Turf Wars Between Design Professionals

As if architects and engineers did not have enough of their own problems in the form of liability suits, competition from contractors and the growth of design/build, the design professionals are now "at war" with other sectors of their own community.A few years ago the battleground involved architects and engineers, and focused on which profession had the legal right to design buildings.
