terms of legislative basis and current practice and extrapolating the current 2D practices into fully 3D representations. In earlier work, ISO19152 LADM-based models for the 3D building legal spaces have been developed and are related to BIM/IFC. The main objective of the study is to highlight the possibility of providing an internationally standardized modeling specification for 3D registration of legal rights within buildings, based on the earlier detected information model overlaps. What is more, it is expected to increase the awareness in other sectors than land administration with regards to legal spaces in the buildings. Finally, this study endeavors to provide concrete guidelines for the other sectors, most specifically the Architects, regarding the type of information that BIM/IFC models should have, in order to facilitate the 3D registration of apartment rights.Digital Technologie
