Upgrading existing buildings

Front cover of the handbook with a purple background and pictures of buildings in a narrow band across the front.The Australian Building Codes Board (ABCB) has produced a new handbook, Upgrading Existing Buildings Handbook. The Preface introduces the document as “one of a series produced by the ABCB … in response to comments and concerns expressed by government, industry and the community that relate to the built environment…on areas of existing regulation or relate to topics which have, for a variety of reasons, been deemed inappropriate for regulation. The aim of the Handbooks is to provide construction industry participants with non-mandatory advice and guidance on specific topics, specifically, buildings classified as Class 2 to 9 in Part A3 of NCC, Volume One”. This is a 47 page document.

Importantly, this handbook outlines a five-step process for scoping proposed new work in existing buildings, with a very strong emphasis at step four to determine whether potential deficiencies are actual deficiencies – i.e. the building does not meet a performance requirement of the National Construction Code. The takeaway message is that Performance Solutions may be the only practical solution to address actual deficiencies, and this is where a Universal Design approach will be most beneficial.
