Portfolio of Surveying Task

By the end of this course students will be able to calculate and adjust survey data to analyse errors and derive unknown bearings, distances, coordinates, curve elements and areas to include:
● vertical control
● Description of types of control points.
● Primary controls, first and second order.
● Secondary control.
● Carrying out a full closed traverse survey for horizontal and vertical controls.
● Methods for checking the accuracy of the traverse.
● Purpose of a topographic survey.
● Techniques to communicate a completed survey.
● Methods of completing a topographic survey.
● Equipment to be used to capture topographic details.
● Setting out techniques.
● Use of free station, reference lines, stakeout, tie distances within a total station program.
● Techniques to obtain setting out data, including data transfer.
● Process of setting out structures and offsetting lines of structural elements.
● Errors in surveying and setting out.
● Instrumentation error: prism constants, reflector heights, atmospheric influences, calibration certification, free station errors, discrete setting out.
● Human errors: alignment of levelling staffs and hand- or tripod-mounted prisms, physical setting out constraints.
● Comparing the accuracy of set out element to nationally recognised standards.

Surveying and Setting Out

Demonstrate the ability to undertake a topographic survey Illustrate the methods of application

Demonstrate the ability to establish a station network for horizontal and vertical control. Illustrate the methods of application, booking and calculation.

Evaluate the causes of errors and techniques to improve accuracy, including the use of digital data.

Apply industry-standard techniques in the production, transferring and staking out of co-ordinates of multiple construction elements. Illustrate the methods of application and transferring data to total stations.
