Floor safety on raft foundation

In my project, the current safety stress of soil improvement is 1.20 kg/cm2, a raft foundation is suggested in the ground improvement report, which does not save with a continuous foundation anyway. However, the raft does not save the floor if I do not make an apartment on the basis. When I gave 1.5 m flats from 3 fronts, it saved it, but the reinforcement increased a lot. What can I do to ensure floor safety outside the apartment?
 
First of all, I suggest you review the slab loads. All roofs (including the roof) have live loads such as 0.5 and 0.65. (wall loads too) I don't know what it means but these loads are too high. Then let him choose the raft reinforcement not only from 14 but also from 16 in the reinforcement options. For raft slab reinforcements, uncheck the reinforcement fixing box at the beginning of the slabs. Clarify the raft slab reinforced concrete calculation axis. (so that the additional reinforcement statuses change) You can review the pursantage values. Select semi-rigid diaphragm in analysis settings. Check Use earthquake loads in the calculation of foundations in Analysis Settings. You can reduce the thickness if the ground stresses are met. (if the reinforcement comes from the minimum pursantage) Again, you can look at the points where the ground stresses spread on the 3D screen and decide where to build a cantilever (ampathment) or how much. Finally, if the soil stresses are too high, this time you can spread the stress distribution by adding a column to the system. In short, I can recommend them.
 
- While determining the floor loads, they want us to increase the live load by 0.15 t/m2 for each wall on the floor. This is the request of the control engineers in the municipality. In addition, they want a load of 0.65 t/m2 on the top floor terraces. - Reinforcement diameters are brought in 8 and 14 due to where I am. They don't even bring 12 gauge iron in my city. It doesn't come with 16 gauge reinforcement, but contractors don't want it either because it's hard to cut and bend. Unfortunately, I am having a hard time as a beginner due to restrictions. - I made the changes in the analysis settings. I've never solved a semi-rigid system, I guess I'll have to do some research.

There is no such thing. What is meant by "every wall". This is wrong. Then it should be said that every brick we put in. Even in the parking lots, the live load is 500 kg, which you probably build here. The load of the slabs bearing the wall is increased by 150 kg. Otherwise, if it is 150 kg for each wall, it will return to the construction materialist. Remind the friend in the municipality (?!) who said this. In the attached link, I also put the picture of the article in a pdf file published on imo's page. Take it easy
