Brisbane Airport Corporation New Parallel Runway

 

As part of Brisbane Airport Corporation’s (BAC) New Parallel Runway project, STAKKAbox™ ULTIMA Hybrid was selected for the build and installation of an isolation pit for a water valve that would supply water to the site compound. Upon project completion, this would allow for contractors to move into the site compound facilities.

The stackable access pit sections of the STAKKAbox™ ULTIMA Hybrid allowed for variability in pit size, in addition to the flexibility of being able to build over existing services. This thereby proved to be an ideal solution for BAC’s New Parallel Runway project which required a very tight project completion timeframe of one (1) week.

Project Challenges

  • Installation of an isolation pit for a water valve required to supply water to the site compound for contractors
  • Provide a flexible, high quality product with very specific dimensions
  • Installation works were required around and over an already existing system
  • Working within a very restricted project timeframe of one (1) week

Cubis Solution

Product: STAKKAbox™ ULTIMA Hybrid
Load Rating: Class D
Internal Dimension (mm): 2200L x 1500W x 1200D

* A special precast concrete encased roof was also supplied to the BAC New ParallelRunway project.


Project Outcomes

After encountering timing issues onsite, CV Services approached Cubis to utilise the STAKKAbox™ ULTIMA Hybrid, confidently knowing that it would provide a flexible, high quality solution that would meet the tight project timeframe of one (1) week.

The hybrid pit system offered a wide variety of wall section lengths, enabling customisation of pit width, length and depth to suit the specific installation requirements of the project. Entries were quickly and safely formed on site with standard hand and power tools. With no individual section weighing more than 25kg, the STAKKAbox™ ULTIMA Hybrid eliminated possible health and safety risks associated with heavy lifting and the use of heavy lifting machinery for the pit walls.

Originally, the project required a depth dimension of 1050mm, however the depth requirement then changed to 1200mm as the installers decided to go deeper than initially expected. The STAKKAbox™ ULTIMA Hybrid was able to comfortably accommodate for this change due to its construction flexibility. To assist in the installation, Cubis supplied oversize pultruded beams to be cut down on site and were also able to provide the additional rise of 150mm within a 24-hour period. Had a traditional custom precast concrete pit or in situ method been utilised, this change would not have been accommodated as easily the same way it was with the ULTIMA Hybrid system.

Following succesful installation of the STAKKAbox™ pit, it was braced and backfilled. A temporary cover was used upon delivery of the custom encased roof, it was quickly installed, bracing was removed and the surrounding area was dressed. The STAKKAbox™ ULTIMA Hybrid provided a customised, secure and high strength solution to successfully fulfil a tight project timeframe with very specific dimension requirements.
