Outcome sought: To Make Block A Weather Tight

o Overview of the programme:
o Claddings Plywood claddings at the south elevation stairwell, east elevation fire panel and internal corner and north elevation classroom have failed due to a combination of inadequate diverter flashings, paving clearances and cladding overhangs, lack of capillary
gap and priming, and poor preservative treatment typical of the installation period, resulting in timber decay
o A lack of clearance at the external stairs on the west elevation has trapped water against the cladding, resulting in moisture absorption and timber decay
o Leaking has occurred at the unsealed bridge west elevation joinery perimeters, resulting in decayed sill reveal liners
o Conduits have trapped water against the cladding at the stairwell west elevation, resulting in decayed plywood cladding
o It is recommended the above elevations are reclad. The Ministry may wish to consider replacing the existing window and door joinery on these elevations with new double-glazed units which may be more cost-effective than refurbishment and reinstatement.
Leaking has been confirmed at the bridge west elevation joinery perimeters (as noted above).
o There are similar risks on the bridge east elevation
o Recladding the bridge east elevation in conjunction with the adjacent recladding of the stairwell south elevation. There are currently patches on the staffroom north elevation cladding where DT investigation was previously undertaken
o It is recommended the affected cladding panels are replaced in line with Ministry policy.
