whose elevation is known.
true
The average height of the sea for all stages of the tide after long periods of observations is
known as
mean sea level
Clearing, stripping, grading, and drainage are done essentially at the same time as part of
which earthwork operation?
pioneering
During which earthwork operation are roots and stumps uprooted and removed?
grubbing
During which earthwork operation are objectionable topsoil and sod removed and disposed
of?
stripping
What is the construction of facilities to allow excess surface and subsurface water to flow
from the construction site?
drainage
(True or False) Permits are only acquired before a construction project begins.
false
To correct an engineer’s level that is not quite horizontal, what action should you take first?
Slacken the reticle adjusting screws
You can bring the vertical cross hair of the dumpy level into exact alignment by rotating
which of the following components?
azimuth tangent screw
What type of level was designed to eliminate the use of the tubular spirit level?
self leveling
A self-leveling level automatically gives a level line of sight when the level bubble is
approximately within the center of the
bulls eye
What type of level is used for short distance sighting and has no magnification device?
hand
When removing a level from its case, you should grip what part?
the footplate
(True or False) An engineering level should be stowed in its carrying case when not in use.
true
In the target reading method of surveying, who reads the rod?
the rodman
On a Philadelphia rod, the large numerals indicating foot markings are in what color?
red
When the instrumentman is unable to read the foot markings on a Philadelphia rod, he
gives the command RAISE THE RED. What should the rodman do?
raise the rod
On a Philadelphia rod, the vernier scale helps you make readings as small as what fraction
of a foot?
1/1,000
(True or False) When the rodman finds it difficult to hold the rod perfectly plumb, it should
be waved back and forth to allow the levelman to read the lowest reading touched by the
crosshair.
true
Differential leveling has what purpose?
finding the vertical difference between two points

density occurs.
true
Which is a purpose of soil stabilization?
all of the above
