This course describes employable and practicable skills; knowledge and right attitudes required by a learner to prepare materials, tools and equipment, carry out aluminum with its alloys temperature casting process and perform post- casting activities.

This module describes the skills, knowledge and attitudes required to perform basic domestic electricity. It is intended to be pursued by learners at TVET Certificate III in building construction. At the end of this module, the learner will be able to select tools, materials, PPE and equipment, apply basic domestic installation and perform testing of installed circuits. The learner deemed competent to this module may work at construction site in basic domestic electrical installation stage under minimum supervision.

This specific module describes the skills, knowledge and attitude to perform reinforced concrete works on construction site. It is intended to be pursued by learner at TVET level V for TVET Certificate IV in Building Construction. At the end of this module, the learner will be able to: Interpret structural details, identify structural members’ connections, determine forces acting on structural members and design concrete structure elements

Casting Process is a process in which hot liquid metal is poured into a mould that contains a hollow cut out or cavity of the desired finished shape. it is begins by creating a mould, which is the ‘reverse’ shape of the part we need. The mould is made from a refractory material, for example, sand. The metal is heated in an oven until it melts, and the molten metal is poured into the mould cavity. The liquid takes the shape of cavity, which is the shape of the part. It is cooled until it solidifies. Finally, the solidified metal part is removed from the mould.

Basics of Hydraulic System

• Definition: A hydraulic system is a power transmission system that uses pressurized liquid (usually oil) to transmit force and motion.

• Principle: It works on Pascal’s Law, which states that pressure applied at one point of an enclosed fluid is transmitted equally in all directions.

• Main Components:

  • Hydraulic pump (converts mechanical power into fluid power)

  • Valves (control pressure, flow, and direction)

  • Actuators (cylinders or motors that convert fluid power into mechanical motion)

  • Hydraulic fluid (medium for power transmission and lubrication)

• Applications: Heavy machinery (excavators, presses), automotive brakes, aircraft systems.

• Advantages: High force output, precise control, smooth operation.

Basics of Pneumatic System

• Definition: A pneumatic system is a power transmission system that uses compressed air or gas to transmit and control energy.

• Principle: It works on the compression and expansion of air; force is generated by pressurized air acting on a piston or actuator.

• Main Components:

  • Compressor (supplies compressed air)

  • Valves (control air pressure, flow, and direction)

  • Actuators (pneumatic cylinders, air motors)

  • Air treatment units (filters, regulators, lubricators)

• Applications: Automation in industries, packaging machines, air brakes, dental tools.

• Advantages: Clean, lightweight, safe in hazardous environments, simple design.

This module describes the knowledge, skills and attitude required to create highly precise 2D designs that visualize construction drawings. It is intended to be delivered to learners pursuing TVET level IV in building construction. At the end of this module, the learner will be able to create, modify and plot construction drawings.
