IS Rating Scheme Application and Process
Across the infrastructure lifecycle, there are three main ways that the IS rating tool (introduction to the IS rating scheme) is currently being used:
Planning phase support to apply the IS rating tool through various stages of infrastructure planning (project feasibility, development and procurement)
Registered use (Design, As Built, and Operation) to achieve a certified rating.
Non registered use (Planning Design, As Built and Operation) to assist benchmarking the sustainability performance of projects, assets and organisations, and with decision making for planning and delivery
These uses can be applied to the project phases as follows:
Planning (project initiation, development and procurement)
Planning phase support
Non registered use
Registered use – Design rating
Non registered use
Registered use – Design rating and/or As Built rating
Non registered use
Registered use – Operation rating
Non registered use
Planning Phase Support
The IS rating scheme can be used as part of the initiation, development and/or procurement phases of project planning to incorporate sustainability considerations and outcomes into the overall project phases.
The benefits of applying the IS rating scheme as part of project planning include:
- Significantly improved sustainability performance of, and outcomes generated by, infrastructure projects over their lifecycle
- More efficient use of public resources (reduces costs through greater energy efficiency, reduced waste disposal, and reduced risk management)
- Broader engagement across project’s team, not just sustainability practitioners, which strengthens clients’ sustainability commitments
- Better decision making during infrastructure procurement so as to deliver more sustainable outcomes
- Demonstrates that clients are committed to achieving sustainable development objectives
- Enhanced understanding of the importance of sustainability and how to consider it during infrastructure procurement
- Make available an effective and consistent approach to sustainability in procurement
- Functional briefs incorporating sustainability requirements become ‘core’ rather than being seen as an ‘add-on’. Designers and contractors will then understand the commitment of their sponsors and be more serious and innovative in responding to EoI/RFTs.
Project proponent contacts ISCA
ISCA and the project proponent execute a Short Form Agreement to register the project with ISCA during the planning phase
- ISCA provides ongoing support through the planning phase including:
Delivering a kick off workshop to raise awareness and gain commitment to sustainability with the broader project team.
Support the development of an IS Management Plan / Sustainability Strategy for the project.
Support to incorporate the IS rating into the project including clarifying aspects such as overall objectives, establishing the base case design and footprints, allocation of credits and scope outs.
Where required, verification of the base case design, footprints and/or scope outs.
Assistance to incorporate IS rating into the tendering process including the establishments of targets/objectives and review of clauses relevant to the achievement of an IS rating.
Ad hoc advice via emails/phone throughout the planning phase
Facilitation of regular monthly meetings.
IS Rating Scheme and Registered Use in Design, As Built and Operation
The IS rating scheme is a whole of life, dynamic and complete sustainability management system which:
- Provides a common national language for sustainability in infrastructure.
- Provides a vehicle for consistent application and evaluation of sustainability in tendering processes.
- Facilitates scoping whole-of-life sustainability risks for projects and assets, enabling smarter solutions that reduce risks and costs.
- Fosters resource efficiency and waste reduction, reducing costs.
- Fosters innovation and continuous improvement in the sustainability outcomes from infrastructure.
The IS rating tool, when applied to a registered project/asset has 4 main stages:
Registration is the first stage in the rating process. This stage establishes a formal connection with ISCA and gives the project or asset access to essential support including submission assistance.
To proceed to the assessment stage a Rating Agreement and invoice for the Registration and Support Feeneeds to be paid.
The assessment stage officially begins with a IS rating / Sustainability kick off workshop and is completed once the self-assessment and evidence has been prepared and is ready to submit to ISCA for independent verification.
The self-assessment involves the project or asset management team determining its own rating using the IS rating tool.
To progress to verification, a self-assessment and all applicable evidence needs to be submitted and the Verification and Certification fee needs to be paid.
The verification stage should align with the end of the relevant project milestone. For example, during the design rating, verification should begin once all documentation is completed and ready for submission at the end of detailed design.
Verification involves independent verification of the submission by industry experts, appointed through the ISCA Verifier Panel. One round of feedback will be provided before a final recommendation is made by the verifiers for certification.
To proceed to certification the assessor must accept the verified score given after 2 rounds of verification and they also need to waive any appeal.
Subject to meeting necessary requirements, ISCA will certify the achievement of a rating at either ‘Commended’, ‘Excellent’ or ‘Leading’ performance level. ISCA will issue and promote the rating widely.

1. Registration of Interest
Register your interest in pursuing a Design, As Built and/or Operational IS rating using the Registration of Interest form. This form requests information such as:
- The name of the project/asset registering for a rating
- The registrant
- The capital value of the project and/or or the operational turn-over of the asset
- The rating type and level targeted
- Endorsement and sign off from a senior decision maker
Where multiple parties will be involved in delivering a rating (i.e. JV contract, Public Private Partnership etc.), it is best if all organisations commit to the IS rating and are represented on the ROI. This joint agreement means that all organisations will be properly engaged through the process, and gives all involved the right to promote the pursuit of the rating and the ratings themselves, once certified.
Your assigned ISCA Case Manager will contact you following submission of the ROI to discuss your intent to register a project/asset for an IS rating.
2. Rating Agreement and Payment
Once ISCA receives a signed Registration of Interest form, a draft Rating Agreement will be issued to the primary contact for review and execution.
The Rating Agreement is a formal agreement between ISCA and the Registrant for the life of the rating(s).
Following negotiation and execution of the Rating Agreement, the Registration and Support invoice will be issued for payment.
Once the Rating Agreement has been signed, and the first invoice has been paid then the rating can get started with the delivery of an Infrastructure Sustainability kick off workshop.

Non Registered Use
Anyone can use the IS rating tool. Using the IS rating tool during the delivery of a project, as part of an assets operations, or as part of an organisational structure can have the following benefits:
- Provides a set of industry defined indicators that can benchmark the sustainability performance of projects, assets or organisation(s)
- Sets a simple and easy to use structure which can inform decision making and best practice approaches throughout the planning and delivery of projects and assets
There is no process to informally use the IS rating tool.
