PROJECT DETAILS

/ CONTEXT The Champlain Bridge spans the St. Lawrence River linking the Island of Montréal to the south shore.  The bridge is one of the busiest in Canada with approximately 160,000 crossings per day. In 2014, Jacques Cartier and Champlain Bridges Incorporated (JCCB) undertook a major project to reinforce the bridge due to structural deterioration. HBT AIM (civil engineering division of Delsan AIM) entered into a contract with Pomerleau Construction to move new structures into position for installation.  This very challenging operation involved lifting large, 65 ton trusses into place without imposing any loads on the existing bridge structure.
/ EXPERIENCE As leaders in the demolition of civil works, the HBT team offers years of experience to its clients and innovative solutions to complex and challenging projects.
/ SOLUTION HBT has developed and built an engineered modular hydraulic jacking system that provides the in-house capability to safely and economically lift heavy structural components up to an impressive height of 75 feet.
/ HBT utilized this technology to safely meet the requirements of this project by hoisting the new trusses from a barge positioned below the bridge in the St. Lawrence River.  The lifting system consisted of 4 – 400 ton capacity jacks mounted to the barge as well as a specially engineered support frame that was designed for precision movement of the trusses, which was critical to the success of the installation process.
