You need to make a lot of holes between the floors. Which is not a problem under normal circumstances. The problems begin due to the fact that the lower floor has a complex layout and there are power cables and communications under the ceiling. In some places, the exit point should not deviate beyond the matchbox. You need a device to position the puncher relative to what is on that side. Will there be ideas?
Reinforced concrete floors. In some places up to a meter.

Answer 1

Drill with level and plumb. To be exact, it is possible with a laser level. Another trick is to hit first with a small drill (6-10), and only then take the crown.
If you absolutely need it, you need special systems and drilling machines on the bed, but they cost like an airplane and it’s easier to hire a third-party office if the work is one-time.

Answer 2
