Ports and Airports Platforms
Quay and berths
The introduction of the cast-in-place diaphragm walls radically altered the method of building harbour works.
Other techniques used in harbour works are piling (from pontoons or embankments), permanent prestressed anchors and fill consolidation (dynamic compaction, vibroflotation, drains), all are techniques in the Menard Bachy range of skills acquired over several decades of involvement in large domestic and international projects.
Reclamation and seabeds improvments
Construction projects at ports and airports involve vast land areas. Objectives can include stability of fill, increase of surface bearing capacity or an anti-liquefaction treatment (earthquake).
Frequently the reclaimed land is from wetlands or submerged areas and is achieved by using dredged or imported fill materials. This presents a challenge for the engineer to identify an economical means to improve such 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.
