Graphisoft Australia migrating to Central Innovation
All ARCHICAD and extensions products by Graphisoft will soon be accessed at www.centralinnovation.com. The mega site will showcase the best of breed design software for the architectural and manufacturing industries. You will also have immediate access to training, support, hardware solutions, and systems integration solutions for all your design needs. Stay tuned for the new 3D design mega website!
Even at the smallest scale – AEC projects are endeavors rife with serious collaboration challenges. Successfully completed building projects are the result of the collaboration of different teams of building professionals such as architects, engineers and a general contractor and sub-contractor. These teams more often than not have divergent “trade” priorities and belong to independent organizations with opposing interests.
As a result, these are the collaboration issues present in most AEC projects:
Sticking to the technical level, coordination between the different trades has gone through a lengthy evolution. Traditionally, different trades submitted full printed documentation sets at the different stages of the design process and used light-tables to try and coordinate the various building structures and building systems. This approach is still popular today with paper’s digital equivalents: the 2D DWG and PDF-based collaboration workflows.
With the advent of model based design (BIM), design collaboration entered a new era with the much richer building information model data. With BIM models, demand has increased for true model based collaboration. Two fundamentally different approaches emerged as one known as the “platform” approach where collaboration happens using the different branches of the same software solution; the other, known as the “open” approach, where different software solutions form the basis of model-based collaboration.
The traditional approach to interdisciplinary collaboration basically means any form of 2D collaboration including paper, DWG or PDF or any other 2D forms. This approach can be characterized as follows:
One of the prominent approaches to model-based (BIM) collaboration is the platform approach where the different branches of the same product family are used to provide binary compatibility. This data-level compatibility on its own may leave serious gaps in the coordination workflow:
The other prominent approach to model based collaboration promotes open collaboration workflows where complex company and project structures are fully appreciated. This approach elevates the conversation from the data level to the workflow level making data what it is: a medium or vehicle of high-level information. With this approach, project participants can be selected based upon their professional expertise and not a particular software being used.
The only goal of the OPEN BIM movement is to promote open collaboration workflows for better-coordinated projects. This goal is primarily achieved through a globally common, publicly achievable OPEN BIM branding supported with clear definitions, specific requirements and best practices to help implementation.
The OPEN BIM movement was launched by two software vendors – Tekla and GRAPHISOFT and is supported by various organizations. At the same time, OPEN BIM is not an exclusive club. Instead, it is an inclusive movement welcoming any organization in the AEC industry that is ready to support the overall goals and fulfill the agreed set of requirements.
The OPEN BIM movement offers various benefits to the different types of organizations (see below) but provides the following toolkit to anyone joining the movement:
Organizations all over the world have been encountering the collaboration issues detailed above. Different collaboration strategies have been used to address them, including in many cases open collaboration workflow. At the same time, open collaboration practices were used more as a necessity in a plural AEC environment rather then an intentional strategy to deliver better-coordinated projects.
The OPEN BIM movement elevates open collaboration to a strategic level where like-minded AEC professionals build upon their plurality to deliver better coordinated building projects, with less errors and in higher quality.
Should you or your organization share these values, joining the OPEN BIM movement not only provides you with guidelines and best practices but also with common branding and international visibility to leverage and maximize the value of your projects. OPEN COLLABORATION → BETTER BIM!
The OPEN BIM program welcomes not only software vendors but Organizations and Building Projects of the AEC industry as well. The OPEN BIM™ logo is a guarantee that a software solution, a design or engineering practice or building project fully meets the requirements of open collaboration. Participants in the OPEN BIM Program agree to fully comply with the following requirements respective to its role in the AEC industry:
Organizations in the AEC Industry
Building Projects in the AEC Industry
AEC software vendors’ primary benefit in joining the OPEN BIM movement is that they can offer their clients open collaboration workflows that provide a competitive advantage on local AEC markets. The OPEN BIM branding guarantees that the solutions developed by participating vendors comply with the OPEN BIM requirements and do not impose unnecessary limitations on AEC practices choosing their software to collaborate with any other practices.
In contrast to CLOSED (or “proprietary”) BIM the OPEN strategy offers great benefits to building professionals:
Building projects themselves are products with their own market. With diminishing differences in building materials and technology, in addition to a building’s genuine design, additional labels such as “sustainability” can greatly increase the potential project value on the market. The OPEN BIM movement offers projects a label with very positive associations. Future owners, operators and tenants of such buildings will have better chances to further utilize the digital building model if it was created using the OPEN BIM approach in the first place. This translates to an increased ROI with the continuously elongated building cycles.
OPEN BIM is supported by various organizations that host related information in their own domains. To find some relevant information you may also choose to visit any of the following pages:
