Bolander is proud to be part of this landmark project that landed one of America’s finest soccer stadiums on a formally blighted St. Paul, MN parcel.  This remarkable urban revitalization presented numerous challenges to include soil remediation, discovery of abandoned structure and extensive connections to urban infrastructure.  Bolander stepped up to the accelerated schedule to support the creation of Allianz Field, the new home for Minnesota United in 2019.

Bolander provided the following work:

  • Mass excavation and export of over 250,000 CY of fill or silty soil
  • Import and placement of over 60,000 CY of clean sand
  • 240,000 SF of structural demolition
  • Temporary earth retention
  • Extensive groundwater management
  • Installation and tensioning of 124 structural anchors to resist uplift, up to 65’ deep
  • Stockholm soil tree trenches
  • Four storm water storage systems to include fused SRPE DuroMaxx
  • Two storm water lift stations linked to the City of St Paul management system
  • Fine grading and aggregates for approximately 23 acres
