INTERNATIONAL ALLIANCE OF INTEROPERABILITY (IAI)
The International Alliance for Interoperability (IAI) was founded in 2001, and renamed ‘building Smart™ in 2007. Originally formed as a collection of international ‘chapters’, it was collectively responsible for the Building Smart™ concept and the ISO standard of Industry Foundation Classes (IFC) for Building Information Models.
BUILDING SMART™
Building Information Modeling (BIM) was introduced nearly ten years ago to distinguish the information rich architectural 3D modeling from the traditional 2D drawing. BIM is a building design methodology characterised by the creation and use of coordinated, internally consistent computable information about a building project in design and construction. BIM makes a reliable digital representation of the building available for design decision making, high-quality construction document production, construction planning, and performance predictions, and cost estimates. Having the ability to keep information up-to-date and accessible in an integrated digital environment gives architects, engineers, builders, and owners a clear overall vision of all their projects, as well as the ability to make informed decisions faster.
| BIM has been promoted as the solution to reduce waste and inefficiency in building design and construction and today, it’s hard to peruse a professional journal without reading about BIM, and software vendors and consultants continue to promote it as the answer for improving efficiency of the entire construction industry. Customers using BIM will save time and money, see fewer design errors, experience improved productivity, and have access to new business opportunities. BIM is not a technology itself, but it does require suitable technology to be implemented effectively.
IFC AND IDM IFC is a file format for the exchange of intelligent and object oriented information with other platforms supporting the standard. Building Smart™ delivers IDM (Information Delivery Manuals), the ISO standard for contractual information flow between key processes and stakeholders in the construction industry. IDM is integrated with Government and Industry systems such as e-submission, code checking, standards and knowledge base.
BIM PPROCESS As the AEC industry evolves and adopts process oriented planning and production methods, similar to the automotive and aerospace industries, more construction companies wish to participate in BIM projects by facilitating the central 3D geometry. With the BIM process, all data from the design and construction phase is stored in an intelligent dynamic 3D model. Architects, building services specialists, engineers, facilities managers (FM), building users and owners can access and use this data to suit their own specific demands. Once stakeholders in the design process have added their information, and the engineering phase has reached completion, the information is then read back in so that detailed iformation can be harvested from the 3D model.
BUILDING SMART™ ADOPTION The success of building SMART™ is such that an ever increasing number of software publishers have implemented the IFC standard, which provides connectivity to calculation, tender, building services, energy analysis, environmental analysis and sustainability systems.
INDUSTRY BENEFIT Because IFC is in the public domain, versus ownership by a single software vendor, the AEC industry is now able to produce building models allowing all participants in the value chain to benefit.
