Summary of the first quarter work of the Engineering Department

Last quarter has passed. Is the project completed? How's the progress? It’s time to write a work summary. The following is the first quarter work summary of the Engineering Department. Welcome to read it!

Time flies, and the year 20xx flies by in a busy and intense manner. Under the leadership of leaders at all levels, the Engineering Department has joined hands with other departments to participate in the construction of the Capital Airport for 1xxxx months. Looking back on 20xx, we have experienced various stages of breaking out of ±0, completing the pouring of the main concrete structure, completing the hoisting of the steel structure, successfully closing the steel grid, completing the secondary structure and rough decoration ahead of schedule, and fully launching the construction of glass curtain walls and metal roofs. stage. The engineering department works diligently and hard-working at every stage of the work, actively and proactively completes the tasks assigned by leaders at all levels, and on the basis of doing its job well, continues to study and study, and strives to improve its professional level; at the same time, Ideologically, I must strictly demand myself, constantly strengthen party spirit, and participate in learning activities on time to maintain the advanced nature of Communist Party members; I must be hard-working, simple, truth-seeking and pragmatic in my style, and work hard for the construction of the Capital Airport T3B project. We summarize the work in 20xx from the following six aspects:

1. Construction progress management and production plan application:

The engineering department is the department responsible for the production progress, and the project progress Speed ??directly affects the nerves of every employee in the Engineering Department, and they make objective judgments on the work of the Engineering Department every second. To this end, the Engineering Department has made every effort to do every job for the rapid advancement of the T3B project construction. The engineering department's management functions of construction progress are mainly reflected in the preparation, adjustment, execution, correction and guarantee measures of the production plan. The construction process of T3B project is a very complex production activity. Not only does it include organizing thousands of professional construction workers of various types and a large number of various types of construction machinery and equipment to be put into project construction in an orderly manner, but it also includes organizing a wide variety of buildings weighing tens or even millions of tons. Production, transportation, storage and supply of materials, products and components, organizing the supply, repair and maintenance of construction machinery and equipment, and arranging various temporary buildings required for production and life at the construction site. The organization and coordination of these tasks are of great significance to carry out project construction quickly, efficiently and cost-effectively.

The capital airport expansion project has a fixed construction period of 1,610 days, and the owner requested a construction period of 1,210 days. When bidding, the group company considered increasing competitiveness and after repeated discussions and negotiations, the total construction period was set at 1,085 days. It can be seen that the construction period pressure of this project is very huge. To this end, on the premise of ensuring the overall construction period target and taking into account economic costs, we formulated the construction organization principle of "large parallel, small flow", that is, the project is divided into xxxx construction area and 9xxxx flow section, and each construction area is constructed in parallel. In order to achieve the shortest construction period, each construction area is divided into several small flow sections, and flow construction is carried out in each flow section, in order to allocate labor input and turnover materials to the most reasonable state. In order to ensure the completion of the project goals, combined with the characteristics of this project, such as its large size, tight construction period, complicated procedures, and many collaborative units, we established a three-level plan management system in conjunction with each branch, forming a complete report format and information transmission channel. In order to determine the key tasks, the headquarters first used the network diagram method to prepare an overall project construction progress control plan, and divided the project into "the floor concrete construction stage, the steel grid construction stage (structure capping), and the exterior decoration construction stage (structure enclosure). ), indoor fine decoration and equipment pipeline installation stage, equipment linkage debugging and trial operation stage" five phase milestones, thereby determining the key work. Then, according to the on-site conditions, the project was divided into five major zones: ABC, D, E, F and G, and five divisions formed by five companies respectively carried out the construction. Based on the overall control plan issued by the headquarters, each branch uses the horizontal chart method to further refine the plan into each construction process, and reports it to the headquarters for approval before organizing the implementation. Finally, each branch distributes the bar graph plan to each operation team, and the operation team develops a flow construction operation plan.

A complete production plan is not just a network diagram or a horizontal chart, it should also include the basis for planning preparation, a description of logical relationships, the image parts and workload completed last month, and the planned parts and tasks next month. Workload, arrival plan of personnel, materials, and equipment, plan implementation conditions, plan guarantee measures, urgent problems, comparative analysis of plan completion status, if there are delays, measures to rush work, and project progress photos, etc. In order to improve work efficiency, all production plans are compiled using Project software. The software is unified, the version is unified, the format is unified, the requirements are consistent, and it is easy to modify, thus greatly improving work efficiency. We implement a three-level plan management system, which not only prepares the overall progress plan, but also prepares annual, quarterly and monthly plans, as well as prepares bi-weekly rolling plans every week, using the weekly plan to maintain the monthly plan, and using the monthly plan to maintain the annual plan. Ensure that the total construction period target is achieved as scheduled.

