1.7 DISCUSSION
rom time to time the leveling e"uipment has to be tested to ma'e sure that the e"uipment had no
damaged that will cause7s error in reading dataA it is important especially if the e"uipment collapse or endure
vibration on the Bourney.
The allowable determined value must be less than 0.00*m (C0.00*). ,f the determine value between in
the range allowable value than the e"uipment can be used. Therefore leveling field wor' can be done. ,f the
determined values are above the range than this e"uipment was not "ualified to be used thus any leveling field
wor' cannot be done with this e"uipment.
Temporary benchmar' can only be used when there is an error to the e"uipment. ,t can be determined
by test the e"uipment before we use it. T he field wor' were called two-peg test. T he obBective is out todetermine if the leveling bubble (bubble axis) and telescope line-of-sight (line of collimation) are parallel.
,f the distance in two-peg test is not the sameA this will reduce the accuracy of the reading value and the
difference value of (e-f) will be larger. ,n this test we will get the value of the end closure e"uivalent to Dero (0).
Two-peg test we can estimate whether the leveling e"uipment can be used or not for leveling field wor'.
This is important to prevent inaccuracy problem in the e"uipment performance.
1.8 CONCLUSION

The two-peg test was succeeded whereby the allowable and the data that we achieved are not
exceeding the allowable limitation value. Plus the collimation line is in horiDontal direction. The error of this two-
peg test limit is not exceeding E0.00*m.
$uggestion for this test is to ma'e sure the observer to ta'e the average value for every staff readingachieved. +ther than that the staff must be stand straight according to the bubbleA the plot and the calculation
have to be determined cautiously. Fith this suggestion we could reduce the errors.

2.6 DISCUSSION
The surveying wor' was carried out at the road which is from the Bunction to the main road to the
1amunia 6each 1esort which is located at Kohor. The road is divided into section and #0 groups is divided to
do the leveling wor' along the road. +ur group is assigned to do a closed loop leveling from section % to section
# and bac' to section %.
rom the T6H that is given by the first group we calculated the T6H# and T6H%. The calculated T6H#
was differing with the T6H# which is given which is differing by 0.3%*. This may happen due to some error that
happen during the leveling is done. Parallax error is one of the errors that will affect the value of the leveling
which is due to the reading that is done by the observer where sometimes the brightness of the environment will
affect the accuracy of the value obtain. +ther than that straightness of the staff will also affect the value cause
when the staff which slightly not straight will cause the reduced the length that is observed.
The difference of the bac'side and foresight is the same as the value difference on rise and fall which
proves the leveling is correct. +ther than that the allowable end closure which is 0.0#/m while the difference for
the end closure is 0.0#0m which is in the range of the allowable end closure. These prove that the value is
acceptable.
!eveling is done to obtain the height difference of two points and to obtain new temporary bench mar'
for the use of construction. 6esides that it is also use for the continue of traverse and tachymetry.
2.7 SUGGESTION
2er e is our suggestion to avoid the error during the field wor' is carried out.
• ue to the place of the field wor' is mountainous area. Fe have to minimiDe the distance between the
level and leveling staff to get the accurate value. The distance is between #* to 30 meters.
• Fe only ta'e the reading from the leveling staff that more than 0.* meter.

• The leveling staff7s bubble must be at the center of the circle.
• To reduce the parallax error. Fe have to ma'e sure the leveling staff in stable conditional and in
verticality.
• Fe also have to minimiDe the line of sight.
2.8 CONCLUSION
rom the leveling wor' that we have done the temporary bench mar' value that we have obtained is
#./%. $o the obBective of this field wor' is achieved. Fe get the end closure is below the allowable end
closure so our leveling wor' can be accepted. rom the leveling wor' we get the reduce level li'e in the leveling
sheet. Fe have analyDed the data and get the allowable end closure is #/.44mm and the end closure that we
have done is #0mm. so the end closure we get is below the allowable end closure. $o we can conclude that our
group obBective to fly reduced level from 'nown point (6enchmar' or Temporary 6enchmar') to un'nown point is

