Columbia Engineering Group

Columbia Engineering Group (commonly shortened to CEG) is a United States engineering firm that positions itself as an interdisciplinary, full-service provider of building and infrastructure engineering. According to its official website, the firm brings together mechanical, electrical, plumbing, structural, civil, and fire protection engineering under one roof, describing itself as "an interdisciplinary engineering firm providing Civil, Structural, Mechanical, Electrical, Plumbing, & Fire Protection, engineering services." The company markets this breadth as an "interdisciplinary edge," arguing that a holistic, multi-discipline approach lets it integrate solutions across disciplines and deliver better value to project stakeholders. CEG's service lines cover the core building-engineering disciplines. Its mechanical practice addresses HVAC system design for commercial, institutional, and governmental clients, including building automation, industrial ventilation, retrofits, renewable energy integration, and high-performance building design, supported by analysis services such as stress modeling, failure analysis, finite element analysis, life cycle cost analysis, thermal analysis, vibration analysis, fatigue analysis, and dynamic load analysis. Alongside mechanical work, the firm offers electrical, plumbing, civil, structural, and fire protection engineering, and it presents itself as a "one-stop shop" for clients who want a single firm to handle multiple disciplines. On the renewable and energy side, CEG highlights sustainable design work, including solar-powered vehicle charging stations, renewable generation, solar generation and transmission, hydro, renewable infrastructure, and EV charging. The firm frames this work around environmental stewardship and regulatory compliance, from conceptualization through implementation. CEG describes itself as a "certified veteran-owned and operated business," a status it presents as part of its identity and dedication to quality. Its leadership team includes principals Ty Nielson (Principal, CEO), Nate O'Neel (Principal, COO), Sean Kelly (Principal, CFO), and Steven Reed, PE (Principal, COO), supported by a bench of associate-level engineers across civil, structural, electrical, mechanical, and BIM roles, plus a project success team handling accounting, strategic partnerships, and executive support. The firm's project portfolio, as listed on its website, spans institutional, governmental, and utility work, with named examples including an FSU chiller replacement, the Eastern State Hospital Headquarters Building, a Department of Fish & Wildlife HVAC upgrade, the Milton-Freewater Armory, and the Gateway Substation in Richland, WA. Client testimonials on the site come from architecture and construction partners who praise CEG's professionalism, organization, attention to detail, and the convenience of having multiple engineering services in one place. CEG also publishes a monthly "Engineering Insights" news stream, with entries dated through 2025. The company is headquartered in the United States and operates primarily in the US market.

Columbia Engineering Group (CEG) is a United States engineering firm that has built its identity around interdisciplinary, full-service engineering.
