The Futurist, Scarborough Demolition sequence Following the reduce level dig to the upper plateau on Kings Street and installation of the mass concrete ballast, we will commence ‘ of r p' to full internals of the structure with skips placed outside the main entrance for debris removal. Mechanical demolition will then commence to phase 1 working in from the north east corner using a specialist D-Rig Hy reach excavator with demolition attachments. When phase 1 is complete the high reach can remove the flat roof section of Phase 2 and then proceed to the front wall reducing it to first floor height . A scaffold platform will be built off the roof steel work to facilitate the removal of the asbestos roof sheets to the theatre.. When the roof sheets have been removed the trusses will be removed using a cherry picker, Hy-reach excavator and cutting tools to safely lower the trusses to the ground. Following the truss removal the outer walls to phase 3 and 4 will be taken down to first floor level this is where the transitional steel beam spanning the seating is located, the exactor will be used to remove the seating tier to level one removing all timbers and secondary steels to the seating level, once this is complete the walls will be reduced to allow a crane to access site and lift the main beam down to grade allowing it to be cut to size and removed from site. The same process will now be utilised to bring phase 5 and 6 to grade starting from the façade once again employing the crane to remove the 2 main steels spanning the seating section. All scaffold will then be removed from site and the remaining walls folded into the footprint of the structure, the crusher will be delivered to site to crush the material to 6F2 and stockpiled on site. Slabs and footings will be broken and also crushed to 6F2 and material re- laid to ensure no leading-edge hazards remain. All wastes will be removed form site at regular intervals and dust will be suppressed via the use of 2 Dust Cannons one at the rear and one on the working face of the demolition..
