To add on to the other comments.

You spend money to make warm weather conditions to place those items.

Or 

You accept that anything you install in cold weather is temporary and is going to be torn up and replaced in the summer. I’ve done ACP road paving in winter with the wrong mix (as the asphalt plant was shut down), placing in 0 C weather as we needed to open that bridge that we then replaced in the summer.