• Process the raw data to obtain the coordinate the area of traverse and the class of the traverse.
• etermined the nature of error affecting the horiDontal control survey.
• Produce a plan using surveying software (trimmap).
3.4 T!EORY
,n survey traverse is defined as the field operation of measuring the lengths and directions of a series
of points on the earth. >ach of these straight lines is called a traverse lie and each point is called a traverse
station. Traverse stations are commonly mar'ed with wooden peg sta'e nail or iron pipe.
Traverse line are measured using total station. Traversing need to start from reference datum
(coordinate bearing and distance are 'nown). &t each traverse station a horiDontal angle is measured and used
to determine the bearing of the next traverse line. These measurements are used to compute the relative
horiDontal position of each un'nown traverse station. The main purposes of traverse are=
• Property surveys to locate and establish boundaries
• $upplementary horiDontal control for topographic mapping surveys
• !ocation and construction layout surveys for highways railways and other private or public wor's

+ur group has been given a site to observe the area of bas'etball court to measure the length and the
direction of a series of straight lines connecting a series of point on the earth. Fe started the field wor' with
observation and decision ma'ing of pic'et point. our () station points have been established which mar'ed
with pic'ets. The location of each pic'et must be free from disturbance and safe. Thus distance from each
traverse station must be more than 30 meters. Travers station also should be numbered continuously using
cloc'wise.
There are few factors which might influence the reading that obtained. There are=
• 2uman factor
The reading not consistence due to many observers recorded the value.
• >nvironment factor
The hot weather disturbed the concentration of observer till hard to focus on prisms.
The soil= $andy soil wea' between connectivity of each particle and not able to apply load on top of it.
$o when the instrument applied at the specific areas the possibilities to obtain error reading more high.
• >"uipment factor
The total station might be not in a good condition.
3.9 CONCLUSION

The tacheometry wor' is a process in civil engineering for plan preparation which it can give the
information about the area of proBect li'e building hill road tree big drain and so on. 6eside the
tacheometry is important to determine high of surface between two points. &ctually the tacheometry
process is depending to the station or pic'et from the traverse and all the items determined by using
the bearing distance and height of control point. &ll the control point that we use as a reference intacheometry was prepared from leveling and traverse process.

The accuracy of distance and difference height that we get from tachometric is lesser than
distance and difference height of traverse or leveling and that7s why the tacheometry is only suitable for
the distance less than *0m. $o the tacheometry is more suitable in wor's that not need the high

