The Hobart Airport Interchange project was required to replace the existing Hobart Airport roundabout with a solution that improved the existing traffic congestion and allowed for high projected growth for the Hobart Airport and the Sorell/Cambridge area.

After an initial design phase, the Department of State Growth elected to undertake the project as design and construct contract model to allow for innovative solutions from the industry. During the tender phase, Hazell Bros partnered with designer Cardno and proposed raising the Tasman Highway over the intersection, a design solution focused on the following key items:

Project Black Mountain Road – Landslide Remedial Works
Location Black Mountain QLD 4563
Client Noosa Shire Council
Key works Roadways, Flood mitigation
Status Current

The landslide, triggered by heavy rainfall in early 2022, spans over 130 meters in width, is as deep as a five-storey building, with a depth movement exceeding 15 meters. Geotechnical investigations confirm it as one of the most significant landslides impacting a road asset in the Noosa and Sunshine Coast region in the last 30 years. Extensive damage lies beneath the surface, requiring a careful restoration process.

Hazell Bros is over half-way through driving 266 steel-lined bored piles, each with a diameter of 900mm, to a depth of up to 25 meters. This includes the installation of some of the largest soil nails currently used in the southern hemisphere. The scale of the project requires an estimated use of 6,000 cubic meters of concrete, equivalent to two and a half Olympic-sized swimming pools, and 800 tonnes of steel.

The comprehensive remediation effort involves:

The recovery works are jointly funded by the Australian and Queensland Governments through the Disaster Recovery Funding Arrangements (DRFA).
