Does anyone know where I can find out how much weight a floor will hold.

I am planning a new tank. i am on the third floor of an appt. building.
I have a 150 with 90 gal sump, they are offset so the weight is distributed. My new tank will have the sump underneath, and the main tank will have a wider/ shorter base.

Any suggestions would be appreciated

Thanx in advance
