Design & Building Practitioners Act – what does it mean for building consultants?

In this edition of the Residential Focus, we review the Design and Building Practitioners Act (Act) and Design and Building Practitioners Regulation (Regulation) and assess their applicability to building consultants. We take a look at what kind of work a building consultant does, the classes of registered practitioner which may apply to a building consultant, as well as the new requirements or obligations which may now arise.

Building consultants

Building consultants play a key role in the construction industry. The term “building consultant” however is not defined in the Act or Regulation. In very general terms, a building consultant has been regarded as someone with particular knowledge, skill or expertise in a building or construction project, providing advice in a myriad of building issues before, during or after construction. Building consultants can advise on a range of projects, from small-scale residential building works to large-scale commercial developments, and are often involved in communications with stakeholders at all project stages, from planners and architects to construction workers and clients.

Before or during a project, a building consultant facilitates the progress of a project by deriving solutions to potential problems that may arise during various project stages. For example, a building consultant may assist in providing advice on compliance with relevant industry standards and codes. Building consultants can specialise in certain aspects of project consultancy work, such as work health and safety. At the completion of a project, building consultants can be engaged to assess the quality and compliance of building works to relevant standards, identify defects and recommend remedial works.

It's the latter aspect – identifying defects and recommending remedial works – which is our focus here. This work may include independently investigating, diagnosing defects, recommending rectification work, reviewing rectification work in progress or completed and reporting. In a litigation context, this may involve the preparation of reports, scott schedules, participating in conclaves with other experts and appearing as an expert witness.

Previously, building consultancy work was regulated under the Home Building Act 1989 (NSW). This ceased in September 2009. Given the regulatory vacuum since and the significant role which building consultants play in projects, it is important to consider how the Act and Regulation impacts on a building consultant.

Classification and registration

In previous editions of the Residential Focus, we gave an overview of how the Act operates with respect to the categories of regulated roles. Our design practitioner snapshot outlines the requirements and obligations for design practitioners.

To avoid penalties, registration is essential if you are preparing a regulated design subject to a design compliance declaration. Non-compliance with the design compliance declaration provisions can attract up to 1,500 penalty units for a body corporate ($165,000) and 500 penalty units ($55,000) for an individual1.

Remedial works, a new designer word?

A “regulated design” under section 5 of the Act is defined as either a:

  • design prepared for a building element for building work (where a building element is a fire safety system, waterproofing, internal or external load-bearing components essential to stability, part of a building enclosure or aspects of mechanical, plumbing or electrical required for BCA compliance2)
  • design prepared for a performance solution for building work, or
  • any other design of a class prescribed by the Regulation that is prepared for building work.

A “design” is defined to include “a plan or specification or a report detailing a design”3.

“Building work” is defined in section 4 of the Act to mean work involved in, or involved in coordinating or supervising work involved in, one or more of the following:

  • the construction of a building of a class or type prescribed by the regulations (being class 2 or a building that contains a class 2 part)
  • the making of alterations or additions to a building of that class or type
  • the repair, renovation or protective treatment of a building of that class or type.

In investigating and reporting on defects, a building consultant would ordinarily:

  • identify the defect
  • identify the breach with the relevant building code and standards
  • recommend a remedial scope of work for the defect.

In recommending remedial works for a building element or suggesting a performance solution, where that includes a plan or specification or report, the building consultant may be creating a design which is captured and regulated by the Act.

It would follow that, as a builder cannot carry out building work for which a regulated design is to be used unless a design compliance declaration is made by a registered design practitioner, the building consultant would need to be registered as a design practitioner under the Act.

Classification of a building consultant

A design practitioner is defined in section 3 of the Act as “a person who prepares regulated designs”.

If a building consultant is preparing regulated designs and intends to make a design compliance declaration, it must be registered under one of the classes of design practitioners under the Act.

Schedule 1 of the Regulation contains the 15 classes of registration for design practitioners – including Architectural, Building design (low rise), Building design (medium rise) and other specialist areas such as civil engineering, drainage, electrical engineering, façade, fire safety engineering, fire systems, geotechnical engineering, mechanical engineering, structural engineering and vertical transportation.

If the building consultant falls under one or more of the specialist areas, registration classification may be straightforward. However, the question of classification becomes problematic as many building consultants have an expertise that is more general in nature.

The generality does not arise from a lack of skill or expertise of the consultant, to the contrary, many building consultants possess a wealth of knowledge and experience that may exceed their specialist counterparts. But just as the term “building consultant” is not readily defined, it encompasses a broad range of consultants with varying disciplines and qualifications which may range from a building degree, diploma or possibly many years of trade experience.

In the absence of any specific degree (such as architecture or engineering which can be readily classified), a building consultant would likely be classified as either:

  • Design Practitioner – building design (low rise), or
  • Design Practitioner – building design (medium rise).

Schedule 2 Part 2 sections 6 and 7 of the Regulation set out the qualifications, experience, knowledge and skills requirement for design practitioners of these classes which we covered in our design practitioner snapshot.

Implications of registration classification

Several shortcomings arise out of the limited classes for registration:

  • building consultants effectively face a minimum academic qualification threshold (degree or diploma in building design or architectural design) in order to operate in the multistorey class 2 space. Qualifying will be time prohibitive for many
  • building consultants who don't meet those requirements will not be able to prepare regulated designs for remedial works for class 2 buildings exceeding four storeys
  • the above will create a shortage of supply of building consultants able to provide remedial scopes of work
  • that shortage is unlikely to be filled by architects and engineers, who tend to avoid the space
  • in the context of increased regulation, the substance of regulated designs for remedial works may trend away from performance solutions and serve to increase remedial costs
  • if a two-tier approach to these services can be adopted, comprising dispute advice now, regulated design (by others) later, that duplicates consulting costs and may result in inconsistent advice vs designs and unfunded rectification outcomes.

Next steps

If you are a building consultant, you should carefully consider whether:

  • your particular mode of practice falls within the Act
  • if so, are you able to comply with the Act as a registered design practitioner
  • if not, can your practice be restructured away from class 2, or
  • are there adjustments which can be made to your designs (plans, specifications and reports) which bring the context and nature of the services being provided outside the operation of the Act?

If you are registering under the Act, deemed registration is available during the transitional period which ends on 31 December 2021.

If you lack the formal qualifications required by your class of registration but have 10 years or equivalent of industry experience, you can still make an application for an alternative pathway of registration allowed under section 97 of the Act. This requires you to complete a competency assessment of knowledge and skills for your class of registration (low rise and medium rise only). Please note the alternative pathways apply up to 30 June 2022.

If registering, then within your practice you should map out processes required for compliance and consider what may need to change. In particular, you will need to familiarise yourself with the requirements for a regulated design and a compliance declaration.

The legislation has been in effect for just over a month. The question whether there will be an “open” category in the registration classes at a later stage would be an interesting proposition.

We recommend you seek legal advice if you are unclear how the classification or registration provisions under the Act and Regulations affect you.
