BIM-naar-GIS dataverwerking: linken en visualiseren

385 views

Published on

De juiste informatie uit BIM-modellen kan een grote toegevoegde waarde hebben in het beheer van infrastructuur. Helaas gaat veel informatie verloren gedurende de levenscyclus van een infrastructuurobject. In deze presentatie bekijken we hoe we deze informatie-eilanden kunnen overbruggen door BIM data te linken en te visualiseren. Concreet gaan we in op technieken voor het verwerken van BIM data voor indoor mapping, facility management, issue management, Web visualisatie, en augmented reality apps.

  18. 18. Often information is lost during lifecycle transitions causes: • People: people or organisations do not communicate well information needs • Processes: imperfect handover of information • Technology: differences in systems, standards, and tools BIM-naar-GIS dataverwerking - FLAGIS - 11 December 2018 DESIGN life cycle Informationvalue PLAN CONSTRUCT OPERATE & MAINTAIN DEMOLISH 19
  19. 19. Good information management preserves the value of information no information management: • data must be gathered at the beginning of each phase • data is not linked so less valuable information management: • data is gathered only once • data is validated, linked, transformed, and analysed so that it is remains useful over time BIM-naar-GIS dataverwerking - FLAGIS - 11 December 2018 DESIGN life cycle Informationvalue PLAN CONSTRUCT OPERATE & MAINTAIN DEMOLISH 20
  20. 20. To prevent information loss you need: • Information Management Plan • Object Identification Specifications • Object Type Library (OTL) • Information Delivery Specifications (IDS) • Information system (Common Data Environment) BIM-naar-GIS dataverwerking - FLAGIS - 11 December 2018 21
  21. 21. Information Management Plan • Strategic / tactic level • Roles and responsibilities: Who has ownership?
