Re: the enhanced barriers at BC Place. I seem to remember there was a guy (I think he was drunk) that fell over the barrier during the Olympics. He was seriously hurt but survived. Maybe there was a lawsuit.
Re: the concrete structure on the north plaza at the library. It was a crane base. They did major renovations to the roof. I look forward to going up there when it's all done.
Re: the open balcony at PARQ. I wonder if it's a designated smoking area. I think a lot of their clientele would be smokers and they WILL go to have a puff somewhere so you may as well let them go to one place rather than have them in the stairwells and clustered around the entrances and exits.
