MODULE TITLE                  Building Site Surveying and Set Out 2


Nominal duration                   45-50 hours


Module codes

            DETAFE(SA)             CDCM

            National                      ABC084


Discipline code                       1004105


Module purpose                     To extend the students knowledge of basic measuring and levelling techniques to include instruments, procedures and calculations necessary in the set out and control of large residential developments, commercial and industrial construction.


Relationship to competency standards

                                                No Competency Standards are currently available


Prerequisites                          Building Site Surveying and Set Out l


Summary of content               The basic operation, testing and maintenance of a theodolite.

The use of theodolites for measuring and setting out horizontal and vertical angles.

Surveying instruments and techniques of particular benefit to large building projects.

Applications and calculations of co-ordinate and grid systems in building site set out.

Land titles and restrictions on land usage and the statutory responsibilities of builders and surveyors regarding boundaries and building mark outs.


Delivery                                  This module contains learning outcomes that will require both theory and practical instruction. Theory and tutorials should take place in a classroom or similarly appropriate area. The "practical" sessions will require a reasonably flat area of open space of sufficient size to accommodate the necessary field instruction/assessment.


Conditions                              Normally learning will take place in a classroom and as part of a field day exercise.


Assessment method               Written answers

                                                Short answers

                                                Practical field day test


Learning outcomes                On completion of this module the learner will be able to:


Learning outcome 1               Describe the basic components of a theodolite and how it should be tested for good adjustment.


Assessment criteria               1.1 Describe the various components of a theodolite.

1.2 Perform basic tests on a theodolite for accuracy and good adjustment.

1.3 State observing procedures which eliminate or minimise the effects of maladjustment in a theodolite.


Learning outcome 2               Set up and use a theodolite to determine horizontal and vertical angles.


Assessment criteria               2.1 Carry out the temporary adjustments to "set up" a theodolite ready for use.

2.2 Use a theodolite to determine (read) both horizontal and vertical angles to an accuracy of 20".

2.3 Use a theodolite to set out horizontal angles to an accuracy of 20".

2.4 Mark out a typical residential building using a theodolite and tape.


Learning outcome 3               Identify specialised equipment available for use on high rise and/or large building projects and illustrate how it can be used for various set out and checking procedures.


Assessment criteria               3.1 Differentiate between the various types of specialised surveying equipment available today. State its main use on a building site and basic method of operation.

3.2 Describe how equipment such as lasers, optical plummets, theodolites and EDM instruments can be used to control set out and verticality on multistorey buildings.

3.3 Outline the basic differences in survey control and set out between a steel framed and concrete multistorey building.

3.4 Carry out a survey of each floor of a building of at least five levels checking for vertically (accuracy of 10mm) using lasers, theodolites and plumbing equipment.


Learning outcome 4               Compute co-ordinates and bearings and distances as related to grids and general set out work on large building sites.


Assessment criteria               4.1 Demonstrate the angular relationship between different bearings (whole circle) and determine bearings from angles and fixed lines.

4.2 Calculate the bearing and distance between two sets of co-ordinates (north and east).

4.3 Calculate the co-ordinates of a point given the bearing and distance from a point with known coordinates.

4.4 Determine offsets from a co-ordinated point given the bearing and distance from a point with known co-ordinates.

4.5 Calculate the information necessary to set out a structure, or part thereof, using a site plan with positions fixed by a mixture of bearings and distances, offsets and co-ordinates.


Learning outcome 5               Identify and discuss the various documents and plans incorporated in land titles.


Assessment criteria               5.1 List the documents which make up a land title and discuss their relationship to each other.

5.2 Illustrate how different restrictions on the use of land, as shown on the title, can restrict development.

5.3 Discuss building covenants and the statutory

bodies responsible for them.

5.4 Identify and differentiate between the various restrictions stated in acts of parliament, and codes, which regulate set backs for residential buildings.
