Steel Substructure for Recreational / Pedestrian Bridge
Recreational bridge substructure design & details


As part of a complicated Joint Venture between a Designer, Fabricator, and General Contractor, Arch supplied engineering and drafting services to this complicated project.

This structure required being designed to be connected on top of an existing 100-year old decommissioned railway bridge.

Solution & Impact

Adequate assessment of the existing structure included metallurgical coupon testing, and high-definition drone survey, before designing a structure to meet AT and CSA codes. Welding methodologies and constructability were key to the success of the project.

Very tight timelines were met in order to achieve the manufacturing and fabrication schedule, with several just-in-time drawing packages made available to the workshops involved.
