The architectural technologist, also known as a building technologist, provides technical building design services and is trained in architectural technology, building technical design and construction. Architectural technologists apply the science of architecture and typically concentrate on the technology of building, design technology and construction. The training of an architectural technologist concentrates on the ever-increasingly complex technical aspects in a building project, but matters of aesthetics, space, light and circulation are also involved within the technical design, leading the professional to assume decisions which are also non-technical. They can or may negotiate the construction project, and manage the process from conception through to completion, typically focusing on the technical aspects of a building project. Most architectural technologists are employed in architectural and engineering firms, or with municipal authorities; but many provide independent professional services directly to clients, although restricted by law in some countries. Others work in product development or sales with manufacturers. In Britain, Ireland, Sweden, Denmark, Hong-Kong (Chartered Architectural Technologist), Canada (Architectural Technologist or Registered Building Technologist), Argentina (M.M.O Maestro Mayor de Obras / Chartered Architecture & Building Science Technologist) and other nations, they have many abilities which are extremely useful in a technological sense to work alongside architects, engineers and other professionals - the training of a technologist provides skills in building and architectural technology. It is an important role in the current building climate. Architectural technologists may be directors or shareholders of an architectural firm (where permitted by the jurisdiction and legal structure). To become an Architectural Technologist, a four-year degree (or equivalent) in Architectural Technology (in Canada normally a three year diploma) is required, which can be followed by a Master's Degree, with structured professional and occupational experience. By country Canada Most provinces in Canada have an association representing Architectural Technologists and Technicians. In the province of Ontario, the Association of Architectural Technologists of Ontario (AATO) was founded in 1969. The Association holds four titles, Architectural Technologist, Registered Building Technologist, Architectural Technician and Registered Building Technician and the French equivalent of each title. The Association recognizes students and has an Internship process for members that incorporates both education and work experience for members. Our membership is involved in all aspects of the construction industry and often form part of the team of professionals on all types of projects.
