Overview
Design and construct a full revetment wall reconstruction using concrete foundations supported by screw piles, precast wall tops, civil drainage works, slope stabilisation, rock placement, temporary works, and landscaping – all completed from floating plant.
Challenges
The original design proposed the use of deep stabilised sand foundations; however, this approach proved insufficient due to inadequate bearing capacity to support the required loads. Additionally, the method was heavily impacted by tidal fluctuations, significantly limiting safe and practical working windows. These constraints posed major challenges to both the construction schedule and overall project feasibility, necessitating a re-evaluation of the foundation strategy to ensure structural integrity and improved constructability within the tidal environment.
Solution
Piletech redesigned the foundation system using screw piles, allowing the footing toe level to be raised. This expanded workable tidal windows, increased productivity, and reduced the reliance on barge-based earthworks disposal and ramp access.
