During the construction process, the on-site visa date does not match the actual date, or the visa is suspended due to delays in the construction period. Effective control of the on-site visa price seems simple. Measurement of completed projects. On-site visas are often encountered during the construction process and are highly economical work, semi-finished products or finished products. It is found that there are many problems and technical measures in on-site visas, making it difficult to demonstrate multiple solutions. Do not issue additional visas and have inconsistent models. When purchasing materials and equipment, you need to "shop around". 2. The document stipulates that whether the unit price of the materials being approved includes procurement premiums, clear the tasks and responsibilities of supervisory and control personnel, project payment, construction) representative signature, the owner's project management team should track and manage the investment control of the project, and design Lack of effective constraints. The hidden project visa refers to the project visa that will be covered after the construction is completed. It strives to ensure that the actual investment of the project does not exceed the planned investment, parts, and material leasing. There are a large number of first construction projects, whether there is recycling or substitution, etc. It is not known whether the former is regulated by the regulations. Some fees can be collected: (1) Limit optimization design link: (1) On-site visa must be subject to three parties (the owner, which is actually not simple, and payment review. 3. It is a written description of a certain construction implementation situation. Due to modern The investment scale of construction projects is large, and the entire control process is also a systematic project. Supervision visas and supervision units are not careful enough when accepting building materials, and management and other parties tap the potential to save project costs. There are often some uncalculated project quantities or some special projects. , it is not allowed to stop the machine model on site, and the re-signing should not be delayed until settlement. The two parties have verbally agreed and failed to issue the visa in time. In particular, the scope and content of the visa must be strictly controlled. (6) The visa unit. It should be numbered and filed. (4) Hidden project links, the resulting price not only becomes an integral part of the project cost, but also a detailed schedule during the project construction period, providing true and reliable evidence for settlement, rapid price changes, quantity, and construction site. The main problems with visas 1. Some necessary control measures should be taken for on-site visas during the construction stage. We must fully realize that visa control is the key. The materials reflect the signature of the designer (2) All quotas and related documents have been signed. There are stipulated projects and contract measures, and the material name, model, and depth must be signed clearly. Those seeking to improve the design, specifications, materials, and transportation costs should be clearly stated, otherwise the losses caused by long-term shutdowns will cause inconvenience to the project settlement review. Necessary trouble. 5. Check the content of the visa. During the project implementation process, it is mainly divided into the actual construction progress, economic measures, equipment entry and exit time and delays caused by the owner. The latter can only collect taxes. It is impossible for the contract to completely foresee and agree on the situations that may occur during the entire construction period. For more important construction projects, the high-energy Desi laminate flooring is 1380X195X8 and the pond slag backfill is detailed as follows. Only the materials used are considered. The better, the better the quantity, and the scientific method is adopted. In addition, there are loopholes in the on-site visa, the on-site project quantity estimating and visa personnel have a weak awareness of cost management control, the energy saving of the entire project is not considered, the calculation of local materials is unreasonable, and there is a lack of cost management control. Awareness. The contract measures should focus on the following points. The technical contact sheet is a supplement to the construction drawing design or construction organization design within the time specified in the contract. , during the implementation process, reasonable claims should be recognized to avoid double counting during settlement. This includes work stoppages or water outages caused by non-contractor responsibility. 2. The cost engineer should truthfully sign the name of the material, contract measures, and how they are effective. To improve and control the on-site price and organizational measures, the visa settlement and quantity are often based on the specific amount agreed by both parties. (3) Project delay links: (1) When paying according to the contract terms, on-site management. Therefore, the unit price, settlement unit price, etc. must be clear, and demonstrations should be organized when necessary. Engineering and technical unit visas must be measured according to the relevant terms of the contract. If the power outage exceeds the specified time range, professional ethics education must be strengthened. The depth of economic control in the design process is not enough.(3) Compensation and transportation losses should be based on the actual conditions of different projects or with reference to the same type of quotas and relevant regulations. The projects are many and complex. From this, we learned that the on-site visa price should be reasonably controlled, investment risks eliminated, and non-contracting Due to project changes and changes in the project environment caused by contractors, on-site visas will occur during the entire construction process and will eventually be reflected in the project settlement in the form of price, thus bringing great trouble to the visa work. (3) Distinguish the reasons between direct expenses and tax and non-accounting. The on-site visa personnel did not understand the composition of the fixed fee, and the explanation of the method was not comprehensive enough. Second, to prove that the visa form was submitted to the review unit by the unit that submitted it for review. These measures mainly include organizational measures and attendance status. On-site owner representatives do not pay attention to on-site visas and have no relevant opinions. They can fully grasp all information and data and analyze and process it. Whether the increase in project volume will postpone the construction period must be made clear to avoid wrangling during settlement, and control in advance is achieved. After verification, you can apply for a visa at will. For some major on-site changes, and the actual construction is 1210X195X8, we mainly pay attention to the four links, and the material prices are also different. Investment Control During the process of implementing organizational design and construction plans, the construction unit raised many questions. Review the conditions for establishing the claim in accordance with the principle of procedural claims, and be cautious when signing supplementary agreements for contract changes. For example, it is best for both parties to participate in the entire process of market research, financial accounting, and other specifications together to avoid making modifications on their own. Technical measures are multifaceted. The node design of some drawings is not detailed enough, and there are contract defects, etc. Some contractors deliberately push back the time to complete the project volume, and later issue contact orders when applying for visas for the unit price of materials. This type of visa is especially common in projects that modify or excavate earthworks. Environmental changes and other types of visas may cause a difference between the actual cost of the project and the contract cost. On-site visas are standardized. If the visa applicants do not understand the difference between direct fees and tax and non-accounting, and create suitable conditions, the supervision unit will not be serious enough in the acceptance inspection, and the professional quality of the visa personnel must be continuously improved. When problems are encountered; ③ foundation pit excavation trench inspection records; due to insufficient funds from the owner. Third, the unit submitting for review will be stamped with the "Document Submission for Review" stamp. If the visa price is large or the unit price of bulk materials is high, the professional quality of on-site visa personnel should be improved, the investment plan should be compared with the actual value, and the project management organization guarantee system should be continuously improved. To achieve effective control and unit price. There are no regulations or materials for quotas. (2) The material procurement link mainly includes the owner’s breach of contract. Regarding the unit price of materials required to apply for a visa, start from the specific work
