Concrib: 2009 Earth Award Finalist
The Trackstar Alliance Project earned Concrib a place among the finalists in the National Earth Awards this year.
The project entailed the design, construction, and certification of major retaining walls on the Corinda to Darra Rail Upgrade Project. Concrib provided concrete crib walls, which offered efficiency of construction (especially in the cut situation).
The stringent environmental control measures employed during this project earned Concrib a place among the finalists in Category 2 of the prestigious 2009 National Earth Awards.
Challenges that had to be overcome in this project included:
A rigorous contractor selection process
Trackstar Alliance awarded the project on the basis of compliance with rigorous technical, financial and safety criteria.
Technical challenges
For example, the walls at Darra are typically 3 to 6m in height and up to 190 m in length, with a curved face to match the track alignment. A total of 2000 square metres had to be completed.
Worker safety
Great emphasis was focused on Concrib’s ability to comply with some of the strictest site safety procedures in the civil construction arena. A number of critical activities (including working at height, materials deliveries, excavation, set out, and construction of the walls) had to be carried out entirely within the rail corridor and in close proximity to energised 25kV power lines.
Concrib, in partnership with Trackstar Alliance management and site personnel, successfully addressed these issues to ensure worker safety was never compromised.
Other major projects
Over the past 25 years, Concrib has been involved in a number of large-scale projects including:
- The Observatory at Reedy Creek
- Miami Beach
- Pacific Pines
- Everton Hills
- Crestwood Estate, Gold Coast
Crib wall with total wall area of approximately 1000 square metres, and a large section of wall at 10 metres in height, retaining engineered fill material.
A purpose designed Rock Catch Barrier for the capture of mobile rocks and the significant reduction of risk of damage to people and property. The barrier selected is a proprietary system, which is rated at 500 kilo-Joules. This equates roughly to the ability to arrest a one tonne boulder travelling at 100kph. The whole system was installed to strict specifications.
A design/construct service was provided to facilitate the construction of this stepped gabion weir built to withstand a one-in-one-hundred-year (Q100) event.
This was a full design/construct/certify contract comprising over 900 square metres of segmental block walling. The wall was constructed incorporating curves and sloping footings with heights up to 5 metres.
Over 8000 square metres of concrete sleeper walls (some up to 2.7 metres in height) were constructed. Sleeper walls are ideal for subdivisional housing lots because they present a narrow footprint therefore allowing maximum use of the land.
Investing in the future
Concrib’s vision of improving land values is reflected in the company’s dedication to both product development and improvement, and staff development.
Career development paths are established in collaboration with all employees and the company offers extensive on-the-job training from registered outside training organisations.
“We provide a broad-based training and development program,” said Martin. “In return, we expect high standards of workmanship. So our clients benefit from the best quality products delivered by skilled workers.”
Compliance is critical
In an industry where compliance is critical, Concrib is fully compliant with the National Code of Construction Practice and fully licensed with the BSA.
