First, both engineers and technicians and architectural design need a certain culture, but architectural design needs a higher culture, such as mechanics, building codes and computer knowledge.

Second, both engineers and architects need to obtain certificates. For example, builder's certificate, safety officer's certificate, quality engineer's certificate, structural engineer's certificate, architect's certificate, etc. But in contrast, it is easier to get a technician's license, and it is mainly to spend money, plus your own understanding.

Three, engineering and technical personnel are mainly on the construction site, the risk is the quality and safety risk, the most important is the safety risk, if something goes wrong, they will go to jail and bear criminal responsibility. Architectural design is generally not so risky, because design is to sit in the office and design with a computer.

Fourth, as a starting point, the engineering and technical personnel are a little lower, and the architectural design is much higher. Generally, the graduate degree or above, at least the bachelor degree or above.
