Multi-partner team keeps Maine crossing out of a Jam

November 29, 2012

Jam-Brook(web1)With a fish run expected in 10 weeks, time was of the essence when the contract was signed for the design, fabrication, delivery and installation of a crossing over Jam Brook in Searsmont, ME. 

Good communication was key

The AIL project team’s good communication practices were key to managing the efforts of several project partners: two owners, the consultant and three different fabricators. AIL’s engineering team designed the Super•Cor Arch and collaborated with the geotechnical consultant on the headwall and the MSE soil reinforcement solution for the headwall. 

Precast footings were essential for this fast-paced project 

Precast footings for the arch and leveling pads for the headwalls were supplied by a third-party precaster, which reduced the install time and habitat impact.

AIL offers a full range of stream crossing solutions

Depending on the size and nature of the crossing, we offer a variety of solutions in Ultra•Cor, Super•Cor, Bolt-A-Plate or Dur•A•Span Structural Plate. Corrosion/abrasion-resistant Dur•A•Span Structural Aluminum Plate is particularly well-suited to saltwater or aggressive environments. We can also provide specialized fish baffle inserts for some designs. Our open-bottom designs and Prefabricated Steel Bridges are effective, environmentally-friendly solutions to preserve habitat.
