What Inberg-miller Engineers does

Inberg-Miller Engineers (IME) is a privately held, multi-discipline engineering services firm headquartered in Riverton, Wyoming, founded in 1971. The firm provides civil, geotechnical, environmental, drilling, surveying, construction materials testing (CMT), special inspections, drone-based aerial mapping, and air knife (hydrovac) excavation services to government, commercial, energy, education, industrial, residential, communications, solid waste, community, and transportation clients across Wyoming and the broader Inter-Mountain West region. Its technical capabilities are anchored by in-house drilling equipment, modern accredited laboratories, AutoCAD-based design output, and a multidisciplinary staff of 65+ engineers, land surveyors, scientists, technicians, and administrative personnel holding professional licenses (P.E., P.G., L.S., CFedS, E.I.T.).

The company operates eight offices spanning Wyoming (Riverton HQ, Casper, Cheyenne, Gillette, Green River, Laramie), Colorado (Greeley), and New Mexico (Albuquerque), and holds accreditations from the US Army Corps of Engineers, WYDOT, AASHTO, the International Code Council, and ACEC. Revenue is generated through professional services billed on a project-by-project, quote-based model with multi-year contract cadence; pricing is not publicly disclosed and clients engage via direct sales, RFQ/RFP responses, SOQ downloads, and the QuestCDN public bidding portal. The GTM motion is relationship-driven enterprise field sales, with named recurring clients including the City of Casper (municipal), WSP USA Inc. (large engineering consultancy), and Coal Mountain Contracting (energy/mining). Key competitors would be other regional full-service AEC firms, while IME's competitive positioning rests on its 50-year regional reputation, breadth of in-house capabilities (drilling-to-CMT integration), and dense accreditation portfolio.
