I am also nervous about one doing work in a multi unit building, especially a high rise. How does one know they are not removing a load bearing wall?
Well for one, a modern residential high-rise doesn't have any bearing walls that aren't made out of concrete. The biggest danger to modern high rises are improperly sealed post tension tendons, and trades hitting a PT tendon with a roto-hammer or power driven fastener. And of those, the first occured during erection of the building, and the second can occur to any trade not careful, properly trained of just unlucky. And inspections would neither stop nor catch a hit PT cable.
