What an awesome week in Las Vegas at CONEXPO‑CON/AGG (last month!)
Another outstanding year of learning, connecting, and seeing where our industry is headed. A huge thank‑you to our president for continually pushing education and growth—it makes all the difference. We’re grateful to be part of such an important industry, and we truly believe construction and the trades are one of the best career paths for today’s youth—especially as the skills gap grows and AI reshapes the workforce. Proud of our team and excited for what’s ahead.

Another Great one lost. Our thoughts and prayers are with The Friaufs and Rinderknecht Family.

It is with heavy hearts that we share the passing of Gerry Friauf, who served as President of Rinderknecht Associates from 1999 to 2002. Gerry's leadership, vision, and dedication to our company left an indelible mark, shaping the strong foundation we continue to build upon today.

Beyond his professional accomplishments spanning 39 years with Rinderknecht, Gerry was a cherished colleague, mentor, and friend to so many. His legacy of excellence and integrity will always be remembered within the walls of Rinderknecht Associates and throughout our community.

We extend our deepest condolences to Gerry's family, friends, and former coworkers during this difficult time. Our thoughts are especially with his son, Scott Friauf, our current CEO, as well as the entire Friauf family.

Rest in peace, Gerry. Your impact will be felt for generations to come.

His impact lives on ❤️🤍

One year ago today, we lost a valued member of our team, Joe Fay, who passed away unexpectedly. Joe was more than a Vice President and Project Manager—he was a dedicated colleague, a trusted mentor, and a friend to so many. His legacy lives on through the relationships he built with clients, coworkers, and friends, as well as in the many projects throughout our community that he helped bring to life.

Joe’s impact continues to inspire us every day. We hold his family in our hearts and honor his memory as we reflect on the lasting mark he made on our company and the community we serve. He is missed but never forgotten.
