Assignment - Linear survey and levels

Introduction
Surveying techniques are of concern to many built environment practitioners - either for recording existing topographical and built features or for setting out new work. This module offers you a combination of theory based and practical fieldwork to develop a sound knowledge of the essential surveying procedures and recording protocols, linking traditional manual techniques to applications, so that you can feel confident in the modern workplace. The relevant mathematical skills will be introduced and developed contextually. Final survey drawings will be produced and annotated and you will carry out simple setting out activities using industry best practice.

The present assessment sheet covers the following learning outcomes:

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 minimize the errors.

Thus, students will be given a specific set of customer requirements and appropriate actions should be taken in order to carry out the procedure of Topographical Survey of a project that covers the given requirements. At the end, a Technical Report has to be given in order to describe the actions that have been taken in order to overcome the intermediate stages of Topographical Survey. Also, detailed Topographical Drawings will be included at the Technical Report. Get reliable and affordable assignment help today!

Engineering Design Scenario and Customer Requirements:

The Ministry of Energy Environment and Climate Change asked from Mediterranean College to be their Technical Consultant in a big project of the re-construction of the College's surrounded area. Before any preliminary design or calculations carried out, a scaled drawing of the area is required, which must include level information (key spot levels) as well. As this drawing is required for the feasibility stage (i.e. start of the development of a project), and the surrounded area of the college is not large, it would be practical and economical to carry out this survey using linear surveying techniques.

You have to make a preliminary hand drawing (crocki) of the area that the government want to survey.
Choose the appropriate control stations, from which the main topographic features will be surveyed (building corners, trees, paved areas, footpaths, etc) and record the main dimensions between the stations.

Detail points will then be surveyed from the main control stations, using the standard booking system to produce clear and precise sketches. You have to set a local coordinate system. Set coordinates of your first control station as (1000m, 2000m,10m) and then using the above control stations make a close type traverse so to find all the rest coordinates and levels.
Finally, make a contour map in AutoCAD file (.dwg) of the chosen area.

Calculations should be followed by a Technical report about 1500 - 1700 words in length, conforming to the appropriate assignment standards. It is recommended to divide the Technical report into sections by using titles and sub-titles and a robust conclusion. Reference sources can be freely drawn on. Additional supporting data (e.g. surveying record sheets, sketches, etc) should be included within your Appendices, but must be suitably explained and referenced in the main text.

Assessment Declarations for the Technical Report - Topics to be Covered:

Principles of linear measurement
Control stations, techniques for detail acquisition, slope and plan distances, standard recording techniques, accuracy and sources of error, corrections to measurements.

Principles of levelling
Types and use of levelling equipment, booking and reducing protocols (manual and spreadsheet), arithmetic checks, accuracy and sources of error, adjustments and corrections, contouring.

Angular Measurement
Types of theodolite, temporary adjustments, horizontal and vertical angular measurement, minimizing errors.

Recording and Presenting Information
Manual recording of survey data, spatial and dimensional interpretation of survey results, accuracy checks, presentation formats and conventions.

Surveying work will be completed in a maximum of one block (Traverse and levelling). The field works will be carried out in groups, the numerical data are universal, but all other work is to be independent.
