Equipment investment provides viability in Vietnam

Foundation contractor Dua Fat Foundation has overcome challenging ground conditions on a new bridge project is Haiphong, Vietnam through investment in new equipment.

Dua invested in a new Liebherr 36-410 piling rig to help it deliver the foundations for the new River Cam crossing and ensure it could cope with high groundwater levels and waterlogged conditions at the site.

The 200m span bridge includes a 1km elevated approach on the western side that called for piled foundations to be constructed in a former mangrove, which has been cleared for the project.

Dua is installing 100 piles for the project and has used the new Liebherr rig for 80 of them to cope with the soft, saturated soils that extend to 50m below ground level. The piles have been constructed with a 10m rock socket into the underlying granite bedrock.
