Rapid response collaboration to reconnect communities

Damage of road infrastructure from the rainfall events of early 2022 in Southeast Queensland caused up to 50 min detours for cut off communities. The collaboration between parties allowed for immediate action and the fast tracking of the reconstruction of closed roads.

The initial design was for a temporary solution allowing partial opening of the road prior to completion of permanent works. This allowed for reduced inconveniences to the affected communities.

The team sought constructability and industry feedback during the design process to refine the design and minimise design work and material usage for the remediations.

Betterment and resilience

There was a prioritisation of sites that had the opportunities for further betterment/resilience treatment and funding, reducing long term maintenance and impact to road and community e.g. increased drainage capacity, long term erosion protection against heavy rainfall (up and down slope), flood modelling with climate change provisions.

Natural environment

Damage of roads and related road features occurred in mountainous areas near/within National Parks. The team made sure that National Park boundaries were understood to minimise impact on adjacent National Parks. They also undertook revegetation works in order to encourage the natural flora to regenerate, and coloured shotcrete to integrate better with natural environment. The team also utilised natural erosion control measures over synthetic type product.
