The murky water required a precise method of measuring the cuts as debris was removed. By removing the wood waste and building a small island in the Grassy Point area, the DNR hopes to restore the damaged habitat. MAE began digging out vast amounts of wood waste that had rested at the bottom of the river for more than a century, when sawmills lined the waterfront. Midwest Amphibious Equipment (MAE) tackled the huge restoration project, equipping two of its amphibious excavators with Topcon HiPer VR, an FC-5000 field controller and an X-53i system.
The Minnesota Department of Natural Resources (DNR) led the effort to remediate a section of the St. They’ve found that the ability to “see” beneath the surface with their machines has proven invaluable in improving efficiency and minimizing the risk of over/under cutting. Over the years, contractors involved in underwater excavation projects - dredging, pond/lake expansions, creation of boat landings, waterfront cleanups, etc. - have become some of the most ardent supporters of GNSS-based solutions.
