First, the "two skins" problem in the preparation and implementation of the construction organization design (scheme)?
1. On the one hand, because no one is willing to do technology, there is a serious loss of technical management personnel, the quality of engineering and technical personnel is not high, and the field technical management strength is weak. Fresh graduates should be added to the technical department first. Due to lack of experience, the compiled scheme can't guide the construction and lacks maneuverability, forming a vicious circle of "you make it yourself and he does it himself". The improvement of this situation needs to be solved from the following aspects: ① Pay attention to the role of technology management in construction production, strengthen the power of technology management, improve the status of scientific and technological personnel, and don't just shout "science and technology are the primary productive force" as a slogan, just as a banner.
(2) Multi-organization technical training is not only the training of norms and regulations, but also the training of safety and management. In the aspect of construction technology, we should increase the opportunities of mutual communication with the outside world and improve the comprehensive quality of construction organization design (scheme) compilers.
③ Pay attention to the cultivation of compound talents and implement the rotation system for engineers and technicians at the same level; The general construction scheme can be compiled by the competent foreman, guided by the technical department and reviewed by the technical director, so as to improve the writing ability of the project management personnel and make the construction scheme better combined with the site.
(4) Improve the participation consciousness of all engineers and technicians, divide the responsibilities of construction organization design, and improve the quality of construction organization design. This work needs the strong support of the project manager to urge all responsible personnel and departments to complete it together, so as to avoid the lack of guidance and operability of the construction organization design due to the fact that the technical department did not combine the actual situation of the project in the process of compiling the construction organization design.
(5) After the preparation of the construction organization design is completed, all departments and offices of the project management department shall conduct audit and countersign, so as to deepen the understanding of each department on the construction organization design. Adopt multi-cycle discussion to enhance the operability of the group (scheme). Before the construction of each subdivisional work, the project technology department should organize engineers and technicians to learn the construction scheme, so as to improve the consistency of technical disclosure and construction scheme.
2. On the other hand, due to insufficient preparatory work, hasty preparation time, lack of information materials, serious repetitive work, rough content of construction organization design (scheme), few detailed nodes, and lack of construction control measures for key parts. The improvement of this situation needs to be solved through the following improvements:
① By striving for the Great Wall Cup of Beijing Structure, the structural construction organization design (scheme) has certain format standards, but the scheme requirements for the Great Wall Cup of Beijing Structure are different every year. In addition, there is no uniform format and requirements for the decoration construction scheme, and the standards of each company, each project and each sub-project are not uniform. Most of them rely on the previous construction experience and the construction experience of the construction team, lacking the accumulation and innovation of construction technical data. It is suggested that the group company establish a technical database to reduce the repetitive work of technicians in the process of compiling the construction organization design (scheme), and it is hoped that the group company will concentrate its technicians on compiling the standardized format of the construction scheme; At the same time, collect the construction methods of various sub-projects, formulate unified enterprise construction standards, and comprehensively promote them within the scope of the whole group company.
(2) All majors should train technical experts, solve difficult problems, organize expert discussions, and sort out preventive and corrective measures for difficult problems.
③ Collect more detailed node practices and form a detailed node practice database, so as to make the compilation of construction organization design (scheme) "complete nodes and clear contents", thus better guiding construction production.
(4) After the implementation of the construction organization design (scheme), the performance of the construction scheme should be summarized in time, and further improvement suggestions should be put forward to further improve the quality of the construction scheme.
3. The person in charge of the project has a low level of knowledge, lacks understanding of new technologies and new materials, follows the traditional construction technology by experience, and lacks the spirit of innovation. However, the promotion and application of new technologies and materials can not be strongly supported, and the promotion of new technologies and materials can not be realized from the technical management and strength. The improvement of this situation needs to be solved from the following aspects: ① Promote the talents with high professional knowledge and good management and innovation to the main leadership positions, and promote the improvement of the scientific and technological level of enterprises.
(2) Collect more information about the application of new technologies and new materials, and compare their performance and price, so as to analyze the application of a new technology and new materials in the Group and reduce the blindness of the application of new technologies and new materials.
(3) Encourage the popularization and application of new technologies and materials, and start from the pilot, so as to achieve "close monitoring, scientific analysis and serious summary", analyze the differences between new technologies and materials and traditional processes, and popularize new technologies and materials with guaranteed quality and cost savings on a large scale.
Second, the "two skins" problem of technical scheme and project cost?
(1) Understand the materials and equipment of the company to make full use of resources.
(2) When preparing the technical scheme, the selection of materials (cost performance) should be fully considered, and the materials department and the management department should check it.
(3) While compiling the "construction organization design" of the project, the "project cost design" should be compiled, with the project manager or executive manager taking the lead, and the engineering department, ministry of materials and equipment, the operation department and the technology department controlling the manufacturing cost of the project.
Third, how to make technical and economic evaluation and optimization of the construction scheme?
(1) In the process of drawing up the scheme, the technical department and the engineering department fully considered the characteristics of the project, combined with previous construction experience, put forward a variety of construction methods, and formulated a preliminary construction scheme.
(2) After the preparation of the preliminary construction scheme is completed, organize the technical department, ministry of materials and equipment, the operation department and the engineering department to evaluate the construction methods and materials selected in the construction scheme, and the engineering department and the operation department calculate the construction physical quantity, while ministry of materials and equipment and the operation department calculate the unilateral cost according to the selected materials.
(3) According to the calculation results, compare the comprehensive unilateral cost of several construction methods, and choose the construction method with reasonable method and moderate price. The technical department finally determines and distributes the construction plan, and the engineering department supervises the implementation.
(4) After the construction is completed, the engineering department will make statistics on the final physical quantity, the final material consumption and material loss, ministry of materials and equipment will make statistics on the final material price, the sales department will summarize and analyze the final manufacturing cost, and the technical department will collect all materials completely, and submit electronic documents to the technical department of the company to form company information.
(5) The technical department of the company summarizes similar information of each project and inputs it into the company information platform.
Four, how to do a good job of bidding and construction organization design after winning the bid?
(1) After winning the bid, the technical department of the company will send the bidding construction organization design to the project management department in the form of electronic files, and the project chief engineer will organize discussion and research on the bidding construction organization design.
(2) According to the actual situation of the project, the bidding team analyzes the construction drawings and the actual situation on site, lists the difficulties and characteristics of the project construction, formulates targeted construction technical measures according to the construction quality requirements, and selects the economic and reasonable construction method according to the comparison.
(3) Submit the sorted construction scheme to the technical department of the company for approval. And according to the construction organization design, prepare special construction plan.
