Pacific Motorway Upgrade: M1/M3 Gateway Merge Project

Guardian Goalposts



Case Study

As part of Queensland Government’s Pacific Motorway Upgrade: M1/M3 Gateway Merge Project, facilitated by the Department of Transport and Main Roads, Cubis’ Guardian Goalposts were supplied to assist in the effective management of both vehicles and personnel working safely around overhead cables.

The Pacific Motorway Upgrade: M1/M3 Gateway Merge Project saw the installation of five (5) sets of Guardian Goalposts. The Guardian Goalposts’ lightweight and non-conductive telescopic pole system was able to provide a highly visible proximity warning of nearby overhead cables on site.

Project Challenges

  • Large project area with several locations requiring overhead power line protection systems
  • Effectively accommodate changing work site conditions throughout the progression of the project
  • Provide a purpose-built engineered solution that offered cost and time benefits
  • Provide a flexible and sustainable solution throughout the life of the project that reduced OH&S risk

Cubis Solution

Project Outcomes

The simplicity of setting up Guardian Goalposts meant that the system could be assembled and disassembled by one person in minutes, without the need to perform preliminary digging to locate existing underground services. Guardian Goalposts do not require drilling poles/holes for conduit uprights or assembling stabilising rope systems. Driving star pickets into the ground was also not required, thereby reducing OH&S risk associated with such activity and increasing the flexibility of use of the product.

Due to the project spanning a large area with several locations requiring overhead powerline protection systems, the Guardian Goalposts system was able to be reused across a variety of height and site requirements and involved little to no maintenance over time. Once disassembled, the Guardian Goalposts were easily loaded into a standard car and stored on site without the need for ample storage space. Due to the sustainability of the product, Guardian Goalposts offered the versatility to accommodate the changing landscape and requirements of not only the Pacific Motorway Upgrade: M1/M3 Gateway Merge Project, but also future projects completed by the Department of Transport and Main Roads.

By providing a product that meets Australian Constructors Association guidelines and Safe Work Australia standards, Cubis was able to successfully provide an innovative engineered solution, compared to traditional non-engineered overhead warning systems, that effectively isolated hazards and visibly enforced safety zones across the project site. This resulted in a solution that not only allowed for total flexibility across the life of the project, but also delivered a high level of OH&S management while providing both cost and time benefits.
