IDAD architects and designers are responsible for the planning and development of all aspects of land/water interfaces that relate to resort, sport and destination development, including marine, riparian and freshwater bodies. This polyspecialized field is concerned with human/water interactions, resort, travel, tourism and hospitality issues at inland, landfall, near-shore and offshore sites. Such architects use recreational, theatrical and entertainment design knowledge together with legal, scientific and engineering requirements to assess prudent planning and design decisions. IDAD architects may be involved in hospitality projects, resorts, theme parks and exotic destinations. In addition, they may design for travel and tourism projects, or be involved in watercourse, shoreline and basin protection and coastal engineering. They may apply their skills to the research of new attractions and systems such as floating structures, ports-o'-call, onboard resorts and meltwater attractions.
