Requirements for model server enabled collaborating on building information models

The application of Building Information Modelling (BIM) has demonstrated enormous potential to deliver consistency in the construction collaboration process. BIM can define an explicit configuration for digitized information exchange, however the technology to collaborate on models has not yet delivered the industry requirements for BIM collaboration. This research project is intended to provide a fresh review of industry requirements for BIM collaboration and will analyse how these requirements can be supported using a model server as a collaboration platform. This paper presents a review of existing collaboration platforms, with a particular focus to evaluate the research and development efforts on model servers as a collaboration platform. This paper also reports on the findings of three focus group sessions with industry practitioners to identify any problems in the available collaboration systems. The focus group findings identify a number of issues in current collaboration environments which help to understand the main domains of user requirements for BIM collaboration. These requirement domains will be further analysed to identify functional and technical specifications for a model server enabled collaboration platform

A study of BIM collaboration requirements and available features in existing model collaboration systems

Established collaboration practices in the construction industry are document centric and are challenged by the introduction of Building Information Modelling (BIM). Document management collaboration systems (e.g. Extranets) have significantly improved the document collaboration in recent years; however their capabilities for model collaboration are limited and do not support the complex requirements of BIM collaboration. The construction industry is responding to this situation by adopting emerging model collaboration systems (MCS), such as model servers, with the ability to exploit and reuse information directly from the models to extend the current intra-disciplinary collaboration towards integrated multi-disciplinary collaboration on models. The functions of existing MCSs have evolved from the manufacturing industry and there is no concrete study on how these functions correspond to the requirements of the construction industry, especially with BIM requirements. This research has conducted focus group sessions with major industry disciplines to explore the user requirements for BIM collaboration. The research results have been used to categorise and express the features of existing MCS which are then analysed in selected MCS from a user’s perspective. The potential of MCS and the match or gap in user requirements and available model collaboration features is discussed. This study concludes that model collaborative solutions for construction industry users are available in different capacities; however a comprehensive custom built solution is yet to be realized. The research results are useful for construction industry professionals, software developers and researchers involved in exploring collaborative solutions for the construction industry

BIM collaboration: A conceptual model and its characteristics

Relationship management has become an important issue for both academics and practitioners in construction project management. Few study provide a clear picture of what specifically constitute collaboration in a construction project in the existing literature and the practical approach. Limit research focus on developing a collaboration theory in construction management. The advent of Building Information Modeling (BIM) has been proved to be helpful for improving project coordination and productivity. However, widely adoption of BIM does not change the fragmented nature of construction sector. An understanding of how to promote such collaborative relationships in BIM enabled projects is crucial to achieve the full potential of BIM. By analysing the characteristics of collaboration from a management perspective and investigating current BIM implementation strategy, this research develops a conceptual model of collaboration in BIM enabled projects and identifies main factors of collaboration. The model categorizes collaboration into three dimension, they are collaboration team characteristics, collaborative environment, and collaborative process. Model also presents high level of collaboration can result better project outcomes and participants satisfaction. This model can be generalized to construction sector and standardized to collaborative process for future BIM implementation.published_or_final_versio

