Before starting with the actual Learning Project, please familiarise yourself with the information on this page!
How to use this workbookThe DSPP learning support material provides additional teaching aids for the knowledge and practical skills modules based on the NOCC-A21 syllabus that was developed according to the new QCTO curriculum. The workbooks supplement the existing learning material available at the TVET colleges and consist of work assignments, which can be used by the lecturers as part of the assessments. The completed assessments will be filed in the Portfolio of Evidence (PoE) and form one of the admission requirements for the trade test at the end of the apprenticeship.
The workbooks focus on practical, workplace-driven aspects and contribute to personal growth and development of the apprentice. The focus is the apprentice!
The workbooks are arranged under headings (viz. Introduction to the Learning Project, Preparation, Theory, Work Assignments and Assessments, Further Development and Workplace Experience), using colours and icons to help the apprentice navigate easily through the workbook and are designed to suit the level of the apprentice. The mentioned time allocation is applicable to the knowledge and practical modules done at the TVET college only.
Below is a short description of the different sections of the workbook.
Introduction to the Learning ProjectOn page 4 of the workbook, the apprentice is introduced to the Learning Project. The section begins with a motivational quote, picture or story to inspire the apprentice to 'think out of the box' and to apply this mind-set to work with the workbook. With a short paragraph introducing the upcoming Learning Project, the apprentice will have an idea of how the practicals will be applied in class.
PreparationThe next heading "Preparation" is one of the most important parts of the workbook and can be used at the beginning of the Learning Project. The aim is to arouse the interest of the apprentices in the Learning Project by challenging them with problems and questions varying in difficulty and presented in a fun, creative and mostly scenario-based fashion. There is no pressure on the apprentices to have all the answers - this will encourage them to participate.
TheoryThe theoretical section entails the formal process of instruction as set out by the NOCC-A21. The lecturer is aware as to the desired outcomes and range of topics and he/she plans the process in such a way that training is effective and completed within the allocated time frame.
Work Assignments & AssessmentsWork assignments are completed by apprentices in order to assess their knowledge and skills and to determine effectiveness of the training against the stated outcomes. The assessments and evaluations are done objectively and present an opportunity to identify and schedule remedial activities. These must be formally agreed upon between the apprentice and the lecturer. Furthermore, the assessments serve as proof for the completed knowledge and practical skills modules in the Portfolio of Evidence (PoE).
Further Development & Workplace Experience"Further Development" aims to allow apprentices to delve deeper into the featured topics. The format may include references to websites, books, documents, projects or experiments. Lecturers do not formally keep track of apprentices’ activities in this section. The employment of the apprentices at the workplace is aimed to provide “real-life” work experience. The "Workplace Experience" section of the workbook ensures that apprentices complete a variety of tasks at the workplace.

My progress in becoming aProfessional Plumber
Do you understand how much potential you have; what life you are capable of?
1. Introduction to Learning Project 2Plans, technical drawings visually communicate how something functions or is to be constructed. It is essential for communicating ideas in industry and engineering. To make the drawings easier to understand, familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layouts are used. Together, this constitutes a visual language, and helps to ensure that the drawing is clear and relatively easy to understand.
It is necessary for you to understand the trade-specific vocabulary and principles of communication within this context. In this learning project you will learn the basics for you to be able to communicate in a professional manner with all relevant role-players.

Interesting Facts on Paper Sheet Sizes
Metric format
• The formats are based on the metric measurement system. The area of the format A0 is equal to the metric area unit of 1 m².
AA0 = Width x Length = 841 mm x 1189 mm = 0,841 m x 1,189 m = 1 m²
• �The�ratio�between�the�length�and�the�width�equals�the�ratio�of�the�side�of�a�square�to�the�diagonal�of�a�square.
Width�:�Length�=�1�:�√2

Work Assignment 1
ScenarioYour colleagues are currently busy with the plumbing installation of a free-standing family home in a lifestyle estate. In the evening they bring back the various plans to ask for some clarification. They have marked the different sections of the plan and want to know what the main purpose of each section is (see Annexure A).
Task 1.1
Discuss the section given to your group and present your findings to the class. Pay attention to the following:
1. Has the section been drawn using the relevant standard?
2. Which parts of the information is relevant to you as the plumber?
3. Is information missing? If yes, which information would you need?

Work Assignment 2
ScenarioThe next morning, the project leader calls the secretary and informs her that he will be off duty for the next 3 weeks due to a sports injury he suffered the previous evening. Your boss asks you to stand in for the project leader and hands you the drawing (Annexure A) to familiarise yourself with the situation.
Task Study the drawing (Annexure A)and answer the following questions.
2.1
You were told that plans of this type were valid for a period of two years after being approved.
Has this plan (i) been approved, and (ii) is it still valid?
2.2
Arriving on-site, the client awaits you with some questions. As he is planning to install a photovoltaic system, he wants to know how far (in degrees) the house is orientated from North.
Explain how you can determine the exact orientation by only using the plan, a pen and a ruler.

2.4
After you have answered the client's question regarding the orientation of the house, you analyse the work that has been completed so far and assess what needs to be done next.
Your colleagues are currently digging the trench for the drainage section 1.
John, one of your workers always wants to know exactly how deep he has to dig in order to not waste time and energy.
Make a small sketch (top view and side elevation) for John and include the following information:
• Depth at the beginning of the trench [m]
• Depth at the end of the trench [dm]
• Fall of the drainage pipe [%]
• Width of the trench [mm]
