TECHNIQUE

Secant Piling

As part of Watercare’s installation of new infrastructure to service the Wynyard development, a new pumping station was to be installed by Fulton Hogan. March construction secured the sub-contract to install the secant piles required for 14m deep excavation to contain the wet well and pumping infrastructure.

The secant piled shaft required an excavation depth of 14m, meaning the piles had to maintain sufficient interlock to this depth. The solution settled on was a 750mm secant piled wall, that involved the installation of 60 piles to a depth of 22m.
