So, do you know anything about job summary? The following is a summary of the project supervision work at the end of the year that I helped you sort out (selected 5 articles) for your reference, hoping to help friends in need.

Year-end Summary of Project Supervision 1 I. Project Overview

Suqian Rongmin Sanatorium Ward Complex Building Project is located at the intersection of Xingfu North Road and Zhangzhuang Road in Suqian City. It was built by Suqian Rongmin Sanatorium and Sucheng District People's Hospital, with geological exploration by Xuzhou Tiandi Geotechnical Engineering Technology Co., Ltd., design by Beijing Zhongyuan Engineering Design Consulting Co., Ltd., supervision by Huai 'an Huaigong Supervision Engineering Co., Ltd. and construction by Jiangsu Times Construction Engineering Co., Ltd. The project has twelve floors above ground and one underground floor, with a building height of 46.850m and a building area of 22,472.97m2, including 2,226.55m2 underground and 20,246 above ground. External wall insulation adopts 50-thick cement foam board, roof insulation adopts 125-thick cement foam board, glass curtain wall and external window adopt broken bridge insulation aluminum profile, and double-layer hollow LOW-E glass.

Second, the supervision work deployment

Our supervisor will appoint an experienced and conscientious supervision engineer to supervise this project during the construction stage. The supervision engineer has prepared a detailed supervision plan for this project. This paper focuses on the supervision methods and detailed rules of key and difficult points in the construction process. Ensure that the supervision work is carried out effectively and smoothly, and better safeguard the legitimate rights and interests of owners.

Three. The foundation of supervision work

1, engineering construction drawings, minutes of blue prints.the design, geological survey report and other design documents.

2. Engineering construction contract and entrusted supervision contract.

3, construction quality acceptance specification and mandatory provisions of engineering construction standards.

4, construction project supervision specification.

5. Existing national laws, regulations, norms and standards.

Four, the main quality supervision and control situation

1. Quality control of raw materials

Steel, cement, brick, sand, stone, etc. The materials used in this project are sampled by witnesses on the spot and sent to a qualified testing center for testing before use. All the above materials have certificates. In the later stage of construction, aluminum alloy doors and windows, PVC pipes and fittings, exterior wall coatings, glass, energy-saving materials, etc. They were all inspected at the scene when they entered the scene. After confirming that the materials meet the design requirements and construction specifications, they are allowed to enter the construction. In the process of pouring concrete and building brick masonry, the site supervisor can do a good job of witness sampling in time, and the construction unit actively cooperates with the work to ensure that the construction materials are reasonable and standardized.

2. The control of reinforced concrete engineering

The start and end of each working procedure of reinforced concrete engineering is proposed by the construction unit, and the next working procedure can be started only after the quality meets the construction and design requirements through self-inspection. In the process of formwork support, check formwork elevation, formwork size, support, formwork surface cleaning, etc. , and complete the template verification of this layer before steel binding to confirm that the template support of this layer completely conforms to the design drawings and related designs.

Modify the notice for construction to ensure the smooth transition of formwork supporting process and steel binding. Steel bar cutting table should be strictly reviewed before steel bar production, and the anchorage length, lap length and welding part diameter should be strictly controlled during steel bar production. In the process of steel binding and installation, the construction unit found no leakage of steel bars. Concrete pouring process is the key to quality control of supervision. The construction unit is required to carefully check the formwork support system to ensure the safety of the construction process, and concrete can be poured only after approval. Thanks to the active cooperation of the construction unit, the supervision work has been implemented. From the inspection after form removal, it is found that there are local pits, which are all handled by the supervisor. The inspection report of each layer of concrete pressure specimen meets the design strength requirements.

3. Quality control of architectural decoration engineering

Before entering the indoor and outdoor decoration project, the construction unit has been required to make a good sample and let the construction unit make quality and technical disclosure to the relevant subordinate teams. Under the supervision of on-site supervision, the quality of internal and external walls is good, and the flatness and verticality are good. Paste joints of wall tiles and floor tiles should be straight, free from hollowing, and meet the design requirements. Aluminum alloy window and insulating glass are constructed as required, and the exterior wall is made of matte metal fluorocarbon paint, which has passed the inspection.

