Summary of the work of architectural decoration engineer As time goes by, the 20XX New Year bell is about to ring. On this occasion, under the correct guidance of Jinda Real Estate Co., Ltd. and the correct leadership of the real estate development company, the total construction area of the first phase development of the community is 250,000 square meters. This department is responsible for the residential building of *** 10 in Bid A of Garden Community, in which: 4 small high-rise buildings are 7 12 floors, (10, 14, 15),1/kloc. Shop 1 and 2, with an area of 743.2㎡, and engineering headquarters 1428㎡. With the concerted efforts of all the staff in Qi Xin and the efforts of the cadres and workers of the construction unit, the project department has completed the acceptance of the main structure of the small high-rise building and entered the decoration stage. The main structure of the high-rise building 1 1 and 16 floors has been capped, with 26 floors for the three-storey structure, 22 floors for the four-storey structure and 65438+ for the eight-storey structure. 12 structural building completed 18 floor. On the basis of reviewing the past, summing up experience, finding out shortcomings, enriching ourselves and making the enterprise have the stamina for rapid development, the past work is summarized as follows:
First, set goals, observe rules and discipline, and do a good job in organizational construction.
1. After the establishment of the project department, according to the characteristics and scale of the project, the company decided that General Manager Zhu would be the project commander of the project department and take charge of the overall work of the project department. Under the direct leadership of the project manager, start with the organizational structure and do a good job in organizational construction. The organizational structure of the project department adopts linear organizational structure, that is, according to the engineering characteristics and plane distribution, three regions are divided and three project departments are established to be responsible for the project construction management within the jurisdiction of this region.
2. Under the leadership of Project Manager Jiang, Project I is responsible for setting the work objectives, among which: the safety objective is: zero death. The progress target is: the small high-rise building will be completed on April 3 1 day, and the high-rise building will be completed and put into use on October 301day. The quality goal is to complete all the construction contents according to the standard requirements of the municipal high-quality project.
3. After the goal is determined, in order to achieve the above-mentioned work goal, we have formulated various feasible rules and regulations according to the executive headquarters, such as: post responsibilities, management system of regular engineering meetings, design disclosure and joint review system, construction organization design and construction scheme review system, engineering quality and acceptance management system, engineering change management system, document management system, safety and so on. Everything we do has rules to follow, evidence to check, supervision and governance, and our actions are based on constraints and governance, which reduces randomness and increases sense of responsibility.
Second, do a good job of pre-control
1, the construction period is controlled in advance:
After the time limit for a project is determined, the project department requires the construction unit of Changzhou No.1 Construction Company to make a time limit plan, arrange the time limit for a project reasonably, and report it to the supervision department and the project headquarters for review. Construction can only be started after approval. On this issue, the establishment of the project by the construction unit, the review by the supervision department and the project team department are not very serious, and they think it is unnecessary. After that, the headquarters, the project department and the supervision meeting held several meetings to explain that the construction progress plan is very important, which is of great significance to the control of the construction period and makes everyone more familiar with it. Although the on-site construction scheme is not satisfactory, our department is among the best in the three blocks and has played a role in supervision.
2, quality control in advance:
2. 1 When the construction unit enters the site, the project department strictly controls the qualifications of the personnel entering the site, and requires the management personnel of the construction unit to prepare the duty list and attach the contact information. In the process of supervision, the person in charge of the building number keeps in touch and implements the rectification measures, which has achieved certain results in promoting the progress, quality, safety and civilized construction of the site project.
2.2 After the quality target is determined, the project department requires the construction unit to carefully write the construction organization design and construction scheme before the project starts. At the same time, the key points of quality control should be trained and studied by the person in charge of the building number to achieve the purpose of supervision and application.
2.3 Before the project construction, all professional engineers are required to be familiar with the construction drawings carefully, so as to correctly supervise and guide the construction. At the same time, on this basis, organize design units, supervision units and construction units to carry out the blue prints.the design in blocks, and carefully record and sort out the blue prints.the design records according to the requirements of the blue prints.the design system as part of the design documents, and carry out the construction according to the recorded contents.
2.4 For common quality defects in construction, the construction unit shall prepare the construction scheme, and the project department shall cooperate with the planning department to carefully examine and sign it, write down the key points of construction technology and details of nodes, and unify the practice, and distribute them to the supervision unit and the construction unit, such as wall masonry, external wall tiles, internal wall insulation, roof waterproofing, door and window installation, water and electricity installation, etc. , and achieved good results.
Third, control in the process.
