I could not find it. Do you know if ACI 318-05 has the same requirement?

Just as a side note, ACI 318-08 now requires that the production facility strength tests be less than 12 months old.

Farzen,
From what I have seen, usually it is Xeroxed from something done years before unless the engineer who approves it requires a wet stamp.  It is up to the engineer of record.

In California, could the concrete mix design be signed by just a technician or does it have to be signed by a PE when submitted to the EOR?
