The Internal birdcage scaffolding module calculates tube and fitting birdcage scaffolding, in internal locations not exposed to the wind, in accordance with BS EN 12811 and TG20:21.
The software checks whether the scaffold is TG20:21 compliant, calculates the maximum leg loads for foundation design and, if the scaffold is tied, the maximum tie duty and required tie pattern.
