JT Harvey Construction, a Darwin-based company specialising in civil and commercial projects, was integral in delivering the Tiger Brennan Drive and Berrimah Road Overpass project.

“We completed all the drain works, culverts, headwalls, wingwalls, and even the pedestrian underpass for pathway traffic,” said Director Jeff Harvey, who founded JT Harvey Construction in 2016. These critical components not only facilitated safe pedestrian access but also supported the overall structural integrity of the bypass.

The Northern Territory’s notorious wet season posed significant challenges during the project, requiring JT Harvey Construction to adapt their methods. “The monsoonal season is hot and crazy—imagine pouring concrete with 90% humidity. It’s something you get used to,” Harvey said. “We had to carefully consider the impact of rain while lining the drains with concrete. Luckily, the wet season didn’t significantly impact our progress.”

“On a big site like this, things change by the hour,” Harvey noted. “We worked hard to complete our package so that other trades could move forward behind us. Collaboration was crucial to keeping the project on track.”

Beyond technical execution, JT Harvey Construction upheld its commitment to safety and sustainability. “Safety is ingrained in everything we do. My background in compliance ensured that we met every requirement on site,” Harvey said. The team also participated in workforce engagment initiatives led by principal contractor Sitzler, including milestone-driven site-wide activities like appreciation barbecues that fostered camaraderie across teams.

The results of JT Harvey Construction’s work are already evident. “The methods we implemented based on the construction design are performing as intended,” Harvey stated. “It’s rewarding to see the project not just completed, but truly making a difference for the community.”

NTEX Champions Sustainability at Tiger Brennan Drive and Berrimah Road Overpass

NTEX drives sustainability in the Tiger Brennan Drive overpass project by recycling construction waste into resources.

NTEX

The Tiger Brennan Drive and Berrimah Road Overpass project is not just a marvel of engineering but a benchmark for sustainability and circular economy principles in the Northern Territory.

Among the key contributors to this transformative project is NTEX, a leader in environmental remediation, waste management, and innovative recycling solutions. Their role in this project underscores their expertise in turning construction waste into valuable resources while promoting sustainable practices.

NTEX, founded in 2010, has carved out a reputation as a pioneer in resource recovery and the creation of a circular economy in the construction industry. Their work on the Tiger Brennan Drive project exemplifies their mission.

“NTEX supported Sitzler to achieve their sustainability goals through the recycling of demolition concrete from the project,” said Eileen Breen, Business Development Manager at NTEX. “We received 1,226.2 tonnes of waste concrete at our Code Red Resource Recovery and Recycling Facility in East Arm, where it was recycled into type 2 aggregate materials.”

These aggregates were not just repurposed; they became an integral part of civil projects across Darwin, including a hardstand laydown yard for Sitzler. This process not only reduced landfill waste but also conserved finite quarried resources, aligning with the Northern Territory Government’s Circular Economy Strategy goals.

What sets NTEX apart is their use of groundbreaking technology to achieve sustainability outcomes. For the Tiger Brennan Drive project, NTEX employed the Arjes Titan 900 and Rubble Master crushers and shredders, imported from Germany and the first of their kind in Australia.

“These machines include magnetic separators to remove reinforced metal bars in concrete, as well as blowers and inbuilt screening units to eliminate light plastics and organic material,” Breen said. “This ensures the production of superior aggregate products that meet Australian Standards.”

Such advancements serve as evidence of NTEX’s commitment to innovation in recycling, allowing them to achieve an impressive 83% resource recovery rate since July 2020, processing over 166,000 tonnes of waste.

The Tiger Brennan Drive project highlights the benefits of a circular economy approach. By recycling construction waste into reusable materials, NTEX has significantly reduced the environmental footprint of the overpass project. This approach not only minimises landfill but also supports local industries by supplying high-quality recycled materials for infrastructure development.

“The circular economy benefits extend beyond waste management,” Breen said. “They include reductions in greenhouse gas emissions, resource conservation, and economic opportunities for local communities.”

Beyond environmental sustainability, NTEX’s work supports local employment and economic growth. Their efforts complement the broader objectives of the Tiger Brennan Drive project, which has engaged over 1,700 workers, including Indigenous employees and apprentices, in collaboration with lead contractor Sitzler.

The use of NTEX’s recycled materials further supports the Territory’s economy by reducing dependency on external resources. This aligns with their ongoing initiatives to expand recycling activities, such as launching the NT’s first tyre recycling service and developing plans for a marine resource recovery hub.

As NTEX continues to innovate and expand, their contributions to projects like the Tiger Brennan Drive Overpass demonstrate the transformative potential of sustainable practices in infrastructure. Looking ahead, their commitment to advancing recycling technologies and promoting a circular economy positions them as a vital player in the Northern Territory’s growth.

“The Tiger Brennan Drive project is a great example of what’s possible when sustainability is prioritised,” Breen said. “It’s not just about managing waste; it’s about creating value for communities, businesses, and the environment.”

NTEX’s involvement in the Tiger Brennan Drive and Berrimah Road Overpass Project illustrates the power of innovation and collaboration in delivering infrastructure projects that benefit people and the planet. By combining cutting-edge technology with a commitment to sustainability, NTEX has set a standard for responsible construction practices in the Territory and beyond.

ARMS Nurtures Long-Term Sustainability in Civil Landscaping

ARMS delivered sustainable landscaping solutions, ensuring durability and environmental resilience for Tiger Brennen Drive and Berrimah Road Overpass.

Aussie Rental Maintenance Services (ARMS)

Aussie Rental Maintenance Services (ARMS) delivered high-quality commercial landscaping solutions to enhance the final stages of the infrastructure upgrade in the Tiger Brennan Drive & Berrimah Road Overpass project. Specialising in sub-grade preparation, topsoil placement, spray grass application, tree planting, and irrigation, ARMS ensured the project’s landscaping met durability and environmental sustainability standards.

“Our team was responsible for sub-grade preparation, topsoil placement, direct seeding, and jute mat installation to protect against erosion,” said Silas Thorley, General Manager of ARMS. “The unique challenge of this project was managing the steep gradients and the impact of the wet season, which led to higher erosion risks and rapid weed growth. Our experience in commercial landscaping and site maintenance allowed us to overcome these obstacles effectively.”

In the Northern Territory, managing steep gradients and wet season challenges requires a combination of erosion control, drainage management, and vegetation control strategies. Techniques such as jute matting, hydroseeding, and rock armoring help stabilise soil and prevent runoff, while stormwater diversion channels and vacuum excavation mitigate waterlogging during heavy rains.

To control rapid weed growth, pre-seeding with native grasses, mulching, and targeted herbicide application suppress invasive species and promote long-term stability.

The landscaping work through head contractor Sitzler covered various large batters, 4 major detention basins, the grass centre median, and garden beds on both the north and south ends of the overpass. ARMS also implemented permanent and temporary irrigation systems, ensuring long-term sustainability and ease of maintenance for the site.

This project is just one of many major infrastructure jobs ARMS has undertaken, with recent work including landscaping for the Northern Land Council Building in Berrimah, Kangaroo Flats Training Ground, and Tindal RAAF Base.

By combining expertise with a deep understanding of the Northern Territory’s unique environmental conditions, Aussie Rental Maintenance Services continues to deliver high-quality, sustainable landscaping solutions for major civil and commercial projects.
