Building Information Modeling Standards (BIM)

The intent of these BIM standards is to provide for the consistent development and management of Building Information Models on State building projects.  These BIM standards apply to Designers and their Consultants, and/or to Contractors and their Subcontractors, selected by the State Procurement Agencies (SPA’s) for projects designated to use BIM.  Additionally, these BIM standards may be voluntarily used by Designers, and/or may be voluntarily used by Contractors, working on State projects who choose on their own to use BIM and agree to do so according to the State’s standards.

TN OSA BIMs Version 2.0 - July 2020 (Current Version)*

* TN OSA BIMs Version 1.1 – July 29, 2015 has been replaced with TN OSA BIMs Version 2.0 – July 1, 2020. TN OSA BIMs Version 1.1 or Version 2.0 may be used on BIM projects that commenced prior to July 1, 2020.  All BIM projects commencing after June 30, 2020 must use TN OSA BIMs Version 2.0 - July 2020.
