D. 115 ft 11 in B. 75 ft 0 in. 60^2 + 45^2 = diagonal ^.5 = 75 ft Assume you have a right triangle with a hypotenuse of 310 ft.

A. 106.03 B. 112.84 C. 291.09 D. 851.73 A. 106.03 A rod reading of 4.72 ft is taken on a benchmark whose elevation is 813.30. The finish floor is 809.00. The top of the batter board is set 1 ft above the finish floor. What rod reading is required to set the line for the top of the batter board? A. 4.30 B. 5.30 C. 8.02 D. 9.02 C. 8.02 (813.3 + 4.72) - 810 = 8.02 What does the surveying abbreviation TP mean? A. tangent point B. turning point C. traverse point D. terminal point B. turning point Using Figure 9-13, what is the benchmark elevation at IP #4? Starting pg 131/137 A. 864.62 B. 889.90 C. 896.27 D. 902.64 B. 889.90 You are required to establish grade to the bottom of a footing that is 1ft thick. The elevation at the top of the footing is 102.33 ft. The backsight of the instrument on the benchmark of 100.00 ft is 6.78. What is the correct reading of the rod at the bottom of the footing? A. 0.64 B. 3.81 C. 4.45 D. 5.45 D. 5.45 . (100 + 6.78) - (102.33 - 1) = 5.45 The job site has a primary vertical control point with a reference benchmark of 100 ft. An instrument is set up with an HI of 5.42 ft above the BM. A grade stake is set at an elevation of 96 ft. What is the height reading on the rod at the grade stake? A. 1.42 ft B. 4.00 ft C. 5.42 ft D. 9.42 ft D. 9.42 ft • 5.42 + 4.00 = 9.42 ft or • 105.42 - 96.00 = 9.42 ft Using the information provided in Figure 11, what is the benchmark elevation at IP #4? A. 864.62 B. 889.90 C. 896.27 D. 902.64 B. 889.90 • 877.26 + 19.01(total BS) - 6.37 (total FS) = 889.90 A superintendent wants to check if a 25' high block wall is within tolerances.
