5. According to a survey by the joint BIM committee of the American Institute of Architects and Associated General Contractors of America, 74% of the 1,266 respondents said they're using 3-D digital modeling at some level. The Merry Road to BIM By Jeff Yoders, August 11, 2006,Building Design and Construction • Trends in BIM • Frank Gehry His work includes the Experience Music Project (Seattle), the Guggenheim Museum Bilbao (Spain), and the Walt Disney Concert Hall (Los Angeles); Constructed by Mortenson Construction. • GSA: US General Services of Administration The GSA has even taken the extreme step of mandating the use of IFC-based BIM and believes that BIM adoption should not be driven by cost savings alone, but for its many other benefits such as the ability to explore different engineering systems, perform energy analysis for LEED certification, derive specifications automatically, and eventually eliminate the use of paper and paper-based processes Review of Literature:

7. Case Study • SHSU Academic Building 5 @ Huntsville, Texas: • Designed by WHR Architects • Constructed by SpawGlass Construction • Project Start Date: 15 May 2007 • Project End Date: 26 September 2008 • Project Duration: 16 Months The project is a 4 story high building with a basement and penthouse level Research Case:

8. SpawGlass Construction • Expected Benefits from BIM • Integrate Time schedule: 4D • Detect Design Conflicts • Update the 4D model as the project progresses • A need for dynamically integrated 4D model • Sub-Contractor Co-ordination. • Parts of BIM not tested • Quantity take-offs • Resource allocation: Man-hours, methods and materials • Cost allocation across project duration • Facility Management Case Study: SHSU Academic Building 5

9. Constructor 2007 Modeling Interface Scheduling and Generating reports Estimating Interface Cost reports Plays a 5D real time- space file. Case Study: SHSU Academic Building 5

10. Model Transfer • Expected Transfer using IFC extension file • Convert Revit file to IFC file • Open IFC file in Constructor 2007 • Add schedule in constructor • Create the sequencing file in Presenter 2007 • Issues encountered • IFC Conversion is a time-consuming process • Unexpected scaling of elements in Constructor Case Study: SHSU Academic Building 5

11. Challenges • Creation of second BIM model with necessary details to integrate all scheduling activities. Case Study: SHSU Academic Building 5

12. Challenges • Creation of second BIM model with necessary details to integrate all scheduling activities. Case Study: SHSU Academic Building 5

13. Challenges • Creation of second BIM model with necessary details to integrate all scheduling activities. Case Study: SHSU Academic Building 5

14. Challenges • Scheduling to reflect updated schedule • Linear Scheduling using Construction Simulation File No option for predecessor / successors relationship logic Case Study: SHSU Academic Building 5

15. Challenges • Scheduling to reflect updated schedule • Dynamic Schedule using Recipe Menu • STEPS INVOLVED • Start project in Estimator: Establish Project Database • Assign Recipes to Building elements in Constructor • Define the Work Breakdown Structure • Assign Construction Zones • Add Task Durations in preferred scheduling software • Export the 4D model to Presenter Result: A dynamic scheduling file made from scratch using Constructor 2007 Disadvantage: No scope to dynamically connect an already existing schedule using Constructor Case Study: SHSU Academic Building 5

16. Navisworks – (Currently under tests) • Scheduling to reflect updated schedule • Dynamic Schedule using Recipe Menu • STEPS INVOLVED • Convert Constructor/Revit file to Navisworks file format • Link an already existing schedule to Navisworks • Assign building elements to task components • Play real time-space interactive animation file Result: A dynamic scheduling file made from existing schedule. Contractor need not change traditional ways of conducting business Disadvantage: Navisworks does not let the user draw additional components. One needs to use Revit+Navisworks OR Constructor+Navisworks. Case Study: SHSU Academic Building 5

17. BIM issues identified so far. Case Study: SHSU Academic Building 5

18. MISSING END BEARING FOR BEAM.

19. BEAM LOCATION INCORRECT

20. Clarify detail A6 on A 301. Is there a concrete section behind the MS beam ? DRAWING INFORMATION CONFLICTS

21. East canopy Additional Details are required to construct the glass canopy DIMENSIONS MISSING

22. Work to be done Phase 1: Modeling of Architectural/ Structural Elements Phase 2: Test Scheduling Connectivity using Constructor/ Revit Phase 3: Test Scheduling Connectivity using Navisworks Phase 4: Modeling and scheduling of MEP elements Phase 5: FinalReports Case Study: SHSU Academic Building 5
