Engineering Project Survey
Introduction
In engineering. surveying plays the important role of helping experts to identify the different
distances. elavations. and angles that specific pieces of land where the projects are to done on.
allowing for the accurate design of these projects. This report details an accurate description of
the land situated around the EXT BUILDING 28. EXT BUILDING 29. and BUIDLING 30
through a survey procedure using a total station. The results of these procedures will be utilized
for purpose of producing a contoured and detailed survey of the area marked by these buildings.
Theory
The elevations are identified through a levelling experiment where the elevation of a known
point also refered to as the benchmark is utilized itogether with the readings read on a leveling
rod. There are two types of rod readings, namely the subtract rod readings (FS) and the (BS)
which are called the subtract rod readings. Manipulation of these points in reference to a known
elevation point known as a benchmark enable surveyors to establish the elavations of unknown
points from the line of sight. This is demontrated in the following schematic.

ENGINEERING SURVEY 3
Methodology
For this experiment. the required equipment which included a total station was obtained.
and the appropriate Bench Marks (BMs) and the Temporary Bench Marks (TBMs) were
identified. The instrument was then checked before any surveying work was conducted to e n
sure that all the required adjustments are taken care of in the field to make the instruments
accuracy appropriate for the siad space. This also guarantees that the calculations are also
accurate. This includes ensuring that the 2-peg test procedure is carried out in the field and is
also included as part of the recorded readings. It also important to ensure that all the observations
are noted down in the level book during any visits to the site. Ensuring the equipment is well
adjusted to avoid conducting correction computations.

ENGINEERING SURVEY 4
For the reduced levels computation. the following table was filled with all the recorded values
from the field. The leveling excersice was conducted in order to go back to the initial point. and
thus do the the reduced check to get more accurate readings (Bliakharskii & Florinsky, 2018).
i) For Angle and Distance Measurement
After getting the reduced level for the TBM-1 position. the angle and distance measurements
were establsished using the horizontal and vertical measurememnts required for completeing the
plotting. The vertical and horizontal measurements between the different TBMs were taken using
a total station. To use the total station. the equipment was set up at TBM-1 and reflectors were
placed. The readings on the reflectors for both the left and right faces were indicated. as well the
height of the instrument (H1). the height of the target (HT). the horizontal angle (HA). the
vertical angle (VA). The distance –slope (DS) is also measured. as well as the distance horizantal
(DH). and the distance vertical (DV). The whole circle of bearing (WCB) for this station was
also measured (Bliakharskii & Florinsky, 2018).
The reduced levelling for TBM1 data was computed using the rise and fall method and is
depicted below.

ii) In the measurement of angles and distances using a total station, the average length of
the tranverse sides of the sites are established first through halving the sum of the
direct distance and the reverse distance measurement values

ENGINEERING SURVEY 6
To estimate the average length of the tranverse sides the interior angles have to be estimated
using the following formula
∑ interior angles= ( n−2 ) 180
∑ interior angles= ( 6−2 ) 180=720 degrees
Thus the length is then estimated using the direct measurements as indicated in the folloowing
table.

Error calculation and adjusted angle.
Adjusted angle calculations are also established through identifying the average correction or
number of readings collected in the field the misclosure and dividing itt by the total. This value
which is also known as the multiple average correction is also rounded of to the nearest smallest
increment of angular measure. The next difference is then rounded off to the same value of 2.5”
and then added to the measured anngle in order to yield the adjusted angle. The sum of the
adjusted angles should add up to 180°00’00”.

Discussion and Conclusion
This survey is a depiction of the area around EXT BUILDING 28. EXT BUILDING 29. and
BUIDLING 30. The survey conducted has illustrated minimalistic errors which can only be
attributed to miscalculation, human error while in the field collecting the data or even natural
factors. These errors have negative and adverse impacts on the efforts undertaken during a
surveying exercise as very minor miscalculations or human eror mistakes could greatly cost the
integrity of the survey (Shan & Toth, 2018)
While conducting the survey, immense precautions were taken to gurantee that any mistakes that
occur in the early stage of the surveying procedure do not impact the creativity of the following
stages. For instance, extreme care was taken in order to minimize the occurrence of any errors
that could be limited (Drake, Roos, Conrad, & Stack, 2017 ) of skills and insights were also
shared during the experiments, and this new knowledge will go a long way in the future
surveying exercises that will be conducted in both our academic and professional lives. This
specifically helped with understanding surveying equipment and how the equipment is used and
ow errors in this experiment can be avoided to avoid miscalculations in the future.
