Knife River – Yellowstone Division Uses HeavyJob & HeavyBid on McLaren Tailings
The McLaren Tailings Reclamation Project entailed reclaiming an abandoned gold mine mill tailings site adjacent to Yellowstone National Park. Due to the high elevation in the mountains, heavy snow limited the work season to only four months per year. Consequently, the project was started in June of 2010 and complete in September 2014. The general purpose of this project was to excavate 260,000 cubic yards of wet, soupy tailings laying up to 35 feet deep from behind the dam and stabilize (dry out) the tailings with quick lime prior to placing in an on-site repository. Upon completion of the work, it was extremely satisfying to everyone involved to see clear, sparkling water flowing through the site replacing the orange colored toxic water that had flowed for the past 80 years.
What makes it interesting?
The project is located at a high elevation (7200 feet) and is only five miles upstream from Yellowstone National Park. The tailings (waste material) generated during the milling process were contaminated with heavy metals that leached into adjacent Soda Butte Creek which then flowed directly into Yellowstone Park. The mill operated from 1934 to 1953 but had continued to contaminate Soda Butte Creek ever since. In 1960, Soda Butte Creek was designated the most polluted stream entering any national park.
How HCSS Software assisted with this project
HeavyBid was most effective in assembling a very complex bid with many subs and suppliers. There were three alternate bids that would have been very difficult to put together with out HeavyBid. HeavyJob was used from day one to project completion to track not only labor and equipment costs, but to track all truck deliveries (800 loads).
