1.2 compilation instructions

The organization and implementation of engineering construction is the key to the success or failure of the whole project. Only by making a feasible scheme before the project and implementing it in the project to realize high-quality safe production can we provide users with a high-quality system that meets the current needs, and should provide the greatest convenience and save money as much as possible for future maintenance and upgrading.

XXXX believes that a complete engineering process consists of design, business, construction, commissioning, acceptance, completion and maintenance. Therefore, a complete project organization and implementation plan should fully consider the above links, not only to arrange the progress, quality and safety of construction links, commissioning links and acceptance links, but also to organize the management of design links, business links and completion links, formulate the progress plan and promotion, quality management and control of each link, and finally arrange and implement the maintenance plan.

The project implementation of weak current system is a comprehensive and coordinated management work, which needs the cooperation of civil engineering, hydropower, HVAC, air conditioning and decoration, and its core is effective management. As the engineering design and project construction manager of positioning weak current system, XXXXX Company has ISO900 1 certification, introduced the international advanced Six Sigma management concept, adhered to the enterprise concept of "people-oriented, * * * common development", and trained and introduced a group of mature technical designers and project managers after years of practical engineering training. At the same time, we will continue to explore the project implementation mode, set up a "joint fleet" with overall operation, and realize the transformation from the practical engineering mode designed and installed by our company to the intelligent mode of continuously strengthening our own technical strength, quality assurance system and export project management mode, so as to control the project cost, flexibly integrate the organization, and implement the management concept of XXXX in the complete weak current system project.

XXXX Company's mission: to constantly exceed the growing needs of customers.
