It could be a [transit level](https://www.johnsonlevel.com/News/TransitLevelsAllAboutTran) (not the best, it’s an add). I think they’re meauring elevation. Whichever code they are working to probably specifies thickness of layers and grade etc. That is just a guess, I do not work in civil construction.
