Abstract. There has been a growing interest in integrating vegetation into the built environment in order to ameliorate the negative effects of increasing urbanisation. In Singapore, government policies encourage the inclusion of skyrise greenery into new and existing buildings. To further streamline workflows, statutory BIM (Building Information Modelling) submissions in architecture, engineering and construction (AEC) industries have been mandated. However, landscape plans are still excluded from these BIM submissions due to the lack of a centralised vegetation database and the absence of a standardised BIM format for landscape architectural submissions. This paper presents a streamlined methodology for creating and using a centralised vegetation library for landscape architects. The workflow leverages off the Industry Foundation Classes (IFC) standard for data exchange regardless of the BIM authoring software used and provides a framework of four operational modules: an expandable and low-maintenance species-level vegetation library, a BIM authoring workflow that allows inclusion of vegetation objects, an IFC interface, and a lightweight 3D vegetation model generator. This paper also showcases a use-case of embedding information-enriched 3D vegetation objects into a simulated landscape plan. The proposed workflow, when adopted in AEC industries, will enable governing agencies to track diverse greening efforts by the industry and to potentially include other measurements such as cooling performance or maintainability.

It is incontrovertible that an exchange of files is essentially required at several stages of the workflow in the architecture, engineering, and construction (AEC) industry. Therefore, investigating and detecting the capabilities/inabilities of building information modeling (BIM) software packages with respect to interoperability can be informative to stakeholders who exchange data between various BIM packages. The work presented in this paper includes a discussion on the interoperability of different software platforms commonly used in the AEC industry. Although, in theory, flawless interoperability of some types of files between different BIM platforms is ensured, in practical applications, this is not always the case. Hence, this research aims to identify faults in data exchange by assessing different possible scenarios where a sample Industry Foundation Classes (IFC) four-dimensions (4D) BIM model and related Gantt charts are exchanged. Throughout the interoperability analysis of both IFC file and Gantt charts, the following checks were carried out: geometrical and nongeometrical information exchange through IFC files, 4D information correct readability, and presence of missing schedule information in Gantt charts after their import/export procedure. The results show that interoperability between the analyzed platforms is not always ensured, providing useful insight into realistic scenarios.

The Difference

Abstract. The integration of Geographic Information System (GIS) and the Building Information Modeling (BIM) referred to as the merging of the two systems for the purpose of data interoperability. The need to share information between the two systems is what motivated the integration process purposely for geospatial analysis. This can be achieved through their data exchange formats such as; City Markup Language (CityGML) and Industry Foundation Classes (IFC). The formats are the two most prominent key schemas of GIS and BIM systems respectively. The integration is a step towards information exchange or sharing (data interoperability) between the two systems. The selection of the two most prominent data exchange formats is as a result of their widespread applications in the GIS and BIM domains. However, the differences in geometric and the semantics information hinders data interoperability (information sharing) between GIS and BIM. Also, coupled with the difference in schema structure and the level of information richness between IFC and CityGML. This paper, propose a geometry transformation process that can be used to extract and transform IFC building objects to that of CityGML building objects to enable 3D model design and constructed using BIM tool to be easily reused in 3D GIS applications which will be able to support the CityGML model format. Where the geometric information will be extracted using the IFC tree-structure (hierarchy) and transformed to destination CityGML.

<p><strong>Abstract.</strong> Modern cities pay particular attention to upscale their infrastructure systems in order to improve the every-day life of their citizens and lead the way towards a more sustainable environment. As part of this, they invest extensive funds in large infrastructure projects which are challenging to deliver as they require an e efficient communication among different professions, in order to share information efficiently throughout the lifecycle of the project, thus highlighting the importance of standardization to maintain consistency and integrity during data exchange. Building Information Modelling (BIM) aims to facilitate the above-mentioned requirements by describing the life-cycle of the project and Industry Foundation Classes (IFC) is the Standard for BIM that enables an efficient storage, management, exchange and visualization of information. However, there are two important challenges that need to be addressed: (i) IFC focuses particularly on buildings and provides limited support for infrastructure elements and (ii) the information exchange aims to describe mostly the construction phase; highlighting the lack of classes that refer to the operation and maintenance phase. Within this context, this paper proposes the extension of Industry Foundation Classes (IFC) for Asset Management in Infrastructure. A method is developed based on a case study of three highway entities: (i) retaining wall, (ii) gantry and (iii) bridge and a conceptual extension is presented. The results are further discussed and recommendations regarding future research fields are proposed.</p>

