GEOMETRIC ENRICHMENT
Durable Architectural KnowledgeDevinder Thapa, Luleå University of Technology
• Data synchronization: two different representations of the same building model can be synchronized using a semi-automated approach
• Difference analysis: deviations between as-planned and as-built state can be highlighted
• Semi-automated indexing: enhancing unstructured point clouds with higher level semantics
• Access copy generation: light-weight representations of gigabyte big point clouds allow easy handling including access via network and visualization on consumer hardware

SEMANTIC ENRICHMENT
Durable Architectural KnowledgeDevinder Thapa, Luleå University of Technology
• Architectural models (2D/3D) and BIM lack semantics, context and are ambiguous.
• Semantic context includes history, material, legal aspects,environment & surrounding infrastructureWeb of data yields lots of relevant information
• Semantic enrichment deals with enriching BIM with related contextual Web data & vocabularies
• Evolution of Web data is inherent problem (crawling and preservation)

PRESERVATION
Durable Architectural KnowledgeDevinder Thapa, Luleå University of Technology
• Ensures that the information is available and useable for the designated community
It addresses the aspects of bit preservation, logical preservation and semantic preservation
