PRACTICAL : TWO PEG TEST

1.0 OBJECTIVE

Purpose of doing this test is to determine the collimation error of a level instrument.

2.0 LEARNING OUTCOMES

1. Apply correctly the fundamental principles and practices of surveying work. (C3, PLO 1)

3.0 THEORY

All instruments are subject to errors. The checking of the instrument (in this case level) is therefore
important. The main error is where the line of sight is not parallel to the horizontal line of collimation. In this
case levels will not be correct. A test for checking the level is known as the two peg test. Two peg test
must be carry out before starting the levelling job to insure the instrument in good condition. This test
determines the amount of errors and if an error occurs notify the technician (the level must be serviced)

4.0 INSTRUMENTS

a) Automatic level.
b) Tripod.
c) Staff.
d) Staff bubble.

5.0 PROCEDURE
1. Depending on the exercise area use pegs or a spray can to mark two points.
2. The points should be set up at a distance of 40 metres apart.
3. Use pegs on grass to mark points.
4. Set up the level midway between the points.
5. Take the staff reading (three (3) decimal places) at point A and B and record them in row one
(1) of the table.
6. Calculate the difference between the two readings and record it in the table.
 7. Move the level to a distance of approximately 4 metres opposite the staff position behind the
point A or B.
8. Take the staff another reading for both point A & B again and record them in row two (2) in the
table.
9. Calculate the difference between the two readings and record it in the table.
10. Check whether the differences between the readings are the same or not.

Noted:
If this is not the case and difference is not within the specified value then you need to repeat the test
or the instrument needs to be serviced.

If the collimation error is found to be less than about ± 2mm per 20m or some specific value the level assumed to be in adjustment. If
the collimation error is found to be greater than about ± 2mm per 20m or some specific value the level has to be adjusted.

1.0 OBJECTIVE

This practical deal with determination the reduced level in given task. Student should be able conducted the
experiment according to the requirement, accomplish the task within a duration of time given and document
the task and produce the report.

2.0 COURSE LEARNING OUTCOMES

1. Perform appropriate measurement techniques and principles in fieldwork using standard procesure and
current survey instrument. (P4,PLO5) (P4,PO5)
2. Demonstrate positive leadership and team work by contributing actively in groups during fieldwork that
yield valid results. (A3,PLO11) (A3,PO09)

3.0 THEORY

The elevation of a point, above or below datum is considered as vertical distance. The value of mean sea level
as datum is reference or control point to determine the elevation of desired points. The operation of
determining the difference elevation of points with respect to other point on the surface of the earth is called
levelling.

4.0 INSTRUMENTS

a) Automatic level.
b) Tripod.
c) Staff.
d) Staff bubbles.
e) Peg
5.0 PROCEDURE
a) Let A and B be the two point and the level is set up between A and B anywhere in the ground. A is a
point of known elevation, TBM1 = ……….. m.
b) The telescope is directed towards A and reading vertically held staff at point A. This is B.S reading
=…………… m.
c) The telescope is directed on the staff at point B. The F.S reading is ……….. m.
d) Then move level at any stable ground between next point B and C.
e) Repeat the procedure b) and c). Also take reading for B.S and F.S.
f) Repeat the procedure until the unknown point. Then close the reading to TBM1.

PRACTICAL : LONG SECTION AND CROSS SECTION SURVEY

1.0 OBJECTIVE

This practical deal with determination the reduced level in given task. Student should be able conducted
the experiment according to the requirement, accomplish the task within a duration of time given and
document the task and produce the report.

LONGITUDINAL OR PROFILE

1.1. Provide data from which a vertical section of the ground surface.
1.2. Determine the elevations or reduced level.
1.3. Determine cross-section.
1.4. Plot cross-section.

CROSS-SECTIONING

1.1. Determine the elevation of the points at right angles on either side of the center line of the
proposed route.
1.2. Find out the vertical sections of the surface of the earth on the ground.
1.3. The detailed information regarding the levels of the ground on the either side of the longitudinal
section helps in calculating the quantity of earth work.

2.0 COURSE LEARNING OUTCOMES

1. Perform appropriate measurement techniques and principles in fieldwork using standard procesure
and current survey instrument. (P4,PLO5) (P4,PO5)
2. Demonstrate positive leadership and team work by contributing actively in groups during fieldwork
that yield valid results. (A3,PLO11) (A3,PO09)
3.0 THEORY

It is the operation to determine the elevations of points spaced apart at known distances along a given line
in order to obtain the accurate outline of the surface of the ground profile. The purpose of profile leveling is
to provide data from which a vertical section of the ground surface along a surveyed line can be plotted.

b) Set up the points at right angles on either side of the center line of the proposed center line.
c) Set up instrument at any suitable points, a number of change points, CP along with intermediate
sights, IS may be required.

of slope and other critical points.
