Question

175, 193 D. 62.2, 70 6. A site-plan shows the proposed grade for a construction project and the elevation at each station is cquired through profile leveling. How will the amount to cut or fill at each station be calculated? elevation - proposed grade B. BS - FS C. This is equal to the error of closure D. HI FS 7. It is necessary to determine the amount to cut or fill at each station along a profile where it is not possible to place stakes at the proposed grade. Thus grade rod is calculated from A HI-proposed grade B. The amount to cut C. The amount to fill

Explanation / Answer

6. By using the profile leveling instruments, the elevations at each station is calculated with reference to the bench mark. Then the amount of cut or fill will be equal to the difference in elevation and proposed grade or elevation. So, the answer is A.

7.When it is not possible to calculate the amount of cut and fill where there is not possible to place the stakes, then the grade rod is calculated from the difference in Height of the instrument and proposed grade.
