pole was 148.61 ft. The theodolite optical center was 4.66 ft above the upper base
line station at 110+71.25.
A. If the elevation of the upper station was 829.76, what is the elevation of the
lower station?
What is the chainage of the lower station?

8. Plan-view sketches of benchmark leveling runs are shown below. Along each
line representing a sight is the value of the rod reading for that sight. The
numbering of the TPs shows the direction of level run. Place the data in the form of
the field notes. Include the arithmetic check. Assume that the average length of
each BS and FS is 40m; determine the order of accuracy of the survey.
