Section 4 Project Quality Management Guarantee Measures
1. Guarantee Measures for Construction Progress Plan
In the project engineering, our company will appoint project managers with many years of rich experience and ability and various professional engineering engineers to form the project management department. Professional construction personnel also select personnel with rich experience in construction experience. In terms of funds and materials, the company will give the greatest support, and will implement special funds for this project without any compromise, and equip the project with various types of construction machinery and equipment with advanced performance. Measuring instruments and equipment, inspection and testing equipment.
2. Technical guarantee
Before construction, formulate various construction plans and technical disclosures. The coverage of the construction plan should be comprehensive and the content should be detailed, accompanied by charts, pictures and texts. To take the initiative to mobilize the enthusiasm of the operation layer to learn the construction plan, the construction method combining flow construction and parallel construction is adopted in the construction. Various advanced construction technologies and construction techniques are used to compress and adjust the duration of the construction process on a flow section to ensure that the entire project duration can be shortened.
3. Construction materials and equipment admission plan
The admission time of materials and equipment during construction shall be proposed by the relevant personnel of the project management department in advance according to the construction plan and the actual situation of the site. So that material purchasers or equipment suppliers are ready to transport spare materials to the site to ensure smooth and on-time completion.
The construction captain must lead the team to do the following tasks: adhere to the construction according to the drawings, strictly implement the acceptance specifications, and unify the construction according to the quality inspection and evaluation standards, and take effective measures to remedy the quality problems, so as not to leave behind. Do a good job in quality inspection of each process and make records. If the previous process is unqualified, the construction of the next process cannot be carried out, and the quality is strictly controlled. All staff participate in quality management, and each staff member must ensure the quality of his own work and be responsible for the quality of his own work. All testing tools during construction must be inspected, tested and measured before construction, and measuring instruments of unmeasured measuring tools are not allowed to be brought into the site. Strict quality inspection system, implement quality one-vote veto and punishment for common quality problems, establish a quality assurance system headed by the project manager, and improve various rules and regulations. On site, after entering the site, care should be taken to keep the materials to avoid unnecessary damage. If the construction personnel find unqualified materials during the construction process, it is forbidden to use them. Construction personnel at all levels shall strictly implement the established installation quality standards, and shall not lower the installation quality standards on their own with the permission of the project manager. Pay attention to the acceptance of various concealed projects. Before concealment, it must be signed by the owner, the supervisor and the professional engineer before concealment. Strengthen group activities, carry out quality competition activities, regularly carry out technical quality training for various types of work, and improve the technical level of construction personnel.

2. Management organization
(1) The establishment of the "Safety Production Management Committee" headed by the person in charge of production safety of the project management department and attended by persons in charge of production safety of each construction unit organizes and leads the production safety management work at the construction site.
(2) The main person in charge of the project management department and the person in charge of each construction unit sign a letter of responsibility for production safety, so that the responsibility for production safety is assigned to each person and responsible for each level.
3. Management system
(1) Every project must set up a regular work meeting of the "Safety Production Management Committee", so that there is mobilization before the project, implementation of the project, and summary after the project.
(2) In organizing the construction, it must be ensured that the construction personnel of the project team must have the person in charge of the project on duty at the site, and must not be vacant and out of control.

When changing the scheme and measures, it should be implemented after being approved and signed by the leader of the technical competent department of the original design scheme, otherwise no one may change the scheme and measures without authorization.
(4) Establish and implement a safety production technology disclosure system. It is required that each construction project must have a written safety technical disclosure, the safety technical disclosure must be targeted, and the disclosure must be signed by the person to be disclosed.
(5) Establish and implement a safety production inspection system. The project management department organizes a joint inspection every half month with the participation of the safety production leaders of all construction units. If major unsafe hidden dangers are found, the inspection team has the right to issue a shutdown order, and the construction can be started after the hidden dangers are eliminated and approved by the inspection team. .
(6) Establish an acceptance system for mechanical equipment, temporary power facilities and various scaffolding projects after failure. It is strictly forbidden to use without acceptance and unqualified acceptance.
4. Behavior control
(1) Personnel entering the construction site must wear safety clothing, otherwise it will be regarded as illegal.
