TL;DR: Current trends, benefits, possible risks, and future challenges of BIM for the AEC industry are discussed and the findings of this study provide useful information for A EC industry practitioners considering implementing BIM technology in their projects.
Abstract: Building information modeling (BIM) is one of the most promising recent developments in the architecture, engineering, and construction (AEC) industry. With BIM technology, an accurate virtual model of a building is digitally constructed. This model, known as a building information model, can be used for planning, design, construction, and operation of the facility. It helps architects, engineers, and constructors visualize what is to be built in a simulated environment to identify any potential design, construction, or operational issues. BIM represents a new paradigm within AEC, one that encourages integration of the roles of all stakeholders on a project. In this paper, current trends, benefits, possible risks, and future challenges of BIM for the AEC industry are discussed. The findings of this study provide useful information for AEC industry practitioners considering implementing BIM technology in their projects.

TL;DR: The challenges incorporating new knowledge areas into constrained curricula and the various approaches that the university programs are undertaking are illustrated, which reinforce the notion that there are disparities in these educational programs, which need realignment to develop the workforce of the future that will lead the AEC industry transformations.
Abstract: The U.S. AEC industry is faced with the ever-increasing challenge of managing the public and private facilities and infrastructure to support the accomplishment of its economy. The increasing global emphasis on sustainable approaches and the need to increase efficiency and improve cost over the lifecycle of projects, demand new approaches to architecture, engineering, and construction (AEC) education. This study was initiated to look for insight into the current educational environment and to provide a baseline for possible solutions to cope with the complexity of the challenge. This paper examined 101 U.S. AEC programs focusing on emerging subject areas of Building Information Modeling (BIM) and sustainability, and reviewed how educational innovations of distance learning, multidisciplinary collaboration, industry collaborations, are incorporated to develop core competencies in those two subject areas. The researchers reviewed and categorized the AEC disciplines based on the respective accrediting bodies of ABET, NAAB, and ACCE, and surveyed the internal factors (e.g., program resources, expertise, etc.) and external factors (e.g., accreditation requirements, sustainability initiatives, etc.) that affect the pedagogical approaches. This study illustrates the challenges incorporating new knowledge areas into constrained curricula and the various approaches that the university programs are undertaking. A comparative analysis also reveals the similarities and differences and specific advantages and disadvantages of particular approaches across the AEC programs. The findings reinforce the notion that there are disparities in these educational programs, which need realignment to develop the workforce of the future that will lead the AEC industry transformations.

TL;DR: The integration of BIM, geospatial, physical modeling and 3D visualization provides a framework of interoperability that enables an intelligent synthetic model of entire urban environments.
Abstract: Using digital design models has been a common practice in the manufacturing industry for decades. Project teams at companies such as Boeing and Toyota have placed digital models at the core of their collaborative, concurrent engineering processes. The same approach, called building information modeling (BIM), is increasingly being adopted by architecture, engineering, and construction (AEC) service providers for building and infrastructure projects. Unlike CAD, which uses software tools to generate digital 2D and/or 3D drawings, BIM facilitates a new way of working: creating designs with intelligent objects that enables cross-functional project teams in the building and infrastructure industries to collaborate in a way that gives all stakeholders a clearer vision of the project. Models created using software for BIM are intelligent because of the relationships and information that are automatically built into the model. Components within the model know how to act and interact with one another. BIM not only enables engineers architects and construction firms to work more efficiently, but creates a foundation for sustainable design, enabling designers to optimize the environmental footprint of a structure during the design phase. Convergence is breaking down the barriers between technical disciplines. The integration of BIM, geospatial, physical modeling and 3D visualization provides a framework of interoperability that enables an intelligent synthetic model of entire urban environments.

