Levelling & Setting Out Surveyor Refresher Course
The purpose of this short course is to develop levelling skills required for setting up a levelling instrument, transferring levels, bookings levels and setting out excavation profiles and to develop basic setting out skills required for using a metric tape, survey accessory equipment, preserving survey points, using ranging rods, setting out right angles and controlling levels.
Description
The purpose of this short course is to develop levelling skills required for setting up a levelling instrument, transferring levels, bookings levels and setting out excavation profiles and to develop basic setting out skills required for using a metric tape, survey accessory equipment, preserving survey points, using ranging rods, setting out right angles and controlling levels.
This course is designed to give junior surveyors, engineers and personnel in the surveying and construction industry a good grounding in the principles and practical application of levelling for both Topographical Survey and for Setting Out. The course is aimed at students with little or no previous experience of using levelling equipment. The course includes the observing, calculation and checking of levelling runs using the ‘Height of Collimation’ method of booking as well as checking the equipment. Field practical exercises are used to back up the theory learned in the classroom. An automatic optical level, manually booked is used for all exercises. A basic knowledge of the use of calculators for addition / subtraction, multiplication / division and square roots prior to coming on the course would be an advantage.
Course Objectives
• Set up and use automatic levels and laser levels.
• Read the level staff, book and reduce levels.
• Understand sources of error in leveling.
• Check the level for collimation error.
• Establish a working temporary benchmark on site.
• Observe, record and calculate the level of existing features.
• Set out given level values, including soffits.
• Calculation of drainage run.
• Set out profiles and calculate travellers.
• Set up and use modern electronic theodolites.
• Complete collimation checks on the instrument in the field.
• Extract setting out data from drawings.
• Calculate bearings and distances from coordinates for setting out.
• Set out points for building work using a theodolite and tape.
• Correct tape distances for slope, temperature and tension.
• Read and record angles and distances for checking position.
• Use theodolite for horizontal and vertical alignment.
Who is this Training Course for?
The course is designed for site managers, foremen, supervisors and trainees who are required to level points and set out defined heights for construction and civil engineering work.
Prerequisites
Little or no previous experience is required, but some basicunderstanding of the need to use levels and transfer height information is desirable.
