7. Presentation Outline Project Introduction Analyses Overview Analysis I – Building Information Modeling Analysis II – PV Panel System Analysis III – Secant Pile Wall Alternative Conclusion and Acknowledgments Questions Analysis I - BIM Interview Results Asking for use of BIM for MEP coordination, but not for specific deliverables. Asking for “BIM Implementation Plan” from contractor for use during construction phase. MEP as built drawings; warranty, service, and other O&M data built into master file.

8. Presentation Outline Project Introduction Analyses Overview Analysis I – Building Information Modeling Analysis II – PV Panel System Analysis III – Secant Pile Wall Alternative Conclusion and Acknowledgments Questions Analysis I - BIM Results Continued… Government owners (USACE, NIH, GSA) asking for more robust deliverables. Master file with specific levels of detail, linking of files in specific ways, specific inherent data within the model. Majority of owners not asking for any deliverables, but small group of very proactive owners asking for robust deliverables. Owner knowledge is expected to increase, deliverables more complex.
