aerial photographs
3.
An instrument survey of the
desired location
4.
An inventory of available
construction equipment
12-3.
Direct air observation of an area
to be reconnoitered offers what
main advantage?
1.
Acquiring information about
the relief of the area
2.
Providing a quick means of
preparing sketches of the area
3.
Speeding subsequent ground
reconnaissance of the area
4.
Providing a quick means of
preparing maps of the area

As the lead surveyor laying out the
final location of a roadway center
line, you suspect that the
preliminary survey was in error
regarding the exact location of the
center line.
Which of the
following actions should you take?
1.
Lay out the center line
according to the preliminary
data
2.
Lay out the center line the
way you know it should be
3.
Lay out the center line and
then report the reason for
making the necessary change
4.
Report the problem and receive
authorization before making
the location change
12-8.
Which of the following details must
be shown on a plan view of a
proposed highway?

2.
Gradient
3.
Spot elevations
4.
Typical cross section of the
highway