The critical line method plays an important role in construction production. The earliest applied network planning techniques are the critical circuit method (CPM) and the plan review method (PERT). During the deep foundation construction in the ABC construction area, after careful study, we decided to erect the MC480 walking tower crane on the roof of the underground floor. On the one hand, it received technical support from the construction plan, and on the other hand, it was also the key to the overall progress plan. Determined by the line. Because the shallow foundation concrete structure cannot be constructed until the steel pipe columns are hoisted and the box-shaped steel beams connected to the concrete structure are welded and fixed. It is not difficult to see from the detailed network plan that if the steel pipe columns are not installed, the box-shaped steel beams cannot be welded. If the box-shaped steel beams are not installed, the construction of the shallow foundation concrete structure cannot continue. Therefore, whether the steel pipe columns located on the key lines can complete the hoisting work on time directly restricts the pouring time of the overall concrete structure. Therefore, when we carry out the overall construction deployment, we decided to first ensure the processes on the key lines and move the deep foundation to the ground floor. Minor work such as the APM track beams and the retail bridge structure on the roof are scheduled to be constructed after the steel structure is hoisted, thus ensuring the construction progress of the overall project. By scientifically preparing the key lines determined by the network plan, it is easier for managers to concentrate on the main contradictions, ensure the construction period, avoid blind construction, and at the same time better allocate manpower and material resources to achieve the purpose of reducing costs.

What the production plan provides is the manager’s construction deployment and decision-making ideas. How to ensure that the plan and overall deployment are carried out on schedule, improve the seriousness of the plan, reduce the risk of network plan breaking, and strengthen the dynamics of the production plan. Management, increased inspection and monitoring are very necessary. The content of monitoring is comprehensive, from macroscopic construction deployment to microscopic process interleaving, every link cannot be missed. We mainly control from the following four aspects: 1) Using key lines as clues and network plan starting and ending milestones as control points, we determine key control objects at different construction stages and specify construction details to ensure the realization of control nodes. 2) Based on the overall progress, clarify the goals of each unit, implement subcontracting responsibilities through contract responsibility letters, and achieve the respective branch goals separately to ensure the realization of the overall goal. 3) Make a comprehensive balance between the tasks of different majors and different types of work, and emphasize the connection and cooperation between them, determine the date of mutual handover, strengthen the seriousness of the construction period, and ensure that the project progress does not cause delays in this process. By controlling the quality and time of completion of each process, we can ensure the progress of each branch project. 4) According to the time requirements of the overall progress plan, the overall construction progress plan is broken down into quarterly, monthly, ten-year, and weekly progress plans to increase the intensity and depth of monitoring.

The comparative analysis and correction control of production plans is a step-by-step dynamic control process. The conditions and situations at the construction site are ever-changing. We must promptly grasp all kinds of information related to the construction progress, and constantly compare the actual progress with the planned progress. Once the progress is found to be delayed, we must analyze the reasons and systematically analyze the impact on subsequent work. , and on this basis, adjustment measures are specified to ensure that the project is ultimately achieved as scheduled. The comparison of construction plans is mainly to compare the actual completion status during the planning period with the planned indicators to find out the differences. The main content of the comparison of this project plan is: the actual completed and cumulative completed projects during the planning period, the workload as a percentage of the planned indicators, the actual number of construction personnel, mechanical equipment and production efficiency during the planning period, as well as the changes that occurred during the planning period Special matters and reasons that have an important impact on the construction progress.

The construction progress control plan of this project is prepared using network technology and the most advanced domestic special project construction network planning program. Therefore, it is the most practical and fastest way to compare plans by drawing forward lines on the network plan diagram. method.

2. Construction production coordination and project subcontracting management:

While paying close attention to production progress management, the engineering department actively carries out coordination services for each division and subcontracting, Use high fighting passion and full work attitude to promote the smooth development of various tasks, and exchange efficient and high-quality services for the understanding and support of each branch and subcontractor, so as to better conduct dynamic management of production progress. It can be said that from the underground structure construction at the beginning of the year to the successful completion of the second battle, and even the full realization of various production targets at the end of the year, the engineering department's footprints are spread throughout every stage, every link, and every part.

