5 MAIN AREAS FOR IFC FOR INFRASTRUCTURE Road and Rail Construction, Bridges, Tunnels, Geological, Utilities Defining major use cases for infrastructure

6 Identified use cases in building construction Design Procure Assemble Operate Existing Conditions Modeling Energy Analysis Product Library Construction Systems Design Space Asset Site Analysis Structural Analysis Manufacturers Information Phase Planning (4D) Building Maintenance Scheduling Security / Key Architectural Programming Lighting Analysis Product Selection Commissioning Way finding Telephone Quantity Take Off Mechanical Analysis Perform Procurement Code Validation FM Documentation Disaster Planning / EM Preparation Cost Analysis Other Engineering Analysis Digital Fabrication Record Modeling Maintenance & Repair Information Life Cycle Costing Building System Analysis Consistency Control Specification Production 3D Coordination Design Authoring & Briefing 3D Control & Planning Engineering Analysis Design Reviews

7 Potential use cases in infrastructure Design Procure Construct Operate Land Use and Transportation Planning Product Master Data Virtual Project Scheduling Virtual Work Planning Road Toll and Facility Public Information and Communication Enterprise Buying Virtual Lift Planning Visual Progress Reporting Bridge Maintenance Emergency Response and Repair Traffic Impact Simulations Product Inventory Field Survey Site Logistics (JIT) Transportation Systems Water Mitigation and Planning Engineering Analysis Product Vendor Geospatial Issue Tracking Equipment Traffic Volume Simulations Disaster Planning Target Quantity Tracking Supply Chain Equipment Telematics Product Inspection and Testing Event Planning Maintenance & Repair Information Constructability Reviews Business to Business Transactions Work Zone Safety Planning Virtual Cost Reporting GIS Asset Tracking 3D Coordination Material Tagging and Tracking Equipment Machine Control Mobile Progress Claiming Rule-based Model Validation Automated Procurement Maintenance of Traffic Field Design Changes Quantity Take-Off Material Testing and Analysis Quality Issue Tracking and Reporting Thanks to Tom Harter

8 High value use cases can be dealt with today Design Information Delivery Manual Minimum exchange requirements for identified use case 3D Coordination Quantity Take-Off

10 IFC2x3 CivilProxyView mvdxml

11 IFC2x3 SimpleProxyView (early example)

12 IFC4 providing the stub for infrastructure Supported definitions Mapping to GIS coordinate systems Division between site and terrain Non-building related spatial elements Geographic features (posts, signs, etc.) Civil engineering related elements Non-planar surfaces... New classes in IFC4 IfcProjectedCRS, IfcMapConversion IfcSite (updated) IfcSpatialZone IfcGeographicElement IfcCivilElement (stub) IfcAdvancedBrep... Decision and RFI tracking XML based transactions downstream BCF 2.0 (already available today) Simple ifcxml4

13 IFC5 scope of new extensions Gradual development of sector specific IFC for Infra extensions Bridge, road, rail, tunnel, etc. Based on common resources (alignment, geotechnical, earthwork, etc.) IFC5 Infrastructure HVAC domain extension Bridge domain extension Architecture domain extension Road domain extension shared building element and spatial structures Core shared infrastructure element and spatial structures common extensions common resources

14 Open Standard Roadmap for Infrastructure Infrastructure VDC Software : Autodesk / Bentley / Trimble / Intergraph (and others) for now proxy IFC upcoming IFC4 stub final solution IFC for Infra obtain, visualize and interpret quantities, material and other construction data (EDM) ERP Solution SAP

15 Conclusions 1. Identify the use cases for infrastructure 2. Identify the information requirements (IDM) 3. Map to IFC schema (check coverage in IFC2x3, IFC4) 4. Identify scope for IFC extensions (gap analysis) 5. Develop the IFC extensions 6. Verify IFC extensions against use cases 7. Support implementation and finally certification Stay within the original scope for BIM/VDC, collaborate with others
