The document discusses formwork, which is material used to support concrete structures and mold them into shape. It describes the main materials used for formwork as steel, wood, and aluminum. The presentation then covers considerations for good formwork like being water tight and reusable. It provides details on the advantages and disadvantages of steel and aluminum formwork, including their suitability for different projects. Cost ranges of $100-300/sqm for steel and $99-145/sqm for aluminum formwork are given.

2. WHAT IS
FORMWORK ?
- Supports structure and molds to create structures out of concrete
- Made by using steel, wood, aluminum and prefabricated forms
- Cost of formwork is around 30-40% of the concrete cost

METAL
FORMWORKADVANTA
GESSTEEL ALUMINIUM
Stronger, durable and longer life than timber
formwork
Often used in pre-fabricated formwork
Can be reused many times Strong and light in weight
Can be installed and dismantled with greater ease
and speed
The lighter sections will deflect more
Quality of exposed concrete surface is good Can be recycled after smelting
Does not absorb moisture from concrete Highly precise in assembly
Does not shrink or warp Can be reused for more than 300 times

7. SUITABILITY
STEEL ALUMINIUM
- Widely used in large projects or in situation where
large number reuses of the shuttering is possible
- Suitable for low as well as high rise building
- For heavy concrete work - can be designed for any condition/component of
building such as bay windows, stairs
- Suitable for circular or curved shaped structures
- such as tanks,
columns, chimneys.
- Bridge construction / Airport construction
