The holes for the doors and windows are being cut out by D-Drill Master Drillers Ltd, using a Diamond Wire Cutter.
Firstly 50mm holes are drilled in the corners of the proposed opening ready for feeding the wire through. Using a continuous length of diamond-studded wire, tensioned on a series of hydraulically operated pulleys the wire is fed through the holes and slices from inside to out.

Cutter in Action
The first cut was 1700mm deep by 1000mm wide and took about an hour to complete.
The pieces to come out will weigh up to 4 tons each so need to be cut down into “bite sized chunks” of up to 1 ton for removal.
