There are a lot of earthworks, dredging works and reclamation works during the construction of new locks like the new locks in Panama, or the new locks in Ymuiden.
Mostly, they need to be executed in different stages.
Also, the dredging of new access channels or the deepening of existing requires sometimes large quantities which must be carried out in stages.
Our 3D-models help to estimate this when building such projects.
Different soil-layers or execution methods make it also interesting to split-up the large quantities.
