P.M., Boilermaker. Good weather.

Construction weather was previously discussed and boilermaker provided an answer.

If you are dealing with 90F days it might actually be somewhat easier on the men and equipment to conduct operations in spring or fall weather. A Nebraska winter should not stop construction. (Maybe a Blizzard keeps you from driving to the job site?)

In terms of daylight yes, we have passed summer peak.

I wondered whether there was any benefit to doing ground freezing operations in colder weather. (Less energy required for above ground heat exchange for the brine?)I found an article at this link, which does NOT answer that question. I am however, posting this "3 min read" for the sake of general interest.

A link for anyone is interested reading about construction problems encountered in cold weather. The first paragraphs outline some of the problems encountered in high latitude or sub arctic construction.

Elk Creek sits at 40.22 degrees north latitude and 1135 Feet elevation, and anticipates about a 40" freeze line during a really hard winter, so extreme sub arctic cold operations construction procedures would not apply.
