Ryde Bridge

In February 2017, McElligotts was contracted by Duratc on behalf of Maritime Services to complete the rehab and painting of the Ryde Bridge, a steel bridge structure with two truss spans, a central lift span and approach spans.

The Ryde Bridge is located just west of the Sydney CBD and connects Ryde in North Sydney to Rhodes in Sydney’s West, spanning the Parramatta River. Constructed in 1935, this bridge replaced the need for ferries to carry supplies between these two points, creating a new convenience for road traffic, bikes and pedestrians. In addition, Ryde Bridge has significant significant local history being the only lift span bridge on Sydney Harbour since these types of bridges are no longer designed and built. Since its construction, Ryde Bridge has proved an important transport route for outer suburbs to access inner Sydney via car.

As part of the rehabilitation, McElligotts had to perform strengthening repairs on the entire bridge which included:

  • 11, 000 sqm of riveted steel truss
  • Establishment of scaffolding and level A containment
  • Safe working areas and maritime vessel management
  • Safe removal of the lead-based coating bridge below deck
  • Strengthening steel members
  • Concrete repairs to the footpath underside of the bridge deck
  • Application of anti-carbonation
  • Application of the new protective 3 coat system

McElligotts are currently finishing off this project and expect to complete the works within the required deadline.

Snowy Hydro

An international engineering marvel both today and at the time it was devised, the Snowy Mountains scheme, or Snowy Hydro, is a network of sixteen dams, seven power stations and 225km of pipelines and aqueducts in Southern New South Wales. The sheer scale of the project required 25 years of continual construction and connected new Australians with regional communities in the process. The project provides over 30% of the renewable power on the Eastern Australian electricity grid, which runs from Rockhampton to Melbourne, Adelaide and Tasmania.

Even today, talking about the Snowy Mountains scheme both conjures up memories for older Australians and inspires younger, technically minded Aussies. Such is the reverence for the scheme in Australian culture, that a Snowy Hydro 2.0 is in the works to deliver more renewable energy across the Eastern Australian grid. It’s a project that is cemented in Australian history as one of our defining moments, and as one of our first renewable energy projects, it’s helped ease the impact on our beautiful environment.

Over two decades ago, McElligotts had the pleasure of working on this iconic piece of Australian infrastructure. On what was the largest project we’d ever undertaken at the time, we applied specialised protective lining to 1.5km of 3m steel pipes. As both the stakes for failure and the quality demanded from the client were extremely high, we imported cutting-edge robot spraying technology from the United States to assist with the job. It allowed us to complete the massive undertaking in less than 12 weeks, with some of the most uniform paint depths we’d ever seen at the time.

This was one of the first times such technology was used in Australia and marked a turning point in McElligott’s history. Since that time, we’ve continued to invest in new technologies to provide efficient, durable and consistent results for larger infrastructure and construction projects.

In addition to honing our own capabilities and providing enhanced protection to vital piping in the Snowy Hydro scheme, we had the opportunity to employ over 60 locals in the process. The Snowy Hydro scheme is a vital part of the local economy and we were beyond pleased to work with locals and hone the skills of our existing workers.

Kangaroo Valley Pipeline Relining

From April to September 2013, McElligotts was contracted to work on the Kangaroo Valley pipeline by the Sydney Catchment Authority. It was a large job involving a complete strip and relining of a 1.8Km long, 2.6m wide pipeline.

The pipeline had only two access points, which definitely brought some hurdles throughout the project. Our initial work was to remove the old vinyl ester coating from the steel before abrasive blasting with our robotic blaster system. All waste from the old coating had to be safely removed from the pipeline using a commercial vacuum system. Once the required profile was created, we relined the piping with a solvent-less epoxy lining with robotic spraying equipment. Learn more about our specialised coating application services.