Verb (abbreviation of verb) construction safety and civilized control

The construction unit has done a good job in three-level safety education, safety technical disclosure and pre-shift safety learning for each team, and designated a full-time person to be responsible. The construction unit shall make safety inspection and records of distribution boxes and various machinery every day. On-site construction personnel's general safety awareness and consciousness are not high enough, such as not wearing safety helmet, dragging cables, pulling and connecting power lines indiscriminately, etc. However, after repeated urging and correction by on-site supervisors, there has been obvious improvement. Building electricity,

The electricity used in barracks and dormitories shall be used in strict accordance with the requirements. In terms of civilized construction, sometimes the accumulated water on the site is not cleaned up in time, and the stairs are not safely closed, which has a great influence on civilized construction. After urging, this phenomenon was put an end to. In other respects, the construction team did a good job.

Progress investment control of intransitive verbs

On-site supervision requires the construction unit to provide the monthly report of labor force, materials and machinery, the monthly report of construction task completion, and the detailed plan of construction progress next month. After the report is approved, the construction unit will implement it according to the construction plan. In the process of construction, track the construction progress in time, compare the planned progress, ensure the smooth implementation of the construction progress plan, and master the whereabouts of the project construction funds. After the audit, verify the actual completion of the month's construction and the changes of the construction drawings, and report to Party A. After each audit of the project progress, the project payment shall be signed and paid according to the facts.

Seven, engineering quality acceptance evaluation

On August 20th, 20xx and February 25th, 12, the foundation and main structure of the comprehensive ward building of Suqian Rehabilitation Military Sanatorium were inspected, all of which were qualified. 20xx x month x day, my supervision unit organized various professional supervision engineers to pre-accept the project completion, and asked the construction unit to rectify or repair some existing problems. After the rectification, it was accepted. Main engineering divisions of each unit, including foundation and foundation, main structure, building decoration, building roof, building electricity, building heating, water supply and drainage, building energy saving, etc. , assessed as qualified, the project quality meets the requirements of design and construction quality acceptance specifications, the engineering entity meets the requirements of safety and use function, and the quality control data is complete and effective, so the unit project is assessed as qualified.

Annual work summary, Project Supervisor II. Work Review:

Before 20xx 10, I was engaged in civil engineering supervision in the project supervision department of xx Park of the company and served as on-site supervision. The total construction area of xx Garden Project is about 200,000 m2, and the contracting method is general construction contract.

Block 18. XxB films are all c 17 multi-storey houses *** 17. Building 92, xxc low-rise villa area. XA 1 65 low-rise villa. Xxc film low-level cargo area 18 building. During my work in the project supervision department, I was mainly responsible for the inspection of the construction site, the final acceptance of the station and sub-processes Under the guidance of the supervision engineer, I conducted a thorough inspection of all parts and links of the construction, tried my best to supervise in advance, and was good at finding problems, and stopped them immediately when they appeared, so as to avoid the occurrence of problems. If there is any problem, find out the cause of the problem, deal with it as soon as possible, and report the problems that cannot be handled and major problems to the supervision engineer in time. Always guide and measure your work with the supervision principle of "abiding by the law, honesty, justice and science". In the supervision work, I always take the attitude of being responsible for the company, the project and myself, consciously resist the influence of all kinds of bad thoughts and behaviors, and be able to correctly use my professional and technical knowledge and perform my duties.

20xx 10, due to personnel changes in the company, I came to the first phase construction project of xx Industrial Park as a documenter and site supervisor. This project consists of a1-a10 and B2 buildings. Among them, A 1 is the production debugging center, A2 is divided into two general workshops, A2-3 is the purification workshop, A2-4 is the logistics center, A3 is the power center, A4 is the chemical warehouse, A5 is the staff canteen, A6 is the shift dormitory, and A7-A 10 is the four guard rooms. Building a 1-a 10 * * * covers an area of 18244. 67 million pounds. The building area is 68,886. 5m2, divided into bid A (xx Construction Group Co., Ltd.) and bid B (Zhongjian xx Bureau Co., Ltd.). At work, I mainly cooperated with Li Jinxing to sort out and collect supervision data, and went to the construction site for inspection in my spare time, earnestly completed the tasks arranged by the company leaders and Li, and worked hard. He is on duty day and night, and often works overtime at night until the early morning of the next day. The hard work of supervision is self-evident.

