Bob Clark has grown Clayco from a small St. Louis design-builder more than 30 years ago into an annual high performer on the ENR Top 400. In this ENR Exec Talk, he talks with Jeff Yoders and Aileen Cho about his Ride the Wave tour where he’s visiting all of Clayco’s job sites, how he founded the company on the premise of changing adversarial and antiquated processes, a bad call from OSHA on encouraging employees to get vaccinated and how far the industry still has to go to deliver the employee diversity results it needs.
