Quality assurance system and control measures

the quality of the overall goal of project department to establish the quality checking system and improve the site regulation, strict implementation of the "three check" system (self inspection, mutual inspection, handover inspection), ensure the people-oriented, civilized construction, construction site clean and orderly, in strict accordance with the contract requirements, create quality engineering quality under the condition of.

2. of our quality assurance system has passed the quality system China Quality Management Association certification, awarded the certificate of quality management system, quality management system to meet the requirements of GB/T19001-2000 idtISO9001:2000 standard, according to the ISO9001 standard, according to the characteristics of the contract section of the project, will be the responsibility of the quality level decomposition into every employee, to strengthen every procedure, quality control of the whole process of full, in order to achieve the quality objectives.

3. quality assurance measures (1) project management department set up quality management leading group. Project manager takes part in group leader, chief engineer as deputy leader, quality engineer and professional engineer and functional department supervisor. (2) the construction team set up a quality management team, the leader of the construction team is the leader, the technical supervisor is the deputy leader, the head of the work group and the functional personnel of the team of w beam guardrail weight

the quality of education and training, the quality of education, improve the quality awareness, professional, standardized, before the start of operation requirements, the responsibility of training, each project construction personnel in regulating behavior, so that everyone understand the norms, norms, according to the standard construction, construction quality and everyone's interests clear. Do all the answers, to achieve scientific, standardized and standardized procedures for construction.

the implementation of total quality management, according to the characteristics of the contract section of the project, to set up the guardrail project which is subject to the QC group, the activities of research and implementation of quality control, the operation set of people, posts, positioning operation, ensure the engineering excellence times.
