Building Information

Building Information Modeling (BIM) related promises are numerous – reduction of the architecture, engineering and construction (AEC) industry fragmentation, construction cost, and delivery time, as well as lifecycle optimization have been advocated in both literature and practice. But so are the challenges of BIM adoption: establishment and standardization of BIM data structures or ensuring the necessary skills and competencies for planning process participants. In this paper we present ongoing research on the integration of BIM in education through student experiments, based on a BIM-supported integrated design studio (IDS). Thereby the various features of BIM technology adopted in multidisciplinary conceptual design stage are explored and evaluated. Quantitative and qualitative research, in form of questionnaires and focus group discussions, addresses the people and process related challenges in such collaborative BIMsupported building projects. The analysis of three cycles of such IDSs has shown that the participants appreciate the collaborative approach, and benefit from working with other disciplines by sharing knowledge; however BIM technology has not significantly contributed to the improvement of the design quality.

Building Information

Buildings contribute more than 40% of world energy consumption, so it is feared that it will cause energy problems in thefuture, especially in the construction sector. One solution to reducing this problem is by analyzing energy use at the initialdesign stage and utilizing solar energy as one of the solar power plants (PLTS) in office buildings. To analyze the use ofenergy in buildings, Building Information Modeling (BIM) was used. The purpose of this research is to analyze the annualenergy level of office buildings in Palembang using BIM software, namely Autodesk Revit. The number of solar panels aswell as the amount of energy were also identified using web-based software (HelioScope) resulting the economic feasibilityas indicated by the installation of solar panels as a component of PV mini-grid. The results showed that the use of BIMtechnology in analyzing building energy can provide a detailed description of the building model at the design stage. Revitanalysis indicates that the building consumed electrical energy per year for about 3,647,713 kWh with a roof area of 1,657m2. In addition, based on the HelioScope analysis, the use of renewable energy from the installation of PLTS was 152,900kWh/year. Meanwhile, for economic feasibility analysis, the installation of PLTS in office buildings can provide a positive NetPresent Value (NPV), indicating a feasible project.

Die Anforderungen an den Planungsprozess, insbesondere hinsichtlich der Planungsqualität, nehmen bei steigendem Kostendruck immer mehr zu. Gleichzeitig verlaufen der Planungs- sowie der begleitende Kommunikationsprozess zwischen den unterschiedlichen beteiligten Gewerken zunehmend digital. Der Planungsansatz des Building Information Modeling (BIM) verfolgt eben diese Ziele, im Wesentlichen aber bei der Planung und dem Betrieb von Gebäuden. Im Beitrag wird untersucht, wie sich der BIM-Ansatz auf die Fabrikplanung übertragen lässt.   The requirements of the planning process, in particular with regard to the planning quality, rise more and more with increasing cost pressure. At the same time, the planning process and the accompanying communication process between the different work areas involved are increasingly digital. The planning approach of Building Information Modeling (BIM) pursues precisely these goals, but essentially in the planning and operation of buildings. The article examines how the BIM approach can be transferred to factory planning.

Building Information

At the present stage of the development of the construction industry, based on the principles of sustainable development, special attention should be paid to the formation of construction waste. Reserves for improving the level of efficiency of waste management can be found in the application of modern information technologies and their adaptation to resource-saving problems. The use of information systems is advisable at all stages of the life cycle of a building. Today, the technology of building information modeling (BIM) is actively developing, which can significantly reduce the amount of waste generation in construction. This is possible with its implementation at the design stage, in order to avoid irrational design decisions, collisions, etc. Information systems for data transmission allow rapid exchange of information between project participants, promptly warn about changes in space-planning decisions, materials, structures and equipment. At the stage of operation, in the presence of the information model of the building, it is possible to create a planning system for the organization of works of major overhaul or reconstruction. This article also proposes a description of the functions that an information system must have aimed at coordinating the management of construction waste in the region.

The Impact

Drastic changes are occurring in the construction industry. Building Information Modeling (BIM) processes and technologies, and new Integrated Project Delivery (IPD) approaches are transforming the way buildings are planned, designed, built and operated. With the needs for new skills to cope with these accelerating changes, architecture, engineering and construction (AEC) associations in the United States are working with universities to reengineer teaching programs, integrating architecture training within an engineering and construction curriculum. Leading universities are already developing new programs, such as BIM studio courses, and promoting new ways to teach practice knowledge within design laboratories.These changes are also starting to occur in the Canadian industry. Some large governmental bodies are starting to request that their projects are designed and built using BIM. Canadian universities must respond to these changing requirements to prepare future architects, engineers, and construction managers for these new challenges and emerging industry needs. This paper provides examples for how to bridge this gap by bringing practice knowledge and research to the classroom. First, it synthesizes the impact of BIM and IPD on engineering practices in Canada. Second, it describes curriculum development undertaken between a school of architecture and two engineering departments for the development of multidisciplinary design studios to teach integrated design and BIM. Case studies are set in urban contexts and include the development of new buildings as well as refurbishment proposals for an industrial obsolete landmark. Finally, learning from this teaching and research experience, it raises questions and issues regarding our readiness to cope with this paradigm shift.

