What Henneman Engineering does

Henneman Engineering Inc. is a privately-held, multi-disciplinary engineering design and consulting firm headquartered in Champaign, Illinois, founded in 1961 by Ralph J. Henneman and now led by third-generation Chairman and CEO Laura H. French. The firm provides mechanical, electrical, plumbing, fire protection, structural, information technology, and sustainable/LEED design services for building projects, supplemented by an Industrial Technology Group (ITG) division that delivers process design, SCADA/HMI development, PLC programming, arc flash analysis, cogeneration design, and substation engineering for manufacturing, food and beverage, power and water, and renewable fuels clients.

The company operates through project-based professional services engagements, delivering integrated design from concept through construction administration using BIM and specialized modeling tools (ETAP, SKM). It holds Women Business Enterprise (WBE) certification, which channels it into diversity-procurement opportunities across federal, state, and municipal clients. Notable projects include the LEED Gold-certified Illinois State Capitol West Wing renovation, the LEED Silver-certified Village of Oswego Police Station, the LEED Gold-certified Killeen Police Department headquarters, the Illinois Executive Mansion restoration, and the Tomah Memorial Hospital in Wisconsin. Marketing relies on a project portfolio website, industry awards recognition, and direct client relationships rather than paid channels.

Henneman runs a sales-led GTM through direct engagement with government, healthcare, higher education, K-12, criminal justice, commercial, and industrial clients, operating from eight offices across Illinois, Wisconsin, and Florida. Revenue is generated through professional services fees on a project-by-project basis, with salary bands for technical staff in the $40K-$90K range indicating a cost structure typical of mid-sized regional engineering firms. The ownership remains within the Henneman family, with no external institutional investment evidenced.
