CURRENT

As Logan’s population continues to grow, the need for improved road infrastructure becomes paramount. Recognising this, Logan City Council is upgrading Chambers Flat Road, a vital east-west link in the local road network. The project aims to enhance safety, improve road conditions, and provide better flood immunity. With construction currently underway and expected to be completed in 2024, the Chambers Flat Road upgrade is set to make a positive impact on the region’s transportation network.

Logan City Council has engaged SEE Civil to undertake the important upgrade.

The primary objective is to create a safer, smoother and more flood resistant road by widening it to 3.5m traffic lanes and 3m wide sealed shoulders.

This will allow for improved traffic flow and offer increased safety for everyday road users.

Additionally, the project will improve sight distances at bends and crests, further enhancing road safety.

One of the notable aspects of the Chambers Flat Road upgrade is the construction of a new bridge over Norris Creek, rising up to 8m higher than the existing road level.

This elevation aims to increase flood immunity, ensuring that the road remains accessible during severe weather events. Moreover, intersections at Kings Way and Greenvale Road will be upgraded to include dedicated turning lanes from Chambers Flat Road, improving traffic flow and reducing congestion.

To minimise disruption to local traffic, SEE Civil will complete construction works in four different zones. This staged approach allows for efficient progress while mitigating inconvenience for commuters. The project also includes wildlife devices throughout the construction process. These measures include fauna fencing, escape poles, culvert crossings, and nesting boxes, promoting the safe passage and protection of local wildlife.

As Logan’s population continues to grow, the Chamber Flat Road upgrade project will improve road infrastructure and connectivity. The project’s approach, including widened lanes, improved intersections, and enhanced flood immunity, will undeniably benefit both local residents and commuters.

Project Scope

  • Norris Creek bridge pre-load construction for the treatment of soft soils, with installation of high-strength geotextile foundations, installation of wick drains.
  • Bridge pre-load settlement monitoring via geotechnical instrument monitoring and a temporary RSS wall.
  • 3-span bridge construction including a shared user path connection and finishing works using a ‘Type 4’ rock pitching.
  • Drainage works (RCP, RCBC).
  • Bulk earthworks and soil treatments.
  • Fauna crossing construction and nesting box installation along the upgrade corridor.
  • Installation of guardrail.
  • Landscaping and rehabilitation works.
  • Street lighting and furniture.
  • Pavement works.
  • Signage and line marking.
  • Watermain lowering works.
  • Vegetation clearing.
  • Property reinstatement works (Including driveway works, drainage, fencing and landscaping).

Local and Indigenous Participation and Training

SEE Civil has adopted SEE Group’s corporate training and participation target policies for the project.

SEE Civil has set spending targets for Local and Indigenous Participation throughout project delivery and currently has two new industry entrant apprentices.

In addition, the project has secured funding for indigenous spending and training opportunities for employees.

Community Engagement

The project directly interfaces with over 80 private properties along the Chambers Flat Road alignment, road users, public transport operators, and property services including Australia Post and Logan Waste.

SEE Civil is currently working with the community to deliver project works to minimise disruption.

Safety

The project corridor interacts with over 49 overhead powerlines, which run parallel and perpendicular to the road alignment.  Planning of the works to comply with the asset owners’ strict exclusion zone offsets are crucial to the safety of onsite personnel.

Innovation

SEE Civil has worked with the Council and their designers to amend the ‘soft soil embankment design’ to suit the updated geotechnical condition encountered during project delivery. This includes the addition of geotechnical monitoring systems, high-permeability drainage layers, high-strength geotextile reinforcement, ground retention works, and surcharging.

SEE Civil is working with Council designers to optimise the design to mitigate the impact of discovered ground conditions to mitigate its impact on the construction programme and achieve value for money outcomes.