During the structural construction, the installation of steel structures such as stiff beams, stiff columns and steel pipe columns is alternately interspersed with the construction of concrete structures. The mutual coordination between steel structure installation and civil construction naturally falls on the project On the body. The T3B structural project is a steel frame reinforced concrete hybrid structure. The steel frame is composed of stiff beams and stiff columns. After the stiff beams and stiff columns are installed, the beam and column concrete can be poured. It can be seen that the structural construction is affected by steel. The impact of structural installation is very large. The installation of steel structures is restricted by two major conditions. One is the processing and transportation of steel components; the other is on-site installation conditions, including lifting equipment and on-site conditions. For the processing of steel components, we go to the processing plant to track the component processing status, and adjust the processing plan with the manufacturer based on the on-site civil construction progress. For manufacturers whose processing progress cannot meet the on-site installation, we adopt contract division, outsourcing processing, and Track the processing status of outsourced processing plants, and urge the fifth branch to speed up the installation of incoming components to provide a working surface for civil construction. The installation part of the five-section steel pipe column is hoisted by the earth method. Some steel pipe columns are installed by the earth method and the earth method. The tower crane is used for a long time and frequently. The construction of civil structures is also inseparable from the use of the tower crane. Siphon The welding of rainwater pipes also affects the installation of steel pipe columns, and the electromechanical and electrical pipes embedded in the structural surface affect the on-site slippage of steel pipe columns. These problems need to be coordinated and solved. Failure to solve them will directly affect the construction period of the structure. The peak installation period of steel structures is in the three months of May, June and July, which are the hottest seasons. In order to facilitate the close connection between various processes, everyone sacrificed their lunch break and held a steel structure coordination meeting in the fifth department at 1 noon every day. After the meeting, we went to each area with questions to inspect and implement them, and ultimately ensured that the installation of the concrete structure and steel structure was completed on schedule.

The main concrete structure was completed on time and with high quality. We did not get the slightest chance to breathe. Then we started the construction of the steel grid and the backfilling construction around the structure. In order to create better construction operating conditions for the steel grid subcontracting unit, reduce the workload of steel grid side truss support scaffolding, reduce costs, and shorten the construction period. The engineering management department decided to backfill first and then erect scaffolding. The engineering department is responsible for the construction arrangement and coordination of the backfilling within 4xxxx around the structure and the backfilling outside 4xxxx. At this time, the civil construction materials have not left the site. There are formwork, scaffolding pipes and other materials everywhere, and the steel grid is in urgent need of assembly space. The grid materials have come into the site, and the scaffolding tubes and wooden boards for the grid construction have come in, which is very important for backfilling. This has caused a great impact, and at the same time, the on-site cables need to be dug out and moved, otherwise it will cause great waste. Many tasks are intertwined and cannot be delayed. Coordination of work is very important and very difficult. The engineering department is divided between the civil engineering branch, the mechanical and electrical branch, the municipal water affairs department and the air conditioning department. The construction of the pipe gallery in the first branch has not yet been completed, the waterproofing in the second branch is in urgent need of construction, the waterproof protective layer of the pipe gallery in the third branch has not been done yet, the scaffolding pipes in the fourth branch need to be cleaned, the fine side truss materials need to be moved, etc. , things are complicated, but every link cannot be delayed. On-site construction works 24 hours a day, with shovels, bulldozers, excavators, grading transport vehicles, and material return vehicles scattered around the structure. The backfilling of empty spaces is carried out at the same time as the backfilling of our unit, which makes the coordination work more arduous. In order to ensure the smooth progress of backfilling, the engineering department and managers from each branch worked hard at the site day and night. After more than xxx months of close cooperation, the backfilling work was successfully completed without affecting other processes. The leveling of the surrounding site created favorable conditions for future construction.

While the platform is being backfilled, the steel grid construction period assigned by the owner is also imminent.

