No construction project can be initiated without proper scaffolding. Before completing the final structure, it is integral for construction workers to be able to reach heights, support their tools and load/unload heavy equipment. These cannot be possible without proper scaffolding. Usually, timber or wood is employed to make them, and they vary with the type of construction going on. Using the right scaffolding system is vital for any construction to be done properly and it also ensures the safety of workers.
We have compiled a list of the most common scaffolding techniques used in construction.
- Wooden and bamboo scaffolding.
This is most commonly seen in countries of Asia, South America and Africa, since timber and bamboo are naturally found in abundance. Almost all structures in these countries, ranging from single-storey houses to skyscrapers, are built using this technique. It is considered to be one of the oldest methods of scaffolding and remains popular in many parts of the world.
- Trestle scaffolding.
In this type of scaffolding, the working structures are supported by using tripod style movable ladders. It reaches a height of 5 metres only, hence this is mostly used for indoor services like paint jobs and repair work.
- Kwikstage scaffolding.
This type of scaffolding is most common in parts of Australia and UK, for both commercial and residential structures. This is made from hardwearing galvanised steel and is very easy to install as well as disintegrate. It can be customised to suit both outdoor and indoor work, hence it is provides a safer and more durable platform to work on.
- Single scaffolding.
This is one of the oldest methods of scaffolding, mainly used for brick masonry. This incorporated the use of ledgers, putlogs and standards which are set up about 1.2-1.5 metres from the wall. This requires very accurate technical measurements.
- Double scaffolding.
Another commonly used scaffolding technique; this is used mainly for stone masonry and is also known as independent scaffolding. Since it is difficult to drill holes into stone walls, two structures on top of each other provide better support. The first row is erected 30 cm from the wall and the second is about 1-1.5 metres away from the first row.
- Cantilever scaffolding.
This is a job-oriented scaffolding which does not work for all structures. In this, chains of needles sticking out from the wall support the standards. This is called single frame scaffolding.
In double frame scaffolding, the floor supports the needles instead of the walls. It is advised to be cautious while working with this setup. Generally, this has limited applications and is only used when the upper wall is used for construction, the ground is unstable to support scaffolding or the structure is too close to traffic.
- Steel scaffolding.
This type of scaffolding has numerous applications and is very easy to construct and disintegrate. Steel tubes are fixed together using steel couplers and fittings. This is resistant to wear and tear and provides the most safety to workers; hence this is extensively used despite its expensive nature.
