We are thrilled to announce that the Minneapolis Central City Parallel Tunnel project has been named a Grand Winner at the 2025 ACEC/MN Engineering Excellence Awards! This transformative project enhances stormwater management in downtown Minneapolis, increasing capacity, reducing tunnel failure risks, and ensuring long-term resilience for the city’s infrastructure.
Sambatek’s Contributions:
As a key partner on this project, Sambatek provided essential support in several areas. We conducted the shaft siting study location report, identifying the best three access points for tunnel construction while minimizing utility impacts. Our team led the full tree inventory and survey for the portal site, developed all surface removal and restoration plans, and served as the CADD lead for the project’s plan sheets. We also finalized traffic control plans, collaborated on drainage junction structure designs, and performed traffic control and SWPPP inspections during construction to ensure compliance and safety.
