I first heard about it from a twitter account that follows emergency services scanners. With emergency services notified, Department of Labour would have been automatically.

I don’t see where there is any sign of rushing. Demolition would be challenging work with unknowns and a changing structure. It appears a void must have partially caved in. This looks a little more extreme than it is due to the arm position. Had the tracks been 90 degrees to where they are, there would have been no problem as excavators can handle steep grades.
