Summary of construction project supervision (I) I. Work situation
Just arrived at the construction site, in a different place, but faced with objective unfavorable factors such as large supervision tasks, wide supervision area and few supervision personnel. So I did encounter some difficulties in the actual supervision work. I didn't flinch in the face of difficulties, and I made progress despite all the difficulties. In practical work, I actively communicate with the owners and contractors to coordinate various relationships, so as to carry out supervision work as soon as possible, and take the time to familiarize myself with the construction drawings and related design instructions. In the shortest possible time,
In the actual supervision work, I require the construction unit to implement total quality management, establish and improve the quality assurance system, and make reports on commencement, construction measures, technical disclosure, positioning review, material and equipment inspection, concealed works, quality inspection, special inspection and completion data.
In the aspect of engineering quality control, we should combine active control with passive control, actively carry out supervision work, and focus on prevention. Review the contractor's qualification, focusing on the enterprise registration certificate and technical level, submitting relevant documents (copies), understanding the general situation of technical force, main building installation experience, etc. , and check the supply of sand, stone, cement, steel and the mixture ratio of concrete and mortar.
According to the characteristics of the project and the key parts that affect the quality of the project, review the construction organization design submitted by the contractor, put forward improvement suggestions in view of its shortcomings, and check the original vouchers, test reports and other quality certification documents of the purchased materials.
Control in advance to ensure that engineering quality accidents do not occur or occur less. Such as winter construction, low temperature, concrete pouring, masonry, wall plastering and other quality problems. It is not easy to guarantee. Therefore, the construction unit is required to provide a winter construction plan to prevent in advance and avoid freezing injury.
For important engineering parts and subdivisional works prone to quality problems, quality pre-inspection measures shall be formulated. For example, in the concrete pouring project of civil engineering, the leveling of beam is a key part of the project, which involves many processes such as wall masonry, formwork, steel bar binding, concrete pouring and so on. Once negligence may cause engineering quality accidents, once quality problems occur, the consequences will be serious. Therefore, in this part of the construction, strengthen monitoring, take on-site supervision measures, and strictly supervise the construction of various parts, which will affect the construction quality. Strengthen process control. During the construction supervision of Wujin Jian 'an Construction Team, it was found that there were quality problems in the building material fly ash bricks used by the team. Although the contractor has a laboratory quality inspection report, in the attitude of being responsible to the owner, the batch of bricks are sampled by parallel inspection in time, and the construction unit is allowed to use it only after all the strength indexes are determined to meet the design requirements. There are also quality problems in concrete pouring, masonry and wall plastering. In order to ensure the construction quality, I issued a supervision notice in time, requiring the construction unit to repair the defective parts to meet the quality standards required by the design and specifications.
In the supervision work, the construction unit is required to carry out the construction according to the design content, design requirements and construction acceptance specifications to ensure the construction quality. In the construction of each working procedure, the construction unit is required to strictly implement the national and local construction and installation quality inspection system, check and confirm the relevant construction quality statements submitted by the construction unit in time, and review and sign the completed project quantities declared by the contractor according to the design documents and the provisions on the calculation of quantities in the contract. Supervision record is an indispensable part of engineering supervision. I have a complete and sufficient supervision diary, which records the relevant situation of the construction site every day in detail, providing a reliable basis for solving the dispute between the owner and the contractor fairly.
During the supervision of the three construction sites, I actively coordinated the relationship between various units, making them cooperate with each other, support each other, and do a good job of cohesion to ensure the construction quality and progress. Through the above work, I completed the civil engineering supervision of the workshop office building project of Tian Li Turbocharger Equipment Co., Ltd., the workshop office building project of xx Yamazaki Motorcycle Equipment Co., Ltd. and the comprehensive workshop project of Zhongdi Electric Co., Ltd.
