Stantec Tower

Project data

Location: Edmonton, Alberta, Canada

A wide range of PERI products have been successfully utilized on this project, including TRIO, VARIO GT24, SKYDECK, SKYTABLE, PERI UP, and MULTIPROP, each providing its own benefit to the project. For safety, the upper working floors of the building’s perimeter were enclosed using RCS folding protection panels. The building’s core featured PERI’s brand new self-climbing ACS Core 400 system.



Safety, for both site personnel and pedestrian traffic around the building, was the number one priority during construction. The RCS edge protection system was used to avoid the risk of falling debris while at the same time protecting workers from adverse weather conditions. With fewer lost days due to inclement weather and higher productivity rates created by the feeling of safety, the tight construction schedule was maintained.

In order to maintain a tight schedule with limited crane availability, the massive elevator and stair core at the center of the building utilized PERI’s new ACS Core 400 system, designed specifically for large cores in high-rise structures. Used in combination with VARIO GT24 wall formwork, the C400 climbing system achieves the fastest cycle time possible for large cores, with the least amount of labour.

“The assembly of PERI equipment is very easy and fast. The climbing procedure of the ACS Core 400 is not complicated. This allows us to advance to the next level quickly to keep our cycle time low. “

“I am impressed with the quality of the equipment and the detailed assembly drawings. Also with the ACS Core 400 system we can achieve high productivity rates.“

PERI solution

The RCS-P self-climbing system utilizes standard PERI components to provide a complete enclosure that can be easily adapted to any building geometry. The system extends to an elevation that is 2.2 m above the concreting level and also provides edge protection for the three working levels below.

The RCS units are connected to the building at all times at 4 points by means of lightweight slab and climbing shoes attached to anchors set in the slabs. Using mobile hydraulic equipment, each unit can be quickly climbed without the use of the crane to the next level while always being safely secured to the building.

In order to be able to fly SKYTABLE units out of the building from within the RCS enclosure, RCS-P Fold Down units were used. These units are capable of opening and closing using integrated hydraulics to give clear access to the working level for cycling table forms. RCS Outrigger platforms were attached to the bottom of specific RCS units to provide a heavy duty material storage and landing platform on the two trailing levels. To provide safe access between the upper levels of the building, a 16m tall PERI UP staircase, enclosed with debris mesh, was mounted to one of the external RCS units.
