  5. Workflow and Use Case Exchanges coordination with architect Exchange with structural engr coordination with GC Logistics coordination Plant management coordinaiton Within workflows, identify important data exchanges

  6. IDM Exchange Specification All exchanges identified in process models Identify all precast information: Project; precast parts and components, structural, reinforcing, control data Identify relevant attributes Required? range of variation These specifications are called the IDM Requirements

  7. Notion of Concepts slab assembly wall panel location material shape mark, sequencing, filed location components material location shape hollowcore material mark, sequencing, field location shape components reinforcing connections embeds connections reinforcing Concepts are Information Classes Information content may vary, but the information structure may be shared:

  8. Notion of Concepts slab assembly wall panel location material shape mark, sequencing, filed location components material location shape hollowcore material mark, sequencing, field location shape components reinforcing connections embeds connections reinforcing Concepts are Information Classes Information content may vary, but the information structure may be shared: implemented in translator once, validated and certified

  9. Top-Level Concepts Precast-Specific Concepts

  10. Types and Instances in the Precast MVD Concept Definition Objectified Relations

  11. Mapping from IDM to IFC Bindings & EMs IFC Bindings Concepts Exchange Model IDM Requirements

  12. IFC Spatial Structure

  13. Ifc Spatial Hierarchy Objectified relations Space Object carries usage (thus loads)

  14. Ifc Extensibility The IFC is an extensible schema that allows growth and refinement. Each release responds to user input and specialized domains within AEC such as precast The current production release is 2.x3, with 2.x4 in alpha release. The Georgia tech team has identified some extensions needed for precast.

  15. Extensions to Release 2.x4 Extend Standard Beam Types: New definition ::

  16. Extensions to Release 2.x4 Slab Property-Set

  17. Extensions to Release 2.x4 Precast Module ENTITY IfcModule SUBTYPEOF (IfcBuildingElement); END_ENTITY; As is done for all of the other building products, an IfcModuleType entity should also be added. ENTITY IfcModuleType SUBTYPEOF (IfcBuildingElementType); END_ENTITY;

  18. Extensions to Release 2.x4 Precast Profiles Hollowcore

  19. Extensions to Release 2.x4 Precast Profiles Doubletee

  20. Extensions to Release 2.x4 Reinforcing Pattern ENTITY IfcReinforcingPattern SUBTYPEOF(IfcReinforcingBar); BarSpacing : LIST OF [1:?] IfcPositiveLengthMeasure; RowDirection : IfcDirection; END_ENTITY; ReinforcingBarRow 3 ReinforcingBarRow 2 RowDirection ReinforcingBar S3 S1 S2 BarSpacings usable by both rebar and tendons

  21. Extensions to Release 2.x4 Reinforcing Bending Pattern
