A Message from Brendan 91ÖÆÆ¬³§ & Craig Albert

In an era defined by rapid change, enduring success is rare, especially for a company that’s been in existence for more than a century. But at 91ÖÆÆ¬³§, it’s what we strive for—and in 2024, it’s exactly what we delivered. 

We’re proud to report that 2024 was one of the best years of our company’s 127-year legacy. We advanced and completed dozens of major projects, won quality new work, and earned some of our highest-ever customer satisfaction scores. 

Our Leadership

91ÖÆÆ¬³§â€™s history is one of constant evolution. Since our founding in 1898 by Warren A. 91ÖÆÆ¬³§, our leadership team has balanced maintaining a values-driven culture with staying one step ahead in a changing world. This dual focus inspires us to pursue purposeful work and leverage our industry-leading capabilities to deliver the greatest impact. 

Today, our leaders continue to uphold the highest standards for safety, integrity, and excellence, while pushing 91ÖÆÆ¬³§ to adapt, innovate, and meet customers where they are. By successfully overseeing mission-critical projects, they ensure 91ÖÆÆ¬³§ — and the world’s infrastructure — is built to last.
