GIT | CIVIL | SURVEYING LABORATORY (CEC505)

Rationale

As it is always said “well begun is half done”. All civil engineering projects such as buildings, roads,Bridges, railways, airports, dams, water treatment plants, sewage treatment plants begin with surveying. Knowledge of surveying is thus fundamental and very useful to all civil engineers. In this course, the students are well informed about the principles and methods of surveying. The students are made conversant with various instruments which are used in the field to take measurements for preparation of drawings. The course introduces the advancements in instruments and methods of surveying. The study deals with the methods of computing land areas and volume of earthworks. The course also covers horizontal and vertical curves.

Objectives

On successful completion of the laboratory course, the students shall be able to understand:
1. The basic principles and classification of surveying.
2. Various methods of measurements in surveying.
3. The appropriate techniques of surveying and skills of collecting field data for preparing drawings.
4. Advancements in instruments and methods of surveying.
5. The methods of computing areas and volumes using the site specific data for various purposes.
6. The setting out techniques of curves. The properties of fluids, units and dimensions.

Outcome

On successful completion of the laboratory course, the students shall be able to understand:
1. Apply the principles of surveying and field procedures to conduct the various surveys.
2. Use various methods for taking linear and angular measurements.
3. Collect, record and analyse the field data for preparing drawings.
4. Explain the advancements in instruments and methods.
5. Calculate the area of land and volume of earthwork.
6. Set out curves.

List of Experiments

1. Chain and cross staff surveying.
2. Measuring bearings of a closed traverse with prismatic compass and computation of interior angles.
3. Simple and compound levelling
4. Measurement of horizontal and vertical angles.
5. Finding constants, heights and distances using tachometry.
6. Measurement of distances, bearings and area using total station.
7. Plane Table Surveying by intersection method.
8. Find an area of irregular figure using a conventional planimeter and verify it using a digital planimeter.
9. Setting out a simple curve by Rankine’s method.
10. Setting out a simple foundation plan.

List of Projects

1. Project I: Road project using Auto level for a minimum length of 500 m including fixing of alignment, profile levelling, cross-sectioning at 20m interval,, plotting of ‘L’ section and ‘C’ section. (Two full imperial sheets, the first sheet with key plan and ‘L’ section and the second sheet covering any three typical Cross-sections)
2. Project II: Block Contouring project using Auto level for minimum 60 m × 60 m area and generating contours by MS Excel. (Take contour interval as 0.2 meter).
3. Project III: Tachometric contouring project on a hilly area with at least two instrument stations about 60 m to 100 m apart and generating contours by taking contour intervals as 1 meter.
