From October 1, 2009, the Department of Buildings is only accepting the 10/09 version of the TR-1, TR-2 and TR-3 forms.
The new TR-1 has the three changes, outlined below.
1. New item for Alternative Materials
2. Changes to Concrete Design Mix & Concrete Test Cylinders Items
3. Final Inspection Report
1. New item for Alternative Materials
Special inspection responsibilities for “Alternative Materials” is documented on the TR1. A series of OTCR Building Bulletins is issued by Dept of Buildings to define what materials are allowed.
2. Changes to Concrete Design Mix & Concrete Test Cylinders Items
Concrete Design Mix and Concrete Test Cylinders items are moved to the bottom of section 3 of TR-1.
To identify responsibility and certify completion, a TR-3 must completed and submitted prior to permit for Concrete Design Mix.
The TR2 must be submitted to identify responsibility prior to permit and again to certify completion prior to signoff for Concrete Test Cylinders.
3. Final Inspection Report

In these reports, final inspection applicants must attest that the work is compliant with:
Approved Plans
Building Code
