the Building Envelope
Industry Best Practice Programmes
The Claddings Institute has focused much of its
recent time and energy on raising awareness of the weather-tightness
problems faced by the construction industry in New Zealand.
This has involved the organisation of a number of industry
forums and presentations, participating in a study tour to
North America and publishing a summary booklet on this tour,
on-going liaison with contacts established overseas, participation
in the Industry Weathertight Buildings Steering Group, preparation
of the proposed Industry Accreditation Scheme, providing input
and/or advice regarding correct procedures to follow.
With the BIA now undertaking an inquiry or overview
of the situation the focus of the Institute's activities can
move to the next stage - the facilitation of programmes to
help resolve the issues long-term.
From feedback received two programmes have been
identified to start this process. These are;
- Development of a Weather-tightness Best Practice
- Development of training courses focusing on
Weather-tightness Best Practice Guide
It is proposed that industry collectively produce
a guide that provides details of the principles of weather-tightness
and/or moisture management in relation to the building envelope.
All sectors of the industry involved with the building envelope
would prepare material on their particular sector, in consultation
with industry, for inclusion in the guide. This material would
be reviewed to ensure all aspects are consistent.
Material included in the guide will cover basic
principles and be generic in nature. It would not be feasible
to provide solutions for every situation or to cover proprietary
systems. The generic information provided should not be used
as solutions for proprietary systems. Specific design will
still be needed and proprietary system manufacturers will
need to supply standard details required for the installation
of their systems.
The guide will set out which details are considered
to be standard. Examples of such details will be included
together with the design principles. Manufacturers would be
expected to produce a similar set of standard details in their
literature. When non-standard details are required because
of the architecture, these would need to be specifically designed
and approved along similar principles.
Weather-tight Principles Training Course
Dissemination of the principles of weather-tightness
is critical for the long-term success of the programme. The
training courses are intended to be used as one of the channels
through which the information generated in the guide can be
filtered through the industry to the site workforce. The courses
will be aimed at influential members of the industry - such
as regulating authorities, specifiers, manufacturers, educators
etc - who will pass this information on to people they deal
with on a day-to-day basis, through presentations to their
These courses will be developed by industry in
partnership with educational providers. The material included
will be based on that supplied for the guide.
CINZ role in these programmes will be that of a facilitator
or organiser to help get things underway. Ownership, development,
and maintenance of the material will be the responsibility
of the participating industry sectors.
CINZ would welcome any comments, questions or
suggestions regarding either of these programmes.
