A Civil Engineer proceeded to do the stadia survey work to determine the topography of a certain area. The transit was set up at a point A, with the line of sight horizontal, took rod readings from the rods placed at B and C which is 200 m and 60 m from A respectively. Stadia constant is 0.30 m. Rod B Rod C Stadia Interval 2.001 m 0.600 m Draw a diagram of the entire problem. Compute the stadia interval factor (clue: if there are more that 1 value, get the average) The same instrument was used for determining the elevation of point D with a stadia intercept of 2.12 m and a vertical angle of +4°22’. If the elevation of the point where the instrument was set up is 100 m, compute the elevation of point D given the middle reading of the stadia is 1.892. Compute the horizontal distance from the point where the instrument was set up to point D.
1. Given the following tabulations are observed and calculated data for a traverse. Balance the latitudes and departures by the COMPASS RULE and compute for the area of the closed traverse by DOUBLE PARALLEL METHOD (DPD). Tip: Before you compute for the area of the closed traverse, you must first adjust the latitudes and departures.
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 the level run. Place the data in the form of field notes. Include the arithmetic check. Assuming that the average length of each BS and FS is 145 ft, determine the accuracy of the survey.

A link traverse has been conducted between two temporary benchmarks of known elevation and includes an inverted staff measurement at the underside of a bridge. The known reduced level of TBM 47 is 52.716 m and the known reduced level of TBM 48 is 51.227 m. What is the misclose, in mm, of the levelling traverse? After correcting for misclose, what is the corrected reduced level of the underside of the bridge? Apply your misclose corrections on the basis of distance (assuming the misclose accumulates linearly with distance during the survey). Answer in meters.
