Virtual Design and Construction
- 1. Virtual Design and Construction
- 2. Virtual Design & Construction is …The computer simulation of the architectural definition and assembly of a building project. Virtual Design andConstructionBuild Prototype(s) and Analyze Best OptionBuild and ANALYZE a virtual model TWO…THREE times – Reduce project RISKPredict possible Logistical CONFLICTSBUILD Cheaper, Faster, Smarter
- 3. WhyVirtual Design and Construction
- 4. Industry Productivity at a Glance Frequent Project Cost Overruns
- 5. Frequent Project Schedule Overruns
- 6. Prevalent Change Orders
- 7. Rising Legal Disputes
- 8. Lack of transparency
- 9. Inefficient Current Processes
- 10. Lack of Interoperability Additional cost of interoperability in the construction industry 2002 (in $millions)Source: NationalInstitute for Standards and Technology (Gallaher et. Al 2004)
- 11. Purpose of Virtual Design and Construction??10/28/2009PROTECT INVESTMENTS, BANKS, and DEVELOPMENT/GC companies
- 12. Make INFORMED project investment decisions on-time.
- 13. REDUCE RISK
- 14. Control cash flow and find optimum for Development Project
- 15. Transparency with Banking Institutions
- 16. Produce EFFECTIVE and EFFICIENT construction projects
- 17. Minimize waste, Extra Costs, and Legal Problems

- 27. Accepting only candidates with BIM experienceVDC AdvantagePRICE – eliminate unnecessary costs and find the best option TO BUILDSCHEDULE – optimize activities and reduce project construction timeCONSTRUCTABILITY ANALYSIS – find and fix errors before they become expensiveTEAM – align with expert VDC EngineersTECHNIQUE – most advanced technology and process10/28/2009
- 28. VDC/BIM Case Study CONCEPTUAL ANALYSIS
- 29. Conceptual VDC Analysis Process10/28/2009Time from client/owner feedback to implementation and analysis is significantly less than traditional methodsRepeat for each new conceptual version in order to arrive at optimum.
