EOR approval to begin steel erection

[archeng59]

OSHA regulation 1926 subpart R, section 1926.752, requires that the controlling contractor provide a written notification to the steel erector that the foundation concrete has achieved at least 75% of the specified 28-day compressive strength before steel erection begins. Does anyone provide a letter, as the EOR, authorizing and approving the contractor to begin steel erection based on the OSHA requirement?

No, a testing firm should copy the general contractor with concrete cylinder test break results.

I agree. I have a contractor who claims it's the EOR's responsibility to write the letter notifying the steel erector the concrete has attained adequate strength to begin steel erection. First time I've been asked to do that in 15 years of practice.

It's the contractor's resposibility to provide evidence that the supporting structure meets the OSHA req't.