BIM communication waste

Developments in Information and Communication Technology can bring about significant improvements in the efficiency of the Architecture, Engineering and Construction and Facilities Management industry. Building Information Modelling (BIM), is a term which encompasses a type of software but more importantly a set of processes which, at their core, support an approach for integrated project delivery enabled by interoperable software systems. The last three years have seen intensified and coordinated adoption of BIM in the UK mainly as a result of the mandate of the UK government. One facet of these developments is the growing need for BIM collaboration tools which can interoperate effectively with the various BIM software systems, support the required standards and codes of practice and provide for requirements of construction project information production and management such as model-based workflows, model-based communication, model-based procurement, role-based data access and role-based privileges. The pre-requisites for collaboration can be broadly divided into two categories: (1) coordination of information and responsibilities, and (2) communication. This research recognizes the strong focus of recent and ongoing efforts to provide for coordination and aims to support the communication aspect. Additionally, successful collaborative practice results from (1) the "softer" or "human-aspect" issues: collaborative culture, software training and adherence to protocols as well as from (2) the provision of appropriate, intuitive and configurable collaboration tools and, more generally, digital collaboration environments. This research focuses on the latter. Despite efforts from a variety of software-as-a-service (SaaS) collaboration tool vendors to achieve dominance in the market, there is still uncertainty as to what type of solutions would best support BIM collaboration. Additionally, there is considerable variation in software configurations and a lack of a universally applicable method for evaluating the communication capabilities of BIM collaboration tools in a meaningful way. Vendors lack a robust conceptual framework to guide the long-term development of their tools and evaluate them. The process of requirements engineering, which in this context involves a diversity of stakeholders and involves projects at different BIM maturity levels would benefit significantly from a robust, context-specific conceptual model-ontology. The aim of this research is to produce a context-specific conceptual model-ontology which can support the discourse of requirements engineering and provide a robust and widely applicable framework for evaluating the communication capabilities of BIM collaboration tools. It is anticipated that this would help reduce BIM communication waste . To meet this aim, BIM collaboration tools were studied from five perspectives: 1.Users: their opinions, requirements and requests were collected through an online questionnaire survey. 2.Vendor: their perspective was captured through semi-structured interviews. 3.Schemata for interoperability: effectiveness of tools and schemata was evaluated through analysis of software by data fidelity study and scenario-based testing. 4.Tool use: patterns of digitally-enabled communication were explored through an analysis of communication data and meta-data collected from a collaboration tool. 5.Tool improvement: a successful approach in improving a collaboration tool was examined through the development of a context-specific requirements engineering process. This process was evaluated through semi-structured interviews with collaboration tool implementation consultants. Each perspective helped produce more specific requirements from the model as well as elements of the model itself. The end result was the Model for communication waste in BIM process interactions (WIMBIM). WIMBIM has the BIM process transmission as the fundamental unit of analysis and focuses on BIM communication waste and how it results from sub-optimal collaboration tools and schemata. The ultimate purpose of WIMBIM is to support the development of technology which would reduce this waste. This model was converted into a communicable format and was related to BIM standards to aid contextualization and gap identification. To evaluate the validity and utility of this model, interviews with BIM experts were conducted, and the proposed model was found to be a valid approach to address aspects of BIM waste, which is not usually examined and could potentially complement the existing model for BIM maturity. Additionally, the model provides a useful lens for further academic research into BIM collaboration tools

Using the BIM collaboration format in a server based workflow

12th International Conference on Design and Decision Support Systems in Architecture and Urban Planning, DDSS 2014 This paper describes the research and development of a server based BCF workflow and open source BCF server software. BCF is short for "BIM Collaboration Format" and is an open standard to communicate about the ‘issues’ of a BIM model during its design cycle. Essentially, a BCF issue holds a description of the issue, a status, links to a BIM model and objects, a picture of the issue and a camera orientation. The BCF standard is based on file exchange. BCF issues are packed into a ZIP file (.bcfzip) and sent to project partners. This paper, however, describes the use of the same BCF in a centralized online setting. An open source BCF server was developed, and integrated with an online 3D viewer and BIMserver. Through the BCF server it has been shown that project partners have been able to create issues, manage them online and evaluate them in context of the actual BIM model. Research questions investigated within this project included whether the BCF format is capable of describing the status of building objects in addition to merely describing their issues and to what extent the XML based BCF schema proved to be suitable for a more centralized online storage paradigm. A case study was conducted in order to investigate a suitable workflow for a collaborative design project that involved the online sharing of BIM data, issues, and status. This paper describes the project, the creation of the BCF server, the case study and reports on the results

Making Sense of Multi-Actor Social Collaboration in Building Information Modelling Level 2 Projects: A Case in Malaysia

