What we do New ICT group from 1. january 2005 BARBi Delivery 20th of December 2004!! Interface version 0.8 More work remains Byggforsk Knowledge Base Supplement current version Efficient ways of delivery IFC IFD

What can IFD do? Give multiple names in multiple languages Concepts are classified as objects, activities, properties and units, not as verbs, substantives, adjectives, etc. dør door dørblad A dictionary based mapping does not necessarily refer to the identical concept. door door-set An concept can have multiple names on the same language bjelke truss beam ligger balk pump Activity or process to pump Physical object a physical pump on a plant Functional object a pump as a functional object A name can refer to multiple concepts

One object exist in multiple contexts In a CAD system Properties In a briefing document IFD dictionary Properties Properties In a calculation system Properties In product catalogues Properties In a Facility management system Properties In classification systems Properties For demolition and reconstruction Properties In building specifications Properties

One concept carries the same unique identificatior in every language One object exist in multiple contexts One concept carries the same unique identificatior in every language 78AF4E98C8D4406B873DBB85E1FE7DB In a CAD system Properties In a briefing document Properties BARBi - Norway Properties LexiCon - Nederland Properties In a calculation system Properties In product catalogues Properties NBS - England Properties SDC - France Properties In a Facility management system Properties In classification systems Properties For demolition and reconstruction Properties In building specifications Properties

IFC and IFD for exchange of data IFC and IFD opens for 100% standardisation of exchanged data IFD reference data IFC propertyset Information exchange on IFC format IFC can also exchange self defined data through IFC property-set… Self defined data IFC propertyset IFC ensure that data is exchanged as objects and object properties and not as lines and layers… IFC can only standardise to a level of detail that is internationally agreed about… The properties within an IFC property-set are not always standardised IFC properties are not context independent…

Why is the integration of IFC and IFD important? IFC + IFD enables one common platform for: Knowledge databases Knowledge and rules can be formatted in a way that enables automatic control of selected solutions towards best practice, rules and requirements. Products and product properties carries the identifiers from IFD dictionaries. This allows for searches to be made based upon data from drawings, and specifications. Product databases Project databases Project information from different phases of the project is stored on objects and object properties. Information can be filtered, edited and viewed in multiple ways.

Extended use of IFC and IFD, possible scenarios: Research centres and suppliers of best knowledge: Generic object databases with links to specification sheets and knowledge Object databases with parametrical intelligent objects Predefined solutions to drag-and-drop into CAD or specification software, etc. IFC Automatic control of selected solutions against best practise and regulations. IFC Centralised calculations of environmental impact Calculations of life cycle cost and lifetime prediction Certifications Health and safety evaluation IFC

Extended use of IFC and IFD, possible scenarios: Standardisation- and specification organisations: Mapping between national classification and specification standards and IFC data Control of project data towards standards and specifications. IFC IFC Automatic translation of standards and classification-tables between countries Standardised views of project data through known hierarchies

Extended use of IFC and IFD, possible scenarios: Product model servers (project hotels, project servers) Possibility to exchange and update single objects. No longer need to send the whole drawing layer. History of changes and reason for changes. Possibilities to set access rights for particular actors. One project can be visualised in multiple ways; as drawings, specifications, calculation, estimates, etc. Functional demands, technical solutions and product information stored on the same object. IFC + IFD product model Reuse of information throughout the life-cycle of the building Extracts of essential information from product models; escape routes, room functions, load bearing walls Particular information to and from building authorities Materials and product used Facility management information Guaranties and maintenance information … IFC + IFD product model