Through these months of work practice, my professional level has been improved to a certain extent, and my professional knowledge has been continuously enriched. Go deep into the construction site, work hard, and implement all-round, all-weather and whole-process supervision work in the supervision construction process. Work hard according to the requirements of the director, the director's representative and the civil engineering supervision engineer. As long as the construction site is normal, there will be a supervisor on the site, demanding ideological progress, establishing the work spirit of loving and working hard, and constantly improving themselves. At the same time, there are also shortcomings in my work in recent months. My knowledge of building construction is still relatively lacking, and I need to continue to learn and improve in my future work. In terms of supervision station, some work details are not handled perfectly, and future work must be reliable. Strict work style strives to improve one's own job, meet new challenges with a brand-new working attitude, enter the new year with a brand-new working face, work hard under the leadership of the chief supervision engineer, the representative of the chief supervision engineer and the professional supervision engineer, and contribute one's meager strength to all the work of the supervision department.

People say that data management is troublesome, but I think as long as I have practical experience in sorting out data, data management is relatively easy. First of all, I classified and standardized the supervision files according to the compilation method of supervision files, separated the supervision data from the construction data, placed a personal supervision file cabinet in the annual work summary, marked the supervision and construction data in front of the cabinet, and kept the contents in the file box at any time, so that the information would be clear at a glance and the context would be very clear. At ordinary times, when other supervision engineers are busy, I also check and accept the inspection lot of reinforcement, formwork and basement waterproofing on site and work, so that the supervision work can ensure the normal operation of the construction progress.

Second, the next work plan and experience:

Next year, the workload of the first phase of xx Industrial Park will be heavier, with 24-hour continuous construction, and the main projects will be started one after another, and the workload of supervision will also increase. I will use my theoretical knowledge and accumulated practical experience to check and accept the project in strict accordance with the construction specification, supervision specification and supervision contract, so as to ensure the quality of the project, make the project supervision department successfully perform the contents agreed in the supervision contract, and make the owner more satisfied with the supervision work.

At the end of the year, the project supervision summarized that I am xxx, 26 years old, majoring in construction engineering management, with the title of assistant engineer and the qualification of second-class constructor. He joined our company on May 20th, 20XX, and was appointed by our company as the civil supervision engineer of seven projects, including Building 9 of x 17r 1 plot residential project in the southern new area of Beijing Economic and Technological Development Zone. Seven projects, including x 17r 19# Building in the Southern New Area of Beijing Economic and Technological Development Zone, are composed of three 24-storey and three 27-storey high-rise residential buildings with large underground garages around them, with a total construction area of 122240㎡, and the projects have entered the stage of completion acceptance. Looking back on the work of the past year and looking forward to the new tasks and challenges that our regulatory authorities will face next year, I feel a lot. In retrospect, the first thing to thank is the concern and trust of the company leaders and the great help and support of colleagues.

Since I entered the construction site, I have always adhered to the standard of a high-quality management talent to define myself, love my job and earnestly complete all the work entrusted by the company's leaders and Party A. In my daily work, I can strictly define myself with high standards, stand ready within the scope authorized by laws and agreements, and strictly perform my post duties. I neither mingle with the construction unit nor insist on keeping a necessary distance from the construction agency. Stand in a fair position and solve some problems on the construction site independently.

In the process of supervision, I pay attention to "quality, progress, investment" and safety to control, mainly emphasizing pre-control and prevention, and nip in the bud. Combined with the inspection and acceptance of process control, on-site control and post-event control.

Quality control: before construction, review the quality assurance system and safety technical measures of the construction unit, timely require the construction unit to rectify the non-conformity with the project plan, supervise and inspect the implementation plan of the construction unit, urge the construction enterprise to improve the quality and safety management procedures and management system, and supervise its effective implementation of 202 1 supervision. Construction personnel at all levels are required to hold relevant certificates. Check the validity of drawings, atlas, specifications and standards used by construction enterprises, and check the accuracy of measuring instruments and measuring instruments used (whether in the appraisal period). Review the materials, equipment and components entering the site. At present, the project has entered the stage of completion acceptance, and our department has formulated a weekly comprehensive quality and safety inspection system for construction units organized by the project department. The inspection mainly includes the following problems: the results of the last inspection, which problems have been rectified and which problems have not been rectified, and which problems have been found in this inspection, which are reflected in the weekly, monthly, weekly and monthly inspection records of the supervision. During the daily patrol, I notice the quality and safety hazards in time through oral notice or notice to the supervision engineer, so that the construction unit can make timely rectification. Sign the accepted sub-items and sub-projects every day, and timely summarize and file the information submitted by the construction unit to prepare for the smooth acceptance.

