Albian Sands, Fort McMurray, Canada
Flexibly adapted to high loads
To the north of the Canadian city of Fort McMurray, oil sand is surface mined from Canada´s largest bitumen deposit and oil is subsequently extracted using a complicated and expensive process. For the construction of a production plant, massive foundations and rectangular columns along with enormous reinforced concrete beams with heights of 4 m were required. The use of self-compacting concrete resulted in high concrete pressures.
The VARIO GT 24 and TRIO wall formwork systems, in particular PERI UP Rosett and MULTIFLEX for the beams, proved here their flexibility. Through the planning and supply of formwork and scaffolding from one source, the MULTIFLEX slab formwork and PERI UP shoring could be perfectly matched. Both systems complemented each other ideally so that also during the concreting of massive structural elements at large heights, over 40 kN per leg could be safely transferred.
The birdcage scaffold with a basic grid of 1.50 m x 1.50 m could be reduced to 75 cm widths in areas of high loads. Below the working platforms without concrete loads, the PERI UP grid dimension could be doubled to 3.00 m The modular structure and metric grid resulted in optimal adjustment to the load sizes as well as complex building geometry - with system components, without any time-consuming coupling of scaffold tubes. Furthermore, this also allowed three sets of staircase access to be integrated into the scaffold construction.

Project Superintendent
“There are many shoring systems and also a lot of working scaffold on the market. But PERI UP is the only system which equally satisfies both aspects. In particular, the high loadbearing capacity impressed me.”
