Infilling a heritage dock with sand to form the foundation platform.

A redundant dock basin is filled with dredged marine sand to create a stable, level platform for the stadium foundations rather than piling into deep water or demolishing the dock walls. This reuses an industrial heritage asset and avoids a more disruptive marine structure. The retained dock walls anchor the waterfront identity of the building.

Filling a redundant dock basin with dredged marine sand to form the foundation platform sidesteps the two most disruptive alternatives — deep piling through water or demolishing the dock walls — and retains the heritage waterfront edge as a genuinely load-bearing asset rather than a cosmetic one. The geotechnical logic depends heavily on the fill specification and compaction regime: dredged marine sand is variable in grading, often contains fines and organic material, and will consolidate under load at a rate that must be predicted accurately enough to inform the foundation and structural design above it. Long-term settlement behaviour and the performance of whatever ground improvement or surcharging programme precedes construction are the critical unknowns here, and with no provided case evidence against the record it is not possible to assess whether those risks were modelled conservatively or optimistically. The heritage planning dimension is the other lever: retaining dock walls as a structural element typically constrains their modification or removal if performance turns out not to meet design intent, so the team needs high confidence in the geotechnical model before the scheme locks in that constraint. Worth examining closely on any heritage waterfront site where the dock geometry is compatible, but the geotechnical investigation programme is the gate.
