For ten years, the Structura team has carried out inspection and assessment mandates on most of the major bridges in the metropolitan area. Various mandates have led us to work on design projects and to carry out legal and technical expertise on a wide range of structures, across Quebec and internationally. Structura is also engaged where structural engineering can improve the lot of entire communities.
Inspection and assessment of the Jacques Cartier Bridge’s load-carrying capacity
Montréal and Longueuil
From 2015 to 2018, Structura performed a complete inventory of the entire Jacques Cartier Bridge, a general inspection of the entire bridge as well as a detailed inspection of the five overpasses on the south approach, in addition to the rope access inspection of the main section (Section 7) and Sections 3 and 6. In 2015, the inspection of Section 7 served as a reference for the lighting of the bridge for Montréal’s 375th anniversary.
Structura’s engineers supervised multi-beam ultrasonic surveys and prepared plans and estimates for repair work. Structura also assessed the load-carrying capacity of five overpasses in Section 1, the bicycle path in Section 9 and participated in the assessment of Sections 3, 6 and 7.
Assessment of the load-carrying capacity of the Des Sources footbridge
City of Pointe-Claire
Since 2017, Structura has been performing the annual inspection and monitoring of the Sources footbridge in Pointe-Claire. The bridge was built in the late 1960s and spans Highway 20 and the CN and CP railways.
Structura conducted an extensive damage survey using bucket trucks and rope access techniques. The load-carrying capacity assessment, achieved with 3D models, made it possible to issue recommendations and intervention scenarios to extend the footbridge’s life.
Design of the footbridge and lookout at Parc-nature de la Pointe-aux-Prairies
From 2012 to 2017, Structura assisted the Ville de Montréal in the design and construction of the footbridge and lookout at Parc-nature de la Pointe-aux-Prairies. The footbridge crosses a wetland rich in diversity and provides access to the birdwatching lookout.
In addition to contributing to the architectural concept, Structura also designed and detailed both structures. The design combines elements of sustainability and comfort with clean lines and aesthetics to blend harmoniously into the landscape. This project was a 2018 finalist for the Canadian Institute of Steel Construction (CISC) Awards of Excellence.
Assessment of the load-carrying capacity of the Matala Bridge Dam
In 2012, Structura performed a detailed inspection of the Matala Bridge Dam to assess its load-carrying capacity. The Matala Bridge is one of the main transportation links crossing the Cunene, a major Angolan river.
This type of structure is usually inspected using buckets, but transporting this equipment in this remote area of Angola was almost impossible. Access using the twin rope technique was thus favoured as the necessary equipment could be transported easily by plane. In four weeks, the team of six inspectors and rope access technicians completed a detailed inspection and dimensional survey of the structure’s 97 spans.
The mandate also included studying the behaviour of support devices and expansion joints, and issuing recommendations for maintenance and repair work
Survey of concrete pathology on the Skylon Tower
Niagara Falls, Ontario
In 2013, Structura’s team performed a survey on the Skylon Tower in Niagara as part Kärcher’s global project to demonstrate the quality of their products in extreme locations. Suspended at a height of 160 metres, Structura’s engineers performed a multitude of tests on the concrete to assess the structure’s condition.
