Case Study Details

Melbourne, Australia





Case Study

Under clear blue skies and set within the beautiful Treasury Gardens in Melbourne, Australia, Cubis Systems were asked to provide an installation training workshop for the STAKKAbox™ ULTIMA Connect access chamber system. This was part of a large-scale telecommunications infrastructure upgrade project, within Melbourne’s CBD.

The project presented several challenges, providing Cubis with the perfect opportunity to showcase the unique benefits only offered by the STAKKAbox™ modular access chamber system.

Project Challenges

The customer’s priorities were focused on a fast cost-effective installation with minimal impact on the surrounding environment & traffic activity. Consideration was taken for the landscaped area on installation with small machinery required over more heavy duty machinery that would usually have been needed for a large concrete chamber system.

  • Full details of existing underground services unknown
  • Densely-populated city location with high vehicle and pedestrian traffic
  • Limited 24 hour site access for installation

Traditional chamber options available could not resolve all of the project challenges as a pre cast chamber lacked onsite flexibility for the unknown existing services and a pouring in situ chamber would not have meet the time requirements nor deliver minimal interference with CBD traffic.

The Cubis Systems Solution

Cubis' STAKKAbox™ ULTIMA Connect was ideal, as the project required Class B loading requirements; made from Glass Reinforced Polyester Resin (GRP), ULTIMA Connects' twin-wall can achieve unsupported 90 tonne vertical loads, making it the perfect solution.

The internal dimension requirements of the chamber were 2400L x 1200W x 1200D.

Project Outcomes

The ULTIMA Connect chamber was installed within hours of the excavation being dug to the completion of the project including backfill and chamber cover. Cubis provided hand’s on training to the customer, demonstrating ULTIMA’s incredible simplicity with no skilled builders needed. Product features of the STAKKAbox™ range allowed for easy modification when accommodating existing services with duct entry boring completed using standard tools. As a result, minimal impact was caused to surrounding traffic and all possible WHS risks were eliminated.

For this particular customer, the Treasury Gardens Project was a début of the ULTIMA Connect to trial its ability in adapting to both Greenfield and Brownfield sites within regional and urban settings. As promised, the ULTIMA Connect surpassed all client expectations and has been strongly confirmed as the leading underground infrastructure product of choice.
