IE: LESSON 18 Land Leveling Methods
The formation of grid levels at each point are estimated as given in this table Cuts and Fills Cut and fill are computed by subtracting the original elevation of the point from the formation level at the grid point. At station A1, the cut/fill is 97.296 – 97.30 = (-) 0.004. The results of cut / fill are given in following table.

5 Types of Levelling Instruments used in Surveying
Levelling The instrument is levelled to ensure that the vertical axis of the instrument is properly vertical. It is accomplished by following the steps below: By turning the upper section of the instrument, the level tube may be made parallel to any two of the foot screws.
Methods of Levelling Used in Surveying
Profile levelling is the process of determining the elevations of points at short measured intervals along a fixed line such as the center line of a railway, highway, canal or sewer. The fixed line may be may be a single straight line or it may be composed of a succession of straight lines or of a series of straight lines connected by curves.

What is the meaning of "fill to formation" in road construction?
Formation level is the lowest point on the make-up of the surface finish. The starting point fur the structural material. So a road might have 300mm of 6f2 stone, 100mm capping layer of type 1 MOT stone and then 80mm of base course tarmac and 20mm of wearing course tarmac. So the construction depth is 500mm overall.