The three-month supervision work has yielded a lot, but there are also shortcomings. For example, I am an environmental engineering major, and I don't know much about civil engineering, and some process requirements are not very familiar. The supervision industry needs supervision engineers to have rich knowledge of multi-disciplines and multi-industries, so I need to continue to study hard in various disciplines and constantly improve my business ability and professional level.
Second, some suggestions.
1. Strictly implement the supervision procedures.
At present, the on-site supervision work is not completely carried out in accordance with the supervision procedures, such as design disclosure, joint review of drawings, first site meeting, introduction of supervision engineers and supervision contents to owners and contractors, formulation of supervision plans and supervision details, etc. , leading to the supervision engineer to the scene after no one cares, do not know the scope of supervision and how to supervise and other practical problems. In order to avoid the recurrence of such problems in the future supervision work, it is necessary to strictly implement the project construction supervision procedures so that the supervision engineer can clearly supervise.
2. Improve the organization of the project supervision department.
Project supervision institutions are fully staffed, with clear responsibilities of chief supervision engineers, professional supervision engineers and supervisors, and complete communication and transportation facilities. Due to the long route and wide area of municipal engineering supervision, only convenient transportation can ensure the inspection and on-site supervision of each construction section, so that there will be no mistakes in the supervision work and the quality of the supervision work will satisfy the owner.
3. Train supervisors to improve the quality of all employees.
Strengthen the training of supervisors, organize employees to seriously study the Supervision Code and the Regulations on Supervision of Local Engineering Construction in xx City, unify supervision standards, participate in various classes held by the Municipal Construction Committee and the Quality Supervision Station, understand and master new policies and standards, and consolidate the foundation of supervision work.
The above is a summary of my supervision work in the past three months. Because of my short working time in the company, some problems may be one-sided, and there are still many shortcomings in my work. Please ask the company leaders and colleagues to make more corrections in their future work.
Third, the internship experience
The intense three-month internship life is over, and I still have a lot of gains in these three months. It is necessary to sum up after the internship. First of all, through more than three months of internship and practice, I have learned a lot of practical knowledge. The so-called practice is the only criterion for testing truth. Through practice, I have closely observed the whole building construction process and learned a lot of applicable and specific construction knowledge, which I seldom contact and pay attention to at school, but it is also very important and basic knowledge.
While studying and practicing many specific construction methods in and out of class, I also have a more real and in-depth understanding of many specific construction details and management processes.
Construction project is the construction process and achievement of a building product by the production object of a building construction enterprise, which can be the construction of a building project, or the construction of a single project or a unit project. Its main features are: first, the construction task of building projects or single projects or unit projects; Second, the enterprise construction enterprise is the main body of management; Third, the scope of the task is determined by the project contract. Construction project management includes the following aspects:
A, the organization and management of construction projects
Second, the construction quality management
Third, the cost management of construction projects
Four, construction safety production and civilized construction management
To manage a project well, it is necessary to control the specific construction steps from all aspects. The management experience and practices mentioned above are all obtained by combining knowledge learning with construction site work in recent years. College life is tense and full of expectations. In my spare time, I always look forward to packing my bags, staying away from my relatives and friends and teachers, and going my own way. However, when we can finally leave the nest built by our elders and walk on the big stage of social work like a fledgling eagle, we find that the road of life is so bumpy that everyone's success has experienced some storms.
During the short three-month internship, I learned a lot. I continued to work hard and study in the society, adjusted my mentality, changed from a passive state when I first started social work to an active state when I started to adapt to society, and continued to devote myself to intense work with a relaxed mood and abundant energy.
This internship made me deeply realize that reading is a way to increase my knowledge and broaden my horizons, but it is also an excellent choice to improve my comprehensive quality through more practice, being in the middle of practical things, touching the pulse of society and setting a position for myself. The school arranged an internship to learn practical knowledge in the big school of society. This is also my first real contact and feeling with society.
I'm very happy to be in xx Cheng Zhen Supervision Company, and I'm honored to be exposed to these masters who have taken me with them and given me knowledge and help in my work, so that I can fully combine the theory and practice I have learned in practice and make clear my future development direction. Although I encountered some obstacles such as language at the beginning of my internship, I made myself aware of my shortcomings, studied hard, worked hard and actively faced every new opportunity.

