I know Roman Empire didn’t suddenly disappear it was more gradual.
Romans used advanced techniques to build their fantastic buildings.
I guess to expand on my question I've seen examples of advanced column cutting and boring granite that even with modern tools are hard to do.
Wider than that though you’d need surveyors and other experts to do this.
Did the loss of skills start inline with the empires decline and are there historical texts outlining this?
E.g., in the modern era, it’s common to say they don’t ‘build it like that anymore’ or ‘we just don’t have the skills nowadays’.
Did the Romans start recognising falling standards? I.e. call out say where roads were in disrepair, etc.?
