Schedule 1 requirements have a long history in Tasmania There
were requirements in the 1994 building regulations and these were
not included in the introduction of the 2004 building regulations.
Regulators thought that designers and building surveyors would
endeavor to keep the standards to the appropriate level.
Slide 3
In 2011 Building Standards were approached by some designers
concerned with what they saw as a continual decline in the standard
of building design in the market place. Some building surveyors
also raised concerns. Investigators found that poor documentation
was often a contributing cause of dispute between parties.
Slide 4
Building Standards contacted all industry stakeholders
regarding these concerns and were encouraged to address the
situation for the long term benefit of the building industry. A
working group was formed with representation from the following
areas.
Slide 5
Building Designers Association of Tasmania (BDAT) Australian
Institute of Building Surveyors Tasmanian Builders Association
Councils (Permit Authorities) Engineers Builders Building Designers
(Independent groups) Private Building Surveyors Plumbing Inspectors
Compliance Investigators ( Both HIA and the Master Builders
Association were invited to participate )
Slide 6
The findings of the working group were introduced into the
Directors Specified list as Schedule 1 in November 2012. Building
Standards has now conducted a full review of the Schedule. All
categories of building practitioners and other stakeholders were
invited to make comment as well as the original working group. All
comments were taken into consideration and there has been a
reduction of some requirements and a redesign of the layout with
added explanatory information. Schedule 1 now reflects the minimum
standard of documentation required for class 1 and 10 buildings in
Tasmania.

SCHEDULE 1 Benefits of Good Documentation Better protects all
stakeholders. Designers know the minimum acceptable level of
design. Client knows what they are paying for. Building knows what
they are quoting for. Building surveyor knows what they are
assessing for compliance. Less disputes between parties. Builders
can quote apples with apples in the market place.( Meaning the
person that should have won the work gets the work) Less variations
though out the build. Better quality builds. Less cost blow outs
and associated issues i.e. :Litigation, complaints, loss of
reputation.

Communication Disputes Difference between what the client
thinks they are getting and what the builder has actually quoted
for. Good documentation and specification protects all parties.
Small Variations Often ends in dispute between parties often not
documented by builder however often is by owner. Diarize and have
parties sign if possible. Sign brochure etc. state agreed price and
list any relevant details.
Slide 37
Design documents with erroneous wording, such as Not for
Construction marked on them. Building Standards policy is to ensure
that designers are following good design practices and meeting
minimum acceptable standards. Including such contradictory
information would be very confusing to the builder and could create
non-compliance problems from the date any work starts (see the
duties of designers in section 13 of the Act sufficiently detailed
for the builder to build from. The view of Building Standards is
that any such documents labelled with those words, fall short of
professional standards expected of a building designer. Before
accepting that application for assessment for a CLC, the
responsible designer is to provide the BS with amended copies of
any such documents. Building surveyor is entitled to reject the
application as being incomplete or is too deficient to be
assessed.