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 intensity of "strict supervision" and strengthened the power of sideline patrol; 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!

Overview of construction project supervision (III) I. Overview of the project
Xx Qili Resettlement Community Phase III has a total investment of 340 million yuan, with a total land area of138,608 hectares and a total construction area of 207,502 square meters. Among them, the multi-storey building area is 1 17096 square meters, with 50 buildings; The high-rise building covers an area of 76,998 square meters, with *** 1 1 building; The commercial building area is 8800 square meters; Kindergarten building area 1 168 square meters; Construction area of community center1028m2; The underground garage has a construction area of 9000 square meters and 4 underground garages. The plot ratio 1.49, the green space rate is 32.5%, and the total number of households is 2040.
Second, the quality control
1, strictly control the quality of materials.
For the materials entering the site, the material certificate is required to be complete, and the materials can be put into use only after the supervisors witness the sampling materials and pass the inspection. Resolutely put an end to unqualified materials entering the site. For example, before the structure construction, timely urge the construction unit to send inspection for materials such as steel bars, cement, sand and gravel, and send inspection for welded joints of steel bars, and emphasize that special types of work such as welding should hold relevant certificates. For the material inspection results sampled by the construction unit without the witness of the supervisor, we declare them invalid and require re-sampling inspection.
2, from beginning to end, emphasize the quality consciousness, strict requirements, not resolutely rectification.
In the month after the start of the main project, we have made many rectifications to the construction unit. Before pouring concrete, the construction unit is required to take out the concrete pouring scheme, organizational measures, personnel arrangement and general layout of the construction site for technical disclosure to ensure that 80% of the concrete is poured in place at one time. In order to avoid the phenomenon that the material can't be supplied in time in the casting process, continuous casting can't be realized. When can the second layer of concrete be poured after the rectification is in place? After nearly a week's rectification, the construction unit held several management meetings and team meetings respectively, and strengthened the mixing intensity of on-site concrete. So as to ensure the quality and progress of the project.
In painting, decoration and installation projects, we also have strict requirements, and all processes are inspected and controlled with Excellence as the standard. Do not conform to the design and construction specifications, we insist on written forms such as supervision notice and engineering quality rectification notice to require the construction unit to handle or rework according to the design and specification requirements, and we also encourage and support them in time. Subsequently, with the cooperation of the supervisor, the construction unit also showed high enthusiasm; In terms of quality, we also take the initiative to be strict with ourselves.
3, emphasize the self-inspection, at the same time adhere to the tracking inspection and sampling work.
We require the construction unit to complete the "three self-inspections" of each working procedure, and then apply for inspection. If the previous procedure fails to pass the inspection, the construction unit shall not carry out the construction of the next procedure.
At the beginning of the project, although the construction unit still applied for acceptance, there were piles of problems, including some common sense problems; Sometimes inviting supervisors to accept the unfinished work of the working procedure clearly shows that they have omitted the self-inspection link. In this case, we refuse to accept it.
Of course, we don't forget to follow up while waiting for the inspection. Finding the problems in the construction process in time and pointing them out in time can avoid the large-scale rework of the construction unit and speed up the construction progress. For example, in the process of steel binding, it is often found that the construction unit missed the cantilever duck reinforcement and the column stirrup range error, and all of them were corrected in time.
Sampling inspection is an important part of our project quality control. It is said to be a random inspection. In fact, we conduct a comprehensive inspection of more subprojects or processes. The point is that we have conducted several rechecks. For example, when concrete is cast, we always check the slump and mixture ratio of concrete to ensure the quality of concrete. Under normal circumstances, after the formwork removal of beams and columns, we will conduct a comprehensive inspection of the steel bar binding and formwork support sub-projects and conduct re-inspection to prevent the deviation caused by unexpected factors. Through follow-up inspection and sampling inspection, we found many problems in construction in time, put forward opinions to the construction unit in time, and tried to solve the problems, which also established the prestige of our supervisors and made the construction unit feel that we were not only supervising them, but also assisting them.
