Ok, I get the premise and I can see you have put a lot of thought into this, which is good - it means its going to work out well.
The premise for the building being a cyber research clinic that requires trillion dollar investments? Not so much. Cyber research is a core item for all of the big 10, this is where we have gotten things like Cyber Zombies, Delta-ware, and Jar-heads from.
This is going back a ways to 3e but in the SOTA 2064 (or was it Year of the Comet??) they listed the cost of lifting a single Kilogram of material into Orbit at 10,000 nuyen for the Corps that owned their own launching facilities (at that time, there was 3 Megas that had their own facilities). The cost of just lifting the crew of 61 would be amazingly expensive! Such a station would have to be a multi-task project, probably in the high tech construction supply chain. ("they make the bio-crystals used in computer storage technology in space because the 0G environment leads to better dispersion of the cells in the quartz matrix.") Or several such items.
There are several underwater habitats already that such a facility could be found in however. 2 are owned by Maerak (a AA Corp) and 1 by Shiwase (I think). But again these are mostly aquacrop farms, and marine resource extraction sites... But they could put in a cyber research lab if they felt the need.
However, I can see this facility more in land. And actually fairly close to a major city. Glo City in Seattle would be a good spot. huge background count to keep astral snoops at bay, toxic environment to keep away most people, isolated enough that anti-intrusion measures can be used with impunity.
Toxic critters, awakened nasties, ghouls, toxins, diseases, radiation. No services, no shops, no running water, roads not maintained in 40 years for kilometers in any direction. Empty condenmed buildings crumbling all around making good hiding spots for devil rats, ghouls, or even shadow spirits, the few people to be found are crazy... and then you get to the gate....
