As sustainable innovation gains prominence across the built environment, the pressure to deliver designs that meet both performance expectations and compliance requirements remains a constant focus for design and construction engineers.
For new sustainable materials to be seen as viable alternatives to conventional options, they must align with established engineering practices and regulatory frameworks. However, this can present compliance challenges and stall the progress of sustainable construction across the broader industry.
CodeMark Certificates of Conformity – like those awarded to SENSE 600®, a high-strength, lower embodied carbon reinforcing steel from the SENSE Solutions® range – provide a clear, pre-assessed compliance route that helps streamline both the design and approval process.
Designed for alignment, not complexity
SENSE 600® is manufactured from 100 per cent scrap steel and delivers up to 39 per cent lower embodied carbon while using 16.7 per cent less raw material than InfraBuild’s 500N reinforcing steel alternative.
From a compliance standpoint, it adheres to well-established frameworks and is produced in accordance with AS/NZS 4671 – Steel Reinforcing Materials, and is supported by Mill certificates and JAS-ANZ accredited Third-party certification. This ensures conformance with the same standards used for traditional 500 MPa steels.
It can be designed and specified using the same Australian Standards:
- AS 3600 Steel Structures
- AS 5100.5 Bridge Design: Part 5 Concrete
- AS 2159 Piling – design and installation
From a design perspective, there are no changes to software or workflows. Existing structural modelling platforms support the use of SENSE 600® in the same way as 500 MPa steel.
For infrastructure projects, where the National Construction Code (NCC) does not apply, this compatibility with Australian Standards ensures engineers can proceed with confidence.
The role of CodeMark for building applications
In building construction where compliance with the NCC and the Building Code of Australia (Volumes 1 and 2) is required, SENSE 600® also benefits from CodeMark Certificates of Conformity for specific applications, including longitudinal reinforcement and fitments in reinforced concrete columns.
“We developed SENSE 600® not just as a sustainable alternative, but as a drop-in solution,” explains Anthony Ng, Engineering Solutions Manager.
“CodeMark supports this by providing a formally pre-assessed compliance pathway that allows engineers to produce conforming designs using substitution tables. CodeMark does not alter the underlying standards. It removes the need for significant additional work where a higher-strength bar might otherwise trigger redesign or further review.”
Providing practical value in documentation & design
The value of CodeMark becomes especially clear in two common design scenarios:
- Fitment Substitution
SENSE 600® can be directly substituted for 500 MPa fitments, with equivalent load capacity, without redesign, provided the substitution follows the parameters outlined in the CodeMark certificate. This reduces documentation burden and streamlines coordination across the design team. - Longitudinal Column Bars
The higher yield strength of SENSE 600® enables more efficient reinforcement layouts, meaning less steel for the same structural performance. CodeMark formalises this through approved equivalency guidance, enabling engineers to realise efficiencies within a clearly defined compliance framework.
Seamless integration into existing workflows
One of the key concerns with new sustainable innovations is that they may disrupt established engineering or construction workflows. SENSE 600® was specifically developed to overcome this common challenge.
SENSE 600® requires no change in how engineers approach modelling, detailing or certification. The compliance pathway is not only equivalent to traditional reinforcement – it is, in many cases, simplified by the CodeMark Certificates of Conformity.
This approach empowers engineers to progress within the frameworks they know and trust, while still delivering on lower-carbon objectives.
Simplifying compliance. Supported by standards.
With its strength, sustainability, and standards alignment, SENSE 600® is simplifying and expediting the pathway to building and infrastructure compliance through Codemark conformity.
For infrastructure design, it complies fully with the relevant Australian Standards. In building applications, CodeMark certification provides an additional level of clarity – removing doubt, simplifying documentation, and enabling efficient substitution.
For engineers, certifiers and specifiers, the message is clear: SENSE 600® offers a confident compliance pathway backed by certification – not complexity.
