Three SEH projects earned engineering excellence honors during the American Council of Engineering Companies of Minnesota’s (ACEC-MN) 55th Annual Engineering Excellence Awards Gala at the Landmark Center in downtown St. Paul on February 25, 2022.
SEH received Grand Award honors for the Detroit Lakes Wastewater Treatment Facility Project in Detroit Lakes and the Trunk Highway 246 and Jefferson Parkway Reconstruction in Northfield. The Crystal Airport Runway 14R/32L and Taxiway Echo Modifications Project received an Honor Award.
ACEC-MN’s Awards Program recognizes engineering achievements that “exhibit the highest degree of merit and ingenuity.” Entries were judged by an objective panel based on the following factors:
Congratulations to the project teams and clients for this well-deserved recognition!
Client: Detroit Lakes Public Utilities
Finding the best solution for any given challenge has more variables than a generation ago. We have a responsibility to plan infrastructure that positively impacts citizens – and the world.
The City of Detroit Lakes had a 60-year-old wastewater treatment facility and needed to reduce the phosphorous entering a local lake, Lake St. Claire, by 94%. By embracing innovation, the SEH project team planned, designed and constructed a $30 million improved treatment system that includes a membrane bioreactor (MBR) to physically separate solids. Now, the facility meets one of the most stringent phosphorus limits in Minnesota – with operating costs lower than anyone anticipated.
Client: City of Northfield
Northfield’s community pride is so evident when it comes to this safe, new intersection. The partnership we built helped this amazing roundabout come to light. There’s more to come, too, when the tunnels and paths link up with the regional trail.
SEH worked with the City of Northfield to transform a busy and unsafe four-way stop near local schools into a roundabout with multimodal tunnels that feature brightly painted murals. Using the City’s Safe Routes to School Plan, the team assessed multiple options and conducted in-depth public outreach before deciding on this roundabout configuration. The SEH team made sure the community remained top of mind during construction, as access remained open, and construction was completed in a single season.
Client: Metropolitan Airports Commission
Improving safety was the overarching factor in so many aspects of this project. It’s exciting to think that Crystal Airport’s users and operations will benefit for years to come.
As one of the state’s busiest airports that serves as a reliever to Minnesota’s largest airport, Crystal Airport needed to remain in use throughout this major reconstruction that would impact the entire airfield. Safety for all users was the driving force for the updates that included converting an existing runway into a full-length parallel taxiway, minimizing runway incursion hotspots and upgrading electrical to improve navigation at night. The SEH team’s complex phasing plan allowed aircraft use throughout construction.
