There are a lot of rules. I'm sure the sparkies will chime in with the bad news. What type of building is it? At eight storeys, romex would probably be disallowed in any case. Whether conduit or MC cable is ran, it will need to be fastened at a regular pattern along the chase, I don't think you would be allowed to drop and drape the wire down the hole. Any penetration thru the chase would likely need fire caulking.

Some of the fire caulking requirements may not be applicable to a very old building, and some aspects of the building may allow some degree of "grand fathering". But given that this is a new circuit(s), you could expect that new building, electrical and fire codes will be involved.

You need tpo consult s pro who is savy about commercial and/or multi-family construction. Be aware that many residential romex rope-pullers may give you a good price, but their knowlege may be lacking. As a commercial and industrial superintendent of many years experience, I have dealt with more than one fresh faced residential electrician who the owner threw on a commercial job because the owner could get him very cheaply. I literally knew more about commercial wiring than he did.

You could do individual wire runs but it would probably be easier to run conduit supported at the right intervals for the particular size you plan to use. You may also be required to use some sort of strain relief on the wires to avoid them falling into the pipe. The low voltage and 220v runs can't be run in the same conduit. This was based on the code for my area. Sure an nec expert will chime in soon if anything's different.

If it's not longer than 100', no worries. If it is longer than 100 you'll need some sort of strain relief depending on your wiring method.

Wouldn't 330.30(D) preclude that?

I'm just going by 300.19.
Not sure what the wiring method would be, the OP isn't making that clear.

Some inspectors (if it's getting inspected) may consider the metal clad a raceway, especially if they just went to a seminar

The OP probably isn't sure himself. Eight storey building isn't going to be a legal DIY project in the US, unless the OP happens to own a eight storey SFR
