For establishing vertical control points in a new construction site (building), the following readings
were taken starting from BM 1071 toward point A and closed at the same BM:
1.045, 0.912, 1.233, -2.409, 0.885, 1.324,1.544, 0.944, 1.456,1.904, 1.715. The total travelled
distance was 1050m. (Note: A, B, C, and D, are change points), Elevation of A is 83.141m
1. Calculate the reduced level RL of the whole points in the loop and Perform the Arithmetical
Check
2. In which category this work is classified (e.g., first class, second class)?
3. The height difference between point B and the bridge at point N?