1, foundation engineering:
1.65438+
1.2 After the construction started, we first tested the piles according to the geological report provided by the geological prospecting units. Through pile test, the pile length and the final pressure value of the pile are determined. In the process of pile pressing, we work together with the supervision unit and the construction unit to overcome various unfavorable factors such as complex geological conditions and obstacles in underground construction, and ensure the authenticity and reliability of pile pressing records. The Project Department and the Group Supervision Department take turns to supervise and inspect to ensure the reliability of piling records.
1.3 in the pile foundation construction, according to the requirements of the code, we have done single pile bearing capacity test and small strain test for all five high-rise buildings 3, 4, 8, 1 1 2. The test results all meet the requirements of design and relevant specifications. Conclusion: The construction of high-strength static pressure pipe pile foundation is successful.
1.4 There are five buildings in this bid section, namely independent foundation and raft foundation. During construction, the person in charge of the building number should carefully check the geometric dimensions, rebar spacing and requirements.
Steel stirrups support, and make records of actual points, strictly control pouring concrete and water cement ratio, so as to ensure the quality of foundation engineering.
2. Main projects
2. 1 After the construction of high-strength static pressure pipe pile foundation is completed, it will enter the construction stage of foundation capping beam, ground beam and main short-leg shear wall. In order to ensure the correct transmission of the upper load, the office of the chief engineer of the project department requires all supervision departments and the project team to strengthen the patrol inspection and on-site supervision of the process of planting steel bars and connecting piles of static pressure pipe piles to ensure that the construction of the above parts meets the requirements of design and relevant specifications. Do not meet the requirements of design and relevant specifications, must be rectified and re-constructed. After meeting the requirements of design and relevant codes and standards, the next working procedure can be started. After strict inspection and acceptance, good results have been achieved.
2.2 In the reinforcement engineering construction, we first start with the source of materials. In order to ensure the quality of the project, the steel shall be supplied by Party A and purchased by the Material Supply Department to ensure that the steel is qualified and reliable. After the reinforcement comes into play, the construction unit shall take samples under the witness of the supervision unit for a second interview. It can only be used in engineering after passing the second interview. In the steel binding construction, our project department requires the supervision unit and the building number to conduct on-site supervision on key parts in addition to inspection, so as to prevent the steel bar spacing and lap length from failing to meet the design and specification requirements. Through strict requirements, patrol inspection and strict supervision, the construction unit earnestly carries out the construction according to the construction plan and construction technology. After testing, the reinforcement project basically meets the design and specification requirements. In view of the common quality problems and quality accidents that are easy to occur, learn from experience and adopt the way of issuing engineering change notices in order to solve the problems. For example, the negative reinforcement at the intersection of balcony slab and beam slab is often trampled in construction, which makes the position of negative reinforcement move down and the protective layer of reinforcement increase, which is prone to slab collapse accidents. In view of this problem, my project department pre-controlled in advance and issued the Notice of Structural Layout of Plastic Horse Stool. After taking this technical measure, it is ensured that the reinforcement will not move down and the thickness of the reinforced concrete protective layer will not change. The main test proves that this measure is effective.
3, template engineering
In the process of formwork construction, the construction unit lacks quality consciousness and is unwilling to put into production. Each building only invests in the second-floor formwork, which leads to the removal of the upper formwork when pouring, which has a serious impact on the concrete structure. Our department informed the supervisor to issue a shutdown notice and immediately rectified it. In order to ensure that the appearance quality and geometric size of the concrete after pouring will not change and deform, we require the construction unit to re-compile the form removal plan and make it clear that the upper formwork will be leveled and poured for 24 hours. In the subject acceptance, it basically reached the acceptance standard of visual quality. The project department attaches great importance to the pouring quality of concrete, strengthens the intensity and frequency of patrol inspection at ordinary times, and promptly handles the quality problems found in the inspection, which greatly improves the project quality and effectively curbs the phenomenon of not paying attention to quality.
4, concrete engineering
The concrete used in the construction is commercial concrete. In order to ensure the quality of commercial concrete, the project headquarters changed the original construction from self-purchasing to selecting commercial concrete suppliers, thus ensuring the construction quality, saving the construction cost and supplying it to the construction site. We regularly or irregularly inspect the concrete mixing station to prevent unqualified commercial concrete from entering the construction site, strictly check the slump of concrete on the construction site and control the construction with water. After taking these effective measures, the supply quality of concrete has been guaranteed. Through the detection of small high-rise buildings, the quality of concrete meets the requirements of design and concrete specifications, and all of them are qualified.
5, masonry engineering
In order to ensure the quality of masonry engineering, we have seized the following links:
5. 1 according to the design and specification requirements, place the wall Rachel reinforcement. In the construction, the method of planting steel bars in the concrete wall is adopted and placed along the wall. We mainly check whether the steel bars are firm. During the inspection, it was found that the parts where the reinforcement was not firm and remained for a long time had to be removed and reinforced again, and good results were achieved.
