Joseph A. “Bud” Ahearn, 81—who headed major military building programs as a U.S. Air Force major general, was vice chairman of design-builder CH2M and was a founding sponsor of global pro bono building group Engineers Without Borders, which now has 19,000 volunteers—died July 11 in Greenwood Village, Colo., of natural causes.
A University of Notre Dame engineering graduate with 34 years of military service, he managed major global base construction and operation and helped develop the service’s first environmental compliance programs.
