Only by realizing high-quality system construction can we provide a foundation for the effective operation of the security system and ensure that the system can play its due economic and social benefits. Therefore, the quality control of system engineering is very important. Only by implementing strict quality control can we truly achieve the goal of system quality construction and ensure the return on investment of system construction.

This system is formulated in order to ensure the implementation of the quality management system of our company, find anomalies in advance, improve the project quality rapidly, and ensure and improve the management and market demand.

First, the principle of quality control

1. Priority control principle

In the process of system construction, always adhere to the principle of quality control in advance, accurately understand the needs of users, and scientifically design information systems.

2. Standardization principle

In the process of system construction, we should design and build the system according to the characteristics of security system and relevant standards at home and abroad to ensure the scientific process.

3. The principle of meeting the needs of users

The completed system should meet the business function requirements and performance requirements of users. The degree of conformity with the user's needs can be judged by means of testing.

Two. Quality control process

Implementation of technical scheme for engineer's on-site inspection

Group self-inspection

Engineering department self-inspection

Company acceptance

Company's acceptance of important work procedures

Engineer acceptance

Three. Technical review

(1) Technical review shall be conducted for the construction organization design, and the content and place of the review shall be specified, and the reviewer shall use the review method.

(2) The results of technical review must be filled in the Record of Technical Review of Partial Engineering, and kept as the construction technical data.

Four. Examination and approval of construction organization design

1. The construction design must be signed by the technical department manager, project manager, project engineer, safety officer, material engineer and other relevant personnel.

2. The construction organization design must be submitted to the company's chief engineer for approval 15 days before the engineer implements it.

3. The construction organization design must be approved by all levels, and modified and improved according to the examination and approval opinions, and the construction can only be carried out after being reported for examination and approval.

4. During the construction period, the construction must be carried out according to the construction organization design. If there are any specific problems, they can be reported and handled according to the actual situation, but they must be approved by the chief engineer.

5. The construction organization design process:

Review design documents and conduct investigation and research.

Calculated engineering quantity

Choose the construction scheme and method.

Implementation of technical scheme for engineer's on-site inspection

Group self-inspection

Engineering department self-inspection

Company acceptance

Company's acceptance of important work procedures

Engineer acceptance

Five, material quality management

1. In order to strictly control the quality of purchased materials, the Quality Engineering Department must organize relevant personnel to conduct sampling inspection, and fill in the manufacturer, product name, specification, quantity, receipt number, etc. Inspection record of purchased materials.

2. If any problem is found, contact the supplier immediately and solve it through negotiation.

3, in the inspection, sampling should be random, can't be judged by personal or personal feelings.

4, completes the re-inspection of the material approach, request and support * * * to cooperate with the inspection, and record the inspection results.

Technology and quality disclosure of intransitive verbs

Technical and quality disclosure is an indispensable and important work content in the basic management of construction process, and the disclosure must be confirmed by a written visa.

1. After receiving the design drawings, the technical department must organize the employees of the technical department to study the drawings seriously, and urge the project owner to organize a design disclosure meeting.

2. After the preparation of the construction organization design is completed and submitted for approval and confirmation, the project leader of the technical department will organize all employees to study the construction plan seriously, and make written disclosure on technology, quality and safety, and list the key control parts and points.

3. Based on the principle of responsibility to people, safe work and quality assurance, each person in charge must make a written technical, quality and safety disclosure to the construction team when arranging construction tasks.

Seven, inspection and test equipment management

1. The engineering department shall have an inspection (test) equipment manager, who shall be responsible for the identification, supervision and management of the internal inspection and test equipment of the company.

2. On-site inspection and test equipment shall be kept and used by special personnel to avoid man-made damage.

3. equipment manager should make regular inspections to check the equipment maintenance, and record the results on the "Instrument Maintenance Card" to ensure the normal use of the equipment.

Eight, engineering and technical data management

1, the company's engineering data is divided into the following types:

One: technical management.

Category II: Construction technical data.

Three categories: construction organization design.

Four categories: construction management.

Five categories: quality management.

Six categories: maintenance category

2. The company has a full-time data administrator who regularly collects all kinds of data and forms provided by various departments and customer units, classifies and summarizes them, and reviews and binds them for verification.

3. The engineering department shall record the workload, labor force, machinery use, construction site, materials and equipment entering and leaving the site, quality problems, problems and remedial measures, etc. During the daily on-site construction, it will be submitted to the data manager regularly, who will summarize the construction diary and file it for the record.

Nine, visit maintenance, maintenance management

1. The construction team of the engineering department is responsible for product protection in the process of engineering construction. In the process of construction, the product damage caused by improper personal operation shall be borne by the individual and supervised by the engineering department.

2. After the delivery of the project (if it is delivered by stages, it will be counted from the date of delivery by stages), in terms of customer service, solicit users' opinions for a return visit.

3. After the project quality return visit (on call during the quality warranty period), the customer service center is responsible for solving the quality problems caused by the construction, leaving no hidden dangers, and registering the maintenance situation for future reference. If the customer requests maintenance for non-construction reasons, the customer service center will help solve it, and the expenses will be borne by the customer.

4. The customer shall sign and confirm all the projects maintained during the quality guarantee period.
