Would this be possible:
Designing a structure of metal or metal alloys with minimal concrete. The structure is basically a platform or single-storey / level floor, about 200 feet X 200 feet square and 15 feet tall, enclosed within a bulletproof / shatterproof glass dome. The entire bubble and the enclosed platform are to be within a kind of elevator which allows the two (bubble and platform) to slide up to an altitude of about 100 - 120 feet ASL (above sea level)
The elevator is to consist of no more than four pylons, also constructed from metal, though they can have concrete at the base, for structural strength. The entire complex is to be built on a beach. Two pylons of the elevator (we'll call them 'legs') are to be within the water, with their bases submerged. The other two legs are on the beach. Access to the glass dome and the platform inside it is granted via an airlock-like room. Once all the people have entered the platform, it will rise using the elevator to its maximum height.
* The entire building will be subjected to noise in excess of 120 dB for twelve hour periods 6 days a week...
* The elevator has to be able to handle lifting the entire dome / platform with about 1,000 people, plus about 1000 kilograms of extra weight twice per day, 6 times a week.
* The structure will be built in the tropics, subjected to heavy monsoon winds and must be constructed in such a way that it CAN withstand hurricane-force winds if neccesary - though the bubble will not be expected to elevate in such conditions...
Now, what I wish to know is, is construction of such a structure possible?
