Introduction

2. 2
In profile leveling, you determine the elevations of a series of
points lengthwise along a highway (a road). In cross-section
leveling, you determine the elevations of points on a succession
of lines running at right angles to the lengthwise line of the highway.
The principal purpose of profile leveling is to provide data from
which the depth of fill or cut required to bring the existing
surface up to, or down to, the grade elevation required for the
highway can be determined.
To design linear facilities such as highways, railways, transmission
lines, canals, sewers and water mains, engineers need accurate
information about the topography along the proposed route. Profile
leveling, which needs elevation at definite points along a reference
line, provides the needed data.
Equipments
 Auto Level
 Staff
 Tripod
 Measuring Tape
 Marker (Spray)
 Pen, Paper, and Calculator
Procedure
Steps of the test:
1. Stationing the reference line.
2. Points (stations) are marked. Stations are set at starting and
ending points, at center line and both sides of center line, then
intermediate stations. Distance between stations is 20 m.
3. Setup Level and take readings of all stations.
4. Collect data and sketch the diagram.

Result and Conclusion
In this experiment we worked in field and we obtained desired data.
From the profile run, we know the center-line elevation at each
station. And we take cross-section elevations at (0+20 m) for center
line and both sides of the center line.
On the plot of the profile we note that the road line is slope, it
decrease when we move from left to right.
From the second chart we see the croos-section of the road and we
note that the center line is higher than both sides (right and left).
