1.2 Explain ONE advantage of galvanising.
Answer
One significant advantage of galvanising is that it provides excellent protection against corrosion. Galvanised steel, for example, has a zinc coating that acts as a barrier to moisture and other environmental elements, significantly extending the material's lifespan. This makes galvanised materials ideal for outdoor and industrial applications, where they are exposed to harsh weather conditions.
Step 3

1.4 Describe TWO methods that can be used to move building material around the site.
Answer
Two methods for moving building materials around a site include:
-
Forklifts: These are commonly used to lift and transport heavy materials, including pallets of bricks and concrete blocks, across the construction site quickly and safely.
-
Cranes: Large construction sites often employ cranes to move heavy materials vertically and horizontally. This allows for efficient placement of materials at various elevations, which is essential in multi-story construction.
