How land is made flat at scale

For building something like a big building or a parking garage, there is a need for a large flat surface of concrete. Wondering how they make the dirt and the concrete flat. It's hard to make a tiny flat surface at the beach in sand let along thousands of square feet. Wondering what sorts of machines tools or techniques are used at a high level.

Tear it up:
Smooth it out:
John Deere makes similar equipment, too. See here and here
The concrete is either poured in sections or pre-cast and delivered on-site. So the traditional techniques still work at scale.
What about the leveling part, making sure it is level. Maybe just a string at two points, and then the handheld leveler device at each end. But that doesn't account for bumps or small arcs in between. Wondering if it is just done by eyeing it.

For big constructions, there is a survey plan and a few bench marks marked and cemented by the surveyor. Then at the time of excavation there are auto rotating laser levels that cast a level moving beam which is easy to see and follow. there are reflecting mirrors and elevation readers.
Excavation is done in stages, from rough to fine contours using different heavy machinery depending on the type and configuration of the site. Many jobs call for presence of soils engineer at intervals to test the soils and determine their properties and if they match the projects soils report.
Concrete slabs can be leveled with vibrating, moving, or, rotating screeds or operator driven motorized finishers or manually. There are plastic stakes that mark the finish level and the have fittings for long aluminum levels.
Structural drawing s usually call for 1/8" to 1/16" tolerance in slabs level.
