Levelling Survey

Welcome to Levelling Survey!

In this unit, we will explore on different methods of levelling in various instances various methods include chain survey, plane table surveying, use of dumpy level machine. Our journey will cover key concepts such as introduction to levelling, plane table survey, contouring etc, and we will engage in various activities including discussions, projects, or practicals with the instruments.

By the end of this unit, you will have a solid understanding of what levelling entails. I'm excited to embark on this learning adventure with you!

INTRODUCTION IN LEVELLING.

levelling is a fundamental technique in surveying used to determine the relative heights or elevations of different points on the Earth’s surface. This process is crucial in various stages of construction projects, from initial site surveys to final setting out.

Key Concepts Covered:

  1. Levelling Terminology: Understanding terms like datum, benchmark, backsight, foresight, and reduced level.
  2. Types of Levelling: Exploring different methods such as differential levelling, profile levelling, and reciprocal levelling.
  3. Equipment and Tools: Learning to use instruments like the level, levelling staff, and tripod.
  4. Field Procedures: Conducting accurate fieldwork, including setting up the level, taking readings, and recording data.
  5. Data Calculation and Error Checking: Calculating elevations and ensuring accuracy through error checking and adjustments.

Learning Outcomes:

By the end of this unit, students will be able to:

  • Accurately measure and record elevations.
  • Apply different levelling techniques in practical scenarios.
  • Analyze and interpret levelling data to make informed decisions in construction and engineering projects.

CHAIN SURVEY.

Chain surveying is a fundamental method used in land surveying to measure horizontal distances and angles. This technique is particularly suitable for small areas and involves dividing the survey area into a series of triangles.

Key Concepts Covered:

  1. Principles of Chain Surveying: Understanding the basics of triangulation and the importance of accurate measurements.
  2. Equipment Used: Learning to use tools such as chains, arrows, ranging rods, and plumb bobs.
  3. Field Procedures: Conducting fieldwork, including setting up survey stations, measuring distances, and recording data in a field book.

  • Apply various plane table surveying methods to collect and plot data.
  • Create detailed maps and plans based on field observations.

CONTOURING 

Contouring is a surveying technique used to represent the three-dimensional characteristics of the terrain on a two-dimensional map. This method is essential for understanding the topography of an area, which is crucial for various engineering and construction projects.
