So. I have what I'm sure is not a unique problem, but sure is an interesting one.

The people who built my house built the foundation wrong. Instead of digging a hole, then digging a deeper trench for a foundation, which insures the foundation is on compacted soil, they made a mold around the edge of the hole. Then put some sand on top.

As you can imagine, 60 years of settling has resulted in my foundation kind of sitting on tiny plateaus of compressed sand, and those plateaus are slowly eroding away. Especially in this one spot where there was water seeping in because they also did the grade wrong.

So anyhow, my understanding is that the best solution is to add a bunch of fill dirt into the 5ft "luxury crawlspace," compressor, and repeat until the dirt is at least level with the foundation footer. To the tune of approximately 60 cubic yards.

As you can imagine, this is an awful lot of dirt. And the only entrance to my crawlspace is a 10sqft hole at the back of the house, far from where dirt could be delivered.

How the hell am I supposed to do this? I feel like the most cost-effective way would be to have the exterior wall and floor of one bedroom ripped off so that the dirt can be pushed/poured directly in, and then an army of assistants spreads out the mess.

I'm sure I could ask a contractor (and will given scope of work), but I'm trying to get a rough feel for the work required so I know if I'm being completely ripped off.
