KANSAS CITY, Missouri — Burns & McDonnell maintained its No. 7 ranking on Engineering News-Record’s (ENR) 2026 Top 500 Design Firms list, marking its ninth consecutive year among the Top 10.

In 2025, the 100% employee-owned engineering and construction firm reported $8.6 billion in revenue and contributed to more than 25,000 projects worldwide, with continued momentum in data centers and electrical infrastructure.

“Across the industries we serve, demand for infrastructure is accelerating at an unprecedented pace, while the ability to deliver is increasingly constrained,” says Leslie M. Duke, chair and CEO of Burns & McDonnell. “Clients need fully integrated solutions bringing power, transmission, site development and construction together into a coordinated approach. The ability to serve clients across the ecosystem — and deliver with speed, flexibility and reliability — is where we are focused every day.”

Published annually, ENR’s Top 500 Design Firms list ranks companies based on revenue for design services performed in the previous year.

No. 1 in Power for the 11th consecutive year, the firm also ranks among the top 20 design firms in multiple market sectors:

• No. 3 in Telecommunications
• No. 4 in Industrial Process/Oil & Gas
• No. 9 in Manufacturing
• No. 19 in Sewer and Waste
• No. 19 in Hazardous Waste

Burns & McDonnell ranks No. 20 among designers in international markets.
