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 levelling pads for the headwalls were supplied by a third-party precaster, which reduced the install time and habitat impact.
Everything went swimmingly and the crossing was completed on time for the anticipated fish run.
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.
