Concrete Testing Requirements

Applicants must complete two Technical Reports (TR2 and TR3 forms) to identify information about the testing labs, the strength and mix of the concrete being used.

TR2: Concrete Pouring, Sampling and Compression Test Cylinders

File the TR2 to identify the lab that will be performing the concrete sampling and testing. This must be done before permit issuance. A completed TR2 with test results must be submitted before sign-off. The TR2 must be submitted by a licensed Concrete Testing Lab.

TR3: Technical Report: Concrete Design Mix

File the TR3 to identify the concrete mixes to be used on the job site. This must be done before permit issuance. The TR3 must be submitted by a licensed Concrete Testing Lab.

When more than one concrete testing report is required, additional TR2 and TR3 forms must be submitted.

Applicants cannot identify responsibility or certify completion for the concrete inspection and design mix items on the TR1.


New filing fees for the TR2 and TR3 Forms become effective September 20.  The fee is $130 per form per submission.

Applicants must pay a combined fee of $390 (includes fees for both forms and the three required submissions) at permit issuance.

For fee deferred jobs, payment will be required prior to sign-off.
