Basement Day 12

Day 12 into our basement project...where did all the time go? Our contractor has started to paint the walls, add casings and baseboards as well as tile the bathroom. We are still pretty pleased with how fast this project has been progressing. At this rate it should be done by early next week if not this weekend. The only thing that I am not so thrilled about is that they don't vacuum/clean up at the end of the day so there's saw dust all over the floor. I am pretty sick of having to vacuum afterwards so I was wondering if I should ask them to do it? I know they will do a complete clean sweep before they put in the hardwood floor, but shall I ask them to at least get rid of the saw dust as they go? Did your contractor clean up every day before they left?
Due to the dust previously mentioned, I have to limit my time down there, and hence the poor-quality quick picture snaps as follows.
