Acceptance and delivery of installation works, construction safety management, after-sales service of engineering projects, handling of customer complaints, training and assessment of employees, supervision of production and engineering quality, corrective and preventive measures, control of quality records, management of production and installation equipment, management of production and installation testing equipment, etc. It is procedural and may affect the implementation of personnel, materials, equipment, management and regulations.
(5) Establish a clear quality responsibility system.
ISO900 1 program documents strictly implement the quality responsibilities at all levels from the project chief commander to the operators, so as to ensure that the quality problems in the production process can be solved in time, without accumulation or delay, and the unqualified products in the previous process will never flow into the next process.
Third, the curtain wall quality assurance measures
(A) the quality management system
Establish a three-level management system under the direct leadership of the general manager of the company, directly controlled by the project manager and inspected by the quality inspection department at the grass-roots level, and form a vertical management line from the manager to the production and construction team, namely:
Quality Inspection Department of the Company (Summer)-Project Manager (Child)-Full-time Quality Inspector (Jin Shuguo)-Construction Team (Wang)
(2) Technical management measures

The design change procedure shall strictly implement the relevant provisions in the Quality Management Manual.
2) Check the construction
Summary of technical organization measures to ensure the quality of aluminum curtain wall project: quality management methods are compiled, and the self-inspection of construction personnel is combined with the first inspection and sampling inspection of professional quality inspectors during construction. Before construction, the technical director shall make technical disclosure to the on-site technicians.
The high-quality goods come from whether the technical requirements of the cleaning contract are consistent with the design. Proofread the construction details, recheck the completed building structure size before the main material is cut, and adjust the construction drawing size according to the measured size.
3) Before plate cutting, check the dimensions of the processing drawing of curtain wall components.
4) Prepare quality management methods, and combine the self-inspection of construction personnel with the first inspection and sampling inspection of professional quality inspectors during construction. Before construction, the technical director shall make technical disclosure to the on-site technical personnel, so that all construction personnel can make clear the technical quality requirements of the construction and installation of this project, and conduct self-inspection according to the contents of the division of construction work during construction, and the team leader will review it.
