The 37-story Gateway Tower has been a masterclass display of Bolander’s dominance in the Twin Cities urban construction market. This project utilized our full compliment 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. In addition to coordinating our work with other trades our project management team also had to take into account the city’s plans for the reconstruction of Hennepin Avenue and an adjacent tower, 270 Hennepin.
The aforementioned 22-story tower, 270 Hennepin, also became a Bolander project marking 2019 as the year Bolander teamed to change the skyline.
