Twin Dur•A•Span Structural Aluminum Plate culverts were recently expedited through our Dorchester, NB facility to repair a washout that had closed Highway 144, near Edmundston.
AIL worked closely with the consultant and the owner, the New Brunswick Department of Transportation and Infrastructure (NBDTI), through the design phase of this project. NBDTI approved an immediate award on (date) but the materials needed to be on the job site by August 28. So we expedited raw material sourcing and delivery to our Dorchester plant whiles construction drawings were developed and approved quickly. Production of the step-beveled-end structures took only three weeks and the finished components were delivered on time.
Custom seam strengthening for extreme dead load
Lightweight and strong Dur•A•Span Aluminum was selected for this project due to the aggressive nature of the site’s soil. These structures had an 8 m cover height so a special seam strength design was required to handle the extreme dead load forces. The AIL Engineering Team developed a three-bolts-per-crest-and-valley seam-strengthening solution to accommodate the deep cover.
The project is still underway at time of writing and the client is pleased with the results to date. This is another good example of the Provincial Government calling on local engineering, manufacturing and construction partners to achieve their infrastructure replacement needs.
