Czajka sewage plant, Warsaw, Poland


Short construction period and high level of safety



With a cleaning capacity of almost 450,000 cubic metres per day, Czajka is the largest sewae treatment facility in Poland. On an area of 600,000 m2, 120 complex individual structures with varying forms and heights of the tanks had to be realised in a very short construction period of only two years. PERI delivered the required large quantities of materials to the construction site on time in close collaboration with the site management. Customised complete solutions with few different individual components ensured construction progress could be accelerated.

Equipped with appropriate platform systems, the TRIO, VARIO Gt 24 and RUNDFLEX wall formwork systems provided maximum safety for the construction site team as well as fast shuttering times. Complete large-area lifting units with all the required working platforms, access ladders and guardrails were moved from cycle to cycle. All anchor positions and element connections could be reached without any risk and safe working areas were available for the concreting work. The PERI RUNDFLEX formwork panels used could be adjusted quickly and easily on site in order to match the required radius. Horizontal connections took place using the proven BFD alignment coupler from the TRIO product range so that infill areas of up to 10 cm could be bridged with only one connecting part.

PERI UP reinforcement scaffold provided the perfect supplement for ensuring safe working conditions and PERI UP stair towers guaranteed optimal access means. The reinforcement scaffold units were extremely stable without requiring anchors and ballast and could therefore be moved without any additional assembly work. In those places where walls already concreted prevented direct access to the working areas, PERI UP stair towers provided safe and convenient access for site personnel. The metric grid of the PERI UP system allowed the installation of landing crossings with system decking and standard ledgers – without requiring any time-consuming adjustments of tubes and couplers.

    “With such a large-scale project, having a competent formwork partner is extremely important. The co-operation with PERI ensured adherence to the strictest safety requirements and, at the same time, reduced the labour costs.”
