World class tunnel infrastructure delivered through innovation and seamless logistical operation.

BMD partners with national and international companies to form expert teams to deliver world-class tunnel infrastructure within Australia.

In 2010, BMD was awarded our first tunnel infrastructure project, Brisbane’s Legacy Way. As part of joint venture, Transcity, the International award-winning project exceeded expectations and maintained high industry acclaim.

Transcity set out to deliver the project in record time using innovative construction methodologies, identify and utilise existing resources and leave a lasting legacy for the community.

The successful delivery of the project can be attributed to the ability to deliver unique and innovative design and construction solutions for both surface and underground activities, as well as the seamless logistical operation required in both the precast facility and tunnel excavation.

Despite the nature of the project’s fixed price, lump-sum design, construct and maintain contract, Transcity was able to adopt a number of changes and enhances in the overarching project scope. These changes resulted in cost and time savings, while enhancements were implemented to improve the final product. The scope changes were managed through a detailed risk evaluation and value for money assessment.

BMD’s integrated delivery method involved:

  • offline construction of tunnel portals to minimise motorist interference
  • effective spoil management utilising an underground conveyor tunnel into the existing Council quarry
  • an intense, proactive community engagement program resulting in community support for the tunnel and minimal complaints during construction
  • outstanding value for money service through combining experience with innovative design resulting in strong community outcomes.
