Brierley Associates Visit Akkerman

Brierley’s Cottage Grove, MN team recently had the opportunity to tour Akkerman Inc.’s primary manufacturing facility in Brownsdale, MN. Alongside our partners at Barr Engineering, we explored the factory floor and gained firsthand insight into how Akkerman designs, builds, and maintains their broad range of trenchless equipment—including pilot tube, MTBM, TBM, and more—for clients nationwide and across the globe.

The tour featured TBMs in various stages of construction and assembly, from cutting steel plates to assembling digger shields. Our team also observed an MTBM that had just returned from the field for maintenance—fresh off a project in Oakdale, MN, where Brierley designed elliptical, shotcrete-supported shafts to support the contractor’s tunneling drives.

We also visited Akkerman’s Training and Development Grounds, where our staff had the chance to operate a pilot tube machine and experience the hands-on training they provide to contractors and industry professionals.
