The course involves a series of presentations by PowerPoint and practical exercises (both in the training room and outside) to ensure delegates understand the theory and practice of levelling and setting out of heights. Discussion encourages delegates to question their techniques and results to ensure they get the exercises right.
The delegates will improve their understanding of levelling equipment and techniques and appreciate the need to apply a Quality Control system to ensure results are correct, checked and documented to prevent costly mistakes on site.
Course Outline:
The course is designed to enable delegates to:
- Understand the basic concepts of Levelling
- Understand the different types of level datums
- Understand the differences in types of levelling equipment
- Apply the procedures for setting up and reading an optical level and staff
- Undertake a level loop to transfer a site datum – book and reduce correctly
- Undertake a set of levels to height a series of points – book and reduce correctly
- Understand the nature of errors and how they apply to levelling
- Understand the need for Quality Assurance/Control
- Undertake a ‘Two-peg Test’ to check instrument adjustment
- Understand the different methods of setting out heights
- Understand the concepts of gradient for engineering work (drainage, earthworks etc.)
- Undertake calculation of gradients for a drainage run
- Set out defined heights for different applications (finished floor level, footings & drainage runs)
- Understand how lasers are used in the construction industry
