Adoption processes for EDM, EDI and BIM technologies in the construction industry

Three strategically important uses of IT in the construction industry are the storage and management of project documents on webservers (EDM), the electronic handling of orders and invoices between companies (EDI) and the use of 3-D models including non-geometrical attributes for integrated design and construction (BIM). In a broad longitudinal survey study of IT use in the Swedish Construction Industry the extent of use of these techniques was measured in 1998, 2000 and 2007. The results showed that EDM and EDI are currently already well-established techniques whereas BIM, although it promises the biggest potential benefits to the industry, only seems to be at the beginning of adoption. In a follow-up to the quantitative studies, the factors affecting the decisions to implement EDM, EDI and BIM as well as the actual adoption processes, were studied using semi-structured interviews with practitioners. The theoretical basis for the interview studies was informed by theoretical frameworks from IT-adoption theory, where in particular the UTAUT model has provided the main basis for the analyses presented here. The results showed that the decisions to take the above technologies into use are made on three differ- ent levels: the individual level, the organizational level in the form of a company, and the organiza- tional level in the form of a project. The different patterns in adoption can to some part be explained by where the decisions are mainly taken. EDM is driven from the organisation/project level, EDI mainly from the organisation/company level, and BIM is driven by individuals pioneering the technique.

Building Information Modelling (BIM) Software Interoperability: A Review of the Construction Sector

Building Information Modelling (BIM) is continuing to evolve and develop as the construction industry progresses towards level 2 maturity. However, one of the core barriers in this progression is the aspect of interoperability between software packages. This research and paper stems from a Knowledge Transfer Partnership (KTP) where both industry and academia come together to address this shortcoming within the sector. One of the core objectives of this partnership and the aim of this study is investigating potential solutions to this barrier, while also developing best working practices to be applied in industry. Using one of the case studies from this partnership (a temporary steel structure), this paper demonstrates a potential solution to addressing interoperability within structural analysis and detailing packages, MasterSeries and Revit respectively. The findings of the research indicate that a process based approach rather than that of additional software coding as being the preferred solution. The results of this preliminary research will aid in the development of the topic of interoperability within the sector, while also developing the knowledge and competencies of the parties within the KTP. The findings are explored further, by providing an overview of the resolution process adopted in this case study, in overcoming the interoperability that arose as the project progressed. It is envisaged that this study will assist the construction sector and its adoption of BIM technologies, while also addressing the critical aspect of operability between software.

Análise da interoperabilidade aplicada ao projeto BIM de Estruturas Metálicas

O BIM – Building Information Modeling – é um conceito de controlo e gestão de informação desenvolvida, entre diferentes especialidades e intervenientes envolventes, durante o ciclo de vida das construções. A utilização das tecnologias BIM, no ramo da Engenharia Mecânica e Civil, tem sido uma aposta constante, e cada vez mais concisa, nos projetos de construção. A justificação para a adoção destas metodologias mais eficientes, em substituição dos processos convencionais, prende-se com o facto desses processos convencionais, ainda hoje, apresentarem muitas dificuldades e problemas associados, por exemplo, à falta de comunicação entre os intervenientes e ao ineficiente controlo na gestão de projetos. O objetivo desta dissertação centra-se na análise da interoperabilidade de softwares BIM, ou seja, na verificação da viabilidade de exportação de dados dos modelos produzidos, entre as ferramentas BIM. Para este campo de ação contribuirá a análise da passagem de informação, relativa ao modelo de uma Nave Industrial modelada, em alguns dos softwares BIM, correntemente mais utilizados. O conhecimento adquirido com a modelação do caso de estudo do presente trabalho irá permitir identificar algumas lacunas existentes ao nível da falta de recomendações práticas que sirvam de orientação na modelação recorrendo a ferramentas informáticas BIM-compatíveis. Assim, a base deste trabalho consiste na criação de uma série de recomendações ou de um roteiro de modelação em específico para a disciplina de estruturas enquanto área de aplicação concreta do estudo efetuado. Nesse sentido, a proposta deste trabalho é de apresentar alguns critérios de modelação onde são definidos os elementos a modelar em cada fase do projeto.

BIM: innovation in design management, influence and challenges of implementation

The construction industry is widely being criticised as a fragmented industry. There are mounting calls for the industry to change. The espoused change calls for collaboration as well as embracing innovation in the process of design, construction and across the supply chain. Innovation and the application of emerging technologies are seen as enablers for integrating the processes ‘integrating the team’ such as building information modelling (BIM). A questionnaire survey was conducted to ascertain change in construction with regard to design management, innovation and the application of BIM as cutting edge pathways for collaboration. The respondents to the survey were from an array of designations across the construction industry such as construction managers, designers, engineers, design coordinators, design managers, architects, architectural technologists and surveyors. There was a general agreement by most respondents that the design team was responsible for design management in their organisation. There is a perception that the design manager and the client are the catalyst for advancing innovation. The current state of industry in terms of incorporating BIM technologies is posing a challenge as well as providing an opportunity for accomplishment. BIM technologies provide a new paradigm shift in the way buildings are designed, constructed and maintained. This paradigm shift calls for rethinking the curriculum for educating building professionals, collectively.

