Resolve Group is project managing a dredging and piling contract at the Half Moon Bay ferry terminal for the Auckland Regional Transport Authority (ARTA).

New layover berths are being created 70 metres west of the existing berths, for use by local coastal vessels (ferries and barges).

Dredging to deepen the seabed has already removed approximately 2,500 cubic metres of sandstone. This allows flat-bottomed vessels to remain tied up at the new berths at low tide.

To minimise vibration, the piles are drilled rather than driven. One challenge is cutting through a very hard, cemented sandstone layer that requires frequent changing of the cutting teeth on the drill, which in turn, slows the drill rate. As the drilling must be done from a barge, another challenge is securely positioning the drilling rig during extreme tide and weather conditions as a great degree of accuracy is required for the drilling process.

Completion of the new berths is expected by the end of this year.

The New South Wales Roads and Traffic Authority (RTA) has recently engaged Resolve Group to provide procurement support and peer review of a proposal investigating the use of a moveable lane barrier (MLB) in Sydney. If the system is adopted, it will be the first installation in Australia.

The RTA is proposing the same moveable barrier system that Resolve recently assisted the NZTA to procure and commission for the upgrade on the Auckland Harbour Bridge. However, in Sydney the barrier will be installed on an urban arterial road with cross intersections. The 1500 metre barrier will require the Barrier Transfer Machine (BTM) to coordinate with intersection traffic signals, using onboard controls, to allow a smooth, non-stop barrier transfer.

In addition, Resolve Group are providing review of contract documentation, installation and commissioning planning, quality control of off-shore BTM manufacture, as well as providing framework planning for ongoing operation and maintenance of the MLB and BTM systems.
