This is great, thanks Ivan. Yes, the system will also need to act as an MNS. Thanks again, and looking forward to any other suggestions anyone may have.
ALso be sure that the installer is aware that since it is part of a MNS-it falls under NFPA72.  Which is a WHOLE different "set of rules"-including what kind of gear can be used-what type of wire-survivability of the system-inspections-performance requirements and so forth.

It is NOT your normal "ceiling speaker" install.

Somebody could be a lot of financial trouble if they do not address that on the front end.

The refurbishment is being phased on a floor-by-floor basis (i.e. the rest of the building will be live when the individual floor is being done). There is no overlap with the existing system, which will be phased out when the relevant floor is gutted, and whose central equipment is located in a different place.

Be very clear up front about whose responsibility it is to keep the rest of the old system running while the GC goes in with sledge hammers and wire cutters. Just because the floors are separate zones doesn't mean they won't hit something passing through and you want to settle ahead of time who will come fix that up and whether it is included in the construction bid or not. (you can decide if you want to take the risk or if you want them to pad their price enough to take on that risk)
Also, while this is in progress will the old and new systems be linked? which is the master? I would step through the timeline of the project and think about what the system will look like and how it will operate at each stage.

Thanks Jason. Hadn't thought about this and I will bring it up with the team before deciding who will take this on. The old system will not be linked to the new and will be phased out floor by floor, so it will mainly be about managing the pass-through risk (which is very likely in this old building). Thanks again

Selection done, now to arrange for a listening test. Thinking of playing some pink noise and programme material for both the ceiling speakers and the auditorium speakers (the latter in the proposed space prior to renovation). Any other suggestions? I will look for rattles, build quality, etc., although the products are name brand and should not have any issues.