La strategia BIM a supporto del progetto della sicurezza nel cantiere edile: il caso dell'ospedale di primo soccorso a Lampedusa.

Throughout this research, the whole life cycle of a building will be analyzed, with a special focus on the most common issues that affect the construction sector nowadays, such as safety. In fact, the goal is to enhance the management of the entire construction process in order to reduce the risk of accidents. The contemporary trend is that of researching new tools capable of reducing, or even eliminating, the most common mistakes that usually lead to safety risks. That is one of the main reasons why new technologies and tools have been introduced in the field. The one we will focus on is the so-called BIM: Building Information Modeling. With the term BIM we refer to wider and more complex analysis tool than a simple 3D modeling software. Through BIM technologies we are able to generate a multi-dimension 3D model which contains all the information about the project. This innovative approach aims at a better understanding and control of the project by taking into consideration the entire life cycle and resulting in a faster and more sustainable way of management. Furthermore, BIM software allows for the sharing of all the information among the different aspects of the project and among the different participants involved thus improving the cooperation and communication. In addition, BIM software utilizes smart tools that simulate and visualize the process in advance, thus preventing issues that might not have been taking into consideration during the design process. This leads to higher chances of avoiding risks, delays and cost increases. Using a hospital case study, we will apply this approach for the completion of a safety plan, with a special focus onto the construction phase.

Critical factors for waste management in office building retrofit projects in Australia

Office building retrofit is a sector being highlighted in Australia because of the mature office building market characterised by a large proportion of ageing properties. The increasing number of office building retrofit projects strengthens the need for waste management. Retrofit projects possess unique characteristics in comparison to traditional demolition and new builds such as partial operation of buildings, constrained site spaces and limited access to as-build information. Waste management activities in retrofit projects can be influenced by issues that are different from traditional construction and demolition projects. However, previous research on building retrofit projects has not provided an understanding of the critical issues affecting waste management. This research identifies the critical factors which influence the management of waste in office building retrofit projects through a literature study and a questionnaire survey to industry practitioners. Statistical analysis on a range of potential waste issues reveals the critical factors, as agreed upon by survey respondents in consideration of their different professional responsibilities and work natures. The factors are grouped into five dimensions, comprising industry culture, organisational support and incentive, existing building information, design, and project delivery process. The discussions of the dimensions indicate that the waste management factors of office building retrofit projects are further intensified compared to those for general demolition and construction because retrofit projects involve existing buildings which are partially operating with constrained work space and limited building information. Recommendations for improving waste management in office building retrofit projects are generalised such as waste planning, auditing and assessment in the planning and designing stage, collaboration and coordination of various stakeholders and different specialists, optimised building surveying and BIM technologies for waste analysis, and new design strategies for waste prevention.

Social sensing in the field: Challenges in detecting social interactions in construction sites

Construction industry is a sector that is renowned for the slow uptake of new technologies. This is usually due to the conservative nature of this sector that relies heavily on tried and tested and successful old business practices. However, there is an eagerness in this industry to adopt Building Information Modelling (BIM) technologies to capture and record accurate information about a building project. But vast amounts of information and knowledge about the construction process is typically hidden within informal social interactions that take place in the work environment. In this paper we present a vision where smartphones and tablet devices carried by construction workers are used to capture the interaction and communication between workers in the field. Informal chats about decisions taken in the field, impromptu formation of teams, identification of key persons for certain tasks, and tracking the flow of information across the project community, are some pieces of information that could be captured by employing social sensing in the field. This information can not only be used during the construction to improve the site processes but it can also be exploited by the end user during maintenance of the building. We highlight the challenges that need to be overcome for this mobile and social sensing system to become a reality. © 2012 ACM.

The application of building information modelling in a construction project in China

Previous studies have proved the application of Building InformationModelling (BIM) can lead to greater efficiencies. Slowly adopting newtechnologies and limited technological innovation are criticised for theconstruction industry. In this paper, we present research that examinesthe practices of BIM technologies for the clash detection and coordination among building structure, equipment and pipelines, quantity statistics and construction simulation in a construction project in China. The BIM application significantly promotes the abilities to achieve construction schedule, quality, budget, and scope objectives in the project. The technological capabilities of BIM, the illegal issues of BIM outputs and developing cooperative project management culture are needed in order to promote BIM application in the construction industry.

BIM – implications for government

As ‘The Architect’s Handbook of Professional Practice’ (cited by Riskus (2007) suggests, Building Information Modelling, or BIM, is “the use of virtual building information models to develop building design solutions, design documentation, and to analyse construction processes”. We would suggest such a definition, while useful, should be extended to include the operational phases of built assets (such as maintenance and decommissioning), and also be applied to the whole area of infrastructure. As a set of technologies, BIM holds promise to deliver benefits for the property, construction, and infrastructure management industries – particularly improved efficiencies and effectiveness through enhanced collaboration at all stages of the construction cycle. There are several important qualifiers, barriers, enablers, and some disadvantages with this suite of technologies. This report outlines the costs and benefits enablers and barriers associated with BIM, and makes suggestions about how these issues may be addressed.

