Due to the particularity of the construction industry, the implementation of ISO 9001 quality management system by construction enterprises has the following characteristics:

    1. Instability of personnel. Construction enterprises often have both managers and skilled workers, as well as a large number of temporary workers and labor subcontractors. For personnel at all levels, qualifications should be determined according to their post status, and their abilities should be improved. Through training, on-site guidance and other means to improve the skills of construction personnel at all levels, only when the overall quality of the team is improved can the quality of the project be guaranteed.

    2. The indeterminacy of the place. Construction enterprises usually have several construction sites, and the construction work at each construction site must be carried out in accordance with a unified production system, operating standards, quality indicators, environmental protection requirements and safety management systems. For example, the inspection of materials and the monitoring of the construction process must be carried out in accordance with the prescribed requirements, and the construction log should be recorded.

    3. The complexity of the construction process. In the construction process, it is necessary to manage the five aspects of "man, machine, material, method and environment", which are also the main factors causing the quality of the project. In the course of the operation, if the phenomenon of cutting corners is found, it will be severely punished. The requirements specified in the design must be strictly implemented, such as the time for concrete mixing, which must be strictly followed.
