I have a structural question. I have a two tier raceway a client wants. Each raceway has 46.5 m3 of salt water. ( aprox 16' x 40' x 32.5" ) tier one is 1.9m above grade tier two is 3.1m above grade Each raceway is 716 ft2 -- 65kg/ft2 ( 143.3 lbs/ft2 ) total weight to be supported 93 metric tonnes of water with a total of 22 raceway stacked pairs. Looking for a BALLPARK feasibility. Structually is this going to possible ( within reason ) or simply too expensive? Underneath the raceways needs to be relatively open as well for access.
An education isn't how much you have committed to memory, or even how much you know. It's being able to differentiate between what you know and what you don't.
