Standard Chorus install from an installer who wouldn't know a concrete saw from a GIB saw.
It's like they don't even get they could ping a string line, or even just use some timber as a guide. And then watching them actually handle the saw's is both entertaining and scary at the same time.
Unfortunately it's what happens when you pay peanuts for what is relatively skilled work.
Never mind the pay - try finding at any price the number of skilled workers they need to get through the backlog of installs.