Despite the diversity of thinking among the scholars on building information modelling (BIM) collaboration, there is a paucity of studies that capture the dimension of social collaboration in BIM projects. This study attempts to develop a comprehensive understanding on the key attributes of multi-actor social collaboration in BIM projects through the experience of practitioners in BIM-Level 2 construction project. The success of multi-actor social collaboration has been investigated through structured interviews with 22 BIM practitioners in a BIM-Level 2 project based on an established theoretical framework of social collaboration. The findings indicted that relationship-oriented attributes; relational contracts BIM execution plan; guideline, standard and work process manual approaches; employer information requirement (EIR); understanding roles and leadership; commitment from top management; resources; training, team building workshop and awareness program; coordination; and understanding on the theoretical knowledge of BIM are of importance towards multi-actor social BIM collaboration. This study acknowledges that the success of multi-actor social collaboration was influenced by the consolidation of many attributes, and it extends the dominant relationship between related attributes for multi-actor social collaboration based on the "best practice approach", which includes dominant-centric attributes (i.e., behaviour formation, procurement model and support principles). This research contributes to the body of BIM knowledge in the construction domain by focusing on what it takes to achieve greater social collaboration in BIM Level 2 projects

BIM implementation in architectural practices : towards advanced collaborative approaches based on digital technologies

