Full Unit-wise Syllabus

List of Experiments

• Levelling Operations: Fly levelling, check levelling, and benchmark transfer.
• Contouring and Mapping: Grid levelling, contour mapping, and cut & fill volume estimation.
• Theodolite Surveying: Measurement of horizontal angles by repetition and reiteration methods.
• Total Station Surveying: Angle, distance, coordinate measurement, orientation, and resection methods.
• Height and Distance Measurement: Determination of height using REM/trigonometric methods.
• GPS Surveying: Navigation and feature collection using handheld GPS.

Activities: (Perform any 2 tasks) 1: Site Levelling and Earthwork Estimation: Perform levelling and contour mapping to estimate cut and fill volumes for a construction site. 2: Precision Survey and Layout: Measure horizontal angles using theodolite methods and apply them for setting out a simple structure. 3: Total Station Mapping: Conduct a topographic survey using Total Station and prepare contour and feature maps for planning. 4: Height and GPS Survey: Determine heights using REM method and integrate GPS data for mapping infrastructure features.

Course Outcomes (COs)

• CO1: Perform levelling and angular measurements using conventional surveying instruments.
• CO2: Apply modern surveying tools (Total Station and GPS) for field data collection and mapping.
• CO3: Analyze survey data to prepare maps, contours, and compute elevations and distances.

Assessment Pattern (Quick Note)

• Weightage: Continuous Assessment 60% | End Semester Examinations 40%
• Internal methodology: Project (30%), Assignment (10%), Practical (30%), Internal Examinations (30%)
