Poor soils can be managed with good foundations. You can put a building on water with the right foundation design. In the case of an office, the safety factors in design are usually pretty high. I’m assuming soil sampling is for modified proctor density. Usually, the criteria for those are fairly arbitrary. Some soils are so sensitive to moisture content that density measurements aren’t very informative. Not blowing up a multi-million dollar construction schedule over a few mm of consolidation is probably a reasonable take.

Knowing it’s wrong and certifying that it’s right entails a lot of professional risk in this industry. I suspect his concerns aren’t too serious or someone else is certifying the work. One other situation I can imagine is that the risk is outside his domain. Example: I saw a company scrape flat clays out of a roadway and use that material as fill for slab-on-grade foundations of duplexes. I wouldn’t expect those to last long, but the developer is also the owner, so he’s only hurt himself. I don’t find the owner to be particularly sympathetic, I only certified the road construction, and the only person to report the poor practice to is the owner himself, who also hired the crew.
