      Crack, approximately 60mm long x 1mm wide, developed in the central area of the exposed face



      Issue of smoke increased



      Top edge of wall moved outwards a further 5mm



      Top edge of wall moved outwards to a total of approximately 36mm



      Top edge of wall moved outwards to a total of approximately 44mm



      Gap, up to 10mm wide, developed between centre of top of wall and lintel due to the top edge of the wall bowing downwards



      Top edge of wall moved outwards to a total of approximately 65mm
