This guide provides assistance for building designers undertaking the design of weathertightness remediation solutions. It focuses on design aspects particular to weathertightness remediation rather than the usual design process.
It is primarily targeted at designers who are either already undertaking this type of design work or, are considering taking it up. BCAs, builders and homeowners may also find the information useful.
The guide is primarily written to cover buildings:
• within the scope of NZS 3604 Timber framed buildings
• typically built within the period 1993–2004 that have timber framing with either reduced treatment levels or no treatment and therefore are more susceptible to timber decay if the building leaks
•typically built with direct-fixed monolithic cladding.
However, the processes outlined in this guide will be applicable for most buildings requiring weathertightness remediation.
