I am architecture student and as one of my academic project I am designing a highrise mass housing project in india and stuck for the construction of podium... I am trying to put the 2 level podium after stilt and another on the 8th floor. I don't know how can I work with that.. I don't want the columns to go so long.. and if cantilever what I will have to use and how much span.. it's a huge site 100 m x 200 m . Is there any alternate option?
