Answer 1

In my experience, they mostly catch trash blowing across the construction site. A working site generates tons of random trash, from scrap pieces to cardboard boxes and plastic wrap. Having a low barrier around the site keeps it from blowing into nearby properties. Each morning the grunts can walk the perimeter and clean up whatever gets stuck in there.
