"They have their own crew(s) that are experienced in Wal-Mart's particular layout(s)."

Are they Chinese crews?

I drive a dry-bulk tanker .. cement for batch plants and related product.
I delivered for about a manth last year to a Wal-Mart site that was in the foundation stage.
The overseer of the project was a company from Texas and local work was farmed out by bid.

Not union work as far as I can understand, but a dedicated company used by Wal-Mart. I don't know if they did anything else 'in between' Wal-Marts.
