3 But Why and How?

4 A highly precise virtual reality model is being created in parallel with the design of a Norwegian road, to help avoid conflicts in both design and construction. (World Highways 7 January 2008)

5 Case Study: RV 150 Ring 3, Ulven Sinsen Owner: Road Department, Contractor : Veidekke Average cost per change/conflict has been calculated to be about $ 9600 (Norwegian Road Authority) Part 1: VDC model was not used About 250 out of 600 changes were caused by design conflict between domains Additional cost of $ 2.4 mill. (+4,6%) Part 2: VDC model was used There has been almost no design change/conflict on this parcel, E22, Petter Bakke, Veidekke Potential cost savings $ 2.4 mill.

6 Case Study: Gjønnes station Owner: KTP AS, Contractor: Veidekke Total 350 conflicts was found Half of them had not been detected without a VDC model Based on Norwegian Road Authority estimate potential cost savings have been $ 1.7 mill.

7 Case Study: Ring-I Mestari tunnel, Finland Owner: Road Authority, Contractor YIT VDC model for simulating traffic guidance and traffic safety Sequence planning Virtual training and testing Traffic camera placement Sunlight protection Major time savings Delivery 3 months earlier Overall project 1 year earlier Infrastructure construction of the year 2010 award

8 Cost Savings Are For Real (According to studies made by Norwegian Road Administration) Article in Norwegian IT Magazine, November 6, 2013 Article in Danish Engineering Magazine, November 11, 2013

9 VDC Potential in Construction Typical construction additional change orders are about 20% of construction costs By using VDC about 75% of change orders can be avoided Potentially 5-15% savings Almost 0 changes or waiting on site because of design errors VDC may increase design costs but: Better design quality, error free designs Less documents, more digital data Understanding and communication increases More time to study alternative better solutions Affect costs and changes in in earlier phase Less risks, more fluent construction Clearly positive ROI, very good investment Traditional Using VDC Design Construction

10 Norwegian Contractor Comments The 3D models we get for all domains, makes our working day easier and more efficient. There has been almost no design change/conflict on this parcel, E22 Petter Bakke, Veidekke In practise, there are no longer any change/conflict in the design models we get for each domain. We use the models for multiple purpose: Stake out, communication with construction workers to plan todays work etc. We love working this way! Erik Hval Olsen, Veidekke Continuity in production, for all our man and machine AND doing everything just once, is the two most important issues for a cost effective construction. The use of collaboration models on the Marienborg project, did that we actually had almost zero stop at site, caused by errors in design (like collision between domains). We could produce continuously. Bård-Olav Aune, SKANSKA

11 Case Study: Zoo Interchange Pilot Owner: Wisconsin Department of Transportation, USA Input data DGN, DWG, IFC (Utilities, Civil3D, Revit) LandXML (InRoads, Civil3D) Modeling Parametric tools allows automatic utilities modeling from line data Direct links to input data allows automatic model updates when design changes Results Cost effective GIS data modeling in 1 day Immediate updates directly from Civil3D Design system independent via open standards Opportunity: 5% savings from 1.7B$ estimated construction cost would be 85M$!

12 VDC Benefits ROI/CBA Owner: Wisconsin Department of Transportation I-94 Mitchell IC Construction Project-$294.4 m Field Issues - $22.2 m (669 DINs/CCOs) (~ 7,5%) GN-General: 30.5% (148-$6.8 m-30.5%) ($45,674 per issue) RD-Roadway/Drainage: 25.5% (66-$5.7 m) ($85,631 per issue) WU-Wet Utilities/Drainage: 11.1% (90-$2.4 m) ($27,120 per issue) BR-Bridges: 8.0% (114-$1.8 m) ($15,557 per issue) NW-Noise Wall: 8.0% (14-$1.8 m) ($125,909 per issue) RW-Retaining Wall: 7.7% (78-$1.7 m) ($21,818 per issue) EW-Earthwork: 4.5% (17-$1.0 m) ($59,220 per issue) EL-Electrical/ITS/FTMS: 2.6% (93-$0.6 m) ($15,557 per issue) TR-Traffic: 2.1% (26-$0.5 m) ($18,174 per issue) SS-Sign Structures: 0.1% (23-$0.02 m) ($738 per issue)

20 Novapoint VDC Explorer Simplified project structure under which all data is imported. Easier to handle large amounts of data. Import standard data formats like LandXML, IFC, DWG, DGN and generic 3d model formats. Object Info window shows selected object properties, coordinates, dimensions etc. Free text search allows users to search objects by properties. Model view with easy navigation makes it easy to get overview of the project and go rapidly into details. Models can be visualized using color coding or by attaching realistic materials to imported model elements. Topics is the center for collaboration. Topics have name, description and attributes. Attributes are used to classify topics for example by priority, responsible, deadline, discipline. Topics can have multiple viewpoints attached which are saved to collaboration server for users to browse without model. Under topic there can be additional comments which form a discussion thread around the topic. 5D simulation tool allows attaching a schedule and cost information into model parts. Supports MS Project. Schedule is linked to clash detection. Value based clash detection finds most important design clashes easier and faster than traditional clash methods. Collaboration is integrated into the model. With collaboration users can attach comments to model or manage model specific tasks. These topics can be viewed with a thumbnail list or as an Excel like table with sorting and filtering tools. Topics are sunchronized between users via VDC Collaboration Server.
