2010 Completed Projects Archive
2010 Buechler/Velva Project
This project was designed to eliminate about 10,750 feet of dangerous highwalls on a 150 acre site at an abandoned mine southwest of Velva. Reclamation was to have been achieved by excavating material from spoil piles to backfill the highwalls and pits. Approximately 1,850,000 cubic yards of excavation were required for this project. Unfortunately the contractor, Smith Contracting of Butte, MT, ceased work and abandoned this project prior to completion. The project was completed under a tender agreement with Smith’s bonding company by Kern & Tabery, Inc. of Wadena, MN, September 30, 2011. The total amount paid to both contractors was approximately $1,447,264.80.
