What would you suggest as a method of reducing reinforcement?

Slm I'm solving a project of 900 m2 construction , hollow floor slab, but despite all my attempts, the reinforcement is too much. What can I do? I will be glad if you help

You only said the construction area, you didn't even say the tonnage of the iron. That way no one can help Share your project if it's not private. Classically - check the loads, correct if there is excess load - if you have given the wall load to the beams, also cancel one if you have drawn on the wall - determine the R coefficient according to the curtain ratio - if there is an unnecessary large column and it works with minimum reinforcement, reduce the column
