The Montana Department of Transportation (MDT) was plagued with 9 shallow and deeper-seated landslides at six sites throughout the eastern two-thirds of the state. In order to repair the sites quickly, effectively, and at the least cost, MDT put out a design/build solicitation to repair the sites.
GeoStabilization International® teamed with Great West Engineering out of Helena, MT. The team scored highest on both the Statement of Qualifications and the technical score, and, most importantly, came in $2.8 million dollars under the next responsive bidder. After award, GeoStabilization allocated up to 5 crews working concurrently to ensure the project was completed on time. Our equipment experts designed and built special grout plants that could keep working in the sub-zero temperatures of Montana’s “spring.” MDT, impressed with the work as it progressed, added a seventh site to the list during construction.
GeoStabilization finished all seven sites before the original six-site deadline. As usual, no contractor initiated change orders were made, with the only change in scope being those requested by MDT. Our crews installed a total of 1,800 SuperNails™, 32,000 square feet of galvanized high strength mesh, and 21,000 square feet of shotcrete. Each of these projects is supported by GeoStabilization’s industry-leading Multi-Year Performance Warranty.
In the Mid-Atlantic Region of the United States a rockslide occurred that presented a variety of problems for the state’s Department of Transportation (DOT).
