3 topics across all disciplines.
Soil investigation and compaction — the tests behind the report
What a Proctor test actually establishes and why field density is meaningless without it, the difference between Standard and Modified, why optimum moisture content is a target rather than a maximum, what sabkha does to buried concrete, and how a compaction result gets flattered without anyone lying.
Foundations — how the soil report decides what you build
Safe bearing capacity, shallow versus deep foundations, why vibrating equipment needs a different design, and what the civil engineer needs from the other disciplines.
Piling and deep foundations — necking, founding stratum and integrity
How a pile carries load through end bearing and shaft friction, what necking is and why a bored pile can develop it without anyone seeing, why the founding stratum must be proved rather than assumed from depth, what pile trimming is for, and how equipment bases get grouted.
