Why would you nail the base wood floor down to concrete, rather than adhesive bond it??? Especially with only 3/4" cover over rebar? How many rebars do you hit nailing it down with 2-1/2" powder driven nails or standard concrete nails? Definitely would be a lot of pounding with 2 layers nailed down plywood and then nailed down hardwoods.

Careful, the answer is tricky.... It depends greatly on how many upper rebars you ass_u-me are in the slab.....

Columns E2/2.1, which ever it is), E4 are just beyond this I'm assuming.

Yeah. You can positively identify that location from the double column at the very start of the video, on the left of the opening frames. That's A2 & B2. The drilling firefighters are stood between D2 and D5, drilling pretty much directly towards E4. E2 is slightly to their left, hidden in the collapse.

Any Star Trek fans in this thread?

Why do you ask? (something about being beamed up or down?)
