Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

None

Course Description

This unit covers the competency to use levels, theodolites and distance measuring techniques to perform basic measurement and layout tasks on construction sites. The intent is for people carrying out design and/or drafting activities to communicate effectively with surveying personnel and to understand survey data that they use to produce designs and drawings.


National Codes, Titles, Elements and Performance Criteria

National Element Code & Title:

EDC040 Perform measurements required in the construction of rural roads

Element:

Calculate volumes from spot heights

Performance Criteria:

1.1 The volume to datum form spot heights derived form grid levelling can be calculated.

Element:

Carry out correct layouts

Performance Criteria:

2.1 Levels in a closed traverse can be observed to third order precision.
2.2 Levels can be reduced in a closed traverse using the rise and fall method as well as the collimation height method.
2.3 Levelling observations can be performed incorporating intermediate sights and inverted staff reductions.
2.4 Reduction procedures can be completed for both methods showing all mathematical checks.
2.5 Levels can be transferred in multi-storey buildings.

Element:

Determine bearings for the sides in a traverse

Performance Criteria:

3.1 The theodolite is set up over a ground mark allowing for any bubble error.
3.2 The repetition method is used to observe horizontal angles in a traverse and the measured angles are reduced.
3.3 The angular misclosure in a closed traverse is calculated and the adjusted angle calculated.
3.4 Vertical angles are observed and reduced.

Element:

Observe short distances to industry standards for engineering surveys

Performance Criteria:

4.1 The major sources of error in distance measuring operations can be identified.
4.2 A band or tape is used to measure distances of up to 100m to engineering survey accuracy.
4.3 The reduced horizontal distance is calculated for taped lines allowing for temperature, tension, sag and slope corrections.
4.4 EDM can be used to measure the distance of a line previously measured by tape or band and the results compared and reported.

Element:

Perform detail surveys using the grid levelling method

Performance Criteria:

5.1 The grid is laid out at a specified interval over a given area.
5.2 Levels are observed on the grid points to obtain spot heights for contouring.
5.3 A contour plan can be produced from the spot heights derived from grid levelling.

Element:

Perform levelling traverse procedures

Performance Criteria:

6.1 The terms Australian Height Datum, level surface and horizontal surface can be explained.
6.2 The major types of levels used in industry can be named.
6.3 The construction features of levels can be described.
6.4 The horizontal collimation error of a level can be determined using the two peg test.
6.5 The adjustment procedures for the main types of level can be outlined.
6.6 The main sources of error in levelling operations can be identified.
6.7 Levels are observed in a closed traverse to third order precision.
6.8 Levels are reduced in a closed traverse using the raise and fall method and the collimation height method.
6.9 Levelling observations are performed incorporating intermediate sight and inverted staff readings.
6.10 Reduction procedures for both methods are completed.
6.11 All mathematical checks are shown.
6.12 Levels are traversed in multi-story buildings.

Element:

Perform simple detail surveys using theodolite and tape

Performance Criteria:

7.1 Detail surveys are performed by distance and offset measurements along a baseline.

Element:

Produce and interpret simple site plans

Performance Criteria:

8.1 A site plan can be plotted from distance and offset measurements along a baseline.

Element:

Set out works using simple site plans

Performance Criteria:

9.1 A site plan can be used to set out works by distance and offset measurements along a baseline.
