Hello Mr. kltinsaat. What I saw in your project: 1- DO NOT MAKE A GRADUAL FOUNDATION. I wouldn't. YOUR GROUND SAFETY MAY BE A PROBLEM LIKE LOW. 2- If there is a level difference on your land, make sure that the lowest foundation does not remain on the surface 3- Your balcony loads should be .35 4- Close the balcony ribs. 5- If one side of the balcony ribs is not open, the filling material will fall. 6- Provide continuity in the ribs 7- you do not have a load of stairs 8- Won't you put a mezzanine beam on the stairs 9- lift KB103 in the basement 10- let your foundation beams and rib-bearing beams center the columns 11- you fixed your basement curtains in the calculation, it gives an error. open it up. 12- basically, you have increased your ground safety by 50%, I think, do not increase it by 25% 13- increase your foundation beams that do not save ground safety 14- errors increase when the superstructure is solved interactively. Fix these errors. 15- After that, you have to pour the foundation step by step. Lay stabilizer under the foundations of the upper level (I AXI TOP), compact it in accordance with the procedure and pour the upper level foundations. 16- The columns in the middle S6-7-9-13 are too high. concrete may decompose while pouring concrete. You can pour them in two stages. 17- You'd better increase the I axis foundation width by 20 cm. 18- Solve your last recommendation structure as SEMI-RIGGED DIAPHRAGM. Take it easy, have a good work Unver ÖZCAN