Third, schedule control.
Progress and time limit for a project are also important parts of our control. After the construction unit comes up with the overall progress plan, we require the construction to be equipped with the overall network diagram, and take out the monthly plan and weekly plan on time. The weekly plan shall be checked and implemented at the weekly meeting, and the monthly plan shall be implemented when reviewing the monthly progress payment of the construction unit. When the weekly plan and monthly plan are not completed on schedule, please ask the construction unit to analyze the reasons first, and then come up with measures to catch up with the lagging progress. When the project reaches a certain stage, the construction unit is required to clean up the workload and reverse the scheme. Supervisors often communicate with the person in charge of the construction unit to understand the reasons for the difficulty in completing the progress, and make suggestions and find ways for the construction unit in time. For example, in the structural construction stage, due to the large amount of steel pipes and templates, it is difficult to turn around. We report to the leaders of the construction unit in time and ask them for their support to ensure the progress of the project.
Fourth, investment control.
In the process of project implementation, the supervision department strictly examines the engineering measurement submitted by the contractor and signs and seals it according to the actual completed engineering quantity. Treat the design changes proposed by all parties with caution, carefully examine them, and effectively control the increase in investment.
Verb (abbreviation for verb) coordinates work.
In the early stage of the project, we coordinated the work contact between various units, mainly civil work. Later, the installation work was carried out in an all-round way, with many construction teams and coordination work. On the one hand, we emphasize that all construction units should cooperate and communicate with each other; On the other hand, grasp the progress of each unit in time, make overall consideration and make overall adjustment.
Approval and implementation of various schemes of intransitive verbs
Since the project started, 22 * * * plans have been approved. Our department shall timely examine and approve various plans submitted by the construction unit, and the construction site shall be carried out in strict accordance with the construction plan. Notify the contractor in the form of our quality defect supervision notice, and send 3 1 quality supervision notice; When the superior supervision department came to Qili Phase III inspection, I received 25 quality and safety rectification notices accompanied by the supervision department, and the problems raised were rectified in strict accordance with the requirements of the superior leaders. The head office came to our department three times and raised relevant questions. Our department requires the construction unit to report to the head office for review after rectification is in place.
Seven, safe and civilized production
Safety management is also the focus of our work. In management, adhere to the policy of safety first, prevention first, prevention and treatment by groups and people-oriented, and increase on-site safety management. In particular, major hazard sources have been controlled and on-site inspections have been intensified. When potential safety hazards are found, timely issue a rectification notice of 14. Three notices of shutdown and rectification were issued for major hidden dangers, and on-site guidance was provided for rectification and tracking services. We actively cooperated with the inspection of higher authorities and the head office, actively urged the construction unit to rectify the problems found and responded in time, adhered to the system of on-site regular meetings and special meetings, severely criticized those who failed to rectify, and ordered them to stop rectification and stop acceptance. Through the above management methods, there was no safety accident in Qili Phase III, which was well received by the higher authorities. In the future work, we will, as always, strengthen safety management, do our job well and hand over the project to the owner with good quality and quantity.
Eight, important process and disciplines, division of engineering quality certification:
The important working procedures, sub-items and sub-projects of this project, from materials to structural entities, have been tested and certified by qualified testing and testing units. The current situation is as follows:
23 copies of the acceptance records of the foundation trench and foundation, 1 1 copy of the quality acceptance records of the sub-projects, and 408 copies of the compressive strength test report of the shuttering concrete of the main structure; Standard concrete compressive strength test report 6 16 copies; 596 test reports on compressive strength of concrete under the same conditions; 440 raw materials; 44 blocks for backfilling, drawing and autoclaving; 748 concealed engineering acceptance record.
Nine. Concluding remarks
