It also looks as though the metal posts are sitting on the 2x4 bottom plate which is on top of the drycore. Those posts need to go to the concrete floor and be directly fastened to the beam. The old post locations would have had a peir built in under the concrete floor to distribute the weight above according to the house engineering. Moving those posts creates loads in the wrong areas and since you installed the drycore....you will not be able to see any cracks which start to form.
I am not trying to alarm you, but this is just the types of things I can see causing issues down the road. Foundation beams and bearing walls are the starting point of your home. When we start to modify them without understanding the engineering which was involved in the beginning, you end up with problems . That is why we have Building inspectors to help out when we get ideas of updating our houses. Having been a builder for 25 years I understand not wanting one coming around, and having to pay the man. But when you don't get them involved, you can end up with serious problems.
Enginerring of bearing points is a big issue with me. These points are not arbitrary or just there to hold up your house for everyday living.
These areas of the home only need one weak link in a major storm or catastophy once in your life. Then they fail, and you are stuck under the house when you needed it to hold together. We have all seen that one home in the tornado still standing....we just cannot figure out why. Well I know why, it is because it was built to withstand that issue, was not modified at all. and had a good keeper upper to stay healthy.
Just like everything else in life, only the strong survive.
Getting off my soapbox now.
Hope that helps, if not I'm sure I will hear it......