Time limit control: strictly supervise the construction enterprises to organize the construction according to the time limit specified in the approved schedule, urge the project department of the construction unit to prepare the schedule according to the time periods such as year, month and week, and review the guarantee measures for the implementation of the schedule submitted by them. Check the progress of the project image in time, report the progress of the project to the construction unit and analyze the reasons for the deviation! .

Investment control: carefully review the monthly, quarterly and annual engineering quantity statements of this major, so as to ensure the accuracy of the engineering quantity in the engineering quantity visa. Without acceptance or experience, those who do not meet the requirements will not be signed for approval.

At work, I cherish my reputation, adhere to honesty and self-discipline, fulfill my duties, refuse to accept illegitimate interests, put my position in order, and refuse to recognize my fellow villagers and call me brothers at work. Solve problems in work fairly and timely, regardless of time and remuneration at ordinary times, and stick to their posts on rest days and holidays.

20XX years passed quickly. Looking back on the supervision work in the past year, the deepest experience is that to do a good job in supervision, we must be strict and conscientious and have a strong sense of responsibility. No matter how complicated the project is, as long as the supervisors can perform their duties in strict accordance with the construction norms and regulations, they can fully grasp the whole project dynamics and control the whole project quality. At the same time, the professional quality of supervisors is very high, and for every working procedure and every link, it is possible to prompt in advance what may happen. In a word, my experience in one year's work is that as a supervisor, only with good conduct, concise business, good use of my own experience and authoritative test, clear purpose, rigorous style and respect for others can I get respect and recognition from others. As engineers and technicians, only by constantly improving their professional technical level and business skills, improving their communication skills and adaptability to the environment, can they better serve the construction of the project, promote the improvement of the project quality, and thus make themselves better developed. In my work, different pressures are also rare challenges and tests for me. Although there were many difficulties and twists and turns in my work in the past year, looking back, I learned a lot, learned a lot, and summed up many experiences and lessons, which laid a solid foundation for better work in the future.

The past has passed, and the lessons of achievements and failures can only represent a kind of past experience. Future development depends on continuous efforts and creation in the future.

For myself, in my future work and life, I will constantly improve my own shortcomings, sum up experience and lessons, constantly improve my professional and technical level and professional quality, constantly enrich myself, and make greater efforts for next year's work plan. At the same time, I usually pay attention to self-charging, search online for exam information in time, strive for more professional qualifications for myself, strive for an early postgraduate entrance examination, and make myself capable of going to the next level. Strive to improve their comprehensive quality from all aspects, advance towards the goal of comprehensive management of talents, and make greater contributions to the company and themselves.

XX year is coming, and there is still a long way to go in the new year. I want to meet the challenge with a new working attitude and enter the new year with a new working face. I firmly believe that with the guidance of the company leaders and the help of my colleagues, I will be able to better complete the tasks assigned to me by my superiors and make my due contribution to the development and take-off of the enterprise.

Summary of project supervision at the end of the year 4 According to the entrusted supervision contract, xx Branch of our company xx Project Management Co., Ltd. undertook the supervision task of xxx county government business room and cadre turnover room.

It is expected that the foundation will be completed by the end of July, the main body will be capped before mid-September, and the infilled wall and local plastering will be completed before mid-October/kloc-0.

Second, the supervisor's work.

According to the requirements of the supervision service contract, after the two parties signed the supervision entrustment contract, the overall objectives of project quality, progress and investment supervision were determined, and the project supervision department was established. According to the supervision contract and the Code for Supervision of Construction Projects, the list of supervision projects is decomposed, and the responsibilities of the chief supervision engineer and professional supervision engineer are defined. Make the supervision work institutionalized, standardized and standardized to ensure the smooth implementation of the supervision task.

