A huge forest of scaffolding, fused by the fire in April, has to be cut away
The restoration of the cathedral of Notre Dame in Paris, which was badly damaged by fire on 15 April, has entered a new and delicate phase. This involves removing a vast and heavy scaffolding structure at roof level that became fused by the intense heat. It had been erected before the fire in order to carry out restoration work on the 19th-century roof spire, whose dramatic collapse was seen on screens around the world.
The removal of the scaffolding requires three levels of steel beams to be positioned around its exterior to form a stabilising “belt”. Once this operation is complete, the same firm that built the scaffolding (Europe Echafaudage) will start to dismantle it, using telescopic crawler cranes that will allow roped technicians to descend into the forest of pipes and gradually cut them away after having coated them with a protective layer to avoid spreading the pollution caused by the melting of the lead roof. Work is expected to be complete next April.
