operated to optimise environmental, societal and economic
outcomes over the long term”.

profit industry (public & private) council.
Our vision:
Enhancing the liveability and productivity of our
major cities and our regional communities through
advancing sustainability in infrastructure planning,
procurement, delivery and operation.

8. 8
Why use the IS scheme (slide 2)
Master Planning
Inform/challenge master plan through TBL performance assessment of the proposed
underpinning infrastructure.
• Mitigate perverse outcomes
• Enhanced integration
• Appreciation of material impacts and opportunities
Business Case
Benchmark, evaluate and gap analyse for TBL aspects in the business case for a new
infrastructure project.
• Informs and articulates the ‘story’ underpinning the project need
• Establishes a TBL governance and performance framework which can be pulled
through each project phase
• Identifies and incorporates high value sustainability considerations early
• Informs procurement
• ‘Bottom up’ due diligence ESG assessment framework for investors
• Stream line approvals

9. 9
Why use the IS scheme (slide 3)
Design
An integrated framework which encourages ‘centralising’ of sustainability ownership,
increasing the likelihood of unlocking design solutions which can meet both fit for
purpose, cost and sustainability whole of life expectations and outcomes.
• Facilitates continuous improvement and innovation
• Facilitates sustainability in design processes
• Provides a reporting platform
Procurement
A TBL performance framework to assess and identify sustainability objectives, targets
and innovations pretender by client and as part of tender response by tenderers.
• Consistent industry language and benchmarks, thus reducing costs and improving
outcomes
• Reduces risks for clients and increases certainty for tenderers
• Provides measureable and quantifiable targets

10. 10
Why use the IS scheme (slide 4)
Construction
An industry developed best practise standard for applied sustainability in
construction associated with civil and infrastructure projects.
• Common industry sustainability language
• A framework which can be used to identify and value resource efficiency,
innovation and other environmental and community opportunities
• Centralises and maintains sustainability ownership during delivery
• Informs project KRA’s/KPIs and associated targets
• ‘Voluntary’ and outcomes based, therefore can be a project culture enhancer
Operation
A ‘bottom up’ applied sustainability tool and management framework which can be
used to benchmark asset performance and inform continuous improvement.
• Value creation and risk identification for investors
• Baseline asset/network TBL performance for asset owner/operators
• Facilitates identification of risks and opportunities and informs continuous
improvement targets
• Informs corporate reporting