With the strong support of the owner and the company, the supervision of this project is progressing smoothly. In the whole supervision project, we strengthened and standardized the management of the supervision itself, strictly implemented various rules and regulations, and ensured the project quality and the earnest performance of the contract.

At the same time of strict supervision, in view of the problems existing in project construction and management deficiencies. Intensified the "strict supervision" and strengthened the patrol force. More reasonable suggestions were put forward, and "prior supervision" and "active supervision" were strengthened. In the process of supervision, 100% of concealed works and key parts are in a wait-and-see state, and they are checked repeatedly at ordinary times to nip the engineering quality problems in the bud.

Third, the project supervision and management:

Examination and approval of the overall commencement report and the commencement report of sub-projects: Our supervision department will examine the contractor's labor, materials and machinery input, the rationality and feasibility of the construction scheme, the concrete measures to ensure quality and the construction of the contractor's quality inspection system in strict accordance with the requirements of ensuring the construction period and quality and meeting the contract conditions.

The handover of sub-projects is the focus of supervision's daily work and quality control of engineering construction. The supervision department shall conduct a comprehensive inspection of the previous working procedure first, and confirm that it meets the relevant requirements after treatment, before it is allowed to move to the next working procedure.

The supervision department conducted a strict inspection on the ex-factory certificate, model, specification and ex-factory date of the materials entering the site for this project. After the arrival of raw materials, the contractor shall conduct re-inspection and supervision sampling inspection in strict accordance with the specified batch, so as not to miss the inspection, and make clear the parts where the materials are used.

The problems found by the station and patrol should be notified orally at the scene in time, requiring the construction unit to rectify. If the problem is serious or the contractor fails to make rectification as required, the supervision department will issue a notice to the supervision engineer. All the quality problems found were rectified under the supervision of the regulatory authorities and ordered to be closed.

Fourth, the project schedule management

Overall construction progress plan, phased construction plan and monthly construction plan reported by the construction unit. The supervision department has comprehensively considered the requirements of the contract period and the principles conducive to the project quality. In view of the reasonable input of labor, materials and machinery required to complete the plan, to ensure the construction plan and quality assurance of the contractor's planned completion, the supervision department made a reasonable adjustment reply after detailed examination. When the construction period is tight, the construction unit is required to reverse the construction period, and the contractor is required to invest the necessary equipment, manpower, material resources and financial resources, organize scientifically and manage strictly to ensure the normal progress of the construction.

Verb (abbreviation of verb) clean government construction and safety management

The supervision department actively follows the requirements of the owner and superior departments in the aspects of clean government construction, civilized construction, safety and environmental protection. And organize relevant meetings regularly, so that every supervisor can work honestly and fairly. Monitor the implementation of safety measures and the results of rectification. Up to now, there have been no safety accidents in this project.

In short, in the construction supervision work, we have grasped the important parts and key links, put prevention first, and always strictly control to ensure quality. The project is safe and reliable, and meets the design and specification requirements. We will correct the existing problems in time with a rigorous and pragmatic working attitude, overcome the ineffective factors, intensify our work, and hand in a satisfactory project answer sheet for the owner!

According to the relevant laws, regulations and mandatory standards of engineering construction, official website, China compiled the quality supervision scheme of building energy-saving projects, which effectively promoted the implementation of building energy-saving work.

Problems in intransitive verbs

Although some achievements have been made, there are still some problems and deficiencies, and some work needs to be further consolidated and deepened. Here are some questions:

1, a small number of construction units lack awareness of laws and regulations on engineering construction, disrupting market order, conniving at blind construction of construction enterprises without going through construction permit and quality supervision procedures, and affecting engineering quality and supervision.

2. There are some problems in the supervision unit, such as lax management, incomplete system, low quality, inadequate on-site supervision personnel and failure to supervise according to regulations. After some supervision units undertake supervision tasks, there are not enough supervisors, and they do not conduct on-site supervision according to regulations, and the director rarely goes to the construction site. On-site supervisors have low professional ability and can't find quality problems in time.

3. The construction unit has problems such as subcontracting, illegal subcontracting, linking, and unauthorized construction with incomplete procedures.