The Engineering Department is deeply aware of the arduousness and urgency of this project, and we must not let the first subcontracted project we are responsible for delay the overall construction schedule. Therefore, the engineering department immediately adjusted its mentality after completing the main structure and entered the role in the shortest possible time. It worked overtime with Zhejiang Precision Workers participating in the construction day and night, monitored the steel grid construction site day and night, and promptly urged the fourth branch to step up After 10 days and 10 nights of hard work to build the load-bearing scaffolding for the side trusses, the first 17-ton steel truss was hoisted as scheduled on July 11, which ensured that the opening ceremony of the steel grid was held smoothly, and was well received by the owner, maintaining the Group's honor. Then the comprehensive construction of the steel grid began, but there were many problems that restricted the normal construction of the steel grid. A series of issues such as the use of splicing sites, the transportation roads for hoisting side trusses, and the access of Zhejiang Jinggong's own materials need to be solved immediately. Under the direct care and guidance of leaders at all levels of the Engineering Management Department, the Engineering Department and the person in charge of Seiko Production will arrange and implement weekly production plans and progress positions. Regarding on-site coordination issues, as long as a phone call is made, we will rush to the scene of the problem immediately. If there are any difficulties, everyone will work together to solve them. We will carefully implement the layout according to the favorable factors. When the assembly site is not available, we will immediately summon the production managers of each branch to move other materials on site according to the project needs to ensure The project went smoothly. Once the time required for hoisting the 150T crawler crane is determined, all difficulties will be eliminated to make way for the transportation road to ensure that the crawler crane can pass smoothly within the required time. The large area and number of load-bearing scaffolding bodies required to cover the entire T3B project during grid construction are unprecedented. However, even in the construction of such a large-scale structure, we were not intimidated by the difficulties. We still worked with the production leaders of each branch to follow the grid construction plan section by section and track the scaffolding erection progress, insisting on progress, safety and erection. On the premise of qualified quality, it was successfully delivered to Zhejiang Jinggong Grid Company for use. The CEO of Zhejiang Jinggong Group was very grateful to us for our cooperative spirit and attitude. Under such construction guarantee, all the participants of Zhejiang Jinggong successfully completed all the steel grid construction tasks on October 30 under the scientific construction day and night, which impressed all the fraternal units participating in the T3 project and was an honor for the Construction Engineering Group A new chapter has been added.

As soon as the grid construction was completed, another subcontractor, Shenzhen Sanxin Curtain Wall Construction, couldn’t wait to start construction preparations. The grid has not yet exited, and the materials for the curtain wall have begun to enter. Providing material sites for the curtain wall and steel truss assembly sites became the top priority. But at this time, the grid scaffolding was being dismantled, and a large number of scaffolding tubes and wooden boards were piled up on the side of the structure. The secondary structure was under construction, and materials were piled everywhere, making it impossible for the curtain wall crane to get close to the side of the structure and unable to hoist the steel trusses. The work of coordinating the work surface was once again placed in front of the Engineering Department, starting from the two wings, coordinating units one by one, then the south corridor, and finally the core area. Each working surface was cleaned in coordination with the civil engineering branch. It was quite difficult to clean such a large number of scaffolding pipes and wooden boards in a short period of time. Although there were many difficulties, with the coordination of the engineering department and the strong cooperation of each branch, The look of the scene is changing day by day. After more than a month, we have basically completed the dismantling of the scaffolding that took more than three months to erect, and completed the cleaning and exit of the materials. At the same time, under our overall deployment, each civil engineering branch quickly transferred to the construction of the secondary structure after the main structure was completed. Due to the reasonable arrangement of our department, when the climate turned cold, the secondary structure on the first floor was basically handed over to the curtain wall company, providing a working surface for the comprehensive installation of systems 2 and 3. So far, nearly 9xxxx keels have been completed, and the installation of aluminum plates, glass, and louvers has begun. However, T3A has not yet started the construction of this part of the project.

3. Labor management work:

According to the requirements of the group leaders and in conjunction with the spirit of relevant documents of the Beijing Municipal Construction Committee, the Engineering Department organized each branch to conscientiously carry out various labor management tasks. Strictly require each branch to strengthen the management of the contract system with each external construction team, and strengthen the implementation inspection of contract performance. We should conscientiously implement the payment of wages to migrant workers and strictly implement real-name management to ensure that wages are paid to every migrant worker. Especially in the work of ensuring payment and ensuring stability before the Spring Festival, the Engineering Department has assisted the project manager and secretary in convening multiple seminars on labor settlement and payment since the beginning of November XX, to conduct detailed investigations and have a detailed grasp of the labor costs of the entire project. Settlement and redemption status as well as the dynamics of migrant workers.

At the same time, we actively communicated with the group and secondary companies, and obtained the understanding and support of the group and secondary companies. We paid the unstable construction teams in advance and left the site first to eliminate hidden dangers. In addition, we get in touch with the Beijing offices of each construction team and maintain regular communication. Through the collaborative relationship between enterprises, we can alleviate the negative emotions of the construction team and negotiate to resolve labor disputes. In order to ensure payment and stability, a labor management leading group has been established and an emergency plan for labor disputes has been formulated. When a problem occurs, the leading group will be on the scene as soon as possible to actively solve the problem and prevent the situation from escalating. In the work after the Spring Festival of 20xx, on the basis of summarizing the work experience in 20xx, we will further implement and improve the long-term mechanism for the payment of wages to migrant workers. Starting from the beginning of the year, we will start from the standardization of market behavior and labor employment, and pay close attention to the long-term mechanism. implementation.

