Benchmark: A point in a level loop that is stored in the current job.
Benchmark points are usually permanent marks on the ground that
can be reoccupied at a later date. Benchmarks are part of the level
loop since they are used as the backsight for the next setup, with the
exception of the closing benchmark.
Leveling Side Shots: An intermediate shot from any setup in the
level loop. Side shot points are stored in the job file, but are not part
of the loop (they are not used as the backsight for any setup).
Leveling Stake Points: An intermediate shot from any setup in the
level loop where the elevation is compared to a design point to provide
cut/fill values.
Turning Points vs. Sideshot/Stakeout Points: A level turn is the
BS – FS observation that calculates the elevation of the next point in
the loop. A level turn always advances the level to the next setup in
the loop. A side shot or stake out is a FS observation to calculate an
elevation of a point not in the loop. A side shot or stake out
observation does not advance the level to the next setup in the loop.
