Hvad indeholder fagområdet ”IT i byggeriet” ? Kjeld Svidt  Institut for Bygningsteknik  Aalborg Universitet Håndtering af information i hele byggeprocessen - planlægning, analyse, design - opførelse - drift Problemstillinger vedr. kommunikation mellem aktører - personer - organisationer - programmer

Informationshåndtering Kjeld Svidt  Institut for Bygningsteknik  Aalborg Universitet Indsamling, generering Bearbejdning Lagring Transport Præsentation, anvendelse

Eksempler på typer af information Kjeld Svidt  Institut for Bygningsteknik  Aalborg Universitet Grundlag for udførelsen – detailtegninger – monteringsvejledledninger – love og regulativer osv Løbende kommunikation under udførelsen – mødereferater – fotos – s – telefonsamtaler Til brug ved fakturering – timeregistrering – materialeorbrug

Future Building Industry Knowledge Management Systems – BIKOM Gennem de seneste år er web baserede portaler for dokument og tegningshåndtering, og til dels til støtte for handel med fysiske og digitale komponenter, blevet tilgængelige såvel internt i virksomhederne som eksternt mellem virksomhederne. De seneste års udvikling indenfor ICT giver nu mulighed for at opbygge næste generation af portaler eller vidensknude- punkter. Disse kan være horisontalt orienterede og bygge bro mellem videndomæner og/eller specialiserede mod forskellige dele af byggeprocessen. Den horisontale orientering muliggør videndeling på tværs af traditionelle fagområder indenfor byggeprojekter og virksomheder.

IT-CODE System Architecture Knowledge Nodes (projects, team, suppliers,…) General (RDF, XML, logics) Conextt specific (digital process manager) Artefact access, User Environment Artefact control Analyses/ syntheses tools (From Lai Y-C, Christiansson P, Svidt K, 2002, ”IT-CODE -IT in Collaborative Building Design”) Using RDF, RDFS, XML, XMLSchema,

SEMANTIC WEB The Resource Description Framework (RDF) - developed by the World-Wide Web Consortium (W3C) - provides a framework for metadata interoperability across different Internet based resource description communities with focus on semantics rather than meta data syntax and structure. The semantic webs (Berners-Lee, et al., 2001) will use eXtensible Markup Language (XML) RDF, and Ontologies (with taxonomy and a set of inference rules) as basic building substances. RDF will allow the resource description communities to primarily focus on the issues of semantics rather than the syntax and structure of metadata). Schema defines the meaning, characteristics, and relationships of a set of properties.

What is Virtual Reality ?  Presentations that take place at the VR-Centre ?  Convincing your senses that something virtual is real  Realistic visualisation of phenomena which are difficult to see in reality (e.g. airflow)

Virtual Reality may include the following elements:  Stereo viewing (different pictures for right and left eye) Passive (polarized or colour filter) Active (shutter glasses)  A certain degree of immersion Wide screens, power walls Large curved screens CAVE Head mounted displays  Realtime interaction with the model/database Mouse or keyboard Tracking of persons or interaction devices Haptic devices

DIVERCITY - Distributed Virtual Workspace for enhancing Communication within the Construction Industry EU IST The objective of the project is to produce a prototype virtual workspace that will enable the three key phases (client briefing, design review, construction) to be visualized and manipulated, and to produce a set of VR tools that aid the construction design and planning process. The Divercity project has 10 partners in 5 EU Countries
