Project Spotlight: Broadway Subway Project
infraMOD supplied over 11,000 tons of fabricated and raw steel for Vancouver’s complex Broadway Subway Project.
SCOPE OF WORK
infraMOD was approached by Acciona-Ghella to provide a solution for design, supply, and delivery of a temporary traffic decking system.
infraMOD performed a variety of work for this project. The scope of the work included:
- Temporary Traffic Decks
- Steel Girders
- Walers
- Struts
- TBM Supports
- Gallow Beams
- Pipe & W Beam Piling
SOLUTION
This combination of planning, coordination and execution is integral to the success of a steel fabrication project to ensure accuracy and efficiency. This was the case with the Broadway Subway project. The innovative solution to maintain ground-level vehicular traffic during construction involved the installation of deck panels and transfer girders that would create a temporary road surface above the excavation. The structure will support the temporary road surfaces for the next 2 years while the subway construction is ongoing.
HIGHLIGHTS
infraMOD supplied 7000 tons of fabricated steel and an additional 4000 tons of raw material. Thanks to our relations with our steel mills, we were able to supply the raw piling material at a considerably lower cost than what our customer or the piling companies could purchase it for.
CHALLENGES
The city of Vancouver was extending one of its train lines and required a structural steel solution to maintain uninterrupted traffic flow while excavating various busy intersections along Broadway Avenue.
RESULT
- infraMOD is constantly innovating new systems and procedures to fabricate structural steel for complex structures and spent considerable time & planning for fabricating the structural steel.
- The final design and fabrication of structural components allowed for the timely installation of girders and deck panels under strict scheduled constraints for night shift work. The components were designed and installed with minimum field welding to reduce labor costs on site and allow for efficient disassembly after project completion.
- infraMOD worked in collaboration with the customer to achieve tight deadlines and budgets while managing ongoing design changes throughout the project.
