Ports and airports platforms
Quay and berths
The introduction of the cast-in-place diaphragm wall radically altered the method of building harbour works.
Other methods used in harbour works are piling (from pontoons or embankments), permanent prestressed anchors and fill consolidation (dynamic compaction, vibroflotation, drains), all techniques in the Bachy standard range of skills acquired in several decades of involvement in large international projects.
Reclamation and seabeds improvments
Construction projects at ports and airports involve vast amounts of land area. Objectives can be Self-bearing of fill , Increase surface bearing capacity or an Anti-liquefaction treatment (earthquake).
Oftentime the needed land is reclaimed on wetlands or in water by using dredged or imported fill materials. This presents a challenge for the engineer to identify an economical means to improve such expansive quantities of soil.
The engineer's primary objective is to induce a soil treatment which stabilises the fill for short-term and long-term performance.
