IS Scheme Drivers

ISCA will achieve its mission through: • Continuing to improve and expand the IS rating scheme in

line with industry needs and lessons learnt from current experiences

• Collaborating with government agencies regarding the “upstream” use of the IS rating scheme

• Promoting and facilitating national training, education and knowledge sharing relating to infrastructure sustainability along the entire supply chain

• Contributing, facilitating and promoting industry forums and research on key policy and advocacy issues relating to infrastructure sustainability challenges and opportunities

8

ISCA Objectives

• Common national language for sustainability in infrastructure

• Consistent application and evaluation of sustainability in tendering processes

• 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 • Builds an organisation’s credentials and reputation in

its approach to sustainability in infrastructure

Decision Making “Applying the rating tool, our organisation has developed significant learning and is currently reviewing all design and construction related processes to embed this learning so that improved project outcomes can be achieved during the design, construction and operations of projects. For example, the requirement to review climate change risks and identify adaptation strategies for high to very-high climate change risks will be embedded into our existing Design Opportunity and Risk process.” “The IS rating tool changed the way in which we have gone about procuring materials for the project. We are confident that the changes that we have made will lead the wider supply industry to more sustainable outcomes.”

19

What some current users say:

Direct Benefits and Outcomes “Designs that used less concrete, less steel and resulted in less embodied carbon emissions and reuse of existing onsite wastes and designs that addressed climate change risks.” “Helped us to challenge the status quo in regard to design. We have identified opportunities to minimise material usage along with associated stakeholder and energy impacts.” “The sustainability initiatives collectively add significant value at nil-marginal additional cost.” “There was no additional cost to the project as a result of pursuing the rating.”

20


Credibility “The IS rating tool provides our organisation with independent recognition for the sustainable process and plan that we adopted for the project. As this is an outside body rating the projects sustainability performance, better recognition of our organisation’s sustainability systems is achieved.”

Tendering “The IS tool supported the establishment of rigorous tender requirements relating to climate risk, resource use, innovation, community initiatives and supply chain management. Accordingly our organisation will look to specify IS tool performance requirements within respective contract documents to assist with performance monitoring.”
