7No 1.30m wide windows were formed in 260mm RC walls but a change of design meant the sill height had to be reduced by approx 300mm.
Using a combination of diamond track sawing, diamond stitch drilling and concrete crunching the sections were removed.
Each section was overcut by 30mm to allow for a repair mortar to be placed to give a protective finish – this work was also carried out by Invictacut.
