Building Surveyors in Western Australia

Western Australia's building certification system is administered by the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS), formerly known as the Department of Mines, Industry Regulation and Safety (DMIRS). The state uses the term "building surveyor" exclusively, and the regulatory framework is established under the Building Act 2011 and the Building Services (Registration) Act 2011.

WA's registration system divides building surveyors into three tiers. Level 1 Building Surveyors hold the highest registration and can certify all building classes. This level is further divided into Practitioners (who operate independently) and Contractors (who work for a registered building surveying firm). Level 2 Building Surveyors are limited to lower-rise and less complex buildings. Building Surveyor Technicians can conduct inspections but must work under the supervision of a Level 1 or Level 2 practitioner. The DEMIRS register provides current information on all registered practitioners.

Perth's building market is heavily influenced by the resource sector cycle. During mining booms, the construction industry faces significant labour shortages, including for building surveyors, which can lead to longer waiting times for certification services. Conversely, during downturns, competition among practitioners increases and consumers generally benefit from faster service and more competitive pricing. This cyclical dynamic makes WA's certification market distinct from the more stable eastern seaboard markets.

The Building Act 2011 requires a building permit to be obtained before commencing most building work. The permit issuing authority is either the local government or a registered building surveyor, depending on the type of work. For certified (uncertified) applications, the building surveyor issues a certificate of design compliance before the local government grants the building permit. For certified applications, the building surveyor performs both the design compliance assessment and issues the building permit directly, streamlining the process.

WA has specific construction requirements related to its unique geological and climatic conditions. Much of the Perth metropolitan area sits on reactive clay soils, which require specialist foundation design and certification. The state's northern regions, including Broome, Karratha, and Port Hedland, fall within cyclone-affected zones with wind loading requirements similar to North Queensland. The vast distances between regional centres mean that building surveyors servicing remote areas often charge travel premiums, and project timelines must account for inspection scheduling constraints.

The Energy Efficiency provisions of the NCC are particularly relevant in WA, where extreme summer temperatures in many regions make thermal performance of buildings a health and safety concern as well as a sustainability issue. Building surveyors in WA must verify compliance with the energy efficiency requirements, which often involve assessing insulation specifications, glazing performance, and the overall thermal envelope of the building. The state's 6-star energy rating requirement for new residential buildings requires certifiers to understand energy assessment methodologies and the interaction between building design and climate zones.

Recent reforms in WA have focused on improving consumer protection in the building industry, including tighter oversight of building surveyor practices. The Building Services Board, which operates within DEMIRS, handles complaints and disciplinary matters for registered building surveyors. The board has power to suspend or cancel registrations and can impose conditions on practitioners who fail to meet required standards. For consumers, checking the register before appointing a building surveyor is a straightforward way to verify credentials and check for any disciplinary history.
