REPORT OF LEVELING SURVEY

INTRODUCTION
In this project, a leveling survey was done to determine the elevation of manhole covers near Stafford Bridge. An open loop has been achieved here by starting and ending the survey from the same OBM. The measurements were entered in a booking sheet and the reduced level at each location was then calculated using the Height of Collimation (HOC) method. These calculations of reduced level were then checked for accuracy. It was used to determine the elevation of the center of the bridge. This report presents the process of reduced level calculations with the discussion of the methods used.

CALCULATIONS
Table 2 shows the calculation of reduced level at each location using Height of Collimation method. The accuracy check also is done here to determine the error of recordings.

REPORT OF TRAVERSE SURVEY

INTRODUCTION
A traverse survey was done using the Total Station to measure the distances and angles of a traverse polygon. The polygon established for this project has three survey stations and three lines. Data was measured and recorded for all three stations. Angles were measured using Face-Left and Face-Right method and calculated the average. At the same time, horizontal lengths of the lines were measured. Then the data were recorded in the recording sheet. Internal angles were calculated and error of the total of the angles was compared with the allowable limits of the error.

CALCULATIONS
Internal angles of the polygon was calculated and given below.
BAC = 53º 56' 27"
CBA = 79º 17' 42"
ACB = 46º 45' 02"
Total of the internal angles of the traverse = 53° 56' 27" + 79° 17' 42" + 46° 45' 02"
= 179° 59' 11"
The sum of the internal angles should be 180(n + 2)° = 180*(3-2)º = 180º
