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.

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.
