Elements and Performance Criteria

Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.
Specifications must include at least one of the following:	industry-accepted standards and specifications local government design standards and specifications state government design standards and specifications.

Appropriate persons must include at least one of the following:	client colleague engineer registered or qualified surveyor manager.

Design type must include at least one of the following:	railway rural road sewer line stormwater drainage line urban road other basic engineering structure.

Drawing functions and features must include at least eight of the following:	batters chainages dimensions drawing features, such as polylines and texts drawing functions edit functions horizontal and vertical alignments isometrics and perspectives longitudinal sections and cross sections macros methods for drawing lines plotting and printing plotting in two dimensions (2-D) super elevation using attributes to make project report using geospatial techniques vertical curves view displays volumes working with layers three-dimensional (3-D) techniques, including displaying 3-D views.

Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit. The person must also prepare a design and drawings for two projects using a basic engineering structure from one of the following categories:

stormwater drainage line

other basic engineering structure.

While designing the above basic engineering structures and creating related drawings, the person must:

communicate clearly with others to clarify and report project information

comply with organisational and legislative requirements for:

identifying hazards and working safely, using personal protective equipment (PPE)

recording, storing and filing data

reporting and completing documentation

setting up and using surveying equipment

comply with manufacturer specifications when calibrating and using equipment

create designs for basic engineering structures which include:

construction layout

cul de sac design

long section plots

natural surface cross-section

natural surface terrain model

vertical alignment design

create drawings that comply with design requirements, including:

data extracted from existing engineering drawings

drawing entities that are linked to database attributes

producing drawings, views and plots at required scale

create, extract and output information from engineering plans

organise resources and equipment appropriate to perform required work tasks

perform advanced data reduction techniques to reduce and manipulate surveying data

perform calculations appropriate to the type of engineering structure within industry-accepted tolerances for accuracy

plan work tasks by checking plans, drawings, maps and specifications

prepare the drawing environment by setting up the hardware and software system, drawing defaults and customising menus

measure components and design specifications within industry-accepted tolerances for accuracy and using two of the following pieces of equipment:

hand-held laser measuring device

global navigation satellite system (GNSS)

save drawing files in a range of formats relating to the design software, including one of the following:

data exchange format (DXF)

format used in triangulation process to define position of points and triangles (PTS)

Excel spreadsheet format (XLS)