This research investigates the issues of authoring reusable BIM components that can be delivered across multiple platforms. A key constraint in the uptake of Building Information Modelling (BIM) technology is interoperability, the ability to accurately and automatically share and exchange data. This has been addressed by the creation of a system of standards; Industry Foundation Classes (Ifcs). Recognising the importance of Ifc standards, the promoters of many proprietary BIM software platforms generally claim that their products support them fully. This has been challenged, and the reported work has aimed to test these assertions. A simple test model was constructed to represent the various geometries that are encountered, which were then expressed in Ifc files. Fourteen commonly-used BIM software tools were subjected to tests in which the range of geometries within the test model was imported into each tool in Ifc format. A simple visual analysis of the outcomes showed a dramatic failure to process the geometries as they were intended. The results of the study indicate that the current commercial BIM authoring tools, whilst being technically capable of providing support for the required component geometric representations, are constrained from doing so by their conversion interfaces from Ifc geometries. The practical implications of this are considerable, and could result in the possibility of serious errors within designs for construction projects. This is particularly relevant in the case of the BIM library components that are currently being authored for importing into project design models. The test model has been circulated to experts in the area, and their observations, as well as results of any further tests will be made publicly available.

Abstract. Owing to the increasing existence of multistorey buildings and infrastructures in the built environment, there is a need for three-dimensional (3D) land administration systems (LAS). Regarding this, condominium rights in real-estate properties are needed to be represented as 3D for preventing misinterpretations with regards to who is responsible for or has ownership in which parts of the buildings. Digitalizing the public services appears in current strategies of governments and administrations since it contributes to transparency, speed, and accurateness in the processes. Building permitting that contains obtaining the occupancy permit is a vital one of these public services. With the even-increasing adaptation of Building Information Modelling (BIM), a whole raft of Building Information Models (BIMs) are created to use in digital building permitting. Thus, a significant opportunity for 3D delineation of condominium rights comes out of the reuse of these BIMs, especially their Industry Foundation Classes (IFC) data. In this sense, this paper puts forward an approach that includes developing the conceptual model to depict condominium rights and linking that model with the IFC schema. The applicability of the approach is demonstrated by using a floor of a simple building. The study shows that IFC-based representation of condominium rights can be beneficial for the transition to 3D LAS in Turkey.

Building Information Modelling (BIM) is an emerging technology that provides a platform for a comprehensive digital representation of a facility to be created by integrating data from design conception until demolition. In seeking the optimum use of BIM, a large degree of cooperation and collaboration among multi-disciplinary contributors are required for the digital data exchange and sharing process to be deployed. This situation, however, brings up new issues in delineating liabilities and limitations of contributors as the demarcation line of each contributor becomes unclear. In Malaysia, there is no known BIM-enabled standard form of contract that preserves the intellectual property rights (IPR) of the BIM projects’ contributors. Therefore, the present study attempts to investigate the issues pertaining to IPR in the context of BIM adoption in the construction project. Qualitative methodology involving literature review, analysis of existing IPR provisions and semi-structured interviews with the experts were conducted. The research identified two major issues related to IPR in BIM projects: copyright ownership of the BIM model and data infringement. This paper is substantial to deliver knowledge to the construction industry practitioners regarding the legal and contractual considerations in the adoption of BIM.

The IFC (Industry Foundation Classes) open format has been developed by BuildingSMART and regularized through ISO standards. It has been implemented into a BIM (Building Information Modeling) informative system for the AEC industry (Architecture Engineering and Construction). The IFC format has changed interoperability processes concerning architectural and technical entities in a semantic way. However, because this standard open format was specifically designed for the modern AEC industry, it may not cater to the demands of cultural heritage assets. Since IFC classification is fundamental for informative systems, it should become a standard also concerning heritage assets, even if nowadays there is no regularized IFC classification for historical existing buildings. Specific cultural heritage peculiarities therefore need semantic classification based on historical asset families. For this reason, this work is based on a proposal and experimental IFC classification implemented inside an HBIM open source software (FreeCAD), whereby limitations of IFC standards can be overcome thanks to the freedom of access to libraries and codes. Moreover, this work is based on IFC objects management outside the platform for interoperability purposes.

Open Building Information Modelling (OpenBIM) is a collaborative project management process. Its application to road infrastructures is currently limited. OpenBIM standards for infrastructure are still under development. One of these standards is the Industry Foundation Classes (IFC), which is a data architecture for modelling infrastructure projects. The current and upcoming releases of IFCRoad focus on structuring data for the design and construction phases of an infrastructure’s lifecycle. Semantics of the O&M process phase are not fully integrated within these standards. This paper proposes an extension of the IFC schema to enrich this standard with semantics inherent in the O&M phase of road infrastructures. This extension, based on IFCInfra4OM ontology, allows the OpenBIM process to be fully applied to road infrastructures. Its implementation on a case study relative to the A7 Agadir–Marrakech Highway in Morocco enables, on the one hand, analysis and compliance with O&M management requirements on the basis of a single container: the IFC-BIM-based model. On the other hand, it allows comparison of the OpenBIM process with that of ClosedBIM for the integration of O&M data into BIM for a road infrastructure.
