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.
