Another 100 Years The Central City Parallel Storm Tunnel Project addressed a critical issue of a growing and developing city. Minneapolis’ 100-year-old storm drain system has been cracking under the growing pressure that comes with an increasingly popular area. The new storm drain system built by PCiRoads with the help of Curb Roller Manufacturing equipment aims to provide the city of Minneapolis with 100 more years of sturdy underground infrastructure.
Curb Roller Manufacturing’s equipment fits this need by allowing operators to work upright rather than being hunched over like they would be if they used manual methods for the same work. The machines also provide operators with a small learning curve, so crews remain productive even if they’re shorthanded or inexperienced. While the custom drum is designed for tackling the tunnel invert, there are some areas of the tunnel project where the concrete is mainly flat with a small grade and the custom tool isn’t required. After tackling these labor-intensive zones with manual labor to start, PCiRoads again sought an innovative, efficient solution that’s less strenuous than screeding the concrete with a 2x4. This led PCiRoads to invest in a Batt Screed from Curb Roller Manufacturing. The lightweight, battery-powered roller screed operates with no cords, hoses, or fumes, providing unparalleled jobsite mobility. Its three-position handle allows for ergonomic operation. “We have a great tunnel crew and these machines have been great for taking less of a toll on the guys,” Clover said. “The Batt Screed has been phenomenal. I wish I had one right away for this project. In fact, I wish I had one 10 years ago.”
