The birdcage scaffold is an independent scaffold that consists of more than 2 rows of standards in either direction that are connected by transoms and ledgers.
It is primarily used for work that’s done on a single level such as ceilings.
It is important to consult the manufacturer’s or designer’s specifications when you erect or dismantle a birdcage scaffold made from modular scaffolding.
You should implement the risk control measures below for birdcage scaffolding that’s made from tube and coupler scaffolding.
– The birdcage scaffold should only be used for supporting formwork if it is designed specifically for this purpose.
– You should provide transverse bracing at each forth bay on the scaffolds ends.
– You should brace the outer row of standards on either face as well as each third row internally using longitudinal bracing.
– You should provide a tied face or longitudinal bracing at every third longitudinal row of standards.
– To help with the erection or dismantling of birdcage scaffolds, you should consider using elevated work platforms.
A fall arrest system is usually not the ideal risk control measure when erecting or dismantling birdcage and perimeter scaffolds.
Refer to the general guide of scaffolding work and scaffolds for additional information on fall arrest systems.
