Project Overview:
The project involved the design, construction and environmental approvals of three slope remediation solutions for Tweed Shire Council after the 2022 Flood Event. The three sites were in the vicinity of Uki township adjacent Rowlands and Chowan Creeks.
Quickway partnered with WSP as their designer and designed three separate structures to retain the adjacent roads and provide stability to the embankment. The design solutions included two shotcrete covered post and panel retaining walls and a gabion basket gravity wall on reinforced concrete footing. The project included the reconstruction of the adjacent road pavement and some minor drainage improvements.
Project Description:
The works involves the design and construct of three embankment restorations near the town of Uki in the Tweed hinterland.
The scope of works for all 3 sites includes:
- Site establishment
- Traffic Management Plans and traffic control to facilitate the construction of the Works
- Provision of site accommodation
- Searching for and protecting public utility services
- Maintenance of the existing roadway including adjacent slopes (fill embankments and cut faces) for the entirety of the Works
- Design, implement, maintain, and decommissioning/removal of temporary erosion and sedimentation controls
- Temporary earthworks design on steep and potentially unstable slopes
- Driven Pile wall construction with steel panelling and shotcrete facing
- Gabion Wall construction
- Drainage and Roadworks
Key Challenges/Highlights:
The project was complete ahead of time whilst maintaining access to the local residents at all times.
Whilst working in and around the challenging pristine waterways, there were no environmental incidents and best practice environmental controls were maintained during the construction duration.
At project completion, Quickway received a perfect 5/5 scorecard across all measured project metrics.
