UniField executed its first mineral and metals projects in the Northern Rockies, when precious and base metals extraction was still wide-spread in the U.S. In that environment, UniField developed significant expertise in process facilities design for mines, mills, leach circuits and flotation plants, nonferrous and light metals smelters, and hydrometallurgical refineries. As the overall industry moved off-shore, UniField followed by providing specialized process expertise in cyanide recovery and hot metal handling to clients in South and Central America, Asia, Europe and Canada. We continue to provide studies, preliminary and detailed engineering, as well as procurement and construction administration, to a similar array of owners though with the addition of specialty minerals and metal forming clients.

First and foremost, UniField is a process facility engineering firm that is focused on delivering optimum return on client investment. Owners rely on our thorough and accurate studies and cost estimating to assist them in annual capital and major project budgeting. Our engineers are well versed in the latest equipment designs, process modeling tools, regulatory mandates and safety standards. UniField’s full-service staff has the experience and ability to complete all facets of process, electrical, mechanical and civil/structural design of small projects as well as major plant expansions and green field installations.

In addition to engineers and designers, we have a complete staff of procurement, scheduling and construction administration specialists - enabling UniField to assume full engineering responsibility for your project through startup. On major projects, our typical contracting approach is as the owner’s EPCM agent, wherein UniField holds engineering responsibility for the project from study through startup, commissioning and acceptance testing. For small capital projects, we most often team with the owner’s staff to achieve a flexible, low-cost delivery.
