Technical institutes are usually national or international in scope. Each is recognized as the preeminent forum for exchanging information and as the principal body of knowledge for the industry it serves. National technical institutes facilitate the exchange of knowledge between many different industry stakeholders, including subject matter experts, academics, designers, contractors, owners, code officials, fabricators, erectors, and manufacturers. With well-organized membership bases and a focus on collaboration and dissemination of information, technical institutes provide a framework that independent industry organizations cannot. While any number of associations may serve an industry for a variety of professional and economic reasons, there is only one technical institute. When one industry overlaps with, or is a subset of, another, the technical institutes involved typically have well-established collaborative relationships with one another to effectively combine their bodies of knowledge. Technical institutes are not developed overnight; establishing expertise, standard-setting authority, and a reputation for reliability takes time, often decades.
