Any structural engineers on the board?

[MikeP]

I've had lots of people tell me that it would be safe to put my 190g reef on the main floor of my house. Now it's almost time to move it in and I guess I'm still a bit worried. I don't think I could get the thing into my basement so this is really the only spot for it. The tank will wiegh in at about 3000lbs. The house was built in 2002 and the basement is developed so reinforcing anything would be very difficult. I contacted the builder and after 3 phone calls over 2 weeks time they finally got back to me and said they couldn't help. They archived all the blueprints and now can't find them. They said to contact a structural engineer which I did but that would cost about $700 bucks. Here are some pics, can anyone help out?

This is the room where I want the tank. The outline is right where it will sit, the green tape marks the joists. The wall on the left is an outside wall, the wall behind the tank goes down to the basement (but I still have to try and find out if its a load bearing wall) and the wall on the right only comes out 3 feet.


This is a shot of the ceiling in the spare bedroom right below where the tank would be the walls you see mimic the walls upstairs. For some reason parts of the ceiling are lower (I think there is ducting in there).


This last pic is of the joists in the storage room about 5 feet from the spare bedroom.



Thanks for any help
