As a construction worker, we should seize the opportunity keenly, adapt to the change, strengthen the understanding of new technologies, and apply information technology including BIM system to the management activities of construction projects, so as to be in an advantage in the future competitive trend.
The continuing education of the second-level constructor, which lasted for nearly one month, is coming to an end. Through classroom study, I feel I have gained a lot. The most profound thing is that the lectures of several lecturers are no longer to explain the textbooks sentence by sentence, but to highlight key articles and integrate theory with practice. When explaining the articles or contents of books, I use PPT to demonstrate, citing a large number of practical examples outside the textbooks to explain, with pictures and pictures, and animation to demonstrate at different levels, which is very different from the classes I have participated in many times before. The whole course is not as boring as before, but deeply attracted by the teacher's explanation, so I can always listen to the lecture with great interest and learn some knowledge outside the textbook. Classic and modern, Chinese and foreign architectural features, history and humanities, the implementation status of China's construction industry norms and regulations, so the gains are really great.
There are three books on continuing education, which are huge in content. Therefore, the summary of this study cannot review all the contents. Here, I only make a summary by linking the actual content and feelings of my work with the content of continuing education.
As for the textbook "Architectural Engineering", I talked about "the application of information technology", and I have a deep understanding. The application of information technology in construction project management aims at improving the efficiency of engineering construction activities. With the mature development and popularization of computer technology, the technological achievements of computers are increasingly applied to all walks of life. The construction industry is no exception. As a development trend, informatization is the most direct achievement. With the continuous updating of software, the effect of information processing is getting higher and higher. [ 1]
In the application of information technology, the textbook mentions building information modeling (BIM), which is causing revolutionary changes in the construction industry. A few years ago, when I was a project manager at the construction site, I was exposed to computer-processed information, which was nothing more than CAD drawings, EXCEL forms and documents, which had brought great convenience to project management. However, the development of computer technology is not what it used to be. At present, my work is mainly to deepen drawing design, and I have a deeper understanding of this point, that is, with the continuous upgrading of software, the effect of information processing is getting higher and higher. For example, using BIM design software to design, as long as the model is established first, not only the design scheme can be displayed intuitively, but also the construction drawing can be automatically generated, which greatly improves the drawing efficiency. For example, if all related majors adopt BIM technology for design. Then the collision can be automatically checked by the system to avoid the phenomenon of "wrong, missing, missing and colliding" in the design. In our company, Tekla Structures and rhinoceros software have been used to deepen drawing design and bidding, and we have cooperated with other related professional companies on this kind of model software, which greatly improves the work efficiency.
1, application of modeling software in deepening drawing work;
For example, in the design of the metal roof wall of Wuxi Grand Theatre, because the metal roof and the wall are integrated, smooth transition and in the shape of an inverted hyperboloid, it is combined with the aluminum curtain wall with hyperboloid on both sides of the metal roof wall, while the main steel structure is a hyperboloid, roughly in the shape of a broken line. If we use traditional CAD software to design, we can't imagine that we can complete such a deepening design. Because each purlin has purlin support plates with different bending radians and different lengths, each profiled steel plate must have different lengths and radians to cover the entire hyperboloid, and it must be consistent with the aluminum curtain wall. Therefore, we adopted rhinoceros software to design according to the requirements of the general contractor. Through this advanced software and the interface with traditional CAD software, we quickly completed the drawing of all purlins, purlins, roof profiled steel plates and other parts of the project, and implemented it smoothly. Cooperate with curtain wall professional units that also use rhinoceros software to successfully complete the connection between the two projects. First of all, on the structural model completed by the steel structure manufacturer, we built the curved surface of the roof panel shell according to the requirements of the metal hyperboloid roof modeling stipulated in the design institute drawings, and built the arc purlin model under the roof panel shell model. All line segments representing each purlin plate are established between the roof plate shell and the steel structure ball joint, and the height of each required purlin plate is calculated by measuring the length of each line segment. Because rhinoceros software can't realize drawing, the drawing of purlin board is still done by CAD. Import the completed purlin and pressed plate models into CAD, mark the parameters of all components on CAD, and form the plane layout and machining details. So as to realize the design of deepening diagram. Of course, this method is an attempt for us to flexibly adopt BIM system. It may not be the most efficient method, but it effectively solves the deep design problem of double-sided roof with broken-line steel structure, and finally successfully applies the processed components to site construction and installation, perfectly realizing the idea of the design institute.
