Discussion on how to effectively manage the construction site through electrical supervision

The electrical supervision engineer supervises the project quality on behalf of the owner and is the bridge between the owner and the contractor. It not only requires practitioners to understand engineering knowledge and cost accounting, but also requires them to be very clear about building regulations. How to be a good site supervision engineer is very important in site management. China engineering supervision talent network, professional talent recruitment.

4.2.4 Review the project commencement application form and related materials submitted by the construction unit;

4.2.5 Attend the first site meeting hosted by the construction unit.

4.3 supervision methods in the construction stage.

4.3. 1 Formulate and implement the system of on-site regular meetings, and do a good job in handover inspection with civil works.

4.3.2 Working methods of engineering quality control.

1) requires the construction unit to submit the construction technology and quality assurance measures for key parts and key working procedures, and sign after approval;

2) Organize a special demonstration of the construction process measures and certification materials submitted by the construction unit for adopting new materials, new processes, new technologies and new equipment, and sign them after approval;

3) Review the application forms of engineering materials, purchased parts, equipment entering the site and their quality certification materials submitted by the construction unit;

4) Carry out parallel inspection or witness sampling for the physical objects entering the site according to the proportion specified in the supervision contract or relevant engineering quality management documents;

5) Refuse to sign the engineering materials, purchased parts and equipment that have not been accepted or qualified by the supervisor, and issue a notice to the supervision engineer to inform the construction unit to evacuate the unqualified engineering materials, purchased parts and equipment from the site within a time limit;

6) Regularly check the technical status of the metering equipment of the construction unit;

7) Patrol and inspect the construction process, supervise the hidden process of concealed works and the key parts that are difficult to check after the next working procedure is completed, and make measurement records;

8) Conduct on-site inspection on the concealed engineering application form and self-inspection results submitted by the construction unit, and sign those that meet the requirements;

9) Review the quality inspection and evaluation data of subdivisional work, and sign after meeting the requirements;

10) inform the supervision engineer of the quality defects in the construction process, rectify within a time limit and check the rectification results;

1 1) When major quality hidden dangers are found, which may cause quality accidents or have caused quality accidents, the chief supervision engineer shall issue a work stoppage order in time, requiring the construction unit to stop work for rectification. After the rectification is completed and the supervision engineer rechecks it, the director shall sign the report of returning to work in time.

12) For the quality accidents that need to be reworked or reinforced, follow up, check and accept the treatment process and results according to the determined treatment scheme.

4.3.3 Engineering safety supervision method.

1) Before the project starts, the project supervision department should hold a symposium on the safety construction of the supervised project to strengthen the in-depth study of safety knowledge and further strengthen the safety awareness of the supervisors.

2) The project supervision department shall formulate safety management responsibilities, implement the safety responsibility system, and implement the director responsibility system, with each professional supervision engineer taking his own responsibilities;

3) Review the safety management regulations in the construction organization design and the safety construction preparation in the starting conditions, otherwise, the construction shall not be started;

4) For the potential safety hazards existing in the construction process, it shall be ordered to stop work for rectification;

5) The supervision engineer shall conduct regular or irregular inspection or on-site supervision on the site, check the safety measures of the construction site and the office and living quarters, issue supervision rectification notice in time for the problems found, collect on-site safety information in time, and handle them in time;

6) Solve problems in safety construction through regular meetings and special meetings;

7) Report the engineering safety information to the owner through various channels in time;

8) Establish a safety construction status registration system, that is, accurately and timely record the safety status in supervision documents such as supervision diary, monthly supervision report and supervision work summary;

9) Establish a reward and punishment system for safety construction management, reward supervisors with excellent performance, and punish supervisors with weak sense of responsibility until they are transferred from supervision posts;

10) Check the safety production management responsibilities of the construction unit; Check the safety management organization chart of the project department of the construction unit; Check the safety assurance system elements and function allocation table of the construction unit; Check the post responsibility system for safety production of project personnel of the construction unit; The construction unit guarantee system elements and function allocation table;

1 1) Review whether there are specific measures to ensure the quality and safety of the project in the construction scheme or construction organization design, so as to meet the requirements of safe construction and supervise its implementation; Check the types and preparation procedures of construction organization design and special construction scheme, and whether the safety measures are reasonable and scientific;

12) Review the safety facilities of the construction unit to ensure that the materials, equipment and safety protection articles required for safety are in place;

13) Strengthen the safety management of subcontractors and check the safety management of subcontractors by the general contractor;

14) check and urge the construction unit to implement the safety protection measures of the division, subdivisional work or each working procedure and key parts according to the requirements of construction safety technical standards and specifications;
