· Bench-marks (BM) They're fixed factors or marks of recognized RL identified with reference for the datum line. These are vital marks. They serve as reference points for locating the RL of recent points or for conducting leveling functions in tasks involving streets, railways, etcetera.

It helps surveyors and engineers to level, design, plan, and assemble a making by building the land suited to building

· Lessened stage (RL) The vertical distance of a degree earlier mentioned or under the datum line is called the reduced stage (RL) of that point. The RL of a degree could possibly be good or negative according as the point is earlier mentioned or beneath the datum.
