In mid 2013, Uni-span welcomed Monadelphous Engineering Construction on board as new owners of the ORMA 80kPa Wall Panel system. The decision was taken to invest in the best system, offering them the best solution for their project.

The 6 month internal evaluation began as Monadelphous Engineering Construction had been investigating better ways to manage their projects, ensuring they are completed on budget and on time. Monadelphous have concluded that ownership in equipment, that they would otherwise regularly hire on successive projects, will enable much better managing and production on site.


Monadelphous settled on a Starter pack of over 400m2 of new ORMA wall panels and accessories. This enabled them to form a variety of wall lengths and heights, typical to many previous projects undertaken by them. Having a full inventory of what they own and peace of mind that back up and any additional components are only a truck away, allowed Monadelphous at their project for Unity Water, to reduce their overall pour sequence by 20%.

Monadelphous are self-performing and although being first time users to the system, after training by Uni-span representatives, achieved in excess of 10m2 per man-hour production rates.

This division will typically work on remote infrastructure locations and had to evaluate their investigations into the best system on a number of criteria:

  • Robustness of equipment
  • Class of achieved finish
  • Inherent safety features
  • Ease and speed of use


Uni-span’s ORMA system was awarded this order as it scored successively high on all these criteria. The equipment was used on Unity Water’s Maleny WWTW extension. Evaluation was also carried out on additional products with a view to further investment.

I have been very impressed with the system. The finish achieved is class leading, as is the back-up and support being only ever a phone call away.
