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.

Our digital engineering team are experts at building applications using 'Unreal Engine' -  one of the world's most advanced 3D graphics game engines.

We've used Unreal to develop a traffic simulation tool to test temporary traffic management schemes before rollout, and simulated construction works in an operational airport with AI driven crowd behaviours. 

The team's most recent application is a powerful marine construction simulator - fully developed in-house. The simulator combines intelligent 3D plant models and reality capture data to accurately place marine plant in a virtual environment and replicate its real-world capabilities. 

The tool enables our teams to simulate methodologies and iterate the positioning of plant and equipment around the design models. This is all done in a realistic environment with features such as accurate bathymetric data, reality capture point-cloud models, and real-world tide levels.  

The permanent works build sequence can be tested to ensure we avoid clashes during construction. Plant and equipment is programmed with its real-world performance and dynamic constraints to enable equipment limitations to be established and enabling features such as crane hook capacity to be determined in real-time.

We are leading the industry in simulation -  identifying and mitigating constructability issues during the design phase, driving program and cost certainty for our customers.

In marine environments, where the margin for error is razor-thin, temporary works aren’t mere enablers—they’re foundational to safe, efficient delivery.

Take the Swanson Dock upgrade at the Port of Melbourne. Our temporary works team engineered an innovative fender access platform, earning the a WorkSafe Victoria award for “Best Solution to a Specific Workplace Health and Safety Issue” 

Here’s what set it apart:

• Comprehensive access with one setup – The platform spanned 15 × 4 m and included removable mid‑level decks, enabling seamless access to all faces of the fender beams—front, soffit, and rear—for hydro-demolition, rebar replacement, and gunite spraying.
• Spatial efficiency in live operations – Designed to work within a daily operation window on the busiest container terminal in Australia, the platform kept works tightly within a small footprint.
• Reusability factors in long-term value – Not a one-off rig—it was engineered to be reusable for future fender rehabilitation works, reducing waste and delivering cost efficiencies over time.
• Award-level impact – The solution directly addressed specific HSE risks of working over water, giving our crews a safer, more controlled environment to complete high-risk tasks without compromise.

Why Temporary Works Matter

1. Prioritising safety at early design stages – Proactively engineering safe access platforms significantly diminishes risk in live marine settings.

2. Driving productivity through better access – Easier, safer access means faster cycle times and fewer quay-side delays.

3. Enabling precise engineering works – Demolition, rebar placement, and spraying all demand stable, safe working environments—temporary works deliver just that.

4. Promoting sustainability and reuse – Modular, reusable temporary works not only save time but also cut embodied carbon across projects.

By spotlighting temporary works as a core part of project delivery—not an afterthought—we’re reshaping how marine construction tackles safety, efficiency, and sustainability.

Our marine engineering specialists are always on the lookout for ways to minimise the impact of our works on sensitive environments, and a recent example comes from the New Bridgewater Bridge Project in Tasmania.

The project involves a new 1,300 m long bridge built across the River Derwent. The bridge is being erected from a temporary access platform, which crosses shallow tidal mudflats that have significant environmental, cultural and heritage importance. The temporary access platform allows continuous access for delivery and lifting of segments along the bridge alignment

The initial design for the temporary access platform included piles, but this approach was deemed to have significant environmental, cost and program impacts.

So an alternate and innovative construction methodology was developed by our marine specialists.

While the shallow tidal mudflats prevented the use of floating crane barges, interconnected barges placed on the seabed form the basis of the solution.

Standard (flat-top, 55 m long) barges have been floated into position at high tide, trimmed and ballasted down onto the mud flats. The barges are connected using specifically designed link bridges, allowing movement of equipment over a total length of about 800 m.

The innovative design caters for critical issues such as differential settlement of the very soft muds under cyclic loads; dynamic lifting loads; and load sharing between barges. Specific lift plans have been developed to address key risks during erection.

The linked barges design provides a safe and cost-effective solution while minimising the impact of construction activities on the environmentally sensitive mudflats. After the barges have been removed the mudflats are expected to recover completely. The barges and link bridges can also be re-used on other marine projects, unlike the original piled solution.
