INTRODUCTION

THE NATIONAL CONSTRUCTION CODE SERIESThe National Construction Code Series (NCC) is an initiative of the Council of AustralianGovernments developed to incorporate all on-site construction requirements into a singlecode. The Plumbing Code of Australia (PCA) is Volume Three of the NCC.FORMATThe NCC is published in three volumes:Volume One:pertains primarily to Class 2 to 9 buildings.Volume Two:pertains primarily to Class 1 and 10 buildings (houses, sheds, carports, etc).Volume Threepertains primarily to plumbing and drainage associated with all classes of buildings.ll three volumes are drafted in a performance format allowing a choice of Deemed-toSatisfy Provisions or flexibility to develop Alternative Solutions based on existing or newinnovative buildings, plumbing and drainage products systems and designs.

THE PLUMBING CODE O AUSTRALIAThe PCA is produced and maintained by the Australian BUilding Codes Board (ABCB) onbehalf of the Australian Government and each State and Territory government.THE AUSTRALIAN BUILDING CODES BOARDThe ABCB is established by agreement between the Australian Government and eachState and Territory government. It is a co-operative arrangement between the signatories.local government and the building industry.The ABCB s mission is to address issues relating to safety, health, amenity andsustainability in the design, construction and performance of buildings. This is achievedthrough the NCC and the development of effective regulatory systems and appropriatenon-regulatory solutions.The Board comprises(a) a Chair; and(b) the head of each Commonwealth, State and Territory department, statutory body,division, or agency that has the relevant administrative responsibility for I\lCCmatters; and(c) a representative of the Australian Local Government Association (ALGA); and(d) representatives of the building and construction industry, including onerepresentative with plumbing expertise.

Page 6 Australian Building Codes BoardThe Plumbing Code Committee (PCC) is the peak technical advisory body to the ABCB,with responsibility for technical matters associated with the PCA.The PCC comprises(a) the General Manager of the ABCB Office; and(b) one nominee each of the Australian, State and Territory Government members ofthe ABCB; and(c) representatives of the plumbing and drainage industry.THE PLUMBING CO EOF AUSTRALIA CONTENTGOALSThe goal of the PCA is to enable the achievement of nationally consistent , minimumnecessary standards of relevant safety, health, amenity and sustainability objectivesefficiently.The goal is applied so that(a) there is a rigorouslY lested rationale for the regulation ; and(b) the regulation is effective and proportional to the issues being addressed such thatthe regulation will generate benefits to society greater than the costs (that is netbenefits); and(c) there is no regulatory or non-regulatory alternative (whether under the responsibilityof the B08 d or not) that would generate higher net benefits: andd) the competitive effects of the regulation have been considered; and the regulation isno more restrictive than necessary in the public interest.

STATE AND TERRITORY VARIATIONS AND ADDITIONSEach States and Territory s legislation adopts the PCA subject to the variation or deletionof some of its provisions , or the addition of extra provisions. These variations, deletionsand additions are contained in appendices to the PCA.Flags identifying variations are located within the relevant provisions and at the beginningof relevant Tables. Additional provisions to a Part are identified at the end of that Part .DEFINITIONSWords with special meanings are printed in it lics and are defined in A 1,1.LEGISLATIVE ARRANGEMENTSGENERALThe PCA is given legal eff2ct by relevant legislation in each State and Territory . Thislegislation consists of an Act of Parliament and subordinate legislation which empowersthe regulation of certain aspects of plumbing and dr in ge installations , and contains theadministrative provisions necessary to give effect to the legislation.Any provision of the PCA may be overridden by or subject to , State or Territorylegislation. The PCA must therefore be read in conjunction with that legislation . Anyqueries on such matters should be referred to the State or Territory authority responsiblefor on-site plumbing or dr in ge installation matters.

Australian Building Codes Board Page 7PCA ADOPTIONThe adoption of the PCA is addressed in art AODOCUMENTATION OF CISIONSDecisions made under the PCA should be fully documented and copies of all relevantdocumentation should be retained.Examples of the kind of documentation which should be prepared and retained include:(a) Details of the Plumbing r Drainage Solution including .all relevant plans and othersupporting documentation.(b) In cases where an Alternative Solution has been proposed

(i) details of the relevant Performance Requirements and(ii) the Assessment Method or methods used to establish compliance with therelevant Performance Requirements and(iii) details of any Expert Judgment relied upon including the extent to which the

judgement was relied upon and the qualifications and experience of the expert;and(iv) details of any tests or calculations used to determine compliance with therelevant Performance Requirements and(v) details of any Standards or other information Wllich were relied upon.

STRUCTUREThe PCA has been structured as set out in AO 3 and shown in igure AO 3 It is theABC8 s intent that the Objectives and Functional Statements be used as an aid to theinterpretation of the PCA and not for determining compliance with the PCA.FURTHER REVI W OF THE PLUMBING CODE OF AUSTRALIARegular changes are planned to the PCA to improve clarity of provisions, upgradereferenced documents and to reflect the resL its of research and improved technology.
