Our Projects

Office Buildings

Plymouth City Hall & Public Safety Facility

  • Plymouth, MN
  • 70,000 SF

About This Project

Combining the public safety department and the city hall unified the government complex. The secured squad parking garage is built into the natural bowl-shaped site, reserving additional park area and providing a necessary security separation of police and staff vehicles. This project had extensive concrete and masonry work. 


Addition and Renovation

About This Project

The Green Bay Packaging project included the addition of a break/lunch room area, conference room space for the sales team to meet with clients, a display space, training room, design and printing area, testing space, flexible office space, and a major addition of manufacturing and storage space. This large-scale project occurred while the facility remained fully operational so the company didn’t miss a beat during construction.
