Second, the supervision work summary
Within this year, the project supervision department completed the pre-acceptance of three links and one leveling, and subcontractors entered the site one after another, which put forward specific requirements for the preparatory work before the start of subcontracting projects and the management of project construction. After strictly examining the qualification of subcontractors, construction organization design scheme and preparation for commencement, according to the site conditions, commencement orders were issued one after another. In the follow-up construction, the project supervision department can strictly abide by the "law-abiding, honest, fair and scientific" supervision work criteria, carry out various supervision work according to the work contents, responsibilities and obligations stipulated in the supervision specifications and supervision contracts, and carry out various supervision work according to the laws, regulations, specifications, design documents and construction contracts of China Southern Power Grid, and achieved certain work results. The specific work of the project supervision department at the site is summarized as follows:
1, quality control work
In the quality control of this project, the main working method of the supervision project department is to strictly grasp the "three controls", that is, control before, during and after the event, and implement various control measures, so that the word "initiative" can be reflected everywhere in the supervision work, and good work results have been achieved.
1. In terms of prior control, the supervision project department mainly controls the input of materials, personnel and technology. First of all, the project supervision department has carried out strict inspection and acceptance of all building materials and equipment on site, and must conduct a second interview. All materials and equipment not approved by the supervision are not allowed to enter the site for use, so as to ensure that the building materials are genuine. In the whole construction process, all the raw materials and components that entered the site have undergone formal inspection, acceptance and re-inspection, effectively ensuring the quality of the project. Secondly, the on-site construction personnel, especially those in key positions, key jobs and key working procedures, were tried out. The construction personnel with poor technical level and weak sense of responsibility were strictly ordered to be dismissed and replaced by contractors, which greatly strengthened the quality assurance work before construction investment. Finally, the technology before the construction is put into use is well controlled. In this regard, the regulatory authorities take the initiative to give full play to their professional and technical advantages. According to the actual situation of the project, the construction technology, construction organization, foreseeable problems and quality acceptance requirements of important stages, key working procedures and key parts are detailed to the construction project department in advance, the important technical disclosure of the contractor is reviewed, and the technical disclosure is urged to be detailed, well done and implemented to ensure technical guidance.
2. In terms of process control, the project supervision department dynamically controls the site construction mainly through on-site inspection, patrol inspection and spot check. , in order to maintain the continuity of supervision quality control work, timely correct the quality problems and hidden dangers existing in the construction site, and ensure the implementation of various quality assurance measures. During the whole construction period of the main body of the project, the supervision department insisted on the on-site supervision of all earthwork backfilling and concrete pouring projects, effectively ensuring the construction quality of earthwork backfilling and concrete pouring. Through the efforts of the supervision department, it has played a great role in supervision and deterrence of on-site construction. During the whole construction period, there were very few illegal operations on site, and no major engineering accidents occurred.
3. In terms of post-event control, the project supervision department mainly adopts strict inspection and acceptance methods to control the project quality. For inspection lot projects that fail to meet the acceptance criteria, the contractor is strictly ordered to make rectification to ensure that the overall construction quality of the project meets the contract requirements. In addition, in order to strengthen the quality control of the whole construction process, the project supervision department not only requires the contractor to submit all inspection lots and inspection reports of concealed works on time, but also specially requires the contractor to submit process inspection reports in the order of subdivisional works, so that the quality control work of the supervision department can be refined to every link of construction, effectively ensuring the inherent quality of the project.
Through the strict control of the supervision department and the close cooperation of the contractor, the construction quality of the project has all reached the qualified standard after inspection and acceptance, and reached the goal required by the contract.
2, schedule control
In terms of schedule control, the project supervision department mainly takes the following measures:
1, according to the requirements of the total contract period and the actual situation of the project, through a detailed understanding of the contractor's personnel, materials, mobilization equipment and construction organization and management capabilities, fully considering the weather factors and human factors caused by the local social environment, we worked out a feasible total construction schedule with the contractor, and defined the time of several key construction stages. It is clearly required to complete the project in April this year. Through the overall grasp of the project progress, especially the strict control of several important construction stages, the site construction progress can be carried out quickly.
2. According to the total construction period plan, the contractor is strictly required to prepare the monthly schedule and weekly schedule on time, and the completion of weekly schedule will be strictly assessed at the weekly supervision meeting, and the opinions of the supervision department will be put forward for the preparation of next week's schedule.
3. In the specific work, according to the actual progress of the project at all times, on the premise of ensuring the goal of road hardening at the end of the year unchanged, adjust the schedule in time to make the plan as realistic as possible, change passive control into active control, and further concretize the supervision control work.
3, project investment control:
1, strictly check the engineering measurement, check the monthly progress output value declared by the contractor item by item, resolutely eliminate the false parts, and allocate the progress payment according to the facts.
2. Carefully digest the drawing design, thoroughly understand the design intent, communicate with the designer and the owner in advance for the problems existing in the design and the places that are easy to cause changes, strive for early changes, try to avoid changes afterwards, and reduce unnecessary waste and claims.
3. Strictly control the extra-budgetary expenditure, minimize the occurrence of out-of-contract quantities, and carefully verify the necessary out-of-contract quantities to ensure the correct use of project funds.
4, engineering safety control:
Safety control in building engineering is:
First, put an end to people's unsafe behavior, that is, organize construction in strict accordance with the rules and regulations to ensure personal safety and equipment safety;
The second is to put an end to the unsafe state of things, that is, the performance of the construction project itself should be safe and reliable, and the design intention of the project should be realized;
Third, realize civilized construction.
5, supervision project department contract management:
1, review the subcontracting qualification of subcontractors in strict accordance with the contract requirements, and put an end to illegal subcontracting.
2. Strictly supervise the contractor's performance of the contract commitments to ensure that the contractual obligations are faithfully performed.
3. Coordinate the cooperative relationship between contractors and subcontractors to ensure the smooth progress of construction.
6. Information management of supervision project department:
1, timely feedback all kinds of information on the construction site to the construction unit to ensure that the construction unit understands and grasps the construction dynamics.
2. Do a good job in collecting, sorting, keeping, handing over and filing all kinds of engineering construction materials to ensure the details and completeness of engineering construction materials.
3, to do a good job of sorting and sending internal information, to ensure that the project supervision department staff timely understand and master the engineering dynamics.

7. On-site coordination
On-site coordination is mainly to do a good job of coordination between the construction unit and the contractor, the contractor and the contractor, the construction site and the surrounding environment. Combined with the specific work such as schedule, quality and investment control, the whole project construction runs smoothly, the relationship is harmonious and the cooperation is close, which ensures the smooth realization of various objectives of the project construction.
8, 20 12 achievements and shortcomings of supervision.
In the past year, the supervision work has achieved certain results. First of all, the "three links and one leveling" of the substation was successfully completed. The project of the station area started smoothly, and the site foundation was basically completed. Generally speaking, about 70% of the engineering quantity of this line has been completed. The owner's project department is quite positive about our achievements.
There are also some shortcomings in this process. The overall progress of substation area construction is relatively behind the planned progress. In 20 12 years, Guangdong Power Grid Corporation deducted 0.3 points from the contractor's assessment, 0. 1 point from the substation in September, 0.4 points from the substation in June, 10, * * *: 0.2 points from the line in May, and 0./kloc from/0/0.
The achievements can be used for reference, and the shortcomings in the work need to be summarized and reflected. In the future work, the backbone will never make the same mistakes, so as to complete the future work more efficiently.
