Wade, That is fine. I like to think of it more as a judgment call anyway. If it is 35 and rising at noon, but there is a massive cold front expected after 2:00 with temps in the teens then it does not make sense. The main thing is to make sure the concrete does not freeze. Frozen concrete during the initial cure would not make it though the maintenance period which I don’t believe is in anyone’s best interest. If at anytime there is reason for concern, just give me a call and we can discuss it. Thanks, Clay Barnett, P.E.

I checked the general notes of the plans sheet 18 note 39. This note states that concrete shall not be placed when the temperture is below 40 degrees fahrenheit and falling, but may be placed when the temperture is above 35 degrees and rising. The temperture reading shall be taken in the shade and away from artificial heat. This appears to be taken from NTCOG I have attached there literature with this email. This would be item 303.5.5.2 weather conditions. Please let me know if this is acceptable.