Building information modeling (BIM) implementation has been mandated in building projects in Singapore, but a wider adoption is still desired. This study aims to investigate the factors influencing BIM diffusion and examine how the factors influence firms with different project roles, firm sizes, and BIM implementation experience. The results of a pilot study, a questionnaire survey with 89 professionals, and five post-survey interviews showed that hindrances related to inadequate multi-party collaboration (whether formal or informal), conservative mindset, limited skills, costly infrastructure and training, and multi-discipline model integration were the most influential, whereas drivers associated with project leadership team’s strategic consensus, multi-disciplinary design coordination, training, and government regulations were top-ranked. Subgroup analyses between pairs of firms with different characteristics revealed that while construction firms and less experienced stakeholders tended to underestimate BIM implementation difficulties, small-medium contractors might underestimate relevant benefits. The findings and managerial recommendations help different types of firms prioritize resources to overcome hindrances, seize opportunities (such as gaining a competitive edge from BIM practical experience), and obtain support from workers executing BIM daily. With major stakeholders’ recognition and implementation, BIM can be successfully diffused in building projects and firms. The Singapore government and other countries can refer to this study when further issuing BIM diffusion policies.

PurposeThe purpose of this paper is to investigate the current practices of the early facilities management (FM) involvement during the design development and review stages (DDRS), and recommend activities aimed at achieving better integration.Design/methodology/approachA comprehensive literature review was conducted to ascertain the challenges faced by the integrated design team (IDT) in the absence of the facilities managers’ review of design solutions, and underscore the significance of the early involvement of facilities managers during the DDRS. A questionnaire survey was then developed for collecting data on eight aspects of the current practices of early FM involvement during the DDRS. The questionnaire survey was administered to the FM departments of 13 long established, public universities in Saudi Arabia. Ten responses were obtained and analyzed.FindingsThe findings suggest that the early involvement of the FM department enhances the operation and maintenance of facilities. This has been measured through reductions in the number of architectural, structural, electrical, plumbing, heating, ventilating and air conditioning defects.Practical implicationsRecommendations were provided to facilitate the process of integrating the practices of two influential stakeholders of building projects. These recommendations encompass the need for maintainability considerations at the early schematic stage, the necessity of direct contact between the two parties and the necessity of facility managers’ increased familiarity of the design stage activities, among other recommendations. In this way, the study promotes the awareness of the significance of integrating FM with the IDT at the DDRS.Originality/valueThis study contributes to the literature and practice by presenting a detailed analysis of the integration process between the FM department and the IDT. Furthermore, the outcomes of the integration between the parties were measured to assess the effectiveness of the collaboration and highlight the possible areas of improvement.

Pedagogical Frameworks

The implementation of BIM in higher education (HE) curricula for architecture and engineering is limited and does not meet the demand for competency in the industry. BIM education is mostly initiated by enthusiasts offering software training in isolated courses. The transfer of educational experiences is limited and partial. This conceptual paper explores the use of pedagogical frameworks to enable the systematic implementation of BIM in higher education. The following pedagogical frameworks are explored: (a) Integrated Design and Delivery Solutions (IDDS), (b) Technological Pedagogical Content Knowledge (TPACK), and (c) Trinity of BIM as building information model/ -modelling/ -management (BIM3P). BIM-related methods are connected to the pedagogical framework to illustrate applicable implementation. This enable BIM to be integrated into most architecture and engineering subjects without separate training in software. Focus is given to understanding relevant information to support design and fact-based decisions. The approach is learning BIM for learning architecture and engineering.

Balanced Clustering

The automated reconstruction of Building Information Modeling (BIM) objects from point cloud data is still subject of ongoing research. A vital step in the process is identifying the observations for each wall object. Given a set of segmented and classified point clouds, the labeled segments should be clustered according to their respective objects. The current processes to perform this task are sensitive to noise, occlusions, and the associativity between faces of neighboring objects. The proper retrieval of the observed geometry is especially important for wall geometry as it forms the basis for further BIM reconstruction. In this work, a method is presented to automatically group wall segments derived from point clouds according to the proper walls of a building. More specifically, a Conditional Random Field is employed that evaluates the context of each wall segment in order to determine which wall it belongs to. First, a set of classified planar primitives is obtained through algorithms developed in prior work. Next, both local and contextual features are extracted based on the nearest neighbors and a number of seeds that are heuristically determined. The final wall clusters are then computed by decoding the graph. The method is tested on our own data as well as the 2D-3D-Semantics (2D-3D-S) benchmark data of Stanford. Compared to a conventional region growing method, the proposed method reduces the rate of false positives, resulting in better wall clusters. Overall, the method computes a more balanced clustering of the observations. A key advantage of the proposed method is its capability to deal with wall geometry in complex configurations in multi-storey buildings opposed to the presented methods in current literature.

In the architecture, engineering, and construction (AEC) industry, creating an indoor model of existing buildings has been a challenging task since the introduction of building information modeling (BIM). Because the process of BIM is primarily manual and implies a high possibility of error, the automated creation of indoor models remains an ongoing research. In this paper, we propose a fully automated method to generate 2D floorplan computer-aided designs (CADs) from 3D point clouds. The proposed method consists of two main parts. The first is to detect planes in buildings, such as walls, floors, and ceilings, from unstructured 3D point clouds and to classify them based on the Manhattan-World (MW) assumption. The second is to generate 3D BIM in the industry foundation classes (IFC) format and a 2D floorplan CAD using the proposed line-detection algorithm. We experimented the proposed method on 3D point cloud data from a university building, residential houses, and apartments and evaluated the geometric quality of a wall reconstruction. We also offer the source code for the proposed method on GitHub.
