You need to replace the civil engineer there (in today's world this is an inspector, I don't know for sure if they are professional engineers or not) for it to be useful, but you still need to have someone not working for the contractor who's incentivized to fake it. The trouble with many of those construction examples is that they're point in time. Installer fucks up how the windows are installed re: flashing and water-proofing, but then puts the siding over it... the error is now completely hidden. You could automated the inspection by AI photo analysis of every single window install on the project, say - but we could already do that for the inspection vs sending someone out, and send the photos to the expert instead, and we don't. Whether that's for lack of incentive to improve, or for ability to go deeper out of distrust for builders? I don't know.
