GB / T 50430 "code for quality management of engineering construction enterprises" is a management standard established by the Ministry of housing and urban rural development of the people's Republic of China to strengthen the quality management of engineering construction enterprises. The instability of the construction quality and the nonstandard management of the enterprise cause the frequent safety accidents of the construction enterprise, and at the same time bring many development hidden dangers. In this context, the GB / T 50430 standard came into being after being negotiated and drafted by the national certification and accreditation supervision and Administration Commission and the Ministry of housing and urban rural development.          

This standard makes requirements for a series of processes such as project bidding, signing of construction contract, construction site survey, construction drawing design, preparation of construction related operation instructions, mobilization of man-machine materials, construction process management and construction process inspection, internal completion acceptance, completion delivery acceptance, file transfer personnel departure, warranty service, etc. of construction enterprises, and promotes standardized management of enterprises, So that construction enterprises can meet the needs of quality management in the field of construction, create conditions for further strengthening and implementing quality responsibility, and further promote the long-term stability and development of enterprises.
