Gallatin County, Montana
On-call Solid Waste EngineerWhen Great West was hired in 2005 the Gallatin County Solid Waste District faced major challenges. The incoming tonnage nearly quadrupled from 30,000 tons/year to 115,000 tons/year. The existing scale facility and Master Plan for the construction of a 1.5 acre cell were inadequate for the major increase in tonnage. Great West assisted the District in the fast-track construction of a new scale/scale house facility, preparation of a new Master Plan and design of the Phase 3 cell. Over a 1.5 year period the District completed excavation of nearly 600,000 cubic years of material and constructed the lined cell. Great West has served as the on-call engineer for the District since 2005, completing numerous projects.
