About the Project

Farmers? Grain & Feed, LLC is a state-of-the-art feed mill and grain storage facility located on a 10-acre site in Allenton. Wondra Construction was the sitework and site utility contractor working directly with the owner. The building foundation work included excavation for a 50-foot by 60-foot basement, 18 feet deep, with a 4-foot thick floor. The area was adjacent to a wetland with artesian wells in the area and a water table 6 feet below grade. This required extensive and continuous dewatering. The high groundwater table produced a flowing slurry mix that was difficult to control. This required additional over-excavation and sloping of banks. The poor soils necessitated the use of a Topcon GPS-controlled excavator without an operator for safety. The high water table also prompted construction of a retention pond three times larger than the existing pond and the overall grades were raised by 3 feet, requiring the import of thousands of cubic yards of clean fill from a nearby quarry.
