The search you can win begins where the geotech report ends
Every acquisition in North Texas eventually meets expansive clay, and almost nothing published explains what that means for a commercial building rather than a house.
North Texas sits on expansive clay. It shrinks in drought, swells with moisture and moves foundations. Structural engineers working here treat shrink-swell soil as a standing regional condition rather than a surprise, and it shows up in how slabs get designed, how movement gets monitored and what a lender expects to see. Documented engineering, not folklore.
Search for what a geotechnical report covers on a 1980s flex building in Garland and you will mostly find residential foundation repair ads. Meanwhile the buyer under option, the lender's analyst and the tenant rep pricing a build-out all want the same plain answer, and none of them can find it.
Pages worth writing: what a geotechnical report includes and who orders it, how a post-tension slab differs from a conventional slab, what a structural engineer's letter does and does not say, and what belongs on a diligence checklist during the option period.
Two rules keep you safe. Never diagnose a specific property in published content, and send structural questions to a licensed engineer. Write generally, say that you are writing generally, and the page still earns the call.
