- Surveying Question: A differential leveling circuit starts at benchmark Concrete Benchmark (Elevation=232.051m) goes out to an unknown benchmark and then continues to a known control point (Elevation=227.975m). Two turning points are used with the measurements included in the attached table. Determine the elevation of the unknown benchmark Determine the order and class of the survey. For First order Class 1: Allowable Error= +/- 4(K)1/2 Range of Constant= m less than/equal to 4 For First Order Class 2: Allowable error= +/- 5(K)1/2 Range of constant= m greater than/equal to 4, and m less than equal to 5 (between 4 and 5) For Second Order Class 1: Allowable error = +/- 6(K)1/2 Range of Constant = m greater than/equal to 5, and m less than equal to 6 (between 5 and 6) For Second Order Class 2: Allowable error = +/- 8(K)1/2 Range of Constant = m greater than/equal to 6, and m less than equal to 8 (between 6 and 8) For Third Order, Any Class: Allowable Error = +/-12(K)1/2 Range…When measuring a distance AB, and with respective to facing towards point B when standing at point A, the first taping pin was placed 1.35 ft to the left of line AB, the second pin was set 1.89 ft left of line AB, and the third pin was set 1.52 ft to the right of the line AB as the survey team attempted to correct their prior placements badly. The recorded distance was 734.33 ft. Calculate the corrected distance. (Assume four taped segments, the first three 200 ft each.)A level loop was run and the raw elevations in Table 2 were calculated based on backsights and foresights. A plan view of the loop is shown in Figure 2. The true elevation of BM1 is 195.00 ft. Adjust the elevation of each station such that the error is evenly spaced. Show sample calculations of your work.

A two peg test is used to check whether the line of sight is in perfect adjustment and the following rod readings are taken, with instrument set up near A, on A is 1.623 m and foresight reading on B is 2.875 m with the instrument set up near B backsight on B is 1.622 m and a foresight on A is 0.362 m A. Compute the difference in elevation between A and B . B. What should be the correct rod reading on A to give a level line of sight with the instrument still set up at B? C.
