Landscaping and Gardening - Land Shaping
Make your land profile more interesting and functional using heavy equipment.
Ahead of time on your plot map you need to decide the various heights that you want to terraform the land to. Use a self leveling laser and a pole with markers to establish the height of the ground.
You can use paint on the ground to indicate how much ground still needs to be excavated away.
The excavator operator may also have their own laser system (but it is still best to have your own self leveling laser).
Changing buckets on excavator.
Rigging strings is another way to establish levels.
