Dick Bergmann, far left, original lead designer for the Vehicle Assembly Building (VAB); and Phil Moyer, fourth from left, original project lead for the VAB, tour the iconic facility at Kennedy Space Center in Florida with descendants of Max Urbahn, the original architect, on Nov. 22, 2019. The Florida Section American Society of Civil Engineers bestowed its National Historic Civil Engineering Landmark award to the facility. The VAB is the first building at Kennedy Space Center to earn this distinction. At the time of its completion, the 129-million-cubic-foot structure was the largest building in the world. Originally designed and built to accommodate the Saturn V/Apollo used in Project Apollo, the VAB was later modified for its role in the Space Shuttle Program.
