Survey Markers and Monumentation - Quiz

Quiz Question

1. Specifications on naming criteria, standard installation procedures, and accuracy classifications were adopted in part from the__________________________.
National Geodetic Survey (NGS)
National Geographic Survey (NGS)
2. Monuments and their stability are integral parts of the accuracy of each survey project.
True
False
3. Permanent monuments shall be defined as monuments that are set in relatively stable material or in a structure for the purpose of preserving the location of either a horizontal control station, the elevation of a point above an adopted datum (bench mark), or the location and/or elevation of any point of special significance when its preservation is required permanently or for longer than 2 years.
True
False
4. _____________________ markers shall be defined in the same manner as permanent monuments except that preservation is only required for a period of 2 years or less.
Temporary
Permanent
5. The purpose of the ____________ government and its contractors is to serve the public.
Federal
State
6. A mark setter exercising good judgment is defined as an individual who thoroughly evaluates the security, utility, stability, environment and safety of the mark and its site before establishing the marks.
True
False
7. Structures that are of themselves suitable for mark settings do not prevent vehicles and equipment from damaging marks that are set adjacent to them.
True
False
8. If the mark cannot be found or if the site cannot be conveniently occupied, it’s worth is not questionable.
True
False
9. LOP is abbreviated as __________________.
Lines of Path
Lines of Position
10. The more nearly perpendicular the angle at which LOPs intersect, the more accurately a position may be determined and the easier it will be to locate the mark.
True
False
11. The crest of a hill is a good location for a monument because:
The problem of slope instability is eliminated
The frost heave is less likely with the increased separation from the water table
The consistency of the soil will tend to be more firm
All of the above
12. The fraction of grain sizes less than ________ millimeter governs whether or not a soil is frost susceptible.
0.01
0.02
0.03
13. Since structures are subject to movements, fixing a mark on a structure does not assure that it will be a good geodetic control point.
True
False
14. Trees, underbrush, grass, and moss act as insulation, increasing the depth of the active frost zone and thus increasing frost heave.
True
False
15. The stability of a large structure may be related to a Type B rod mark by comparing the depth of the structure’s foundation to the required depth of the rod mark sleeve.
True
False
16. The __________ rod mark sleeve is set to a depth below that affected by expansive soils and frost heave.
Type A
Type B
Type C
17. The rate at which a material will corrode or deteriorate is not affected by its environment.
True
False
18. The greater the ability of the electrolyte to carry current, the ____________ corrosion will occur.
Slower
Faster
19. The more resistant a soil, the poorer the electrolyte and consequently the less corrosive it will be.
True
False
20. Hydrants usually are not placed within a meter (40 inches) of the line and to the side away from the street centerline.
True
False
21. Telephone and electrical cables are normally laid from ____________ below the surface.
0.5 to 1 meter
1.5 to 2 meter
22. Any obstructions above ____________ will potentially block satellite signals.
5 degrees
10 degrees
15 degrees
23. ______________ rod marks should be used when sound bedrock or substantially stable structures are not available.
Type A
Type B
Both the above
24. The type A mark should be used in highly corrosive environments.
True
False
25. Figure3-1 represents ___________________.
Type A monuments
Type B monuments
Type C monuments
