Knobelsdorff Named Top-Performing Construction Company

This is the third year the company has earned this award from Associated Builders and Contractors

Knobelsdorff was ranked #89 on Associated Builders and Contractors (ABC) 2022 Top 200 Performers list, which ranks its commercial and industrial contractor members that build long-lasting high-quality construction projects, based on work hours.

Knobelsdorff also ranked #48 on the ABC’s Top 100 General Contractors in the U.S.

This is the third year Knobelsdorff has earned this award. Eligibility requirements for the top 100 general contractors include contractors that achieved STEP Gold or higher and earned ABC’s AQC credential in 2020, ranked by works hours.

“We are proud to be ranked in the top 200 performers and top 100 general contractor companies by ABC," says Karl von Knobelsdorff, CEO and president.

"Knobesdorff is grateful to be a part of many world-class organizations that focus on safety on and around the worksite while we GSD.”

As an ABC Top Performer, Knobelsdorff has demonstrated world-class safety performance by achieving platinum ranking in Safety Process Evaluation in ABC’s STEP Safety Management System, which makes the top-performing contractors more than six times safer than the U.S. Bureau of Labor Statistics industry average, according to ABC’s Safety Performance Report.

The listings highlight contractors that have earned ABC’s Accredited Quality Contractor credential for their commitment to corporate responsibility in quality, safety, talent management—including inclusion, diversity and equity — education and community relations; those that won national Excellence in Construction, Safety Excellence and Inclusion, Diversity and Equity Excellence awards; and those that hold designations awarded to diverse companies to help procure work from government and private entities.

Knobelsdorff has also received ABC’s Accredited Quality Contractor, Excellence in Construction, and Safety Excellence awards.

“Knobelsdorff invests in and attributes its successes to its people, and its value proposition gives their employees purpose, delivers quality to their clients, and strengthens their bottom line,” says Michael Bellaman, president and chief executive officer of ABC.

“Congratulations to Knobelsdorff for raising the bar in developing people, winning work, and delivering that work safely, ethically, and profitably.”
