The document contains details from 4 site observation and leveling activities conducted between January 10-18, 2018. It describes the leveling process and measurements taken between different points on the CUTM campus, including from the Triangle to the ITI block (0.52m difference), and from the ITI block to the ground (-9.96m difference). The level differences were calculated using the rise and fall method or HI method, with level readings taken using a dumpy level, staff, tripod, and taps.

3. Activity No: 02 Date: 10-01-2018
Leveling
Name of the Place: Triangle to ITI block in CUTM, Campus.
THEORY OF LEVELLING
Levelling is a process of transferring height of a “datum” from one point to another. It is used
in engineering to establish building elevations, layout of highways, determinations of flood
plains, calculate volumes in earthwork, design and layout of sewage and water lines, develop
topographic maps, and student crustal-earth movements.
Levelling operations is a level readings can be taken either from one location (one-set-up
levelling) or from various stations, if some points of interest are not visible. A level survey
can be used for setting-out purposes, the presentation of soil profiles etc., as will be discussed
later in the subject.
Basic definitions of Back sight (BS) first staff reading taken immediately after setting up the
instrument.
Foresight (FS) last staff reading taken before moving the instrument to another location.
Intermediate sight (IS): all readings taken between a BS and FS.
So if the instrument is set up at one location only, there will be just one BS (first reading to a
TBM). One FS (last reading) and several IS.

4. Instruments Required:
 Dumpy level
 Leveling Staff
 Tripod Stand
 Taps
Procedure:
 Let A and B the two points as shown in fig. the position of each setup of level should
be selected that staff kept on the point visible through the telescope.
 Let O1, O2, O3 be position of the level to be setup, choose the change point 1.2 etc.
on the ground so the position of the level should be midway between two staff
reading.
 Now setup the level O1 take the reading on the staff kept vertically with bobble
central.
 This will be a back sight.
 Now select the position of C.P.O so that distance of it from O1 is approximately equal
to that O1.

5.  With the bubble in the centre take the reading the staff held vertically, over the change
point.
 This will be fore sight continuous.
 Now shift the level O2 and setup it there carefully, with the bubble then kept
vertically as the fore sight over C.P (01).
 This will be back sight in the same line.
 Select another C.P (02) on the ground and level with the bubble kept reading.
 This will be fore sight in the level in the next line.
 Repeat the process until the point B.M reached.
 The least reading will be fore sight.
 Now find out the RL by HI methods or by rise and fall method.
 Apply the arithmetical check.
Observationand Calculations:
Now, we are going to be calculate by using the rise and fall method.
∑BS - ∑FS ∑RISE - ∑FALL
= (6.00 – 5.45) = (2.280 – 1.73)
= 0.55M. = 0.55M.
Hence, by using rise and fall method we found that the level difference from triangle to ITI
block was 0.55m.

6. Conclusion:
 After completion of this experiment we found that the level difference from triangle
to ITI block was 0.55m.
 We calculated by using the rise and fall method.
