Practical Surveying Procedures and Recording Protocols Assessment

Question

This assessment is designed to give the student practical experience to develop a sound knowledge of the essential surveying procedures and recording protocols.  

On successful completion of the assignment, the student should be able to:-

1.Carry out a topographical survey using surveying instruments, record findings and use fieldwork data to produce a scaled survey drawing.

2.Accurately carry out levelling exercises.

3.Undertake simple setting-out exercises and discuss the accuracy achieved, the likely sources of errors and the steps taken to minimise the errors.

The Brief

You are invited to complete the associated tasks in the work book. Each task is designed to demonstrate your knowledge of surveying practice.

You need to show all working for calculations and explain the written work in a manner that justifies the processes and list out equipment etc…

Task 1 Linear survey 20%

Task 2 Levelling 25%

Task 3 Contouring 30%

Task 4 Angular mis-closure 15%

Task 5 Slope correction 10%

(with corresponding percentage of total assignment mark shown in brackets)

The assignment will be in report format, between 1250 and 1750 words in length, conforming to appropriate written assignment standards. Dividing the submission into sections by using sub-headings makes presentation and reading easier; and a robust conclusion (drawing on arguments presented in your writing) is a vital element.

Reference sources can be freely drawn on, but remember to cite the source(s) used, and identify them properly in the References section. Additional supporting data (e.g. surveying record sheets, sketches, etc) should be included within your Appendices, but must be suitably explained and referenced from the main text.

Submission Date

The assignment must be handed in to the Student Information Centre (Markeaton Street) on or before the date of submission.  Late submission risks being penalised.

Task 1

Describe how a chain survey is undertaken in the field.

Task 2

Table RC1 shows the field data collected for a level survey. From the information calculate the reduced levels and check the accuracy of the information.

Task 3

The levelling information is from a grid at 10.000 centres, plot this grid out with the reduced levels and determine the contours at every 0.500m plotting the results.

Task 4

A traverse is done of a building site and the information has been collected on table RC2. Check the survey and apply any corrections needed. Draw the closed traverse to scale by hand

Task 5

Using the measured lengths of the sides of the traverse and angular data calculate the plan lengths of the traverse.

For Pass the student will have plotted the survey data at a suitable scale and the drawing will be to a reasonable standard of presentation mostly using industry standard drawing techniques and symbols.  A list of equipment and an explanation of the sequence of work of operations will be provided. Some reference will be made to the surveying techniques used, the accuracy achieved and the possible sources of error that may have occurred within the work. Some mention will be made of the standard corrections to be applied. The student will reflect on the standard of work undertaken to meet the brief and suggest how an improvement could be made if the task was repeated. The presentation will demonstrate an attempt to satisfy conventions; references will be given and cited.

To Fail the student will not have submitted very few of the appropriate survey record sheets to a poor standard. The survey data will be inaccurately plotted at a suitable scale and the drawing will be to a poor standard of presentation not using industry standard drawing techniques and symbols.  A list of some of the equipment and a poor explanation of the sequence of work of operations will be provided. Poor reference will be made to the surveying techniques used, the accuracy achieved and the possible sources of error that may have occurred within the work. Conclusions will be inadequately supported, and the presentation will be lacking in clarity and not complying with written work conventions.
