Why cant the Architect and Electrical Engineer on the project handle the design of the technologies in the presentation space?

Few architects or engineers have the specialized training required to properly engineer the technologies used in presentation systems. The continuing development of these technologies, the rapidly changing marketplace and the degree of continuing education required are significant. While the coordination required with other trades requires CDAI to have an understanding of the basic building trades, those trades require their own degrees of specialization and continuing education. In general, the training and experience needed to properly design technical systems is very different from and more specialized than the training and experience that most architects and engineers haveAt CDAI, trained specialists in audio, video, controls, lighting and acoustics analyze, design and fully engineer the technical systems and environments in conjunction with the project architects and engineers to achieve fully integrated systems and facility designs.
