Stephen E. Sandherr, who has led the Associated General Contractors of America since 1996, is retiring next spring. He will be succeeded as CEO by Jeffrey D. Shoaf, the chief operating officer. AGC announced the changes Oct. 30, and said they will take effect March 31.

AGC has 89 chapters and more than 27,000 member firms. Shoaf, 59, has been in its second-ranking position since 2017. He joined the group in 1994 to lead its government relations activities. Earlier, Shoaf was on staff at the House Transportation and Infrastructure Committee.
