Reston, Va. — The American Society of Civil Engineers (ASCE) today announced its 2024 class of Distinguished Members, awarding eleven distinguished and active members with the highest honor ASCE can bestow. Out of ASCE’s more than 160,000 active members, only 264 in history hold the status of distinguished member. This honor is reserved for those who have attained eminence within the realm of engineering, whether that be construction, related arts and sciences, or engineering education. ASCE inducts a new class of distinguished members annually.

“Our distinguished members have made monumental contributions to the civil engineering profession throughout their careers, but perhaps most importantly, they have dedicated their time to advancing the knowledge of the next generation of professionals,” said ASCE President Marsia Geldert-Murphey, P.E. “Increasingly severe weather events and changes to the infrastructure ecosystem require engineers to find innovative solutions which break the mold. I am proud to welcome the 2024 class of distinguished members, each of whom have pushed boundaries throughout their career, demonstrating the forward-thinking philosophy required to improve the livelihoods of all Americans.”
