RTB eLearning

This module describes the knowledge, skills, and attitude to be acquired to perform reinforced steel bars works as well as performing all steps involved in making steel bars framework on the site. It is intended to be pursued by the learner at TVET level IV in building construction. At the end of this module, the learner will be able to select tools, equipment and materials to be used for steel bar works, interpret steel bars drawings, calculate cutting length, cut steel bars, bend steel bars and tie steel bars.

Course Summary: Reinforcement Steel Bars Works

This course introduces learners to the principles, techniques, and practices of working with reinforcement steel bars (rebar) used in reinforced concrete construction. It covers the identification, selection, cutting, bending, placing, and tying of reinforcement steel according to construction drawings and specifications. Emphasis is placed on ensuring structural strength, durability, and safety of reinforced concrete elements such as beams, slabs, columns, and foundations.

The module also highlights standard codes of practice, tools and equipment for reinforcement work, safety measures, and quality control in reinforcement placement. Learners gain both theoretical knowledge and hands-on skills required in the preparation and installation of reinforcement steel in building and civil engineering projects.

By the end of this course, learners will be able to:

• Understand the role of reinforcement steel in concrete structures.

• Identify types, grades, and sizes of reinforcement bars.

• Interpret reinforcement detailing from construction drawings.

• Cut, bend, and tie reinforcement bars to required shapes and dimensions.

• Place and secure reinforcement in formwork according to standards.

• Apply safety and quality control measures during reinforcement works.

Rolling is a metal forming process in which a metal workpiece is passed through one or more pairs of rotating rollers to reduce its thickness and improve its shape and surface finish.

It can be performed hot (above the metal’s recrystallization temperature) or cold (below it). Hot rolling improves ductility, while cold rolling increases strength and surface quality. Rolling is widely used to produce sheets, plates, bars, and structural shapes in manufacturing.

This module describes skills, knowledge and attitudes required to construct a roof structure. It is meant for learners who have successfully completed level IV in building construction and pursuing level V in building construction. At the end of this module students will be able to Perform roof preliminary works, set out the roof, fix roof and apply roof coverings with minimum supervision.

Course Summary: Scaffolding Operations

The Scaffolding Operations course equips learners with the knowledge, skills, and attitudes required to safely plan, erect, use, inspect, and dismantle scaffolding structures at construction sites. The course emphasizes compliance with safety regulations, proper selection of materials, risk assessment, and teamwork in scaffolding tasks.

Learners will be introduced to different types of scaffolds, their components, and methods of assembly and disassembly. Special attention is given to accident prevention, load management, hazard identification, and safe working practices when working at heights. Practical sessions allow learners to gain hands-on experience in using scaffolding tools, equipment, and protective gear.

By the end of the course, participants will be able to:

• Interpret scaffolding drawings and specifications.

• Select appropriate materials, tools, and equipment for scaffolding tasks.

• Safely erect, maintain, and dismantle scaffolding structures.

• Conduct routine checks and inspections for stability and safety.

• Apply occupational health and safety measures in scaffolding operations.

This course is designed for construction workers, site supervisors, and trainees who aim to build competence in scaffolding as part of broader construction operations.
