structural engineers and the wall movers to use the new floor slabs and underlying soil to support the cribbing for the move. The system consisted of a 12-inch thick layer of gravel placed on the over exca- vated subgrade followed by a single layer of Mirafi HP370 geotextile. Another 2-foot thick layer of gravel was placed over the geotextile and floor slabs cast on that material. Over the course of six hours on August 13, International Chimney Corp., with support from Expert House Movers and structural engi- neering consultants Pierce Engineers Inc., completed the wall move flawlessly in a series of seven five-foot jack extensions in between which the systems were re-set to keep the wall moving to its ultimate destination. In case you’re wondering just how carefully the move was executed, that’s equal to 0.00114 miles per hour. At the end of the move, the total settlement was less than half of what the structural engineer specified. With the new 3,500-square-foot space created by the wall’s move now being enclosed and finished, the MSO is looking forward to its first performance in the new space around this time next fall. For everyone at GZA, C.D. Smith Construction, International Chimney, Pierce En- gineers, and Expert House Movers who worked on this one-of-a-kind project, that will be some especially sweet music to enjoy.

Instead of adding complexity to a job with many moving parts, GZA made use of what was already there. The company’s geotechnical engineers designed a ground improvement process that allowed the

Next Stop: Brewhalla’s Open Doors Door manufacturer helps transform a train maintenance building into a beautiful brewery
Conversations buzz and beer flows from the tap. In the distance, a train roars past. The train’s presence is subtle and fleeting, but not lack- ing significance. After all, the building that’s now home to a brewery and taproom spent its early years as a locomotive maintenance facility. Brewhalla is one of Fargo, North Dakota’s latest breweries, and it’s located in a building that’s older than the state itself. Named in honor of their Scandinavian heritage, the team at Drekker Brewing Company opened Brewhalla—its second location—in September 2018. With features heavily influenced by the building’s history and an entrance flanked with sizeable picturesque custom doors, the structure now appears breathtaking and effortless, but the road getting there was anything but.
