But big tanks do need extra support. This is a relevant thing to post in case someone is thinking about scaling it up.
The Pfizer building in NYC almost collapsed after they tried to build a swimming pool on the roof. This happens semi-regularly when building owners ignore, or don't consult, engineers about rooftop swimming pools. Every owner wants one and doesn't want to be told no.
Pretty sure the pfizer building was vertical expansion without reinforcement.
I dont think they got to the pools. I worked for a company that did a bid for the electrical work. Edit: there was a pool. Didnt have on plans at time
Second edit: looking at wrong plan. There was a pool but it was basically a blank plan with annunderdesigned roof.
Ok, they also added an entire building on top, not just a pool
