    • Why eConstruct? Building & Construction Industry
      • Each country has its own
      • Language
      • concepts
      • Standards
      • Operates locally
      - Act as an European Player - Operate across National boundaries
    • Why eConstruct? Contractor/ sub contractor
      • Procure / Bid
      • Locally
      • Difficult to survey market
      • Search in many portals with different structures and languages
      • Procure / Bid
      • Europe-wide
      • Easy to survey market
      • Search in different portals with same structure in one‘s own language
    • Why eConstruct? Manufacturer or Supplier
      • Sell - Locally in different languages
      • To a fragmented Industry
      • O ffered through many portals with different data structures (catalogues)
      • Sell
      • Europe-wide
      • automatically translated
      • Through one channel
      • Offer through many portals in one data structure (catalogues)
    • Why eConstruct? Portals
      • Provide Information - Locally
      • To a fragmented Industry
      • Each product in its own data structure (catalogues)
      • Provide Information
      • Europe-wide
      • Easy to maintain in many languages
      • Through o ne data structure (catalogues)
    • Why eConstruct? Contractor Supplier Portal Supplier Contractor Portal Portal Contractor Supplier €
    • Therefore eConstruct € Contractor Supplier Portal Product Models Internet Lack of Standards bcXML Digital Catalogues
    • What Industry needs
      • Open communication for catalogue information
      • Agreement needed on these catalogue ‘Objects’ and their ‘Properties’
      • Require a ‘flexible’ structure – that also supports catalogue specific information
      • To be able to find things and compare them
      • Inexpensive and easy to use
    • Goal
      • Develop
      • Implement
      • Disseminate
        • a new Communication Technology
        • tailored to the Building and Construction Industry

    • Modelling Dictionaries & Taxonomies
        • Dictionaries
          • Strings/words: isolated terms for objects, properties etc.
        • Taxonomies
          • interrelated objects & properties
            • objectification (from strings to things)
            • specialisation
            • object <> property connection
