Volume of a sphere enclosure with radius 15.5 meters and a hollow center sphere 15 meter radius is around 1100 cubic meters. Specific weight of concrete is 2.4 g/cm^3. This monstrosity will weight between 2500 and 3000 tons. It will gain buoyancy when filled with air but the need for maintenance might be due to not being able to move water into and out of the sphere in which case you can add 10^5 more tons to what you need to lift out of the water (in which case I think making repairs at depth might look favorable).
It's probably doable. But it's going to cost a pretty penny.

Unless it was possible to do everything with a remotely controlled diving robot, that is :)
