I was thinking about the automation when doing earthwork when I was in the field 20+ years ago.
They tried some things. Like set up a laser to spin shoot across the site and the dozer blade had a reader that would tell the operator to go up or down. That apparently only works if the laser level was setup up correctly they learned.

A quick google search of "laser grading" shows its still a thing attaching to heavy equipment.

Construction Companies are pretty competitive and always looking for an advantage. They have some interesting ideas. (Using radiation to measure soil compaction was my favorite).

- zupzupper 3y agoLaser leveling is very much a thing, I can't speak to grading for construction, but I have several family friends who use it extensively for agricultural fields in California.
- bluGill 3y agoThese days it is done via GPS not laser. With expensive GPS units (RTK is the term to google) you can get to within a couple cm and that is good enough.
