    The problem here is that the wall was not constructed properly to begin with. Any wall taller than four feet should have Geo-grid, if it is going to have any amount of pressure on it from dirt, traffic,etc, there should have been an area of slag behind the wall and a drain to remove the excess water that is now coming through it. Refer to a professional in this area of knowledge.

    The 4' rule is for a perfect world. Some walls under 4' need grid.

    Always remember - if it was a perfect world...a wall would not be needed. :)

    The key work in that cross section is Typical!!! Just from looking at the pictures above it looks to have a parking lot light above the wall. So I am going to assume that there is a parking lot to the edge of the wall, and must have some sort of run off collection system. AKA: not a typical wall section!

    I understand your point.....I was just trying to show the OP how a wall like that is built.

    I must be exhausted. I just keep re-reading this line and laughing out loud by myself. I Dunno why, but its hilarious (and very true).

    My thought would be the base is failing causing that movement. Bad compaction, poor drainage (or none).....You could keep your good relationship with him by explaining the severity of the problem and look to professionals for guidance.....engineer or hardscaper with a lot of wall experience

    How tall & long is the wall? Looks pretty f'n huge from the pic.

    How did you arrive at the above prices? I would price it at easily 5x what you said.

    Whats at the top of the wall? Asphalt? If so, there will be a big patch that will be needed once you finish backfill.

    What equipment do you plan on using for this? Personally I would use a big skid steer or small loader and a 5-6t excavator. You will have skids and skids and skids of block to stack and store as you disassemble it.

    Maybe there is an engineer that designed it the first time that can be called out to fix. With an engineering designing and doing special inspections they should be liable for the structure- correct?

    I make sure to follow prints to the "t" even if I don't agree with them 100% the moment I deviate it becomes my problem.

    We saw cut duct chases into a cast in place concrete hotel. I noticed some cracking close to one of the locations we were to cut.... you can be sure I photographed and sent to the arch/engineer on the job and got approval prior to cutting.
