Upgrading Tank, Weight Question

[onein8billion]

Hey all,

I currently have a 45g tank, but I'm looking to upgrade to a 90g. Since I live on the second floor of Manhattan apartment building (built 1970s), I asked my co-op board if this was feasible and gave them a weight estimate of 1100 pounds. They told me I would have to hire an engineer to review the plan and get his opinion.

I have no problem doing this, but the guy they suggested charges $200/hr and said it would take an hour minimum. I really don't feel like spending $200+ that could otherwise be spent on equipment or livestock. Does anyone know any engineers who would do it for less, or any other solution?

Thanks for your help.

My old apartment building was built in 1950's and I had a 90 gallon w/o any issues.

Yeah, I don't think there would be a problem either... It's just that my board won't let me have it without the engineer's approval.

Has anyone gone through this process before? From what I understand, they don't even need to see the apartment, just the plans.

also you have to put in the count 2-3 people standing in front of tank (400-600lbs)

If you were to fill the tank entirely with salt water it would weigh 792 lbs, Not including the weight of the tank and stand. Saltwater weighs 8.8lbs per Gallon at a 1.025 salinity. I had a 125 in the upstairs of my parent house when I was in H.S. It held up but I also added more support from the basement up.