TL;DR: This paper studied the organizational practices around Building Information Modelling (BIM) in inter-organizational collaborations among architects, engineers and construction professionals in order to theorize how communication supports technology adoption and argue that the dynamic complexity of design and construction processes requires what they call "messy talk" -conversations neither about topics on meeting agendas nor on specified problems or specific queries for expertise.
Abstract: We studied the organizational practices around Building Information Modelling, or BIM, in inter-organizational collaborations among architects, engineers and construction professionals in order to theorize how communication supports technology adoption. Using ethnographic observation and one-on-one interviews with project participants, we observed five teams on three different commercial and institutional building projects that each collaborated over periods of 8–10 months. In this paper, we argue that the dynamic complexity of design and construction processes requires what we call ‘messy talk’—conversations neither about topics on meeting agendas, nor on specified problems or specific queries for expertise. In messy talk interactions, AEC professionals contributed to innovation and project cohesion by raising and addressing issues not known by others. The communicative ‘affordances and constraints’ of BIM structured meeting conversations away from less structured, open-ending problem-solving and towards...
TL;DR: In this paper, the current status of BIM implementations, organizational structures, training requirements, and strategies of construction companies and examines their expectations from university construction graduates in regard to BIM knowledge and skills.
Abstract: Building Information Modeling (BIM) applications are being rapidly embraced by the construction industry to reduce cost, time, and enhance quality as well as environmental sustainability. As a result many construction firms are gaining experience with these new tools and processes and changing their expectations from university graduates. As many construction programs strive to deliver curriculum and research that is relevant to the industry, it is essential to accurately understand the impact of BIM on the operations and practice of construction companies. Accordingly, this study benchmarks the current status of BIM implementations, organizational structures, training requirements, and strategies of construction companies and examines their expectations from university construction graduates in regard to BIM knowledge and skills. An online survey was devised to understand the current level of BIM expertise and strategies of construction companies and their expectations. The survey invited national and re...

TL;DR: In this article, the authors focus on the two most fundamental shortcomings in the construction industry: the failure to deliver projects predictably: to the required quality, on time and within budget; and the failure of most firms in the industry to make a survivable level of profit.
Abstract: Constructionprojects involve a complex set of relationships, betweenpartieswith different professional backgrounds trying toachieve a very complex goal.Under these difficult circumstances,the quality of information on which projects are based should be of the highest possible standard. Theline-based, two dimensional drawings on which conventional construction is based render this all but impossible. This is thesource of somemajor shortcomings in the construction industry, and this book focuses on the two most fundamental of these: the failure to deliver projects predictably: to the required quality, on time and within budget; and the failure of most firms in the industry to make a survivable level of profit. By transforming the quality of information used in building, BIMaims totransform construction completely. After describing and explaining these problems, the way in which BIM promises to provide solutions is examined in detail. A discussion of the theory and practice of BIM is also provided, followed by a review of various recent surveys of BIM usage in the US, UK and selected European economies. The way in which other industries, including retail andmanufacturing, have been transformed by information are explored and compared with current developments in the deployment of BIM in construction. Five case studies from the UK show how BIM is being implemented, and the effects it is having on architects and contractors. This book isperfect for any construction professional interested in improving the efficiency of their business, as well as undergraduate and postgraduate students wishing to understand the importance of BIM.

TL;DR: 4D geographic information systems were used for space planning that facilitates topographic modeling, different types of geospatial analyses, and database management and a GIS-based methodology that enables space planning, time-space conflict identification, and conflict resolution prior to the construction was developed and implemented.
Abstract: Construction activities need space on the jobsite for their execution. Workers, equipment, materials, temporary facilities, and the developing structure share the limited jobsite space during the construction period. Multiple types of spaces for different purposes on various locations are required to execute various activities at different times. Hence, space planning helps provide a safe and productive environment. Planners mentally link two-dimensional (2D) drawings and execution schedules to generate dynamic multiple types of space requirements, which is a complex task. Therefore, researchers suggest the use of four-dimensional (4D) modeling and building information modeling (BIM) for space planning. Both simulate the construction process by linking the execution schedule with a three-dimensional (3D) model to visualize the construction sequence in space planning. However, both still lack features such as topography modeling and geospatial analysis, which affect space planning. In this work, 4D geographic information systems (GIS) were used for space planning that facilitates topographic modeling, different types of geospatial analyses, and database management. GIS was also used to generate multiple types of spaces corresponding to various activities. A feature attribute table (FAT) associated with each space describes when, where, and how long that space will be required on the jobsite. GIS-based area topology was implemented through a set of validation rules that define how working areas have to share the jobsite. A GIS-based methodology that enables space planning, time-space conflict identification, and conflict resolution prior to the construction was developed and implemented.

