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>

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.

Key Steps

Building information modeling (BIM) is a process that has shown great potential in the building industry, but it has not reached the same level of maturity for transportation infrastructure. There is a standardization need for information exchange and management processes in the infrastructure that integrates BIM and Geographic Information Systems (GIS). Currently, the Industry Foundation Classes standard has harmonized different infrastructures under the Industry Foundation Classes (IFC) 4.3 release. Furthermore, the usage of remote sensing technologies such as laser scanning for infrastructure monitoring is becoming more common. This paper presents a semi-automated framework that takes as input a raw point cloud from a mobile mapping system, and outputs an IFC-compliant file that models the alignment and the centreline of each road lane in a highway road. The point cloud processing methodology is validated for two of its key steps, namely road marking processing and alignment and road line extraction, and a UML diagram is designed for the definition of the alignment entity from the point cloud data.

Building Information Modeling (BIM) technology is one of the most actively developing approaches to the digital representation of the design of buildings and structures, which makes it possible to ensure the relationship of both geometric and functional characteristics of a designed object. The organization of information exchange within the framework of the development of IM during various stages of the life cycle is a rather difficult task, since the historical development of software products used for the design of IM elements has led to the use of various data presentation formats for solving specialized design and calculation problems. In the documents analyzed in the work, two formats with an open specification — IFC and XML — are mentioned as a means of information exchange in the development of IM. In addition to the undoubted advantages of using the IFC using the EXPRESS data specification language as a means of ensuring the interoperability of information systems, there are currently difficulties with the practical application of this format in information modeling, including for organizing joint work. XML-schema can be used as an alternative to the representation of IM in the IFC for organizing data exchange between various information systems, including when implementing joint work on IM through web applications. The use of alternative to EXPRESS schemes for the definition of IM data makes it possible to simplify the organization of information transfer between participants in the information exchange, as well as to unify the presentation of design information.

Challenging Situation

Abstract Diverse industries have recognized the significance of a neutral data standard for seamless building information modeling (BIM) data exchanges and adopted commonly agreed schemes such as the industry foundation classes (IFC) schema for enhancing BIM data interoperability. To selectively employ domain-specific data exchange requirements, the AEC-FM (the Architecture, Engineering, Construction, and Facility Management) industries have developed their own schema with a subset of the IFC schema, named a model view definition (MVD). However, because of latent human errors, inadequate MVD definitions, and error-prone data mapping problems, the adoption of IFC for exchanging and sharing BIM data is frequently limited with severe data integrity issues. This challenging situation requires the detailed examination of the limitations of the heterogeneous IFC translation processes of the current BIM authoring and application tools. To accomplish this objective, the authors thoroughly investigated the two MVDs, the Coordination View Version 2.0 and the Construction Operations Building Information Exchange, broadly used as an international standard for developing the IFC translation processes, and then identified their intrinsic requirements/rules and developed rule-based data validation processes. These new intrinsic knowledge of the two MVD specifications will be fundamental foundations to create coherent BIM data exchange systems that are currently scattered and dispersed in heterogeneous IFC translation processes and structures. Newly revealed rules pertaining to these two MVDs have been executed with IfcDoc, which is the IFC documentation tool. This BIM data validation process is expected to not only accurately evaluate the translation processes between BIM native data and IFC ones but also help industry professionals ensure the integrity and the accuracy of their BIM data according to the BIM data exchange standards using the two MVDs. In addition, the outcomes of this research study are expected to bolster the interoperable BIM adoption and offer the values of greater consistency of BIM data exchange.

The analysis of road safety is critical in road design. Complying to guidelines is not enough to ensure the highest safety levels, so many of them encourage designers to virtually recreate and test their roads, benefitting from the evolution of driving simulators in recent years. However, an accurate recreation of the road and its environment represents a real bottleneck in the process. A very important limitation lies in the diversity of input data, from different sources and requiring specific adaptations for every single simulator. This paper aims at showing a framework for recreating faster virtual scenarios by using an Industry Foundation Classes (IFC)-based file. This methodology was compared to two other conventional methods for developing driving scenarios. The main outcome of this study has demonstrated that with a data exchange file in IFC format, virtual scenarios can be faster designed to carry out safety audits with driving simulators. As a result, the editing, programming, and processing times were substantially reduced using the proposed IFC exchange file format through a BIM (Building Information Modeling) model. This methodology facilitates cost-savings, execution, and optimization resources in road safety analysis.

Previous geo-referencing approaches for building information modeling (BIM) models can be problematic due to: (a) the different interpretations of the term ‘geo-referencing’, (b) the insufficient consideration of the placement hierarchy of the industry foundation classes (IFCs), and (c) the misunderstanding that a common way to embed spatial reference information for IFC is absent. Therefore, the objective of this study is to (1) clarify the meaning of geo-referencing in the context of BIM/GIS data integration, and (2) develop a common geo-referencing approach for IFC. To achieve the goal, a systematic and thorough investigation into the IFC standard was conducted to assess the geo-referencing capability of IFC. Based on the investigation, a geo-referencing approach was established using IFC entities that are common in different IFC versions, which makes the proposed approach common to IFC. Such a geo-referencing approach supports automatic geo-referencing that would facilitate the use of BIM models in GIS, e.g., for the construction of digital twins.

Since the expression "Building Information Modeling" (BIM) was initially presented in the Engineering and Construction AEC industry in the most recent decade; it has changed numerous parts of the design, construction, and operation of a building. BIM is a middleware connector that represents the advancement and utilization of PC. BIM has various frameworks which have been conducted by the pioneers in the BIM industry to enhance the BIM process. There is a study of the reflection of those frameworks on the Egyptian AEC industry to overcome the threats that prevent Egypt from applying BIM technology more broadly. In addition, a comparison is conducted between the successful countries which implemented BIM in their projects and managed to enhance their adoption by examining the local challenges and targets. The countries then made strategies and standards to overcome the aforementioned obstacles. Furthermore, successful actions were applied that can match with the Egyptian industrial requirements. This paper is expected to define the challenges which are facing the Egyptian industry to apply BIM and the potential capabilities of solving those problems. To acquire the vital information to carry on this paper, a questionnaire was created and distributed in the AEC community. The reason for the study was to see how experts consider BIM as a device in the fields of design and construction in general and in the Egyptian industry particularly. The aim of this paper is to propose a framework through several case studies which are discussed, analyzed and compared. The purpose of the analysis is to explore the importance of using BIM. Additionally, exploring the effect of different parameters on implementing BIM helped significantly during the process. It starts with proposing its framework with evaluating matrix that contains attributes to measure its success, moreover, it serves as a great help to the Egyptian companies that make real business decisions about enhancing BIM implementation through this framework.
