This Blog is dedicated to all things to do with Building Information Modeling.
I'll be blogging about challenges that I come across as BIM Manager as well as points of interest that are related to BIM. Blogs on tips and technical "How-too's" to help you out with creating your BIM models correctly.

Model integrity is becoming more crucial as projects are becoming more complex and model data integrity is a crucial aspect of deliverable quality.
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. This checklist is part of a protocol to maintain model integrity.
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.
A Model 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 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.
Integrity in Modeling is key to quality, risk mitigation, and general good practice!
