I imagine it's very hard work. I imagine the second you step off the truck to the site you're having to hustle hustle hustle. You probably have a foreman that's watching your every move making sure you don't waste any movements. Every man probably has an assigned task for that day and knows exactly what he's gonna do before the truck stops at each site. There's probably some kind of procedure set in place so that each crew member stays out of each other's way. Am I right so far?
