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

Overview

In Fall of 2022, Knutson Construction award the Xcel Energy Chestnut Service Center to Bolander.  Our scopes of work include Building Demolition, Earth Retention, Excavation, & Site Utilities.  The sequence of our work needed to be structured in a manner to allow Xcel Energy to maintain its current operation at this facility.  This was a significant challenge due to the limited space on site.

This first phase of the project consisted of the partial demolition of the annex building and associated site work.  The annex building remodel had to be completed to allow Xcel to utilize this facility before the project could move on to the next phase of work.  Bolander & Knutson were able to deliver the remodeled annex building ahead of schedule.

We are now actively working on the final phase of the project.  This phase of work began with the demolition of the existing main office building.  This building had a footprint of over 80,000 square feet and was over 60 feet high in some areas making this one of the biggest building demolition projects in Bolander history!  Bolander safely brought this building down on schedule.  To remove the building foundation, we had to install a significant driven H-Pile & Lagging Earth Retention System in sequence with the building demolition.  Our Deep Foundations and Demolition personnel were able to work collectively to achieve this common goal.

After being awarded this project, we were informed that the soils on this project were contaminated.  Some of the areas on the site contained soils that contained hazardous levels of PCBs.  Thanks to training and certifications obtained by our Bolander team members, we were able to work with Xcel and Knutson Construction to safely export this material from the project.

This project is another fine example showcasing the multiple talents of the men and women of Bolander and what can be accomplished when we all work together!
