Olsson continues its rapid climb up the list of America’s largest data center engineering firms.

We now rank No.7 on Building Design+Construction’s list of largest data center engineering firms. That honor marks an improvement from the previous firm-best No. 10 ranking released in 2024.

Olsson’s No. 7 position is based on revenue from data design services performed during the 2023 calendar year. Our rise has been meteoric; Olsson’s 2023 data center design revenue of $62.7 million marked a 64 percent increase from 2022 ($38.1 million).

“We strive to be the most technical, engaged, and responsive firm in the market,” Olsson Data Centers Sector Leader Brian Orton said. “We're engaged in what our clients need from engineers and designers, regardless of how our services have traditionally been structured. We can solve a lot more problems a lot faster this way.”   

BD+C shares information each year in its Giants 400 Report, casting light on the largest engineering, architecture, and construction firms in the U.S. More than 600 firms were part of the 2024 report, which included 137 sets of rankings across 25 building sectors and specialty categories.