We are at a stage where Building Information Modelling (BIM) has reached a maturity level to be widely adopted by the professionals and organizations within the Architectural, Engineering and Construction (AEC) industry. An industry which is highly fragmented and not advanced in terms of digitalization, making an effective collaboration hard to achieve. The advances in Information and Communication Technologies (ICT) have brought about the promise of improving collaborative procedure in a wide range of industries. The widespread adoption of BIM has paved the way for the introduction of ICT within the AEC sector. The reported benefits of BIM imply on its potential for contributing to a successful inter-disciplinary collaboration. This calls for attention from architects who shall consider how BIM allows the architectural practices to operate in truly novel ways to achieve new building efficiencies and organizations. This research was designed to investigate the crucial factors for an effective collaboration based on advanced ICT and enabled by BIM with respect to architectural practices. An effective inter-disciplinary collaboration allows architects as the authors of the projects to oversee the development and delivery of the projects more consistently with their design intends. The concerns about the move towards adopting BIM by architectural firms were reviewed and its influential factors and barriers were discussed. As we read about it, BIM is indicated by different terms to describe its essence: ‘’BIM methodology’’, ‘’BIM technology’’, ‘’BIM process’’, ‘’BIM systems’’ and etc. However, none of these terms can include all aspects of BIM. The term ‘’ecosystem’’ was adopted to describe the nature of BIM and the reason for which is described in this work. To further constitute the BIM ecosystem, its dimensions of People, Products and Processes were presented in detail with respect to collaborative procedures. It included the delineation of a number of BIM policies and protocols, tools and technologies, roles and skills which are all related to and suitable for architectural practices in their interdisciplinary collaboration. Through three case studies, the research questions and hypothesis were put into investigation. Based on the idea of change management and the socio-technical nature of BIM collaboration, a qualitative research approach was adopted. Various techniques were used to gather information to be analyzed through a coding process of the qualitative data. The codes were interpreted as the factors influencing collaboration and were grouped to form the crucial concepts contributing to effective BIM-enabled collaborative procedures. It was revealed that the “joint decision making” factor is the most crucial one in this respect followed by “collaboration involvement” and “interoperability”. These findings were based on the frequency of the codes related to these factors in the data analysis. The crucial concepts in BIM-enabled collaboration were revealed to be “collaboration conditions” followed by “software capacity” and “human resources organization”. The findings confirm the research hypotheses that BIM implementation asks architects to assume a leadership role in collaborative procedures and that it allows for the integration of ICT into the technological pipeline of architectural practices. However, the validity of the two hypotheses is subject to certain conditions that are discussed in this work. The research finds the area of BIM education a place of great interest for future research work as the factor of “training” has a great influence on the overall success of BIM-enabled collaboration. Furthermore, it was revealed that the crucial factor of “interoperability” needs more attention from both industry and academic sectors. The impacts of BIM implementation on existing and emerging roles within the industry is another area of great interest for future works and research.Estamos en una etapa en la que Building Information Modeling (BIM) ha alcanzado un nivel de madurez que será ampliamente adoptado por el Profesionales y organizaciones dentro de la industria de Arquitectura, Ingeniería y Construcción (AIC). Una industria que es altamente fragmentado y no avanzado en términos de digitalización, lo que hace que una colaboración efectiva sea difícil de lograr. Los avances en las Tecnologías de la Información y la Comunicación (TIC) han traído la promesa de mejorar la colaboración Procedimiento en una amplia gama de industrias. La adopción generalizada de BIM ha allanado el camino para la introducción de las TIC en el sector de la AIC. Los beneficios reportados de BIM implican en su potencial para contribuir a un éxito interdisciplinario colaboración. Esto requiere la atención de arquitectos que deben considerar cómo BIM permite que las prácticas arquitectónicas operen en formas verdaderamente novedosas para lograr nuevas eficiencias de construcción y organizaciones. Esta investigación fue diseñada para investigar los factores cruciales para una colaboración efectiva basada en TIC avanzadas y habilitado por BIM con respecto a las prácticas arquitectónicas. Una colaboración interdisciplinaria efectiva permite a los arquitectos como autores de los proyectos para supervisar el desarrollo y la entrega de los proyectos de manera más coherente con sus propósitos de diseño. Se revisaron las preocupaciones sobre el movimiento hacia la adopción de BIM por parte de las empresas de arquitectura y sus factores influyentes y Se discutieron las barreras. A medida que leemos sobre esto, BIM se indica mediante diferentes términos para describir su esencia: "metodología BIM", "Tecnología BIM", "Proceso BIM", "Sistemas BIM" y etc. Sin embargo, ninguno de estos términos puede incluir todos los aspectos de BIM. El término "ecosistema" se adoptó para describir la naturaleza de BIM y la razón por la cual se describe en este trabajo. A más constituyen el ecosistema BIM, sus dimensiones de Personas, Productos y Procesos se presentaron en detalle con respecto a procedimientos colaborativos. Incluía la delineación de una serie de políticas y protocolos BIM, herramientas y tecnologías, roles y habilidades que están relacionadas y son adecuadas para las prácticas arquitectónicas en su colaboración interdisciplinaria. A través de tres estudios de caso, las preguntas de investigación y la hipótesis se pusieron en investigación. Basado en la idea de cambio. La gestión y la naturaleza sociotécnica de la colaboración BIM, se adoptó un enfoque de investigación cualitativa. Varios se utilizaron técnicas para recopilar información para analizarla a través de un proceso de codificación de los datos cualitativos. Los codigos fueron interpretados como los factores que influyen en la colaboración y se agruparon para formar los conceptos cruciales que contribuyen a la eficacia procedimientos colaborativos habilitados por BIM. Se reveló que el factor de "toma de decisiones conjunta" es el más crucial en este sespeto seguido de "participación colaborativa" e "interoperabilidad". Estos hallazgos se basaron en la frecuencia de códigos relacionados con estos factores en el análisis de datos. Los conceptos cruciales en la colaboración habilitada por BIM se revelaron como "Condiciones de colaboración" seguidas de "capacidad de software" y "organización de recursos humanos". Los hallazgos confirman la investigar las hipótesis de que la implementación BIM les pide a los arquitectos que asuman un papel de liderazgo en los procedimientos de colaboración y que permite la integración de las TIC en la línea tecnológica de las prácticas arquitectónicas. La investigación considera que el área de educación BIM es un lugar de gran interés para futuros trabajos de investigación, ya que el factor de "capacitación" tiene un gran influencia en el éxito generalPostprint (published version
