Week 71, Day 3:

• The day started early with another air pressure test which measured a result of 0.86 ACH @ 50 pa – compared to 0.92 at the previous test 9 weeks ago
  • So going the right way but the remedial work under the balcony didn’t have the dramatic effect the build team were hoping for
  • For reference, this equates to a hole of area 0.25 sq cm per sq m of area (and the area is 660 sq m) so that’s 165 sq cm, or an area roughly 13 cm x 13 cm
• A bit more work on the stone cladding, though without the two extra tilers helping out
