Sea-Land Services Inc. were proposing to upgrade their container handling equipment at their Puerto Nuevo terminal, to rubber tired gantries. The terminal was formed by placing fill over the original mangrove swamp, and the surface was therefore prone to settlement under increased loading. Additionally, the subgrade had very low strength properties under a surficial crust of hydraulic fill material and the existing paving. In 1998, Nigel Nixon and Partners, Inc. were employed to undertake a preliminary design study for pavement options suitable for these conditions. The scope of work also included estimations of the potential magnitude of settlement under the new loading.
