Model Integrity Checklist

I wrote a post a couple years ago on Model Integrity and developed a checklist for checking your BIM. Model integrity is becoming more crucial as projects are becoming more complex and model data integrity is a crucial aspect of deliverable quality.

BIM Integrity is a topic I will be writing more on soon, so keep posted! 

I have recently revised this list so I'm re-posting this topic.
 This checklist is part of a protocol to maintain model integrity.

This is a simple checklist where the auditor can verify model content and process making sure that the Building Model is constructed in accordance with your standards and project requirements. 

Verifying Model Integrity periodically throughout the project reduces the risk of incorrect modeling causing misinformation and/or additional unnecessary work.

Validation of the model provides a guide to address any potential model issues, the intention being that the recipients of the model know the file is fit for use and will not require additional work to fit within the project framework. 

This checklist allows for issues to be tracked and resolved in a timely manner as they arise.

An Audit should be carried out periodically throughout a project to verify model content integrity by the Project Model Manager as well as by the BIM Manager.

A copy of this audit is to be kept on file as well as sent to the BIM Manager upon completion.

It's a basic two-page checklist. 
Here's a sample of some of the items:

• Is the Project Information Data completed
• Has True North and Project North been established and used correctly
• Is the Standard Project Browser being used properly
• Complete spell check (you will be surprised)
• Is all text in upper case
• Delete unnecessary Reference Planes and 3D views
• Purge the "coordination" model
• Revisions, Site Instructions, C/O’s been completed according to the Standards
• Are Annotation styles consistent with  Standards
• Are Dimension styles consistent with Standards
• Are Drafting Lines being used where the Linework Tool would be better (and Visa Versa)
• Are Line styles consistent with Standards
• Is the Level of Detail in the model appropriate for the scope of work
• Are objects on the Correct Workset
• Is content all approved by Model Manager

Some of these are pretty basic and common sense but it's always good to be able to check it off and know that it's been done. I'm sure there is much more, please feel free to send me your comments and I'll post them to this blog for everyone to view.

Integrity in Modeling is key to quality, risk mitigation, and general good practice!
