What is the IS rating scheme?
A scheme to guide (and rate) the sustainability of design, construction and operations of Australia’s infrastructure

IS Background, Ethos and Objectives
• A voluntary national sustainability rating tool for infrastructure
• Australian made, globally benchmarked, industry leading
• Guides and informs sustainability performance across the triple bottom line (environmental, social and economic)
• Full infra lifecycle (planning to decommissioning)
• Incorporates independent third party verification (assurance)
• Informs decision and management processes
• Benchmarks, quantifies and articulates performance
• Promotes and supports enhanced performance through better decision making, evidence, data and knowledge, and not greater capital investment

Each stage offers different visibility of tradeoffs, risks and opportunities, thus being valuable in its own right.
IS for decision makers
Consistent feedback suggests the need for the IS tool to be used to support pre “project” phases. ISCA’s response:
• Encouraging pre-tender IS registration and verification to inform procurement and tender processes
• Undertake research with industry to determine how the current IS tool could be used to inform Business Case and Project Development stages
14
Evolution of IS
Current or proposed ISCA IS development activities – in response to industry feedback:
• Operation IS Tool pilot trials
• Development of Workforce and Economic Themes
• Current Tool review and update (including flexible weightings)
• “Integrated infrastructure” and “Repeatable Assets”
• “How to use IS” Guidelines for – “Business Case & Project Development”; “Investors”; “Procurement”
• Industry Forums and Knowledge Hub

Whitsunday STP Upgrades
Proponent: Whitsunday Regional Council
Contractor: Tenix
Infrastructure Type: Sewerage
Rating Type: Design
Location: Whitsundays, QLD
Capital Value: $45m
Start Date: May 2012
Practical Completion: May 2014
The upgrade of two treatment plants at Proserpine and Cannonvale are to serve growing communities and meet the most stringent effluent discharge requirements to protect the Great Barrier Reef. They will also provide benefits to the local community by reducing sewage overflows, and improving noise and odour.
