The Occupational Health and Safety (OHS) Level 3 course equips learners with the knowledge, skills, and attitudes required to maintain a safe and healthy work environment. It focuses on identifying workplace hazards, assessing and controlling risks, following safe work procedures, and complying with relevant legislation. This course is suitable for individuals working in technical, industrial, construction, and service sectors who are responsible for ensuring their own safety and that of others in the workplace.
Course Outline: Produce a Computer-Aided Project Drawing
Domain: Building and Civil Management
Level: 4
Credits: 5
Duration: 5–6 Days (40 hours recommended)
Target Group: Trainee carpenters, plumbers, bricklayer apprentices, or artisans seeking to develop technical drawing skills using CAD
Prerequisite: Unit 1157 – Demonstrate basic knowledge of workplace health and safety (or equivalent)
Course Purpose
To equip students with the competencies required to produce computer-aided drawings for building and construction projects. This includes planning and preparing, identifying objects to be drawn, establishing drawing criteria, using CAD software, and producing verified hard copies.
Learning Outcomes
By the end of this course, learners will be able to:
-
Apply safety and environmental standards in a CAD workspace.

Identify carpentry-related components to be drawn.
-
Establish appropriate drawing criteria, dimensions, and specifications.
-
Create computer-aided drawings from the line and detail stages.
-
Draft, verify, and print final drawings using industry-recognised standards.
