Passing quality management system certification is a requirement of market competition, a requirement of scientific business management, a requirement of playing in the international market, and a symbol of a well-established quality management. In the beginning of 2003, our various responsible departments started preparing for ISO9001 Quality Management System Certification, carrying out all work in accordance with the standards under experts from Certification Consulting Company. Many audits were conducted by the third party. Our quality management system standards had completely met the international requirements so we successfully passed ISO9000:2000 Certification Upgrade and the external audit on ISO9001 Quality Management System. These certifications made us become a Grade-A General Contractor of Communication Engineering Construction of Zhejiang and the only construction company passing ISO9000:2000 Certification in Zhejiang.
