ACS Group Ranks Among the Nation’s Top Engineering Firms in the 2026 Giants 400 Report
Each year, Building Design+Construction takes stock of the country’s largest architecture, engineering, and construction firms and publishes the results as the Giants 400 Report, the AEC industry’s annual ranking of the largest firms by revenue.
This year marks the survey’s 50th anniversary, and the field behind it is enormous: close to 600 firms took part, with final rankings spanning dozens of building sectors and six industry disciplines.
For the architects, developers, owners, and AHJs who read it, the report is a way to identify firms with real national scale and the capacity to deliver on the largest, most technically demanding work in the industry.
ACS Group, a national fire protection engineering and life safety consulting firm founded in 2020, ranks among the top 85 engineering firms in the nation — our first appearance on the Giants 400 Report.
It reflects a team that delivers, and clients and partners who continue to work with us on their most complex projects. We’re grateful to all of them and excited to keep growing.