5.7 DISCUSSION
,n this surveying we need to set up an area for a proposed building in the area of our traverse
area. Fe need to observe the most suitable area such as no trees that will affect the building and no
obstacle that will affect the view when ta'ing the reading from the station point to the proposed building.
$uitable area for the proposed building is a land which has flat land without any slope but in the area
from our station the most suitable places is only the place that have a slightly sleep slope. ue in real
engineering surveying a perfect place that is proposed would not be true because the area of the
building is fixed and there is no moving around can be done but only finding the most effective way to
get the best result.
rom the result that is observed by surveying from station # and station we found out that
there huge error for the coordinate that has been ta'en and the smallest differ for the coordinate fromboth of the station is. This is due to some problem and errors that occur during our surveying are ta'ing
8/19/2019 SURVEY CAMP REPORT.doc
26/32
26Survey Camp 2010
place. &fter our discussion we agreed that the errors can be divided into 3 types which are caused by
human environment and e"uipment.
irstly for the error that is caused by human is due the carelessness of the observer that is
when ta'ing the reading by shooting from the total station. This will cause parallax error and it will
accumulate if the same mista'e is done by the observer. This problem can be reduced by rechec' byother observer to confirm the answer. +ther than that is by ta'ing the value more than once and ta'e
the average of it.
The accurate location of the total station and the prism when setting the bearing is one the
most crucial time the point of the pic'et to the total station and prism must be rechec' a few times to
reduce the unnecessary error. This error can cause mista'es for every reading ta'en which can
become a systematic error.
The bubble of the pole when is use to set the point of the proposed building point and ta'ing
the measurement is also the mista'es that maybe cause error to our reading. The bubble must beexactly in the middle when the reading is ta'en by the total station. ,n one of the point of our proposed
when the reduced level of the land is very low where it is located at steep area we used two pole that is
connected together and the bubble is used which one of it is on top and another is for the pole under it.
This maybe caused the error where when both the bubble is not at the middle at the same time will
cause the pole to slightly not straight.
or the station we ma'e it very tall to ta'e the reading of the steep area until we have to
stand on chair to ta'e reading maybe will affect the reading as the total station is high up the setting up
of the total station became harder and maybe the total station is not in the exact vertical and horiDontal
place when ta'ing the reading. This caused systematic error that accumulates throughout ta'ing the
reading of every point of the proposed area. This can error can be repaired if the total station is not
located so high up or rechec' a few times is made by a few of observer for the accurate measurement
can be ta'en.
+ther than that our bearing and distance of every point is ta'en by drawing the proposed
building inside the &utoG& and ta'en it into the real measurement. The distance and bearing may
slightly be wrong as our place has slope where the measurement could not be ta'en as a totally
horiDontal line. Heasurement of the vertical distance must be ta'en and calculation must be made to
get the accurate distance which we only realiDe it after that whole surveying is done. This caused thelargest mista'es and error to the whole surveying. The length which is set up is not totally accurate
where errors occurred. This problem can be solve by measuring all the point to the accurate length
using measurement tape of more accurate by using total station and setting up the point at every point
but this will ta'e lots more of time than normal.
The second type of problem occurred is caused by the environment this is when early in the
morning the prism and total station point to view the pic'et and to shoot for measurement is watery and
blur covered by mist caused by cold environment of the area. This will cause the inaccurateness ta'ing
measurement and affect the view of the observer. The mist covering the prism maybe will affect the
laser reflecting shoot from the total station. This problem can be solved by exposing the e"uipment tothe sun for a moment to clear the mist or by cleaning using soft material such as tissue.

The hot weather also will affect the reading of the total station as hot environment will cause
the blurry view when shooting to the prism. +ther than that the brightness of the sun will cause uneasy
to the eye when trying ta'ing the reading. $olution for this problem is to wait for a better weather but
this is not a very suitable cause it will delay the time for the Bob to be done.
The third type of problem is caused by e"uipment the total station pole and the bubble thatalready have errors will cause systematic error to the reading ta'en as the error accumulate from the
starting of the surveying is done. This problem can be reduced by chec'ing the e"uipment from time to
time for the best performance of the e"uipment.
&ll this problems that occur affected our result and caused the differ of the coordinate that is
ta'en from both of the station.
5.8 CONCLUSION
,n setting out surveying we are exposed to the real situation and problem solving thin'ing that
is needed facing a lot of possible problems during construction. early precaution must be ta'en before
starting a construction to lower the possibilities of problems that will happen. The most important of all
we have gained more 'nowledge and experience to face the future on construction setting out area for
the use of construction.

&s a conclusion each of the members of our group gained some benefits through $urvey
Gamp %0#0. rom the camp that being held especially for us we learned the proper method to handle
and operate with the survey e"uipments included how to process the data from two-peg test leveling
traverse tacheometry and lastly setting out wor'. 6esides that we also 'new the method of plotting and
contouring to get topography and manmade features by using trimmap and &utoG& for our group7s
site survey that is bas'etball court in 1amunia 6each 1esort.
,n this programmed we able to understand the method to form full field wor' plan by group.
6efore this we Bust learned theoretically in the class but the process and percentages of understanding
in students mind are less than the understanding that we gained through this programmed practically.
Practical help us more than theoretically because when we understand and apply the theory in the real
world.
