Heart of the City

Project Details

Client: Kraus Anderson
Location: Rochester, MN
Services: Building Demolition, Earth Retention, Excavation, Site Utilities

Overview

Heart of the City, true to its name, is nestled between the Mayo Clinic, and Rochester’s flagship hotels, and restaurants.  Given the sensitive nature of this project the city of Rochester and Destination Medical Center entrusted Bolander with a Best Value contract to deliver their vision while limiting the impact on Mayo Clinic patient traffic and patrons of surrounding businesses.

In pursuit of this challenging work, Bolander proposed a plan that would maintain water and sanitary services to businesses throughout the duration of the project.  This plan maximized passive flow bypasses, quiet electrical pumps and buried temporary water services to separate the business operations from our below grade reconstruct of the city’s utility infrastructure.  Always pushing to innovate, Bolander utilized a Rock Trenching machine to trench 600-ft of soil and rock in depths in excess of 19-ft.

The project has also become the heart of our company’s Rochester operations.  Currently the project is home to our new Rochester utility crew led by Shawn Erlanson and employs three quarters of our total Rochester workforce.  Thanks to our hard-working crews putting in long hours we are expecting to substantially complete this project one month ahead of schedule.

Heartland Trail

Project Details

Client: MN DNR
Location: Frazee, MN
Services: Building Demolition, Earth Retention, Excavation, Site Utilities

Overview

This Minnesota Department of Natural Resources project is a link in the new state trail system between Detroit Lakes, MN and Frazee, MN. In the process, Bolander stabilized a 40’ tall slope directly between Acorn Lake and Highway 10. Accessing this job was no easy task; prior to starting, Bolander designed a temporary access road along the lake which allowed issuance of a MnDNR work in waters permit. Once the trees were cleared and the access road installed, we worked along the lake shore to install a 440′ long sheet pile wall which was later enhanced

with over 100 tie-back anchors. Flanking the sheet pile were two big-block retaining walls, each over 200′ long. Above the trail, on the upper part of the steep slope, Bolander installed over 2500 percussion anchors in a large reinforced zone. Throughout the duration of the project, Bolander moved no less than 25,000 CY of soil and installed numerous storm water structures. Finally, the trail itself was paved, the site seeded and landscaped – now ready to connect visitors with the outdoors.

Minneapolis Bus Garage

Project Details

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

Overview

With 3,055 driven piling – equal to around 63 miles of pipe – the Minneapolis Bus Garage is the largest driven piling project in Bolander’s history! To meet the strict pile batter specifications, Bolander made a capital investment purchasing a crane-mounted fixed leads system with GPS technology; we are the first company in Minnesota to own and operate this piece of equipment.

Fixed leads increase pile driving productivity by minimizing the movement of the crane, decreasing the time spent placing the pile under the hammer, and monitoring pile depth and plumbness in real time.

The new 550,000-square-foot garage is planned for an 11-acre site northwest of Target Field adjacent to the existing Heywood garage and Metro Transit’s headquarters. This facility is integral to the Met Council’s transit plan and has been designed to store and maintain 216 long rapid electrical buses – improving the accessibility of public transportation in the metro area.

RBC Gateway Tower

Location: Minneapolis, MN

Overview

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.