In addition, recently, in Shanghai Commercial Aircraft Project and Changzhou Chater Metal Roof Wall Project, Tekla Structures model software was used to complete the design of purlin tray position and gutter position, and the interface with the drawings of the main steel structure contracting company. Under normal circumstances, the reserved gutter position and purlin plate position should be discharged and provided to the main structure professional unit. This requires a complete understanding of the main steel structure information, and goes deep into the plane layout, elevation, rigid frame diagram, node diagram and other information. These drawings are generally as many as dozens, which is time-consuming and laborious. Using Tekla Structures model software, we can say that we have a comprehensive understanding of the structural information in a few minutes, and the rest of the work is also very labor-saving and fast, which greatly improves the work efficiency.
2. Application of modeling software in engineering quotation;
The quotation needs to calculate the engineering quantity of steel structure first, and the engineering quantity needs to be calculated separately according to different types of components. At present, there are many software for calculating civil engineering in China, which can realize the automatic calculation of reinforced concrete, sandstone and other materials according to the design CAD drawings provided by the design institute, and its function is very powerful. But there is no engineering quantity calculation of steel structure drawings. It is also very hard to calculate the engineering quantity of steel structure through a picture. But in some cases, using BIM technology to do rough imitation and deep design can also complete such a task in a short time, and I have tried to do so. In some buildings (buildings with overall modeling conditions), the efficiency can be greatly improved by manually adding other components. On the Tekla Structures model software platform, it is very convenient to set some structural parameters. After setting the parameters according to the structural drawings of the design institute, the software can automatically generate the consumption list of different components as the quotation basis, which is very convenient.
This alternative method is sometimes very effective, depending on whether the time spent on modeling can be shortened enough to reduce the time spent on the whole calculation process, otherwise it will not be worth the candle.
The history of BIM technology is not long, but it has formed many effective application modes. BIM technology can finally facilitate multi-participants and multi-professionals in building engineering to share information and work together, and promote the improvement of work efficiency and quality. BIM is a technology that has only been applied in recent years. In some developed countries, the application of BIM technology has become very common. At present, this technology has been used in China and the conditions are becoming more and more mature.
Thesis on continuing education of construction workers. How to improve the professional quality and personal quality of builders
At present, with the increase of construction projects and fierce competition in the industry, in order to catch up with the progress and reduce the cost in the construction process, quality control and safety control may be ignored, and quality and safety control is only the focus of a builder's work. In recent years, there are countless quality accidents of various construction projects reported by the media. In the training and study, teachers also cited many examples of engineering quality and safety accidents. In the final analysis, it is because we can't be strict in the construction process, we didn't carry out the construction according to the predetermined construction plan, we didn't strictly control it in the construction process, and the professional quality of the construction workers themselves was not excellent. As the teacher said in his study, some project managers often say that the workers have done nothing well, but they can't tell how to do it, how to guide the workers in construction, and they can't convince people by reasoning.
Second, the project management and control
Construction project management control is a multi-level and all-round management control. Whether the project quality is qualified, whether the safety is up to standard and whether the cost is reasonable reflects the quality of project management. Only by doing a good job in the management and control of construction projects can we achieve the management goal of high quality, safety and efficiency.
Personally, I think project management and control is mainly divided into the following aspects:
1, engineering safety management and control
Safety management is one of the important components of construction project management, and it is a target management involving the personal safety of production personnel, which should be highly valued. During the five-day training and study, the teacher talked about safety in almost every class. If you don't pay attention to safety management, once it happens
Safety accidents bring disaster to injured construction workers and great misfortune to families; Second, construction enterprises should stop work for rectification and pay huge economic compensation, and the compensation standard is increasing every year, which affects the corporate image and economic benefits. Third, it causes employees' ideological and emotional depression and affects their work enthusiasm. Therefore, the responsibility for safe production is great. Safety mainly depends on the system to manage people. Strict implementation of the responsibility system for production safety, so that each post has its own responsibilities, establish and improve full-time safety institutions, strengthen the leadership of the safety department, and strictly implement the safety inspection system. By formulating the responsibility system for production safety, we can realize "things have their owners and people have their responsibilities" in production safety.
2. Project schedule control
Project schedule control plan, implement, check and coordinate the work sequence and duration of each stage, and track, check, analyze, adjust and control the project construction progress under the guidance of careful and reasonable schedule. The ultimate goal of schedule control is to ensure the realization of the project time target. In order to carry out the project construction in a planned way, it is necessary to make a progress plan and carry out the construction as planned.
3, project quality management and control
The construction quality assurance system needs to establish the target system of project quality management and control, reasonably divide posts, and formulate the relevant systems of quality management system, on-site construction quality management and control points and measures according to the construction management scope and engineering characteristics. The operation of construction quality assurance system should be based on quality plan, process management and PDCA cycle principle.
