The services referred to include consultation, design surveys, feasibility studies, evaluation, planning, aesthetic and structural design, preliminary design, drawings, specifications, technical submissions, and other instruments of service, the administration of construction contracts, construction observation and inspection, and the coordination of any elements of technical submissions prepared by others, including professional engineers, landscape architects, and other consultants that pertain to the practice of architecture. A person shall be considered to be practicing architecture when such person uses the title "architect" or the terms "architect" or "architecture" or "architectural" alone or together with any words other than "landscape" to indicate or imply that such person is or holds himself or herself out to be an architect.
