In order to further improve the quality management level of construction enterprises, provide high-quality buildings for the society, and meet the professional needs of quality management in the field of construction, The National Certification and Accreditation Administration and the Ministry of Housing and Urban-Rural Development decided to apply the "Quality Management Standards for Engineering Construction Enterprises" (GB/T50430:2007) in the quality management system certification in the field of construction. The certification standards for engineering construction enterprises to obtain certification certificates should be GB/T19001-2008/ISO9001:2008 and GB/T50430:2007. The "Quality Management Code for Engineering Construction Enterprises" is a recommended national standard issued on October 23, 2007, and officially implemented on March 1, 2008. It is the first national standard about the quality management of engineering construction enterprises. Relative to technical standards and technical specifications, it is also the first management specification about the quality management of construction enterprises.

Since January 1, 2011, in the field of engineering construction quality management system certification, in accordance with the "Quality management system requirements" (GB/T19001-2008) and GB/T50430:2007 "Quality Management standards for Engineering construction enterprises" to carry out certification activities.

Second, construction enterprises engaged in construction activities shall implement all the requirements of the "Quality Management Code for Engineering Construction Enterprises", encourage the use of qualified third-party certification, the content of the certification should include the "quality management system requirements" and "GB/T50430:2007" "Quality Management Code for Engineering Construction Enterprises" requirements, The authorities will take the results more seriously.

Third, since January 1, 2011, all certification bodies in China to the construction enterprise quality management system certification, should be in accordance with the "quality management system requirements" and "GB/T50430:2007" Construction Enterprise Quality Management standards "to carry out certification audit activities.

4. China National Accreditation Center for Conformity Assessment shall revise the accreditation requirements for the professional scope of construction in accordance with the requirements of GB/T50430:2007 "Quality Management Standards for Engineering Construction Enterprises", and re-evaluate and confirm the certification bodies with the professional scope of construction from September 1, 2010. Those who meet the conditions will continue to be granted corresponding accreditation qualifications.

5. After re-approval, the certification body with the professional scope of construction recognition has obtained the quality management system certification in accordance with the "Quality management system requirements" standard, at the expiration of the renewal of the certificate, it should add the "GB/T50430:2007" "Quality Management standards for Engineering Construction Enterprises" requirements to complete the conversion of certification; The certificates that are not converted within the time limit are invalid, and the certification body shall deal with the invalid certificates accordingly.

6, in accordance with the "quality management system requirements" and GB/T50430:2007 "Engineering construction Enterprise quality Management standards" implementation of the certification activities, certification certificate certification standards should be :GB/T19001-2008/ISO9001:2008 and GB/T50430:2007.

7, according to ISO9001:2008 "Quality Management system requirements" and GB/T50430:2007 "Engineering construction enterprise quality Management standards" implementation of certification activities, It can still be combined with GB/T24001/ISO14001 environmental management system and GB/T28001/OHSAS18001 occupational health and safety management system to establish an integrated management system of quality, environment and occupational health and safety.

The promulgation of GB/T50430:2007 "Quality Management Standards for Engineering construction enterprises" aims to further strengthen and implement quality responsibility by promoting the full implementation of construction enterprises, improve the level of enterprise self-discipline and quality management, and promote the scientific, standardized and legalized quality management of construction enterprises. As the first management standard for the quality management of construction enterprises, the "Quality management Code for Engineering Construction Enterprises" has the characteristics of advanced nature, guidance and flexibility, which are specifically manifested in:

1) The basic idea of GB/T50430:2007 is consistent with the ISO9000 series standards, and fully covers the requirements of ISO9001 standards in content;

2)GB/T50430:2007 fully embodies the characteristics of construction enterprise management activities in the structure of the provisions, highlighting the process method and PDCA thought;

3)GB/T50430:2007 combined with the characteristics of construction industry management, on the basis of ISO9001 standards and put forward many further requirements;

4)GB/T50430:2007 localization, industry characteristics, concise and clear language, easy to implement;

5)GB/T50430:2007 is consistent with the current management mode of the construction industry in China, and the construction enterprise will not increase the burden when implementing, but reduce the formal operation caused by the misunderstanding of the enterprise ISO9000 standard, and reduce the burden.

6)GB/T50430:2007 closely combines the requirements of the current construction management laws and regulations issued in China, so as to promote the process of legalization of project construction management through the implementation of the specification;

7) The preparation of GB/T50430:2007 is not from the narrow "quality" perspective, only limited to engineering (product) quality control, but from the perspective of all quality behaviors related to engineering quality, that is, the concept of "high quality", which fully covers all quality management activities of enterprises;

8)GB/T50430:2007 is the basic requirements for quality management of construction enterprises, and is not the highest level of quality management of enterprises. Therefore, at the same time of ISO50430:2007, enterprises are encouraged to carry out management innovation according to the needs of their own development, such as the implementation of excellent performance model, so as to enhance the competitiveness of enterprises.
