Learning from the past
What other innovations lie buried in the historical record?
How often have the actions of past master builders, designers, and constructors anticipated our current construction practices?
What should universities be telling architecture and engineering students about their intellectual and professional heritage?
Can the understanding of our construction heritage encourage appreciation of modern construction practices?Can the understanding of our construction heritage promote new innovations?
