The document discusses renovations to the main dome of Vaux le Vicomte Castle in France. A scaffolding system without supports on the dome will be constructed using a 150 ton Layher scaffold and steel deck. A 19 meter footbridge will be assembled on the ground and lifted into place by crane to provide access. Diagrams show the scaffolding structure and fixation points on the wooden skeleton underneath the dome.
