Commonwealth Greater Network Upgrade

The Cubis STAKKAbox™ access pit system continues to break ground in Australia. The modular twin-walled design offers product versatility and infrastructure capabilities not achievable with traditional pit options available on the market.

The new Commonwealth Building Development in conjunction with the Canberra Communications Upgrade, ACT, saw the introduction of the Cubis’ STAKKAbox™ ULTIMA Connect pit system. As part of the greater network upgrade project occurring across the Territory, installation of the ULTIMA served as a trial for both Greenfield and Brownfield applications in meeting new infrastructure requirements.

Project Challenges

• Closely located to boundary edge
• Ability to adapt to ongoing infrastructure developments
• Restricted installation time-frame

Pit safety, security and cost-efficiency were a major priority. The pit solution needed to provide ease of Brownfield installation without the aid of heavy-lifting machinery.

Traditional pit options, such as pre-cast pits, could not meet project weight or flexibility requirements when accommodating existing Brownfield services, whilst pouring in-situ would have resulted in increased traffic management, plant and specialised labor expenses.

Project Outcomes

Cubis’ project management and in-house engineering team worked closely with both the lead authority and contractor offering a customised STAKKAbox™ network access systems solution.

Rapid installation of the ULTIMA Connect was conducted within a number of hours, catering for the existing Brownfield services and restricted site area. Basic hand-powered tools were utilised onsite to make conduit entries and adapt connecting pieces as needed.

The innovative STAKKAbox™ pit system offered extensive cost savings to the client including flat-packed freighting capabilities, reduced traffic management and no heavy-lifting machinery or skilled labour. Combining ULTIMA Connect’s Class D load rating with the high security capabilities of a Cubis 911 locking cover assembly, enabled the highest standard of underground protection and long-term pit integrity to be provided.

For the Authority, the project’s success was marked by the effective and efficient installation of a Class D pit system for Brownfield remediation works overcoming challenges otherwise hindered by traditional approaches.
