This practical is performed to teach students how to determine the relative heights of different points using a leveling instrument. Students learn to set up the level, carry out temporary adjustments, and take Back Sight, Intermediate Sight, and Fore Sight readings. By using these readings, they calculate Reduced Levels (R.L.) of various points through the Height of Instrument (H.I.) method or Rise and Fall method. The activity helps students understand the principles of leveling, develop accur