BIM : enabling sustainability and asset management through knowledge management

Building Information Modeling (BIM) is the use of virtual building information models to develop building design solutions and design documentation and to analyse construction processes. Recent advances in IT have enabled advanced knowledge management, which in turn facilitates sustainability and improves asset management in the civil construction industry. There are several important qualifiers and some disadvantages of the current suite of technologies. This paper outlines the benefits, enablers, and barriers associated with BIM and makes suggestions about how these issues may be addressed. The paper highlights the advantages of BIM, particularly the increased utility and speed, enhanced fault finding in all construction phases, and enhanced collaborations and visualisation of data. The paper additionally identifies a range of issues concerning the implementation of BIM as follows: IP, liability, risks, and contracts and the authenticity of users. Implementing BIM requires investment in new technology, skills training, and development of new ways of collaboration and Trade Practices concerns. However, when these challenges are overcome, BIM as a new information technology promises a new level of collaborative engineering knowledge management, designed to facilitate sustainability and asset management issues in design, construction, asset management practices, and eventually decommissioning for the civil engineering industry.

An approach for extending Building Information Models (BIM) to specifications

The Construction industry accounts for a tenth of global GDP. Still, challenges such as slow adoption of new work processes, islands of information, and legal disputes, remain frequent, industry-wide occurrences despite various attempts to address them. In response, IT-based approaches have been adopted to explore collaborative ways of executing construction projects. Building Information Modelling (BIM) is an exemplar of integrative technologies whose 3D-visualisation capabilities have fostered collaboration especially between clients and design teams. Yet, the ways in which specification documents are created and used in capturing clients' expectations based on industry standards have remained largely unchanged since the 18th century. As a result, specification-related errors are still common place in an industry where vast amounts of information are consumed as well as produced in the course project implementation in the built environment. By implication, processes such as cost planning which depend on specification-related information remain largely inaccurate even with the use of BIM-based technologies. This paper briefly distinguishes between non-BIM-based and BIM-based specifications and reports on-going efforts geared towards the latter. We review exemplars aimed at extending Building Information Models to specification information embedded within the objects in a product library and explore a viable way of reasoning about a semi-automated process of specification using our product library.

BIM - Implications for government (Case Study No. 5 [2004-032-A + Case study no. 5])

BIM as a suite of technologies has been enabled by the significant improvements in IT infrastructure, the capabilities of computer hardware and software, the increasing adoption of BIM, and the development of Industry Foundation Classes (IFC) which facilitate the sharing of information between firms. The report highlights the advantages of BIM, particularly the increased utility and speed, better data quality and enhanced fault finding in all construction phases. Additionally BIM promotes enhanced collaborations and visualisation of data mainly in the design and construction phase. There are a number of barriers to the effective implementation of BIM. These include, somewhat paradoxically, a single detailed model (which precludes scenarios and development of detailed alternative designs); the need for three different interoperability standards for effective implementation; added work for the designer which needs to be recognised and remunerated; the size and complexity of BIM, which requires significant investment in human capital to enable the realisation of its full potential. There are also a number of challenges to implementing BIM. The report has identified these as a range of issues concerning: IP, liability, risks and contracts, and the authenticity of users. Additionally, implementing BIM requires investment in new technology, skills training and development of news ways of collaboration. Finally, there are likely to be Trade Practices concerns as requiring certain technology owned by relatively few firms may limit

Technical features of BIM servers for collaboration on building and construction projects

This paper reviews the technical features and requirements of Building Information Modelling (BIM)-servers as collaboration platforms for multi-disciplinary building and construction projects. Multi-disciplinary collaboration is the norm in the Architecture, Engineering, and Construction (AEC) industries, especially in complex projects. The widespread adoption of object-oriented Computer-aided Design (CAD) tools that support BIM capabilities has generated greater interest in model based exchange of information across disciplines and consultants who have traditionally collaborated through the frequent exchange of 2D drawings and documents. BIM-servers are collaboration platforms that are expected to provide the technical capability to support this inter-disciplinary exchange of 3D models in addition to intelligent management of the related drawings, documents and other forms of data. Since BIM-servers are a recent technical development a review of their technical features can help further development. This paper serves this objective by providing a review of the technical features and requirements for using BIM-servers as multi-disciplinary collaboration platforms on building and construction projects. The methodologies include focus group interviews (FIGs) with representatives from the diverse AEC disciplines, a case study on a state-of-the-art BIM-server, and a critical review and analysis of current collaboration platforms that are available to the AEC industries. This paper concludes that greater emphasis should be placed on supporting technical requirements to facilitate technology management and implementation across disciplines. Their implications for user-centric technology development in design and construction industry are also discussed.
