Who is BARBi ? BARBi is a joint initiative for the Norwegian building industry with members from ü Norwegian council for building standardisation, Norwegian building research institute, associations for Engineers, Architects, Owners and Contractors. Associations producers of materials, building products and product catalogues. BARBi cooperate internationally with ü STABU Nederland, Building Research Establishment BRE, International Construction Information Society (ICIS), International Alliance for Interoperability (IAI) and EPISTLE Lars Bjørkhaug, Norwegian Building Research Institute

The BARBi project – timeline – ü January 1998 – August 1998 Study of the ”state of the art” in product modelling in the building industry ü September 1998 – January 1999 Test of EPISTLE snapshot E (POSC/CAESAR) ”the Wall test case” February 1999 – May 1999 New evaluation based upon the results of the test case May 1999 – October 1999 Establishing a subset of EPISTLE v. 3. 1 for the building industry. November 1999 – October 2000 Participating in the development of ISO/PAS 12006 -3 and Ifc 2 x October 2000 – February 2001 Establishing a test version of BARBi. March 2001 – December 2001 Development of tools and establishing founding for further projects. Test of compatibility with EPISTLE snapshot E-, and Lexi. Con content. March 2002 – > Full scale test of the library. Connecting briefing, calculation and specification applications with knowledge bases, building codes and product catalogues. ü ü ü Lars Bjørkhaug, Norwegian Building Research Institute

What is BARBi ? A conceptual. . . object oriented. . . language neutral. . . reference data library The Norwegian version of a common Reference Data Library based upon the framework of ISO/PAS 12006 -3 Lars Bjørkhaug, Norwegian Building Research Institute

What is BARBi ? Conceptual . . because BARBi describes objects from what they are, independent of use and time, and not from what they are named or classified as. NS 3451 ”Building parts” NS 3420 ”Building specifications” ”Building product catalogue” building, outer wall, inner wall, door, outer door, inner door, sliding door, cladding, outer cladding, inner cladding, surface, inner surface, outer surface, inner surface, artefact, interior. . . Lars Bjørkhaug, Norwegian Building Research Institute

What is BARBi ? Object oriented. . because it puts the object (concept) in the centre and study its properties and relations to other objects. inner door is a type of door fire door is a type of fire escape route door consists_of door is part of door leaf door frame doorway horizontal light-opening for door can be building product is a type of is part of consists_of is a type of escape route door sill opening in wall relates to inner door outer door sliding door consists of rotating door strongroom door with of escape route sliding door leaf sliding door frame Lars Bjørkhaug, Norwegian Building Research Institute

What is BARBi ? Language neutral. . because one object can have several names in the same language bjelke beam truss balk ligger Lars Bjørkhaug, Norwegian Building Research Institute

What is BARBi ? Language neutral. . because one name can refer to several objects pump function a pump in a functional description physical object a mounted pump in a plant activity/prosess to pump something Lars Bjørkhaug, Norwegian Building Research Institute

What is BARBi ? Language neutral. . because what a dictionary gives as a translation of a word in one language not necessarily refers to the same object in another language. dørblad door-set door Lars Bjørkhaug, Norwegian Building Research Institute

What is BARBi ? Reference Data Library ü Linking standards, classification systems and their definitions. ü Having globally unique ID’s for every concept in the library. ü Providing multiple classificationand specialisation hierarchies for any concept Architect Specification Civil User tool CAD engineer tools Knowledge Proj. Eng, tool base library Economy Common Project Proj. Owner Contractor tools Model library Knowledge Price Building texts base catalogue Eng. tool Sub. FM contractor Knowledge Productbase El. engineer catalogue Proj. library ISO/PAS Lars Bjørkhaug, Norwegian Building Research Institute

Key principles for population of BARBi ü Every object shall be self-contained (consistent and computer sensible) ü All properties are directly associated to the object (concept) ü Properties shall have meaningful names ü A supertype concept might represent any of it’s first level subtypes. ü All concept shall be class level concepts ü All concepts shall be public domain Lars Bjørkhaug, Norwegian Building Research Institute

What can BARBi do for the building industry? Give precise and exact definitions of objects, properties and relationships. I. e. What do we mean by ”width” and ”height” for a door? ü depends on who is using the concept, and in which context it is used. ü depends on when, in an object’s lifetime, the concept is used. ü depends on which classification we refer to. Lars Bjørkhaug, Norwegian Building Research Institute

What can BARBi do for the building industry? Give precise and exact definitions of objects, properties and relationships. in BARBi you will find: ü all known properties for objects with explicit names ü several types of relationships between objects, properties, activities, units and references. ü references to known standards and classification systems ü a global unique ID and a set of language-dependent names and definitions, for every concept in the library Lars Bjørkhaug, Norwegian Building Research Institute

Ongoing full scale test project Objects and object templates using ISO/PAS 12006 -3 Example of types of information flow between applications and different sources of information. An RDL Object is a language neutral object with unique ID’s for all properties and relationships independent of use and time.

Ongoing full scale test project The four layers of the reference library ISO/PAS 12006 -3 Framework for object oriented data exchange. EXPRESS data model giving the framework for reference libraries. Rules for population of Reference Data Libraries based upon ISO/PAS 12006 -3 I. e EXPRESS rule schema Reference Data Libraries Language independent reference BARBi objects (RDL object) and relationships. Norwegian names and descriptions with unique ID’s. Lexi. Con Dutch names and descriptions …… Names and descriptions in other languages Template generators, APIs for storing / reading RDL objects Templates (mapping) Provide mapping between neutral objects and different ways to represent/present them Ifc template Ifc-RDL mapping Product template Search template Product properties. .

Possible scenarios for the use of ISO/PAS 12006 -3? In connection with classification systems and paper standards ü Automatic translation of classification systems ü Providing navigation (query and update) in reference data through established hierarchies ü Translation of ISO/PAS 12006 -3 objects to classification codes and vice versa. ü Mapping between classification systems in different countries Lars Bjørkhaug, Norwegian Building Research Institute

Possible scenarios for the use of ISO/PAS 12006 -3? For product and object catalogues ü Offering complete conceptual object definitions for any building product independent of time and use ü Automatic translation of product catalogues between different languages ü Give standard input/output interfaces (views/templates) for queries in product catalogues Lars Bjørkhaug, Norwegian Building Research Institute

Possible scenarios for the use of ISO/PAS 12006 -3? In connection with knowledge databases and best practise systems ü Offering neutral ways of structuring knowledge ü Using conceptual objects to interface knowledge databases. Lars Bjørkhaug, Norwegian Building Research Institute

Possible scenarios for the use of ISO/PAS 12006 -3? In connection with IAI and IFC ü ISO/PAS 12006 -3 provides a solution for continuing standardisation beyond the international level (IAI) ü Multi-lingual support for IFC concepts (object types and property sets) ü Offer templates for creation of IFC property sets ü Supplying language neutral IFC property sets from ISO/PAS compatible product and object catalogues. ü Offer mapping between IFC and national classification systems Lars Bjørkhaug, Norwegian Building Research Institute
