Behind Bergmann is Kelvin Manning, Kennedy associate director, technical. 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.
