Capability Statement

Our 'Canti-Traveller' is a purpose-built temporary mobile platform that facilitates fast, safe, low-impact construction of piled marine jetties and piers.

The innovative system, designed and fabricated by our in-house team, provides a platform for progressively installing new piles, propelling itself along the new jetty alignment using hydraulics. 

A piling gate fixed to the front of the Traveller allows pitching and driving of piles in a vertical position. If required it can be used to install raking piles using the gate’s hydraulics.  The piling gate also provides a working platform for cutting piles and welding headstocks.  Bent spacing can extend to 27 m, and it has a system for changing direction. The traveller supports a 450 tonne crawler crane, if required.

One of the primary advantages of the Canti-Traveller is its minimal ecological impact, not touching the earth except for the permanent piles it both drives and sits atop. Removing the need for marine-borne plant, it also operates independently of marine conditions, offering significant program and cost certainty.  This makes the Canti-traveller particularly effective in design and construct projects where the program can be optimized for maximum efficiency. 

We have a proven track record of successful installations in environmentally sensitive areas and a reputation for delivering safe, efficient, marine solutions for our customers. The Canti-Traveller reinforces our leadership in marine innovation and construction.

On the Granite Island Causeway Project in South Australia our team used the 'hand over hand' construction method to minimise environmental impacts and ensure delivery on time.

The 'hand over hand' method employs three concurrent work fronts:

• Front one installing the permanent piles
• Front two installing the grouted HDPE sleeves and the precast headstocks
• Front three installing the precast longitudinal girders and decks. 

As the structure advances out into the water it acts as a construction platform for the work crews to build the next stage. Each work front takes a similar duration, ensuring maximum certainty in productivity and schedule.  

Analysis was conducted on various construction approaches during the tender phase, including the use of jack-up barges or a temporary bridge structure to facilitate construction. However, the 'hand over hand' method was the only one capable of achieving completion by the target date. 

The other benefit of the method is its minimal footprint. Minimising the impact on the sensitive marine environment was a key consideration during the tender and design phases of the project. 

The adoption of the method, along with the use of precast prestressed deck units which pushed the span out as far as possible, minimised the number of pile driving operations further reducing the impact on the marine environment.  

The design and construction methodology was fit-for-purpose and extremely efficient. It resulted in on time and on budget completion and had a low impact on Victor Harbor's rich marine ecology.  

We helped revolutionise the design and construction approach for large-scale marine infrastructure on Rio Tinto's Chith Export Facility project in remote Far North Queensland.

The 350m wharf structure was split into seven, first-of-a-kind ‘jacket’ modules (the substructure) and six topside modules. Weighing approximately 680 tonnes each and standing 30m high, the jacket modules, with integrated dolphins, reduced the number of permanent wharf piles required from 100 to just 28, minimising environmental impact to marine life – a core focus for the Chith Export Facility team.

The wharf topside modules, placed on the jackets, ranged from 600 to 1400 tonnes and were fabricated complete with all services, conveyors, concrete roadways and access walkways.

In true ‘plug and play’ fashion, the modules were delivered and installed by a heavy-lift ship in a safe, clean and efficient operation.

The project, completed in just 10 months, was awarded the Australian Construction Achievement Award by Engineers Australia and the Brunel Medal by the Institute of Civil Engineers (UK).