TL;DR: A framework for prospectively measuring the usability of designs before buildings are constructed, demonstrating that, to the extent that users exhibit heterogeneous behaviors and preferences, designs that allow greater local control and ease of operation perform better.
Abstract: Building information modeling is only beginning to incorporate human factors, although buildings are sites where humans and technologies interact with globally significant consequences. Some buildings fail to perform as their designers intended, in part because users do not or cannot properly operate the building, and some occupants behave differently than designers expect. Innovative buildings, e.g., green buildings, are particularly susceptible to usability problems. This paper presents a framework for prospectively measuring the usability of designs before buildings are constructed, while there is still time to improve the design. The framework, which was implemented as an agent-based computer simulation model, tests how well buildings are likely to perform, given realistic occupants. An illustrative model for lighting design shows that this modeling approach has practical efficacy, demonstrating that, to the extent that users exhibit heterogeneous behaviors and preferences, designs that allow greater local control and ease of operation perform better.

TL;DR: In this paper, the authors discuss the experience of combining BIM and LCA methods in undergraduate and graduate engineering teaching at Drexel University and the application of commercial building information modeling (BIM) software for teaching sustainable design of buildings.
Abstract: Buildings embody and consume among the largest fraction of energy within the built environment, and likewise they are responsible for large emissions of greenhouse gases (GHGs), often referred to as their carbon footprint. From smalland medium-sized buildings to the most energy intensive of structures, architects and engineers are faced with many new challenges in designing and retrofitting buildings for reduced energy and GHG intensity. Engineers and environmental scientists have been examining the embodied energy and related carbon emissions of buildings for more than 40 years (Baird and Chan 1983; Buchanan and Honey 1994; Cole 1998; Venkatarama Reddy and Jagadish 2003; Nassen et al. 2007; Kellenberger and Althaus 2009), yet arguably few undergraduates recognize this research as a basis for sustainable design. As sustainable and “green” design has become more prevalent in the architecture and engineering industries, college graduates must be prepared not only to follow environmental guidelines but also to understand the implications as well. After more than two decades of research into “greening” the design and construction of buildings, many new methods and tools have emerged to meet the energy challenges of the built environment. Residential and commercial buildings in the United States currently consume about 40% of the country’s primary energy and emit 20% of the national carbon dioxide budget (Yeang 1999; Yudelson 2007; Dimoudi and Tompa 2008; U.S. Department of Energy 2009; U.S. Energy Information Administration 2010). Thus, one major focus of sustainable building design is to reduce the carbon intensity of building components as well as lower operational energy demand (Kellenberger and Althaus 2009). Courses that focus on sustainability are becoming integral within higher education as part of greenand sustainable-engineering undergraduate programs (AASHE 2010). Within the civil engineering discipline, life-cycle assessment (LCA) has become an important analytical framework for evaluating the environmental sustainability of civil engineering infrastructure. Moreover, for architectural engineering specifically, building information modeling (BIM) is evolving as a valuable tool for meeting sustainability objectives in building programs. This paper discusses the experience of combining BIM and LCA methods in undergraduate and graduate engineering teaching at Drexel University and the application of commercial BIM and LCA software for teaching sustainable design of buildings.

TL;DR: In this paper, the authors review the legal implications of BIM adoption, including ownership and control of building information models, potential revolution in standard of care as a reaction to changes in processes and practices that are driven by past technologies.
Abstract: Building information modelling (BIM) promises some potentially radical benefits if adopted and correctly deployed on construction projects. However, significant literature evidence suggests that certain benefits of innovations such as BIM only become feasible and realizable when their legal frameworks are clear and implementable. Interestingly, existing legal frameworks for professional service delivery in architectural, engineering, construction and operations (AECO) industries are apparently biased to fragmented conventions than contemporary contractual risks in e-business. This, potentially, is a major concern against speedy adoption of BIM. Arguably, AECO industries have not remained static in the past years regarding the adoption of integrated technologies that enable creation and sharing of information across discipline boundaries. Moreover, integrated systems have a long history in construction which is not limited to BIM - there are other software applications that are being deployed to service integrated innovations and multidisciplinary business systems. Whilst the industry still struggles to improve on the speed of adopting and deploying these innovative technologies, the herculean task is how to create workable legal frameworks that will service the potential benefits being proposed in BIM. Some variables of contractual risks in changing technologies have been conceptualized in some recent studies; with recommendations on some useful modifications to conventional legal frameworks in e-contracting, which are not yet very definitive at present. This article reviews scholarly perspectives regarding legal implication of BIM adoption: ownership and control of BIM models, potential revolution in standard of care as a reaction to changes in processes and practices that are driven by past technologies. Professional liabilities in electronic and integrated project delivery systems are also discussed. In the end, conclusions are drawn on potential benefits of resolving these challenges.

