"Build it twice, once virtually in the computer and then physically in the real world" is an approach that is gradually gaining appeal among architects and structural engineers.
The Architecture, Engineering and Construction (AEC) industry is often considered to be a late adopter of modern information technologies. Part of the reason may be that each architectural or civil work is a single unique "product", and therefore the benefits of automating certain design procedures may not be that rewarding as in the other engineering industries, such as automotive and mechanical, where many identical physical pieces are manufactured from a single design. But things may have started changing recently.
