VARIO wall formwork with CB climbing bracket provide safe and cost effective solution for bridge piers
The Autoroute 50 extension project involves a 90 km long two-lane road connecting Gatineau and Montreal. As part of this project a 14.32 m wide, 380 m long bridge crossing the river Rouge is under construction by Construction Demathieu & Bard (CDB) Inc. from Saint- Jérôme, Quebec.
PERI supplied the form work for construction of the 2 abutments of the bridge and 4 piers which are between 21 m to 66 m high. The project had rigorous require- ments for concrete formwork of the piers. The formwork system must be light enough to match the site crane capacity. At the same time the formwork must be strong enough to withstand high concrete pressures resulting from use of self consolidating concrete in a 6 m high pour. Because of very dense re- inforcement in the piers, the tie location in the formwork should be flexible enough to allow for optimized layout of the ties.
VARIO GT 24 girder wall formwork combined with CB 240 climbing brackets provided the ideal solution for pier formwork. The climbing system supplied comprised of 6 platform levels. The top 3 levels for reinforcement and concreting work, the 4th level was the main level for formwork and the 2 levels of trailing platforms were dedicated for removal of climbing cones and concrete patching work.
