A, weak current construction management

Weak current engineering construction is a comprehensive management work, the key lies in its coordination and organization function, and also includes the management contents of other professions. Its main contents are as follows:

1. Progress management of weak current construction

The progress management of weak current construction determines the organization of construction personnel, the supply of equipment, and the timing of cooperation between weak current project and civil engineering and decoration project during the whole construction period. Usually, it must be checked and managed by establishing a project schedule. The preparation of weak current construction schedule is based on the construction sequence, which mainly includes the following stages, namely, building installation drawing design (deepening secondary design), pipeline construction, equipment (incoming goods) acceptance, equipment installation, debugging, initial opening and acceptance.

The work in each stage of weak current construction is as follows:

1) field installation stage

(1) civil engineering coordination stage: floor holes and wall holes are reserved according to the embedded parts required by various systems marked on the civil engineering professional drawings, and concealed pipes are embedded according to the plane pipeline laying drawings of various weak current projects. (2) Mechanical and electrical equipment installation stage: laying open wires such as bridge, main pipe and branch pipe according to the plane pipeline laying diagram of each system. (3) The weak current construction team shall make technical disclosure for the electromechanical equipment installation unit of the civil special construction unit, cooperate with the on-site installation, and negotiate with the electromechanical equipment supplier for technical connection. (4) The civil construction unit shall provide the weak current construction team with the hydropower conditions needed for construction, and provide a working platform for working at heights. (5) The supplier of mechanical and electrical equipment shall provide technical documents and drawings such as the reserved measuring point position and connector specifications of the mechanical and electrical equipment body, the principle and wiring mode of components entering each system, the principle of intelligent equipment, communication interface, etc., and undertake technical cooperation. (6) The design unit shall be responsible for the design modification during weak current construction.

2) Debugging stage

(1) debugging of weak current system software before entering the site. (2) The alignment of weak current system hardware before entering the site. (3) Control the monomer adjustment of weak current equipment. (4) Cold calibration of software and hardware in weak current engineering site. (5) Debugging of weak current subsystem. (6) The electromechanical equipment installation unit shall cooperate with the on-site debugging personnel of the subsystem to complete the debugging work.

2. Weak current construction interface management

The units involved in weak current construction mainly include weak current general contractor, weak current subsystem subcontractor and weak current construction company. It is also very important to coordinate with the owner, installation supervisor, weak current supervisor (supervisor), decoration contractor and construction contractor in the construction process.

The central content of construction interface management is the division and coordination of weak current system engineering construction, electromechanical equipment installation engineering and decoration engineering construction in its engineering construction content interface. In particular, there are many interfaces between intelligent building management system and electromechanical equipment and independent subsystems. Generally, it is managed by the way of dispatching meetings of project leaders of each subsystem, and a document reporting system is established. All measures are recorded, modified and coordinated in writing.

3. Organization and management of weak current construction

Reasonably arrange the number of weak current project managers, technicians, installation workers and commissioning engineers during the whole weak current construction period and the time for these personnel to enter the site, so as to avoid unnecessary labor waste and increase labor costs. This kind of management needs to be closely combined with the construction schedule management, and the strong and weak electricity construction teams should be organized in stages to complete the construction tasks at this stage on time with good quality and quantity.

4. Weak current construction site safety management

Safety is more important than Mount Tai. Strictly carry out, implement and enforce the relevant provisions and measures of the Building Law of People's Republic of China (PRC), the Environmental Protection Law of People's Republic of China (PRC), the Labor Law of People's Republic of China (PRC), the Regulations on the Administration of Work Safety in Construction Projects and the Regulations on the Safety Inspection of Building Construction, so as to ensure the safety of the weak current construction team in the construction process.

In addition to meeting the above weak current construction management, weak current construction should also focus on the following work:

(1) Strengthen the coordination between majors and types of work.

Weak current engineering involves civil engineering, decoration, air conditioning, water supply and drainage, power supply, lighting, elevators and other majors. In a sense, weak current engineering is a collaborative type of work, and it must be closely coordinated with the above professions at the project site, especially the coordination of valves, water pipe temperature sensors, flowmeters, water flow switch and its installation, opening position, boss welding, and baffle and actuator.

(2), strengthen the inspection and acceptance between processes.

Because the installation and debugging of pipelines, lines, trunking and line laying equipment in weak current engineering may be carried out by different construction units, after each working procedure or type of work is completed, corresponding construction records or installation forms must be filled in. The installation, threading and wiring of single equipment must be carried out in accordance with the requirements of concealed engineering and corresponding engineering acceptance specifications and design drawings, and the test records of single equipment should be made well, and relatively complete engineering technical files should be submitted to ensure the engineering quality and prevent wrangling.

Second, the engineering technology management

1. Management of technical standards and specifications

Weak current engineering should be carefully checked in system design, provision and installation, and the whole management should be controlled according to relevant standards and norms. There are many technical standards and specifications of countries or industries in weak current engineering design, which must be strictly observed. According to the contract and design requirements, the engineering interfaces between weak current systems, subsystems and electromechanical equipment, civil engineering and decoration specialties, the determination of engineering scope and responsibility interfaces among product suppliers, engineering contractors and construction units, and the modification, adjustment and reconfirmation of these engineering interfaces during the project implementation.

2. Installation process management

Weak current engineering is a highly technical work. To do a good job in the technical management of the whole weak current project, it is mainly to master the technical conditions of installation equipment and the technical requirements of installation technology in each construction stage. On-site engineering and technical personnel should strictly check, and record any situation that is inconsistent with the specifications and design documents or the contents that have been modified at the site during weak current construction, so as to establish technical management files and materials for the final overall debugging and opening of the system.

3. Technical document management

Weak current engineering technical documents are the same basis for the implementation of the project at all stages. These folders mainly include weak current construction drawings, design descriptions, relevant technical standards, product manuals, subsystem debugging outlines, acceptance specifications, and weak current engineering acceptance standards. These technical documents need systematic and scientific management. In order to provide complete and correct technical documents to engineering managers in time, rules and regulations such as sending and receiving, copying, modifying, submitting, keeping, borrowing and keeping secret of technical documents have been established, and effective science has been implemented.

Third, the project quality management

The quality management of weak current engineering is a comprehensive reflection of the work of weak current engineering units in buildings. The implementation of ISO900 1 system engineering quality system should run through the whole project implementation process of weak current system, and the following quality links should be truly grasped:

1. weak current construction drawing standardization and drawing quality standard;

2. Quality inspection and supervision of pipeline weak current construction;

3. Review wiring specifications and quality requirements;

4. Quality inspection and supervision of wiring weak current construction;

5. Quality inspection and supervision of field equipment or front-end equipment;