5.2 The window sill beam must be cast on the outer wall between windows. For example, in the construction of the external wall on the first floor of the 7th floor, the construction unit failed to carry out the construction according to the requirements of the scheme, and then poured it first. This phenomenon was immediately stopped and rectified. The window sill wall that has been built has been demolished, and the window sill beam can not be laid until it meets the requirements. Through strict treatment, the result is very effective, which makes the construction unit pay attention to it, reduces similar phenomena in other buildings, and greatly improves the quality of masonry engineering.
5.3 When building the interior wall, in order to prevent the settlement and cracks of the wall, it is not allowed to build continuously under the beam and fill it with mortar. But leave a height of 200㎜ under the beam according to the standard atlas and specifications. Masonry mortar has a certain strength, and after meeting the technical intermission time, it shall be laid obliquely with cement bricks and compacted with masonry mortar. In the actual construction, most of the construction units did not carry out the construction as required, and the project department strengthened the patrol inspection, held a meeting and put forward strict requirements. If the construction is not carried out in accordance with the atlas and specifications, it will be demolished, refilled and stopped for rectification. With this compulsory measure, only after plastering the inner wall can cracks rarely appear at the joint between the wall and the beam.
6, whitewash project
6. 1 Now our project department has entered the interior wall plastering project, and only small and high-rise buildings 7, 10, 14 and 15 have entered the interior decoration stage.
6.2 The most common quality fault of interior wall plastering is that the joint between wall and beam is prone to through cracks. In order to avoid this kind of common fault, the construction unit is required to paste the joints with steel mesh screen, and only after passing the inspection can it enter the plastering process.
6.3 In order to ensure the engineering quality of interior wall plastering and not to leave hidden dangers for future users, we will cooperate with the supervision and construction unit? One room, one exam? According to the requirements, before plastering, the ash cake should be prepared and the floor control line should be played well, so as to ensure the engineering quality of plastering, and more importantly, it can provide users with a reliable guarantee to ensure that there will be no quality problems after renovation.
6.4 Headquarters, Planning Department and Material Supply Department review and determine the internal wall insulation practices. Supervise the construction in strict accordance with the operation process.
7. Exterior wall tiles
In order to meet the requirements of external wall construction, before plastering, the construction unit is required to properly handle the plastering base, chisel out the concrete expansion template, clean up the polluted template, hang vertical lines from top to bottom, then screed and paste ash cakes, paste steel wire mesh at the junction of column and beam, and do a good job of quantity after acceptance, and then plaster can be started to ensure the overall flatness of the wall. Check whether there is an empty drum at the bottom before tiling, and rectify it in time if found, so as to ensure the construction quality of ceramic tiles.
8, roof insulation and waterproof engineering
8. 1 Roof insulation: use new waterproof material lightweight concrete to find slope. It is planned to start construction of 7 10, 14 and 15 small high-rise buildings this month.
8.2 Roof waterproofing: Roof waterproofing is the most prone to leakage, which is a common quality problem. In order to prevent the occurrence of such common quality defects, on the basis of summarizing other engineering experiences, the supervisor of the building number is required to supervise the whole process, inject water after the waterproof project is completed, and conduct a 48-hour water storage test. Until there is no leakage point, it is qualified.
9. Install aluminum-steel windows, security doors, fire doors and manhole doors for pipelines.
9. 1 At present, there are four small high-rise buildings installed in windows. In order to prevent installation deviation of various doors and windows before installation, it is difficult or difficult to readjust after installation. If the installation subcontracting construction unit carries out the installation without inspection and acceptance, the installation construction unit shall be responsible for the adjustment. If the general contracting construction unit does not actively cooperate with the acceptance work or forcibly requires the installation construction unit to install after the acceptance is unqualified, the general contracting construction unit shall be responsible for the quality defects, draw a clear responsibility and lay the foundation for the installation project.
9.2 In order to control the quality of the installation project, ensure the quality of raw materials and processed finished products are qualified. After the finished product comes into play, the foundation department shall do a good job of embedding mortar under the window to ensure that the mouth under the window is plugged, and the installation can be started only after it is qualified.
9.3 In order to prevent air leakage, dew condensation, frost prevention, mildew prevention and water seepage, our project department requires site supervision to strengthen the inspection of foaming and window frame gluing. The person in charge of the building number stepped up the inspection frequency, found unqualified foaming parts and unqualified window positions, and asked the construction unit to dismantle the original foaming and glue, re-foam and glue, and plaster and tile construction can only be carried out after inspection.
