This document provides information from a surveying camp, including: 1. Coordinates of existing buildings that were determined through field observations. 2. A table of leveling observations and reduced levels taken along a ground profile. 3. Graphs plotting the building coordinates, ground profile, and layout of a simple circular curve determined through deflection angle calculations.

Profile Leveling and Plotting of L-section of Ground
Profile or L-section:
It is the graph between distance and reduce
levels of ground or road. In case of road
profile levelling the level of the road can
be determined at different points by
reading the road profile level.
Distance:
Total ground length taken 300 meters and
take the readings at the interval of
10meters

Layout of Building Plan or Marking of
Columns and Grids
The process of laying out (setting out) of a building or structure is an important
part of surveying, as it enables the works to proceed on site exactly according to
the prepared designs. It constitutes of marking boundary walls or grids (center
line of columns) by using Pythagoras theorem method.
