Best days to order a concrete truck for this type of project would be when the weather is cloudy and the temperature is between 55 and 70.

Agreed as a former concrete producer for 30+ years. On site or “batch mobiles” do not produce a quality product. Any on the larger producers can easily “retard” the concrete to give ample time for transportation to an island. I have developed mixes for WTC that were retarded for over 8 hours with great success.
