Coring concrete barrier

Description Text We have a project that did not cast enough concrete cylinders to meet our QA/QC requirements. 

I was asked if it is O.K. to take a 6” core sample out of our single slope barrier for strength testing.

My initial thought was this is O.K. provided that:

The sample did not hit the same rebar.
The core hole would be refilled.
If possible, sample from the non-traffic side.

I wanted to check with you to see if there was something I was forgetting.
