Floor by Floor Decostruction is a method used on structures that have come to the end of there useful life. Building such as Tower blocks which are too big to demolish by High reach demolition, or are situated too close to other structures or for Explosive demolition (Blow down) techniques to be used, are deconstructed floor by floor. The lifts are removed and the lift shaft blocked off at each floor after the soft strip material is sent down the hole as it is used as large rubbish chute, the pit being filled and the doorway opened up at the bottom to remove the rubbish.
