Feature - Legacy Way
As at February, 2012, Legacy Way is progressing to schedule and has achieved 25 per cent completion as it enters it's second year of construction.
The western worksite team is working diligently to achieve upcoming milestones including the completion of the temporary acoustic building, measuring 80m long, 77m wide and 29m high. The building will be in place until 2014, and will provide noise dust and light mitigation for 24-hour tunnelling activities. The roof of the building will also be fitted with overhead travelling cranes used for TBM assembly and lifting of the concrete precast segments. The team is also working towards completion of the launch boxes in preparation for the arrival of the first tunnel boring machine (TBM) in April.
The tunnel for the spoil conveyor, which will carry spoil removed from site to the Mt Coot-tha Quarry, is drawing nearer to completion. Relocation of the water main located beneath the Western Freeway at Toowong will also take place in coming weeks. The relocation involves a change in construction methodology, which will result in less vehicle movement through local streets and ensures parks and dog off-leash areas remain fully operational.
On the eastern worksite, the team has almost completed excavation of the area east of the Inner Nothern Busway, in preparation for realignment of the Inner City Bypass.
The team is also working towards completion of piling activities to construct the walls of the cut and cover tunnel, forming the tunnel's eastern portal.
Offsite, at Transcity's facility in Wacol, production works are underway for the pre-cast concrete segments which will form the lining of the tunnel. The second of two TBMs, named Joyce, is also due to be commissioned at this facility in early April.
The Legacy Way Visitors' Centre in Toowong has seen an increase in community interest and engagement, with more than 100 new visitors to the centre in the last week alone, including a number of students from the University of Queensland.
BMD graduates visited the centre as well as the western work site in February as part of their Graduate Initiative program for 2012.
Graduate, Jackson Lane (Wiggins Island Coal Export Terminal Project) said the team's ability to stay on tendered schedule, given the difficulty in managing huge logistical challenges, was the most impressive part of the project.
This is a project being delivered by the Transcity Joint Venture, which is comprised of BMD Constructions ACCIONA & Ghella.
Ghella is a privately owned Italian based company established in 1894 that has expertise in tunnelling work around the world. With over 4,000 employees and operations in 14 countries, its vast tunnelling experience will be applied to this project.
ACCIONA is a global leader in infrastructures, renewable energies and water resources. One of Spain's largest corporations, the company operates in more than 30 countries on five continents. In Australia, ACCIONA has been operating for seven years and in that time has invested more than AU$630 million and employed more than 500 people.
Once complete, the project will comprise twin, two-lane tunnels, 4.6 kilometres in length, connecting commuters between the Mt Coot-tha roundabout in Toowong and the Inner City Bypass at Kelvin Grove.
BMD Group Executive Director - Operations Scott Power said, "BMD's involvement in the Legacy Way project highlights the integral part that local companies play in bringing stability, competition and long-term employment to Australia's construction industry.
"Private and public sector infrastructure clients have been looking for alternatives for major project delivery and BMD will continue to offer this by delivering projects with the long-term relationship-based approach that underpins our brand of contracting."
