|
|
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. |

|
|
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. |
