Armofer repeats the lowering procedure to deal with Group 2. The heart of the operation, once the boiler house area has been opened, is the lowering of the boiler by progressive cycles from its 53 m to the ground.

Once the structure has been divided into two parts, boiler and economiser, one and the other is lowered alternately. Deconstruction then takes place from below, with hot cutting and mechanical demolition with UHD excavators of portions of approximately 15 m. The cycle is repeated until the abseiling is completed.