10, installation project
10. 1 according to the characteristics of residential installation project, our project department requires the construction unit to pay attention to the following two aspects when compiling the construction plan: first, the construction preparation work, and second, the planning of the construction activity process. There are many cooperation in construction: the project is constructed by several construction units at the same time. In the process of construction, the installation project must closely cooperate with many construction teams such as weak current installation, fire protection installation and interior decoration to ensure that the construction progress and quality of the project meet the requirements stipulated in the contract.
10.2 Pre-installation works. In order to improve the quality of construction preparation and speed up the progress of construction preparation, it is necessary to strengthen the coordination among the construction unit, design unit, supervision unit and general contracting construction unit, achieve a unified pace and do a good job in construction preparation.
10.3 technical preparation; Driven by Manager Yin, all professionals in the project department are familiar with and review the construction drawings carefully, understand the designers' intentions, combine the construction drawings of water, electricity, ventilation, air conditioning and related weak electricity, and make vertical and horizontal comparison and contact, so that the water, electricity and ventilation professions can be combined and compared with each other. If unreasonable or questionable places are found, they shall be recorded in time as the content of the joint review of drawings in the future, and the joint review records shall be kept as data. Understand the positions of pre-embedded holes and pipelines on the drawings of water, electricity and ventilation specialties, and check the elevation and coordinates of the holes reserved by the general contractor in combination with the construction drawings of civil structures to ensure that the construction of the installation project is not affected by the reserved holes. Prepare the construction drawing budget, list the workload of each sub-project, determine the amount of materials, labor and machines used in each sub-project in the installation project, and summarize them into tables to provide reliable theoretical basis for material preparation. Reviewing the technical scheme of installation project construction and determining technical measures to ensure reasonable and advanced construction technology can improve the construction progress and shorten the construction period. Make specific safety technical disclosure records. The disclosure content should be specific, clear and targeted, so as to ensure the construction safety and quality of the installation project meet the specification requirements.
Fourth, control afterwards, sum up experience, choose the best from the rough, learn lessons and make great progress.
At present, four small high-rise main structures have been accepted, and only 70% of the high-rise main structures have been completed. However, there are still many problems that need to be overcome and corrected in order to improve and bring the governance level to a new level.
1. To further improve and refine various rules and regulations, we should not rely on people to manage people, but rely on rules and regulations to restrain and regulate people's behavior, and rely on systems to urge all managers to work actively, not passively, so as to truly achieve it? Everything is in charge, everything is in charge, there are rules to follow, and everything is well documented? .
2, strengthen business training, use spare time to study, especially to learn and master the use of new standards, new norms, new technologies, new materials, so that their knowledge can be updated. At the same time, study the project budget, carefully check the engineering quantity of the construction unit, and reduce the cost of the enterprise. Make a contribution.
3. After the project is confirmed, should I enter? Plan early, arrange early? This project. Strengthen the coordination and communication between departments, do a good job in all preparations before and after the construction, especially in the early stage, technology, planning, and materials provided by Party A, so as to be prepared and properly connected.
4, coordinate the relationship between all parties, especially with the supervision unit, how to mobilize the enthusiasm of supervisors, give full play to the potential of supervisors, to achieve? Small business owners and big executives? Our governance model is a big problem and subject before us. Because the current actual situation is that the professional level of supervisors employed by supervision units is generally low, the sense of responsibility is poor, the supervision is not in place, and the number of supervision engineers is insufficient, which can not meet the actual needs of project management.
5. Some managers of construction units have poor professional quality and low technical level, which can't meet the actual needs of construction management. For example, they can't work out the construction organization design and construction scheme, copy it, which is not in line with the actual situation of the project, unfamiliar with the construction drawings, do not understand it, and can't guide the construction correctly. Resulting in serious rework. At the same time, the self-inspection system is not perfect, and some units do not conduct self-inspection at all, and only rely on the full-time engineers of the supervision unit and the project department to check the problems before rectification. It not only affects the construction period, but also cannot guarantee the quality of the project. Some contractors are unwilling to invest money and materials in the project, and they are shoddy and have low or no quality awareness, which makes the project quality difficult to control. If we don't take some effective measures to reverse the situation in time in actual engineering construction, the consequences will be unimaginable if we rely solely on the cultivation and quality of the contractor. Therefore, it is particularly important to choose an excellent construction team.
6. Although some achievements have been made in the actual project management, there are still some shortcomings and mistakes. We are determined to overcome the shortcomings, sum up experience, constantly enrich and improve ourselves, develop ourselves through exploration and exploration, achieve better performance, repay the support and trust of real estate leaders and superiors, repay the vast number of merchants and society, and contribute our own strength to building a beautiful home and modern residential quarters.
I recommend it carefully.
