A double-skinned concrete-block wall could define the edge of a new unloading area. Earth and rock would fill the enclosed space, with poured concrete filling gaps in the block structure. Compacting the earth and adding a concrete surface would produce a substantial platform. This is a proposed way to establish a usable quay within the island scenario, with no construction duration specified.

Building an island quay with concrete blocks and compacted fill
A proposed quay uses concrete-block walls, earth and rock fill, and a concrete surface to create an unloading point.
