If the thickness of the concrete is insufficient the weight will cause the concrete to give way or crack and sink. I helped a friend do the same thing only not as drastic as yours . His span was 26' and the I beams he used were side by side and the same web and thickness. He did have some settling upstairs , doors sticking and drywall cracking. Maybe if you installed a bigger plate under the I beams to spread out the load.

The removal of the studs and the installation was done by a licensed and bonded foundation company. All they do is foundation repair and modifications like mine. They do not do drywall framing or anything else only foundations. The thickness of the foundation was tested to make sure it was thick enough, when the drill made it to 5" he quit drilling and said there was more than enough to support the weight on the dual posts. The span that is between the posts is only 20' and with a 5" plus thickness in the foundation I do not think I will have issues. I did not want to ruin the drywall and doorways so I payed the pros to do it!!!!
