AR remote work tools for on-site jobs?

Hey folks! How's everybody doing? Posting this here to see if it sparks any ideas. I'm doing a bit of research on remote work tools used by jobs that are based on on-site presence like construction, home inspection, facility management, cleaning services etc.

Have you seen any great examples of people finding creative applications of AR to work remotely in onsite jobs ? What sucks about translating remote work tools to on-site work?
