There are two buildings One Tree Hill College, Penrose, Auckland with weathertightness problems: Block AL (Administration Knowledge Centre) and Block PAC (Music Suite). Both buildings are located at the front entrance to the school.
The weathertightness failures and consequential damage identified in a Remediation Inspection report, and that the Ministry has decided to address, are summarised as follows:
Block AL:
• Roof Parapet - Reclad fibre cement cladding and associated flashings to parapet wall. These works form part of the recladding works recommended for the East wall face.
• East elevation and parapet above - Part south face above flat roof. Reclad wall faces where cracked and misaligned cladding, damaged substrates and associated flashings where damaged or missing. Remove, refurbish and reinstall affected external joinery.
• East wall - Base of wall to be reformed to allow the installation of a vermin control strip as part of the reclad works to the east wall.
• West elevation - An alternative solution is offered to the recommended solution to renew joinery and provide effective perimeter flashing to restricted wall opening including a 20mm max sill upstand. A new porch roof is proposed to shelter this exposed doorway. The door threshold sits hard down on a structural concrete beam and to raise the sill further may present a tripping hazard at this fire exit. The proposed porch has been designed without further penetrations to the Music Suite metal roof below and relies on the existing steel landing structure and the roof fascia above.
Block H:
• East and West walls - replace fibre cement wall cladding with new cladding on timber battens and RAB on existing framing.
• North elevation: Replace interior linings to North elevation at low level below windows to allow installation of air seals. Replace or reinstate linings and architraves. One central teaching space requires removal and reinstatement of full-length trunking below the windowsill.
