|Materials||Mat-1||The project achieved a level 3 score of 7.24 points for this credit.
The Project achieved a 33% reduction in materials use impacts for VL2B-BIC, compared to the base case footprint. Key initiatives that led to this reduction included:
|Ecology||Eco-1||The project achieved a level 2.76 score of 8.33 points for this credit (equating to a total 17.63% ecological enhancement), with significant aquatic and terrestrial ecological enhancements including:
|Urban Design||Urb-1||The project achieved a level 3 score of 4.83 for this credit.
Key initiatives that led to this score included:
|Concrete Pavement Rubblisation – Australian First||Through design discussions and regular meetings within the project team, concrete fracturing techniques were raised as a method for existing materials to remain in-situ. These included pavement rubblisation and ‘crack and seat’ techniques. These techniques have previously been used overseas but are yet to be adopted in Australia. The pavement design team subsequently undertook a multicriteria analysis to assess the concrete fracturing techniques against traditional design options. Pavement rubblisation and crack and seat were identified as preferred options and approval to proceed was sought from TMR before being incorporated into the design. Trial sections have been undertaken along the VL2B-BIC road corridor to determine the feasibility of the process. While further trials are required during construction, concrete fracturing techniques were deemed to be feasible and have been implemented on the VL2B-BIC project.|
|Invertebrates habitat improvement – Australian First||The VL2T project has gone beyond the business as usual practice of including fauna sensitive road design considerations within road projects. While holistic fauna sensitive road design strategies and enhancements are another key outcome of the project (including structures such as culverts with fish passage and an extensive fauna underpass and fauna furniture), the additional focus on enhancing vulnerable invertebrate species and their habitat demonstrates the project’s significant commitment to sustainability and leaving a lasting legacy. The focus on invertebrate sensitive road design is a first in Queensland and in Australia.|
|Waste Calculator||As a response to this issue, TMR has developed an innovative Waste and Recycling Calculator, which has been designed to trigger and drive market transformation in the transport infrastructure sector. The purpose of the calculator is to:
· Estimate the type and volumes of waste generated from various types of transport infrastructure projects for the purpose of estimating costs and associated waste management (including resource recovery) and landfill disposal;
· Capture actual waste types and volumes for the purpose of reporting under Waste Reduction and Recycling Act 2017 requirements;
· Capture data on recycled materials utilised on projects to build a body of knowledge on the level of uptake by industry and drive strategies for increasing use in the future; and
· Generate evidence required to meet the Was-1, Was-2 and Was-3 IS credits.
In the short time since its release, the Waste and Recycling Calculator has demonstrated innovation and market transformation, with other State Road Agencies trialling the calculator on a significant number of roads projects in other States across Australia.
