This type of thing is till done. One time, I was on a job a few dozen miles from the beach.

We leveled the lot, dug up a few feet or so. Placed markers to check later for settling, then brought in fill dirt to create an "overburden" mound.

I was told that some compaction will occur the first month from the weight, and then a year later they would measure how much more it has settled.

If the was determined to be stable, remove dirt mound, install building.
