Who can give a weak electricity construction program model

(I), pre-construction preparation

1, familiarize and review construction drawings and related technical information

1.1, whether the construction drawings are complete, complete, and whether the presentation of the drawings comply with the requirements of the relevant national or regional standards and norms;

1.2, whether the construction drawings and the building The site in the plane size, elevation, pipeline layout and other aspects of consistency;

1.3, construction drawings and text description of the content of the consistency, as well as construction drawings and the consistency of the professional part of the construction drawings;

1.4, professional and technical personnel should read and familiarize themselves with the content of the construction drawings and the requirements of the questions and problems to the design institute. Organize them to be solved one by one when the design institute technical submission;

1.5, according to the requirements of materials, technology and construction difficulty in the construction drawings, verify whether the existing construction technology and management ability can meet the schedule and quality requirements, and formulate the corresponding measures.

2, construction technicians of the technical briefing

2.1, construction technicians must hold an electrician's license to work on the job;

2.2, all construction technicians before entering the field must be technical briefing before starting, and familiar with the construction drawings;

3, construction progress plan arrangement

3.1, synchronized with the civil construction progress, in strict accordance with the requirements of the construction process and steps;

3.2, according to the company's construction progress reasonable co-ordination of the project schedule;

3.3, the implementation of the construction of water and electricity barge to the location;

3.4, the implementation of material transportation routes, stacking sites, material processing sites in place;

3.5, according to the drawings and site requirements, verify the warehouse materials, equipment in place, and verify acceptance of whether it is consistent with the design and quality requirements, and found that the quality of the problem in a timely manner to request the replacement of the lack of equipment and auxiliary materials in a timely manner to put forward the procurement of the place;

4, construction personnel planning arrangements

Staffing according to the construction progress and goals, reasonable arrangements for the entire construction period of management personnel, technicians, installers, the number of people and the work cycle, to achieve a clear division of labor, the responsibility of the person, so that the supervision, control, construction operations of all aspects of the close combination of the organization of the construction of a strong construction team, in stages. Timing and quantitative quality and quantity to complete the construction tasks; to avoid unnecessary waste of labor, reduce project costs.

(2), construction procedures

The overall principle of the installation of this project is: first underground and then on the ground, the first big and then the small, the first complex and then simple. First key parts, after the secondary parts; pipeline laying order first high and then low, first trunk after the branch; first no pressure after the general principle of pressure.

Based on the specifics of the project, the electrical construction is divided into with the pre-embedded stage, installation and with the combination of pre-embedded stage, rough construction stage, with the decorative stage, the power commissioning of the five phases, according to the installation of the distribution system, the installation of the distribution box, the installation of the cable tray, the electrical piping and pipe threading, cable laying, wiring and trial operation of electrical equipment, lighting fixtures, such as the terminal Electrical installation, lightning protection and grounding part of the installation and other aspects of construction deployment.

(C), sub-parts of the project construction program
