On-call Solid Waste Engineer

On-call Solid Waste Engineer

Gallatin County, MT

Project Features

When 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.
