estimating the settlement / consolidation caused by the placement of the reclamation fill and.Tests done in the reclamation area are mainly aimed at: grading) may change during dredging, not all tests are useful nor need to be treated with the same care. Tests done in the borrow area are mainly aimed at determining: Therefore the geotechnical laboratory test programme of the fill area will differ from the test programme of the borrow area. For instance, the consolidation properties of the subsoil can be of great importance for the reclamation fill area, but are of less importance for the borrow area. However, the soil properties of interest will be different.

To a large extent, data collection for a reclamation fill area corresponds with the data collection for the borrow area.

In addition, within each category, the geotechnical data requirements for borrow areas and for reclamation areas are quite different and should be treated separately. The soil used for land reclamation purposes can be split into three main categories:Įach of these soil categories requires its own approach. These investigations will provide essential information about the physical and mechanical properties of the (sub)seabed. Since data about the types of soil, the quantities available, and the location of materials are directly linked to dredging costs, the highest accuracy in geotechnical and geological investigations is of great importance.
