• Name five (5) examples of structural members or components in the project, describe the forces acting on the component and provide a diagram showing the load path in each component,

Structural members: A building maintains its shape, functionality and quality using its structure to withstand the forces, loads and other environmental factors that it is subjected to.

The study of structures involves the analysis of the forces and stresses occurring within a structure and the design of suitable components to cater for such forces and stresses. It also involves identifying and understanding loads and load paths or how the loads in the structure are transferred to the ground.

Examples of commercial building structural members include:

• reinforced concrete retaining walls and footings, slabs, columns and beams;
• masonry walls and columns.
• steel beams, columns, roof trusses and space frames.
• timber joists, columns, glulam beams and roof trusses.
• Bracings control excessive forces such as wind load and wave actions.

• Provide five (5) examples of safety measures by the Builder in relation to construction of the structural members/components.

Safety measures:

• Providing and maintaining safe plant and systems of work
• Arranging safe systems of work when working with plant and substances
• Providing a safe work environment
• Providing adequate welfare facilities
• Providing adequate information on hazards, as well as instruction, training, and supervision to employees, to enable them to work safely and without risks to health
