Overview

Varsity Lakes to Burleigh Interchange consists of Packages 1&2 out of a total of four packages of works within the overarching Varsity Lakes to Tugun Project that is undertaking an IS Program rating. The Project is a road upgrade consisting of an interchange upgrade and motorway widening including shared user paths.

Rating Highlights 

Category  Credits  Achievements/Risks 
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: 

  • Retaining the existing Reedy Creek Flyover, overall reduction of earthworks. Contributing 11% of the overall reduction   
  • Use of SMA and EME2, reducing the overall volume of asphalt pavement material contributing 81% of the overall reduction 
  • Use of Supplementary Cementitious Material (SCM) to replace a proportion of Portland cement content within approved concrete mixes   

 

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: 

  • Expanded native landscaping 
  • Offsetting for Koala and protected plants, including rehabilitation of Jack Ross Memorial Park 
  • Improvement of fish passage through installation of ‘fish friendly’ culverts, removal of waterway barriers and improvement of riparian areas 
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:  

  • Preparation of a VL2T Landscape and Urban Design Strategy (at the Program level to ensure consistency) and development of a package-specific Urban Design Plan (which responded to the overarching Strategy) 
  • Conducted internal reviews on urban and landscape design plans 
  • Engaged an Independent Design Review Panel (LAUDink landscape architects) to review and provide feedback on the overarching Strategy and package-specific plans 

Verified Innovations

Name Description
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.
