Project Details

Client: McGough Construction
Location: Minneapolis, MN
Services: Building Demolition, Earth Retention, Excavation, Site Utilities


The 37-story Gateway Tower has been a masterful display of Bolander’s dominance in the Twin Cities urban construction market.  This project utilized our full suite of capabilities and construction services to deliver the 55-ft deep excavation.

The project began with the installation of an H-Pile earth retention system followed quickly by the removal of over 130,000 cubic yards of rock and soil and the installation of 113 drilled piers extending an additional 48-ft deeper into rock.  To minimize disruption to the heavily trafficked Hennepin Avenue corridor, pipe jacking was elected as the least invasive way to connect site utilities into the city’s infrastructure.

“Extensive logistical planning was necessary to execute this project properly,” said Senior Project Manager John Caroon, “In addition to coordinating our work with other trades we also had to consider the city’s plans for the reconstruction of Hennepin Avenue and an adjacent tower, 270 Hennepin.”

The 22-story tower, 270 Hennepin, also became a Bolander project marking 2019 as the year Bolander teamed to change the skyline.
