Since the release of our recent post DBP Act – Are you ready?, BCA Logic have received further requests for information about the potential increased risk of using staged construction certificates (CC) to address the requirements for regulated design by design practitioners, and for design compliance declarations (DCD) required prior to the CC being obtained. A DCD for all regulated designs is required to be issued prior to the CC for the work contained within that CC (Clause 29, Design and Building Practitioners Regulations 2021). In this post, BCA Logic provides further clarity.
Another consideration when reviewing the use of staged CC’s is the roles and responsibilities of the Certifier under the Environmental Planning and Assessment Act and Regulations (EPA Act and Regs) and under the Building and Development Certifiers Act (BDC Act) which need to be considered in the first instance. Lets explore how these acts and regulations apply for Staged CC’s.
A Certifier must not issue a CC for building work unless:
The EPA Regs state that a person who has made an application for a CC may apply to modify the development the subject of the application or certificate (Clause 148 of the EPA Regs). The requirements of Division 2 of the Regs applies the same way as the original application. That is, a proposal by the applicant to modify the development the subject of a CC must include a new application and comply with all the relevant provisions of Division 2 of the EPA regs which outline the provisions for assessing and approving CC’s.
It is important to note that Section 6.8 of the EPA Act states that a CC has no effect if it is issued after the building work to which it relates is physically commenced.
Therefore, due to the above, the following applies to any staged (or modified) CC:
The BDC Act sets out the registration requirements, code of conduct and professional standards that a Certifier must comply with. Section 14 of the BDC Act allows the Commissioner to impose conditions on a Certifier’s registration.
One such condition is compliance with the ’Practice Standard for Registered Certifiers’. This standard states that staged CC’s are common practice but does provide cautions to the practice which include:
Staged CC’s include a greater risk of building works progressing beyond the issued CC.
It is common to see an application for a staged CC for a basement up to ground floor slab. It is also common to see the CC issued with only reference to structural plans and subsoil drainage plans.
When reviewing the above requirements to be considered by the certifier and the need for DCD for all relevant design components, it is considered that a staged CC for a basement may require the following for the works proposed:
The above list may not be exhaustive and is provided as an example only.
A common performance solution for basement carparks is to extend travel distances and the use of jet fans. This solution requires a Fire Engineering Report and referral to the Fire Brigade. If for any reason the performance solution is not approved or requires amendment prior to approval, it will result in a change to the design, or reverting back to a deemed to satisfy solution which may involve extra stairs. As such, approval of the performance solution is required before the CC for the basement can be issued.
The previous practice of seeking a staged CC for structural plans only for a CC was adventurous at best, flawed at worst, but today it is clear that the practice must evolve to include all relevant DCD’s, plans, specifications, reports and consents by authorities applicable to the proposed works.
