  1. Virtual Design & Construction: 3D Information Modeling Ron Gant, P.E., Bentley Systems, Inc.

  2. The Challenge • Building Information Modeling • CivilInformation Modeling • But really……. Information Modeling

  3. Information Modeling • Everything is an extract of…. • Physical 3D design model • Digital Terrain Model • Plan Set (construction or fabrication) • Quantities • Machine Guidance • Clash detection . . .

  4. Information Modeling • Business drivers for Civil-Transportation • PPP (Public-Private Partnerships) • Design Build • Machine Guidance • Clash Detection • Improved profitability • Life Cycle Management • Construction simulation • Paradigm shift for Civil Engineers • Not just about construction • Life Cycle data management

  5. The Challenge • Vertical modeling in a horizontal world • Technical challenges • Horizontal scale of projects • Grid to ground • Convergence of meridians • Linear stationing vs. grid • State Plan or geodetic vs. local coordinate system • U.S. Survey Foot • One International Foot equals 0.999998 U.S. Survey feet • Professional challenges • No state registration board accepts the model, yet • Paper rules • Model stamping, security Ronald E. Gant 55849

  6. Comparisons Building Advantages Civil Challenges Lots of standards – 50 DOTs Geo-coordination Linear or State Plane Traditional workflows • AIA approved, National CAD Standards • Physical scale • Coordinate systems • Willingness to change

  7. What Makes Civil Information Special • Some cases, Nothing • Drainage • Survey • Site

  8. What Makes Civil Information Special • But working with the DOT • Pay Item Databases

  9. What Makes Civil Information Special • But working with the DOT • Pay Item Databases

  10. Information Modeling Public Involvement InRoads GEOPAK MX Field Reporting Quantities Collaboration Shop Drawings Project Survey / Layout Civil Information modeling Scheduling 3D Visualization Machine Controls External Vendors and Suppliers Constructability Collaboration Field Working Drawings Owner Project Deliverables As-Built Drawings

  11. Things to look for in your Information Modeling Solution • Geo-Coordination • Geometric Precision • Project Collaboration • Project History

  12. What is AASHTO – TIG?

  13. Mission of TIG – AMG • Dedicated to sharing high-payoff, market-ready technologies among transportation agencies across the U.S. • Promote technological advancements • Sponsor technology transfer efforts • Encourages implementation of those advancements

  14. AASHTO –TIG Team • Partnering with the Contracting Community • Contractors on team • Working with AGC and ARTBA

  15. AASHTO –TIG Partners • Working with Governmental Groups • FWHA on TIG team • TRB • AASHTO committees • Partnering with private sector • Software developers • Hardware vendors

  16. Thank you Ron Gant, P.E., Bentley Systems, Inc.
