请问：如果充气膜结构做在屋顶（4楼平台上），如何对结构进行固定，怎样固定？既然是充气膜是否需要钢结构的支撑？既然是充气膜怎么对结构进行充气和维护（补气）？投影面积1000平方，工期大概需要多久？做好后里面的空调及其他辅助设施怎么布置？另外充气膜的特点是如何的？
如果各位仁兄能给予答复，小弟在这里谢过了！

This is a structure which was built 10 years ago in Holiday Inn Hotel,Beijing.
It is an double layerd air-supported structure and is standing very well till now.
It is worth to have a visit if you really want to make a new one.
