Who is the father of tilt up?

• A. Robert Aikin
• B. Frank Lloyd Wright
• C. Le Corbusier
• D. I.M. Pei

Answer: (A)

The main idea here is identifying who is linked to the origin of tilt-up construction. Tilt-up involves casting wall panels on the ground and then lifting them into place with a crane, enabling fast, efficient assembly of large buildings. The person widely credited with starting and promoting this method is Robert Aikin. He helped demonstrate, refine, and popularize the process in its early days, shaping how tilt-up is used in practice today. The other well-known architects listed are famous for their design work, but they aren’t connected to originating tilt-up.