4. On-site document management:

Although the Security Department is the department responsible for on-site document management, the Engineering Department still goes all out to cooperate with the Security Department to manage on-site documents Work. The Engineering Department is specifically responsible for several control elements such as environmental protection management, on-site management, and large machinery management.

Environmental protection management work mainly includes:

1. Prevention and control of dust. The main road at the construction site (Huanchang Road) is hardened, and the mounds around the site are covered with green netting. All cement is required to be placed in a closed cement warehouse, and sand and gravel materials are piled up and covered. Watering is carried out every day (the water is used on-site after precipitation) to ensure that the road surface is dust-free and muddy. The on-site steel bar processing site and formwork processing site are all hardened, and responsibility areas are divided and cleaned regularly. If the hardened road surface is damaged, the remaining concrete will be poured into the structure and repaired in time. In office areas and living areas, greening and beautification should be carried out where possible.

2. Dispose of garbage, domestic garbage and construction garbage are stored separately. Domestic garbage should be collected in covered trash cans and removed regularly. Construction waste is stored in a closed garbage station with a sorting tank next to the garbage station. The garbage station is made of light steel structure and has a sliding door, which can be moved and recycled. Enclosed transport vehicles are used for the transportation of earthwork, slag and construction waste.

3. Prevent and control water pollution. Sedimentation tanks are set up at the cleaning areas of concrete delivery pumps and transportation vehicles in each branch. After secondary sedimentation, they are used for road watering and dust reduction. Store oil on site and prevent leakage in the warehouse. The canteen at the construction site is equipped with a grease trap, and a dedicated person is responsible for regularly removing oil.

4. In-house management uses multimedia tools to vividly reflect our environmental protection management work and provide vivid management teaching materials for future environmental protection work.

The Engineering Department does not dare to relax in the management of large machinery. It organizes joint inspections of property rights units above xxxx every month, focusing on the safe use and daily maintenance of the machinery in the production process, in order to Ensure the reasonable use of large machinery under safe production and ensure the normal progress of production. After one year of use, the large machinery has been fully utilized in the T3B project, no major accidents occurred, and the mission of the large machinery in the T3B project has been successfully completed.

5. Internal management work:

1. Project daily report: Based on the actual completed parts and physical quantities of the projects of each subcontracting unit and each branch, it is compiled and summarized in the form of text descriptions and statistical tables every day, and then the on-site construction progress and project information are promptly reported to the owner, supervisor and in the hands of relevant departments and leaders.

2. Weekly project report: Together with the plan, combined with the weekly project report of each branch and each subcontracting unit, as well as the actual completion status of the site and the physical quantity of the completed project, it is organized and summarized in the form of text narratives and statistical tables, and through three different reports Provide timely feedback on the progress of the project to the owner, on-site supervision and other relevant departments.

3. Monthly project report: Together with the plan every month, it is organized and summarized in the form of text descriptions, project photos and statistical tables based on the actual completed parts of the site and the physical quantity of the completed project, the monthly major achievements of the project management department, etc., through three types of Different report forms provide timely feedback on project progress to relevant departments such as owners and on-site supervision.

4. Measurement declaration: This work is quite troublesome and complicated; every month, the actual project measurement orders completed monthly are sorted out and summarized in six copies according to the actual project measurement orders checked by each branch and the airport expansion headquarters’ budget department and on-site supervision. Send it to the owner and supervisor.

5. Daily work contact sheets: Submit problems existing at the construction site to the owner in the form of work contact sheets and distribute them to relevant branches. This year, the engineering department issued 56 supervision work contact sheets and issued work contact sheets to each branch. ***109 copies.

6. Political and ideological learning and exchange:

The Engineering Department actively participated in the "Activity to Maintain the Advanced Nature of Communist Party Members" organized by the Party Committee of the Engineering Management Department. It has gone through various stages such as mobilization, personal analysis and evaluation, rectification and improvement, etc. Through this educational activity to maintain the advanced nature of Communist Party members, we have learned the outstanding aspects of other party members, used the advanced nature of party members to check ourselves, and found out our shortcomings in our work. Through study, I have become more deeply aware that maintaining the advanced nature of Communist Party members is a major event for the whole party and a major event for every party member. This activity has once again sublimated my outlook on life and values. As long as we seriously experience, compare and improve in our studies, our ideological realm will be greatly improved. In the future, we must effectively improve our overall quality, establish a conscious awareness of learning, proceed step by step, review the past and learn the new, persevere, persevere, and study in a down-to-earth manner, so that we can learn real skills and integrate the learned knowledge into our specific work. .
