I have a jump footer in a 16 x 8 crawlspace underneath a breezeway that connects my house to the garage. I’ve been digging in there with the intention of repointing and to install a perimeter French drain. I hired a contractor last year who did a terrible job supporting the floor joists with a single post and triple 2×12 beams that are sitting directly into the block wall on either side and were hydraulic cemented into the wall. Additionally the 2 pieces that meet over the portland filled lally column have a 3/4″ angle and are not straight at all. The footer they poured is 2x2x 9″ deep. The floor joists they put up dont even sit on a proper sill plate (the garage side.) The far wall in the pictures is the garage wall and is 4 ft high. The 2 shorter 8 ft walls are the front of the house and an internal retaining wall with an internal concrete staircase on the other side of it. Both of the short walls have steps in the footer starting about 3 blocks in off the basement wall. So i have the 16 ft basement wall entry which is 8 feet to the footer, the 2 short side walls are both 7 blocks high at 4 ft 8″, and the garage wall is 16 ft x 4 ft. The gap in the cross footers is roughly 4 feet. There is an original footer drain tile on the outside of the basement wall in the crawlspace that was cut and a sump pit put in before i bought the house. It sees a lot of water and there is significant settling of dirt coming into the room from under the garage. The garage wall has major signs of stair cracks and is tipped into the crawlspace 3/4″. I even paid for an expensive engineer who approved the work and didn’t know any better at the time.

I am thinking I need to reach out to the contractor, engineer and the inspector to see what can be done to fix all the issues with the structural framing. I’m also hoping for some advice on how I can address the jump footer and improve the drainage in the room so that I can vapor barrier it. the column in the middle of the room is preventing me from excavating a straight line across the middle of the room so I can build a cmu wall higher than the garage wall footer. I’m thinking it should be removed in favor of 2 sets of cross girders that are off center and NOT placed directly in to the walls but instead on individual footers and column supports. If i build a wall in the middle of the room, how can i run a continuous perimeter drain tile into the sump pit located by the footer of the basement wall?

I read the below post and am starting to get some ideas but would appreciate advice unique to my jump footer in my crawlspace between the garage wall and basement.
