Annual Sustainability Report – Gateway WA June 2016 Annual Sustainability Reporting Period Covering July 2015 to June 2016 Template for Major Projects with IS commitments This reporting template is to be used as a basis for a MRWA major project to produce a stand-alone sustainability report. While these indicators are a basis to what the report should include the author should be aware that they produce a report targeted at the intended report audience (it is linked to MRWA's Annual and Sustainability Report) and it should include all information necessary so that it can be read as a stand-alone report. This report is also an opportunity for the project to showcase its sustainability credentials and strengthen the project partners reputation for sustainable development. The indicators below are loosely based on the indicators of the Global Reporting Initiative (GRI) v4. Main Roads encourages the use of GRI principles when developing a public sustainability report for a major project and many of the indicators can be explained or defined further by referring to the information and guidance available via the GRI website. Data from the monthly reporting should also be considered for inclusion in the reporting. Project Name Gateway WA Topic What to report?

Tonkin Highway is a critical link in the Perth Road network helping to form a major ring road system around the eastern side of the city. It carries significant freight volumes and passenger vehicles through all hours of the day and this volume is expected to grow in the future. This particular area of the network is especially complex. In a distance of just over 8 kilometres, Tonkin Highway intersects with three of Perth’s major highways and the access roads to the Kewdale industrial area and airport terminals. The $1 billion Gateway WA Project is being jointly funded, with the Federal Government 1 Topic What to report? Content Reported contributing up to $686.4 million.

Provide a case study of an initiative or achievement Tonkin Highway / Leach Highway interchange design refinement. The original design provided for free-flow movements to save operational fuel and emissions in the long term. The refinement of the design through extensive design iterations resulted in the design of shallower baths which require less dewatering during construction and operation. This was achieved through a combination of varied road geometry, a shallower structural depth on bridges, and gaining approval from relevant authorities for partial penetration of aviation constraint surfaces. The length of concrete bath structures was also considerably reduced, with consequent reduction in demand for high- energy materials such as cement concrete. Drainage along Leach Hwy way changed from pumped to gravity system, eliminating operational energy requirements in the long term High modulus asphalt – The changing of asphalt binder from the traditional Class 320 bitumen to Class 600 was adopted to enable a higher modulus asphalt, which in turn means a thinner deep lift asphalt pavement for the same design life of 40 years. This resulted in an approximate 10 percent reduction in total asphalt quantity for the project. This is not only a significant cost saving but also reduces greenhouse gas emissions. Minimising total earthworks volume by optimising road geometry (e.g. lower embankments, raise cuttings) and minimising imported fill quantity and haul distance (e.g. maximise cut-to-fill and finding closer sources of imported) Purchase of two electric cars in the ‘pool’ fleet to encourage more serious consideration of cleaner, more efficient transport energy sources Use of LED street-lighting through the aviation constraints area, rather than the traditional HPS luminaires. 4 Topic What to report?
