Steel is utilized in the fabrication of bridge superstructures for different advantages: 100% recyclable, high resistance, light weight, etc. There are several steel grades on the market today. At the design stage, when it comes to choosing the steel grade for different members of a bridge, the designer must consider several parameters. This article aims to discuss a few. Weldability In steel bridges, the weldability of the steel used is one of the most important parameters. The weldability can be defined as the ease to which quality welds can be performed. The most current index used to qualify the weldability is the…
Special collaborator : Jean Fournier, P.Eng. The Sherbrooke University has decided to commit to the construction of a 600kW solar park in order to study the various technologies of PV solar panels and structures currently available on the market, except for CPV panels. The project includes for fixed solar panels installed on the ground and on the roof of the sports center, as well as solar trackers on the ground capable of tracking the sun on two electric motor axes. Solar panels installed on the roof of the sport center will supply the University’s facilities while those installed on the ground…
The submerged arc welding process (SAW) is used to fuse metal pieces by producing an electric arc between an electrode wire with continuous wire feed and a base metal. The electric arc is produced beneath a layer of granular flux which is laid down on the joint to be welded. The flux protects the fusion bath against the oxidizing ambient atmosphere. It also eliminates the welding…

In this third episode, you will see the fabrication management through the eyes of the production team. The urgency of the project, the tight schedule, the Lean approach and the flawless quality control are…
For over three years now, Canam-Bridges has been using the Lean method, based on Toyota’s production system, as a manufacturing strategy. The Lean approach is based on the elimination of waste within production processes. It results in lower stocks and production time as well as better quality, less damage and obsolescence, and greater flexibility thanks to processes being better organized. The goal…
Canam-Bridges is proud to present the second video clip from its webseries entitled “Connecting the Shorelines” which will focus on the fabrication of the components of the new Champlain Bridge. Our experience in this project has enabled us to significantly improve efficiency, increase speed, and eliminate waste. In this second episode, you will learn how we embraced the Lean culture as well…
Canam-Bridges is proud to present the first video clip from a webseries entitled “Connecting the Shorelines” which will focus on the fabrication of the components of the new Champlain Bridge. The first episode presents the advantages and challenges of design-build construction in addition to the management of four teams totaling 50 drafters, in four locations. The webseries will include a total of four video clips…
The Muskrat Falls Project is a large-scale hydroelectric dam initiative undertaken by the province of Newfoundland and Labrador. A critical step in the process was the construction of a 377-feet (115-metre) long, 750-ton temporary bridge in the city of Goose Bay. The bridge, which is 52 feet (15.85 metres) wide and 30 feet (9.14 metres) high, is mainly used by vehicles known as off-highway trucks…
It’s a brand-new year, so naturally, everyone’s aflutter with visions of svelte waistlines, getting organized, spending more time with friends and family, and spending less/saving more. I’m not a resolution guy, but over the past few weeks, I’ve spent a great deal of time deciding what to change for this upcoming year, and figuring out how I’m actually going to do it (don’t fail me…
Canam-Bridges just supplied seismic isolators for two overpasses located at the Félix Leclerc (Highway 40) and Laurentian (Highway 73) interchange in Quebec City, Quebec. As part of this project, two overpass ramps underwent repairs while two bridges were demolished and rebuilt. The structures were designed by a consortium composed of BPR and EXP, and the project was carried out by EBC Construction on behalf…
Special collaboration: WSP Canada Inc. This temporary bypass bridge was fabricated by Canam-Bridges as part of the project to replace the Île-des-Sœurs bridge, which serves as the gateway to the new Champlain Bridge. This bypass bridge is a 541 foot (165 meters) long causeway. The structure was built to limit the impact on traffic during the reconstruction of the permanent Île-des-Sœurs bridge, which will…
The Hastings movable bridge, located in the Village of Hastings, Ontario, Canada, needed major repairs. The structure is a 2,200 square foot (204 square meter) swing bridge. In 2016, Canam-Bridges replaced its 83.8 foot (25.6 meters) long by 26.7 foot (8.2 meters) wide superstructure. Hastings Swing Bridge under construction Challenges The weight of the new bridge superstructure and deck had to be low enough for the existing mechanical…
