CSG Consulting Engineers

“It would be well if engineering were less generally thought of, and even defined, as the art of constructing. In a certain important sense it is rather the art of not construction or, to define it rudely, but not inaptly, it is the art of doing well with one dollar, which any bungler can do with two after a fashion.”

Arthur Mellon Wellington, 1847-1895
Economic Theory of Art of Railway Location (1887)
