At present, science and technology have penetrated into various fields, and intelligence has gradually become the main component of life. With the maturity and development of building electrical and building intelligence, science and technology have been integrated into life, intelligence has changed life, and the building industry has been endowed with new vitality. However, the rapid development must be based on quality and safety, otherwise, once an accident occurs, not only will the life experience be greatly reduced, but also the loss will be incalculable. In this paper, the causes of engineering safety and quality problems in building electrical and intelligent are analyzed, and the corresponding solutions are put forward, in order to improve the engineering safety and quality of building electrical and intelligent and promote the steady development of building electrical and intelligent engineering.
