Below are images from site survey of a location this is going to be complex to install.
In order to make a suitable install surface, the general contractor is going to have to:
1: Drill cement anchor bolts into the TRUE ceiling (about 10 feet above the false ceiling tiles).
2: Attach around 9.5 feet of threaded rod.
3: A 2x8 in place to span the 12 foot span of the install.
