Kurnell Desalination Plant, Sydney, Australia
Versatile use of TRIO for massive reinforced concrete walls
A large part of the constant increase in water requirements for the population of Sydney is covered by a new, enormous desalination plant. In the suburb of Kurnell, a number of structures were built on an area of 450,000 m² for this purpose which are used for treatment and storage, and includes an operations building for the personnel. Up to 250 million litres of drinking water can be produced per day.
A total of four contractors were responsible for completion of the structural work – the formwork solution for all partners was supplied PERI. With the TRIO wall formwork system, the massive 18.50 m high reinforced concrete walls with thicknesses between 0.80 m and 1.50 m could be flexibly and efficiently formed. At the same time, the PERI formwork planning took into consideration the various height offsets and wall sections which were constructed using single-face forming operations. The support for the 8.00 m bottom section was provided by the modular SB-A0, A, B and C brace frame systems so that single-face concreting in one pour could take place.
For the concreting sections at great heights, TRIO together with the CB climbing system was used – with help of SKS brackets, single-sided climbing could then be carried out. Here, the concreting cycle height was 3.00 m in each case.

“Together with PERI and the TRIO wall formwork, it was possible for us to also maintain the schedule for this important project. Through a combination consisting of formwork systems and service, PERI could once again prove its market leadership.”
