The tender requirements for the Wynyard Wharf were to construct a new timber wharf with two separate floating pontoons. VEC provided an alternative to construct a concrete wharf structure supported by steel piles.

The Project

The project was for the replacement of the existing timber wharf with a new ‘insitu’/precast structure and design, and the supply and installation of floating pontoons.

The piles for the floating pontoon had to be driven with great accuracy to accommodate the tidal movement. This was achieved by using the existing timber wharf as a profile for the new piles as well as designing and constructing a moveable steel profile for those piles out in the deeper
water.

The wharf piles were driven through penetrations cut into the existing wharf deck, this provided us with accuracy as well as providing a safe work platform.

As the tender documents for this project did not provide an adequate geotechnical report, a test pile had be driven to determine the best method of pile installation. From the test pile it was determined that the best way to achieve the required pile penetration would be to bore the piles into the rock during this process.

Engineers from VEC Civil Engineering developed an excavator mounted pilebore and outer casing which was capable of drilling the competent rock below.

All works were completed around tidal movements with a tidal range of up to 3 metres.

This whole process was negotiated with the client and a “Guaranteed Maximum Price” per pile was developed before work started, thus giving the client surety of quality and price.