TL;DR: Feedback as obtained from questionnaire surveys of students who learned BIM at BRE is analyzed and presented which highlights the knowledge they gained by learning and practicing BIM.
Abstract: SUMMARY: Building Information Modelling (BIM) is a thriving technology and approach for the Architecture, Engineering and Construction (AEC) Industry which facilitates, among others, the functions of planning, design, construction and operation of the project lifecycle. BIM is gradually replacing the 2D or 3D CAD technology in many parts of the world. BIM offers wider range of applications than CAD. Therefore, its learning needs are different from the learning needs of CAD. Educators around the world are contemplating with various approaches and methodologies for teaching BIM to tertiary students of the AEC disciplines enabling them to apply BIM in their future careers. These approaches are reviewed in this paper along with the initiatives being taken by the Department of Building and Real Estate (BRE) of the Hong Kong Polytechnic University (PolyU) to incorporate BIM in the construction management, building technology and quantity surveying curricula. Feedback as obtained from questionnaire surveys of students who learned BIM at BRE is analyzed and presented which highlights the knowledge they gained by learning and practicing BIM. Such an approach can be used at universities in other regions and countries and can serve as a guideline for BIM implementations.

TL;DR: The concept of Building interactive Modeling (BiM) is presented which complements the capabilities of BIM with social interaction to enhance collaborative information and knowledge sharing and role-playing scenarios developed in Second Life demonstrate specific opportunities of BiM.
Abstract: The number of design and construction professionals who are using Building Information Modeling (BIM) is rapidly growing and simultaneously the architecture, engineering, and construction (AEC) community is faced with the challenge of remote collaboration as offshore outsourcing continues to grow. While BIM facilitates information sharing between AEC professionals via purpose-built three-dimensional (3D), 4D design, analysis, evaluation, and documentation models, the communication of such 3D data-rich models if often fragmented and typically limits real-time communication and interaction of users who may be geographically dispersed and/or lack the modeling and analyses skills to interact with these models. AEC education needs to expose students to these emerging practice changes while finding new ways to more effectively address the fundamentals of design and construction. Virtual worlds – in this research the Second Life platform – have the potential to address the communication issues and effectively complement traditional teaching approaches and furthermore integrate with BIM to enhance construction education. Nevertheless, despite the potential benefits of virtual worlds, various obstacles exist. This paper presents the concept of Building interactive Modeling (BiM) which complements the capabilities of BIM with social interaction to enhance collaborative information and knowledge sharing. Role-playing scenarios developed in Second Life demonstrate specific opportunities of BiM.
TL;DR: In this paper, the authors propose a multidisciplinary framework to integrate applications of laser scanning technology with the fundamentals of 3D model-based design, and analyze the construction engineering requirements of laser-scanning technology for applications across all phases of the project life cycle.
Abstract: Laser scanning for rapid spatial data acquisition is an established technology in the architecture, engineering, and construction (AEC) sector with a wide range of applications. An understanding of the wide variation of technical requirements and considerations associated with these applications is critical to decision making about laser-scanning implementation on projects. Furthermore, significant industry transformations in the use of building information modeling present extraordinary opportunities for AEC professionals to employ the use of laser scanning in the context of holistic, collaborative workflows grounded in three-dimensional model-based design. This report analyzes the construction engineering requirements of laser scanning technology for applications across all phases of the project life cycle and proposes a multidisciplinary framework to integrate applications of laser scanning technology with the fundamentals of three-dimensional model-based design.
