On August 29, 2020, construction project audit experts appointed by China Classification Society Certification Company arrived at the Kangda Leping Project Department accompanied by personnel from the Group's General Department, aiming to conduct an on-site audit for the under-construction PPP project of the comprehensive inland river treatment project in Leping according to the three system certification standards. The manager of the Leping project Yao Yungang, the construction worker Ma Hongwei, the safety officer Li Hua and other personnel of the Project Department actively cooperated with the audit. After a two-day rigorous on-site data review and field survey of the project, experts checked a large number of basic data and records of the construction process, and timely communicated with personnel of the Project Department on the technical problems existing in the construction process, which greatly benefited personnel of the Project Department. In general, the on-site system of the Kangda EP's project under construction is running well. The project construction is in compliance with GB50430 standards and QES management systems, namely the ISO9001 quality system, ISO14001 environment management system, occupational health and safety system. No serious nonconformities are found during the audit, but there is still some work that needs to be improved in time, such as the timely validation of testing instruments.
