What Hatzel and Buehler, Inc does

Hatzel and Buehler, Inc. (H&B) is a privately held, unionized commercial electrical contractor founded in 1884 in New York City and now headquartered in Wilmington, Delaware. The company delivers full-service electrical design, construction, engineering, integration, and maintenance for large-scale healthcare, pharmaceutical/biotech, higher education, industrial/manufacturing, financial services, data center, commercial, and government projects across 11+ states (DE, MD, NJ, NY, PA, OH, MI, VA, WV, KY, DC). It claims the distinction of being the oldest electrical contractor in the United States and the longest continuous member of the National Electrical Contractors Association (NECA, since 1901), with an affiliated International Brotherhood of Electrical Workers (IBEW) workforce.

The company's core offering is project-based electrical construction — utility duct banks, medium-voltage switchgear, unit substations, lighting, fire alarm, security, AV, data/communications, and medical equipment installation — delivered through preconstruction services, integrated project delivery (IPD), and dedicated design-assist capabilities. It operates a vertically integrated technology stack built around in-house VDC/BIM modeling (Revit, eVolve Electrical, Navisworks, Autodesk Construction Cloud), Trimble X7 3D scanning, engineering tools (ETAP, AGI 32, Polywater, Visual), and 100,000+ sq ft of prefabrication space across 13 fabrication facilities. Under its 'Power of One' initiative, H&B bundles its core electrical scope with two wholly-owned subsidiaries: Bluestone Communications (low-voltage/technology) and Blue Sky Controls (building automation).

H&B monetizes exclusively through direct enterprise field sales — competitive bids and negotiated contracts on a project-by-project basis — with no disclosed recurring revenue, channel partners, or franchise model. Marquee clients span decades-long relationships with Johnson & Johnson (since 1979), Penn Medicine, AstraZeneca, Northwell Health, CHOP, Nemours, INOVA, Comcast, Wells Fargo, JPMorgan Chase, Verizon, AT&T, Boeing, BASF, Marathon Petroleum, University of Michigan, and the United Nations. Operational scale includes 1,001–5,000 employees, 4,061,984 man-hours worked in 2025, an EMR of 0.815 (vs. industry 1.0), DART of 0.20 (vs. 1.1), and TRIR of 0.74 (vs. 1.8), and 20+ in-house BCSP-certified safety professionals.
